◼ ACCESSORIES
Check that the following parts are included in addition to the main unit:

BEFORE USING

Pay attention to the following before using this unit:

• Moving the set
  To prevent short circuits or damaged wires in the connection cords, always unplug the power cord and disconnect the connection cords between all other audio components when moving the set.

• Before turning the power switch on
  Check once again that all connections are proper and that there are not problems with the connection cords. Always set the power switch to the standby position before connecting and disconnecting connection cords.

• Store this instructions in a safe place.
  After reading, store this instructions along with the warranty in a safe place.

• Note that the illustrations in this instructions may differ from the actual set for explanation purposes.

CAUTIONS ON INSTALLATION

Noise or disturbance of the picture may be generated if this unit or any other electronic equipment using microprocessors is used near a tuner or TV.
If this happens, take the following steps:

• Install this unit as far as possible from the tuner or TV.
• Set the antenna wires from the tuner or TV away from this unit’s power cord and input/output connection cords.
• Noise or disturbance tends to occur particularly when using indoor antennas or 300 Ω /ohms feeder wires. We recommend using outdoor antennas and 75 Ω /ohms coaxial cables.
  For heat dispersal, leave at least 10 cm of space between the top, back and sides of this unit and the wall or other components.

CAUTIONS ON HANDLING

• Switching the input function when input jacks are not connected
  A clicking noise may be produced if the input function is switched when nothing is connected to the input jacks. If this happens, either turn down the MASTER VOLUME control or connect components to the input jacks.

• Muting of PRE OUT jacks, HEADPHONE jack and SPEAKER terminals
  The PRE OUT jacks, HEADPHONE jacks and SPEAKER terminals include a muting circuit. Because of this, the output signals are greatly reduced for several seconds after the power switch is turned on or input function, surround mode or any other-set-up is changed. If the volume is turned up during this time, the output will be very high after the muting circuit stops functioning. Always wait until the muting circuit turns off before adjusting the volume.

• Whenever the power switch is in the STANDBY state, the apparatus is still connected on AC line voltage.
  Please be sure to unplug the cord when you leave home for, say, a vacation.

AM loop antenna assembly FM antenna adapter assembly

Note to CATV system installer:
This reminder is provided to call the CATV system installer’s attention to Article 820-40 of the NEC which provides guidelines for proper grounding and, in particular, specifies that the cable ground shall be connected to the grounding system of the building, as close to the point of cable entry as practical.
Notes:

• Do not connect two FM antennas simultaneously.
• Even if an external AM antenna is used, do not disconnect the AM loop antenna.
• Make sure AM loop antenna lead terminals do not touch metal parts of the panel.

Connecting the external input (EXT. IN) jacks

• These input jacks are for inputting multi-channel audio signals in high definition MUSE 3-1 format, multi-channel audio signals from an MPEG multi-channel decoder, or future multi-channel sound format, etc.
• When making connections, also refer to the operating instructions of the other components.

When connecting a high definition (MUSE 3-1 format) component, use a separately sold mono/stereo cable if the surround channel output is monaural.

Speaker system connections

• Connect the speaker terminals with the speakers making sure that like polarities are matched ( with , with ). Mismatching of polarities will result in weak central sound, unclear orientation of the various instruments, and the sense of direction of the stereo being impaired.
• When making connections, take care that none of the individual conductors of the speaker cord come in contact with adjacent terminals, with other speaker cord conductors, or with the rear panel.

NOTE:
NEVER touch the speaker terminals when the power is on.
Doing so could result in electric shocks.

Speaker Impedance

• Speakers with an impedance of from 6 to 16 Ω /ohms can be connected for use as surround and center speakers.
• Speakers with an impedance of 6 to 16 Ω /ohms can be connected for use as front speakers.
• Be careful when using two pairs of front speakers (A + B) at the same time, since use of speakers with an impedance of less than 8 Ω /ohms will lead to damage.
• The protector circuit may be activated if the set is played for long periods of time at high volumes when speakers with an impedance lower than the specified impedance are connected.

Connections

• When making connections, also refer to the operating instructions of the other components.

• Precautions when connecting speakers

If a speaker is placed near a TV or video monitor, the colors on the screen may be disturbed by the speaker’s magnetism. If this should happen, move the speaker away to a position where it does not have this effect.

Protector circuit

• This unit is equipped with a high-speed protection circuit. The purpose of this circuit is to protect the speakers under circumstances such as when the output of the power amplifier is inadvertently short-circuited and a large current flows, when the temperature surrounding the unit becomes unusually high, or when the unit is used at high output over a long period which results in an extreme temperature rise.
  When the protection circuit is activated, the speaker output is cut off and the power supply indicator LED flashes. Should this occur, please follow these steps: be sure to switch off the power of this unit, check whether there are any faults with the wiring of the speaker cables or input cables, and wait for the unit to cool down if it is very hot. Improve the ventilation condition around the unit and switch the power back on.
  If the protection circuit is activated again even though there are no problems with the wiring or the ventilation around the unit, switch off the power and contact a DENON service center.

Note on speaker impedance

• The protector circuit may be activated if the set is played for long periods of time at high volumes when speakers with an impedance lower than the specified impedance (for example speakers with an impedance of lower than 4 Ω/ohms) are connected. If the protector circuit is activated, the speaker output is cut off. Turn off the set’s power, wait for the set to cool down, improve the ventilation around the set, then turn the power back on.

NOTES:

• The on-screen display signals are output with priority to the S-VIDEO MONITOR OUT jack during playback of a video component. For example, if the TV monitor is connected to both the AVR-2801/981’s S-Video and video monitor output jacks and signals are input to the AVR-2801/981 from a video source (VDP, etc.) connected to both the S-Video and video input jacks, the on-screen display signals are output with priority to the S-Video monitor output. If you wish to output the signals to the video monitor output jack, do not connect a cord to the S-VIDEO MONITOR OUT jack. (For details, see page 22.)
• The AVR-2801/981’s on-screen display function is designed for use with high resolution monitor TVs, so it may be difficult to read small characters on TVs with small screens or low resolutions.
• The setup menu is not displayed when “HEADPHONE ONLY” is selected.

Speaker system layout
Basic system layout

• The following is an example of the basic layout for a system consisting of six speaker systems and a television monitor:

Before setting up the system

1. Check that all the connections are correct, then turn on the main unit’s power.
2. Display the System Setup Menu.

Setting the type of speakers

• The composition of the signals output from the different channels and the frequency response are adjusted automatically according to the combination of speakers actually being used.

1. At the System Setup Menu select “Speaker Configuration”.
2. Switch to the speaker configuration screen.
3. Set whether or not speakers are connected and, if so, their size parameters. • To select the speaker • To select the parameter
4. Enter the setting. When “Front” is set to “Large” and “Subwoofer” is set to “Yes” the set switches to the subwoofer mode.

NOTE:

• Select “Large” or “Small” not according to the actual size of the speaker but according to the speaker’s capacity for playing low frequency (approximately 80 Hz and below) signals. If you do not know, try comparing the sound at both settings (setting the volume to a level low enough so as not to damage the speakers) to determine the proper setting.
• Parameters
  Large…… Select this when using speakers that can fully reproduce low sounds of below 80 Hz.
  Small…… Select this when using speakers that cannot reproduce low sounds of below 80 Hz with sufficient volume.
  When this setting is selected, low frequencies of below 80 Hz are assigned to the subwoofer.
  None…… Select this when no speakers are installed.
  Yes/No…. Select “Yes” when a subwoofer is installed, “No” when a subwoofer is not installed.
• If the subwoofer has sufficient low frequency playback capacity, good sound can be achieved even when “Small” is set for the front, center and surround speakers.
• For the majority of speaker system configurations, using the SMALL setting for all five main speakers and Subwooofer On with a connected subwoofer will yield the best results.

Setting the subwoofer mode

1. Select the bass signal playback mode.
2. Enter the setting. The System Setup Menu reappears.

NOTES:

• In the Subwoofer mode screen, you have the flexibility to choose how bass information is distributed to your speakers if you have large front left and right speakers and a subwoofer as part of your home theater speaker system.
• By selecting the “LFE + Main” option, you will be sending the same bass frequencies to both the front left, front right, and the subwoofer speakers simultaneously. Depending upon your room size and shape, this can create a more evenly distributed bass around the room or sometimes actually decrease the amount of bass in the room due to low frequency cancellations.
• If the “LFE” option is selected, bass from the large front left and front right speakers goes only to the front left and front right speakers. Bass going to the subwoofer comes from the LFE signal and any speakers which you have designated as “Small.” This   election is preferred asit reduces the chances of bass cancellations in the room.
• Once you have positioned all of your speakers in the room, choose the option which gives you the most solid sounding bass.
• When the subwoofer is set to “Yes”, bass sound is output from the subwoofer regardless of the subwoofer mode setting in surround modes other than Dolby/DTS.

Setting the delay time
Input the distances from the listening position to the speakers and set the surround delay time.
Preparations:
Measure the distances from the listening position to the speakers (L1 to L3 on the diagram at the right).
L1: Distance from center speakers to listening position
L2: Distance from front speakers to listening position
L3: Distance from rear speakers to listening position

NOTES:

• Set the center speaker so that the distance to the front speakers (left and right) or the subwoofer is the same (L2 = L1) or so that the difference in the distance (L2 – L1) is 5 feet (1.5 meters) or less.
• Set the surround speakers (left and right) so that the distance to the front speakers (left and right) or the subwoofer is the same (L2 = L3) or so that the difference in the distance (L2 – L3) is 15 feet (4.5 meters) or less.

1. At the System Setup Menu select “Delay Time”.

2. Switch to the Delay Time screen.

3. Select the desired unit, meters or feet.
   Select (darken) the desired units, “Meters” or “Feet”.

4. Once “Meters” or “Feet” is selected in step 3, the Delay Time screen appears automatically

5. Select the speaker to be set.

6. Set the distance between the center speaker and listening position.
   The distance changes in units of 1 foot (0.1 meters) each time the button is pressed. Select the value closest to the measured distance. * If “Yes” is selected for “Default”, the settings are automatically reset to the default values.

• If you set an invalid distance, a CAUTION notice, such as screen right will appear. In this case, please relocate the blinking speaker(s) so that its distance is no larger than the value shown in highlighted line.
• Set in such a way that the distance to the center speaker is the same as or up to 5 feet (1.5 meters) shorter than the distance to the front speakers and the subwoofer.
• Set in such a way that the distance to the surround speakers is the same as or up to 15 feet (4.5 meters) shorter than the distance to the front speakers and the subwoofer. 7. Enter the setting.
  The System Setup Menu reappears.
  The AVR-2801/981 automatically sets the optimum surround delay time for the listening room.

NOTE:

• If the distance unit is changed after the delay time is set, the settings are reset to the factory default values (see page 14).

Setting the channel level

• Use this setting to adjust so that the playback level between the different channels is equal.
• From the listening position, listen to the test tones produced from the speakers to adjust the level.
• The level can also be adjusted directly from the remote control unit. (For details, see page 36.)

1. At the System Setup Menu select “Channel Level”.

2. Switch to the Channel Level screen.

3. Select “Test Tone Mode”.

4. Select the mode.
   Select “Auto” or “Manual”.
   • Auto:
   Adjust the level while listening to the test tones produced automatically from the different speakers.
   • Manual:
   Select the speaker from which you want to produce the test tone to adjust the level.

5. Select “Test Tone Start”.

6. Select “Yes”.

7. a. If the “Auto” mode is selected:
   Test tones are automatically emitted from the different speakers. The test tones are emitted from the different speakers in the following order, at 4-second intervals the first time and second time around, 2second intervals the third time around and on:
   Use the CURSOR buttons to adjust all the speakers to the same volume.
   The volume can be adjusted between –12 dB and +12 dB in units of 1 dB. b. When the “Manual” mode is selected Use the and  cursor buttons to select the speaker from which you want to produce the test tone, then use the and cursor buttons to adjust so that the volume from the different speakers sounds the same.

8. After the above settings are completed, press the ENTER button.
   The “Channel Level” screen reappears.
   Press the ENTER button again, the “System Setup Menu” screen reappears.

* To cancel the settings, select “Level Clear” and “Yes” on the “Channel Level” screen, then make the settings again.
The level of each channel should be adjusted to 75 dB (C-weighted, slow meter mode) on a sound level meter at the listening position. If a sound level meter is not available adjust the channels by ear so the sound levels are the same. Because adjusting the subwoofer level test tone by ear is difficult, use a well known music selection and adjust for natural balance.
NOTE: When adjusting the level of an active subwoofer system, you may also need to adjust the subwoofer’s own volume control.

• When you adjust the channel levels while in the SYSTEM SETUP CHANNEL LEVEL mode, the channel level adjustments made will affect ALL surround modes. Consider this mode a Master Channel Level adjustment mode.
• After you have completed the SYSTEM SETUP CHANNEL LEVEL adjustments, you can then activate the individual surround modes and adjust channel levels that will be remembered for each of those modes. Then, whenever you activate a particular surround sound mode, your preferred channel level adjustments for just that mode will be recalled. Check the instructions for adjusting channel levels within each surround mode on Page 36.
• You can adjust the channel levels for each of the following surround modes: DIRECT, STEREO, 5CH STEREO, DOLBY/DTS SURROUND, ROCK ARENA, JAZZ CLUB, VIDEO GAME, MONO MOVIE, and MATRIX.

• For 4 above, the on-screen display signals are output to the VIDEO MONITOR OUT video signal output jack (yellow) if the monitor TV is not connected to the S-video MONITOR OUT video signal output jack.

REMOTE CONTROL UNIT

• The included remote control unit (RC-881) can be used to operate not only the AVR-2801/981 but other remote control compatible DENON components as well. Furthermore, it is equipped with a function for learning the control signals of remote control units of other manufacturers, so it can also be used to operate non-DENON remote control compatible video components.

Inserting the batteries

1. Remove the remote control unit’s rear cover.
2. Set two R6P/AA batteries in the battery compartment in the indicated direction.
3. Put the rear cover back on.

Notes on Batteries

• Use R6P/AA batteries in the remote control unit.
• The batteries should be replaced with new ones approximately once a year, though this depends on the frequency of usage.
• Even if less than a year has passed, replace the batteries with new ones if the set does not operate even when the remote control unit is operated nearby the set.
• When inserting the batteries, be sure to do so in the proper direction, following the “ ” and “ ” marks in the battery compartment.
• To prevent damage or leakage of battery fluid:
• Do not use a new battery together with an old one.
• Do not use two different types of batteries.
• Do not short-circuit, disassemble, heat or dispose of batteries in flames.
• Remove the batteries from the remote control unit when you do not plan to use it for an extended period of time.
• If the battery fluid should leak, carefully wipe the fluid off the inside of the battery compartment and insert new batteries.
• When replacing the batteries, have the new batteries ready and insert them as quickly as possible.
• The learned remote control signals may be cleared if no batteries are in the remote control unit for about 5 seconds.
  The factory-installed codes are in permanent memory, however.

Using the remote control unit

• Point the remote control unit at the remote sensor on the main unit as shown on the diagram.
• The remote control unit can be used from a straight distance of approximately 7 meters/22 feet from the main unit, but this distance will be shorter if there are obstacles in the way or if the remote control unit is not pointed directly at the remote sensor.
• The remote control unit can be operated at a horizontal angle of up to 30 degrees with respect to the remote sensor.

NOTES:

• It may be difficult to operate the remote control unit if the remote sensor is exposed to direct sunlight or strong artificial light.
• Do not press buttons on the main unit and remote control unit simultaneously. Doing so may result in malfunction.

Learning function

• If your AV component is not a DENON product or it cannot be operated with the preset memory codesets, you can “teach” the AVR-2801/981’s remote control to “learn” the codes from the component’s original remote control.
• The buttons that can be “learned” are the CD, DECK and CDR/MD system buttons (see page 24) and the DVD, VDP, VCR and TV system buttons (see page 27). (For the CD, CDR/MD, DVD, VDP and TV, the A block buttons can also be “learned”, and for the DVD and TV, the B block buttons can also be “learned”.)

1. Press the USE/LEARN selector button with the tip of a pen etc., to set the learn mode. Both the START and LEARNED/TX indicators flash. This unit’s remote control unit

2. Set the program switch to the side to be learned.
   Set to the AUDIO side for the CD, tape deck or CDR/MD position, to the VIDEO side for the DVD, VDP, VCR or TV position.

3. Set the program switch to the position to be learned.

4. Set the remote control units so they are facing each other, then press the button to be learned on this unit’s remote control unit.The indicator stops flashing and the START LED lights.
   The learnable buttons are the buttons which can be operated with the DENON system codes for the CD player, tape deck, CD recorder, MD recorder, the buttons which can be operated with the preset memory for the DVD, VCR, VDP and TV. For the TV only, however, the buttons in the section indicated “A” on the diagram above can also be “learned”. Use these to “learn” TV channels.

5. Check that the START LED is lit, then press the button to be “learned” on the other remote control unit.

This function only works in the Dolby Pro Logic, Dolby Digital and DTS Surround modes.
D.COMP. (Dynamic Range Compression):
Motion picture soundtracks have tremendous dynamic range (the contrast between very soft and very loud sounds). For listening late at night, or whenever the maximum sound level is lower than usual, the Dynamic Range Compression allows you to hear all of the sounds in the soundtrack (but with reduced dynamic range). (This only works when playing program sources recorded in Dolby Digital or DTS.) Select one of the four parameters (“OFF”, “LOW”, “MID” (middle) or “HI” (high)). Set to OFF for normal listening.
LFE (Low Frequency Effect):
Program source and adjustment range

1. Dolby Digital: –10 dB to 0 dB
2. DTS Surround: –10 dB to 0 dB

• When DOLBY DIGITAL encoded software is played, it is recommended that the LFE LEVEL be set to 0 dB for correct DOLBY DIGITAL playback.
• When DTS encoded movie software is played, it is recommended that the LFE LEVEL be set to 0 dB for correct DTS playback.
• When DTS encoded music software is played, it is recommended that the LFE LEVEL be set to –10 dB for correct DTS playback.
  TONE:
  This adjusts the tone control. (See “Surround parameters 2” on page 43 and page 44)

DSP SURROUND SIMULATION

• The AVR-2801/981 is equipped with a high performance DSP (Digital Signal Processor) which uses digital signal processing to synthetically recreate the sound field. One of six preset surround modes can be selected according to the program source and the parameters can be adjusted according to the conditions in the listening room to achieve a more realistic, powerful sound. These surround modes can also be used for program sources not recorded in Dolby Surround Pro Logic or Dolby Digital.

Surround modes and their features

1| ROCK ARENA| Use this mode to achieve the feeling of a live concert in an arena with reflected sounds coming from all directions.
---|---|---
2| JAZZ CLUB| This mode creates the sound field of a live house with a low ceiling and hard walls. This mode gives jazz a very vivid realism.
3| VIDEO GAME| Use this to enjoy video game sources.
6| MATRIX| Select this to emphasize the sense of expansion for music sources recorded in stereo. Signals consisting of the difference component of the input signals (the component that provides the sense of expansion) processed for delay are output from the surround channel.
4| 5CH STEREO| In this mode, the signals of the front left channel are output from the left surround channel, the signals of the front right channel are output from the right surround channel, and the same (in-phase) component of the left and right channels is output from the center channel. This mode provides all speaker surround sound, but without directional steering effects, and works with any stereo program source.
5| MONO MOVIE (NOTE 1)| Select this when watching monaural movies for a greater sense of expansion.

*Depending on the program source being played, the effect may not be very noticeable.
In this case, try other surround modes, without worrying about their names, to create a sound field suited to your tastes.
NOTE 1: When playing sources recorded in monaural, the sound will be one- sided if signals are only input to one channel (left or right), so input signals to both channels. If you have a source component with only one audio output (monophonic camcorder, etc.) obtain a “Y” adaptor cable to split the mono output to two outputs, and connect to the L and R inputs.

NOTE:
Only the DIRECT mode can be used when playing PCM signals with a sampling frequency of 96 kHz (such as from DVD-Video discs that contain 24 bit, 96 kHz audio). If such signals are input during playback in one of the other surround modes, the mode automatically switches to DIRECT.
Personal Memory Plus
This set is equipped with a personal memorize function that automatically memorizes the surround modes and input modes selected for the input different sources. When the input source is switched, the modes set for that source last time it was used are automatically recalled.

• The surround parameters, tone control settings and playback level balance for the different output channels are memorized for each surround mode.

DSP surround simulation

• To operate the surround mode and surround parameters from the remote control unit.

ADDITIONAL INFORMATION

Speaker setting examples
Here we describe a number of speaker settings for different purposes. Use these examples as guides to set up your system according to the type of speakers used and the main usage purpose.

1. Basic setting
   Use this setting if your main purpose is to listen to movie music and when using one set (two speakers) of regular single-way or two-way speakers as the surround speakers. • Set the front speakers with their front surfaces as flush with the TV or monitor screen as possible. Set the center speaker between the front left and right speakers and no further from the listening position than the front speakers.
   • Consult the owner’s manual for your subwoofer for advice on placing the subwoofer within the listening room.
   • If the surround speakers are direct-radiating (monopolar) then place them slightly behind and at an angle to the listening position and parallel to the walls at a position 60 to 90 centimeters (2 to 3 feet) above ear level at the prime listening position.

2. Using diffusion type speakers for the surround speakers
   For the greatest sense of surround sound envelopment, diffuse radiation speakers such as bipolar types, or dipolar types, provide a wider dispersion than is possible to obtain from a direct radiating speaker (monopolar). Place these speakers at either side of the prime listening position, mounted above ear level. • Set the front speakers, center speaker and subwoofer in the same positions as in example (1).
   • Set the surround speakers directly at the sides of the listening position and 60 to 90 centimeters (2 to 3 feet) above ear level.
   • The signals from the surround channels reflect off the walls as shown on the diagram at the left, creating an enveloping and realistic surround sound presentation.

Surround
The AVR-2801/981 is equipped with a digital signal processing circuit that lets you play program sources in the surround mode to achieve the same sense of presence as in a movie theater.
Dolby Surround
(1) Dolby Digital (Dolby Surround AC-3)
Dolby Digital is the multi-channel digital signal format developed by Dolby Laboratories.
Dolby Digital consists of up to “5.1” channels – front left, front right, center, surround left, surround right, and an additional channel exclusively reserved for additional deep bass sound effects (the Low Frequency Effects – LFE – channel, also called the “.1” channel, containing bass
frequencies of up to 120 Hz).
Unlike the analog Dolby Pro Logic format, Dolby Digital’s main channels can all contain full range sound information, from the lowest bass, up to the highest frequencies – 22 kHz. The signals within each channel are distinct from the others, allowing pinpoint  sound imaging, and Dolby Digital offers tremendous dynamic range from the most powerful sound effects to the quietest, softest sounds, free from noise and distortion.

◼ Dolby Digital and Dolby Pro Logic

Comparison of home surround systems| Dolby Digital| Dolby Pro Logic
---|---|---
No. recorded channels (elements)| 5.1 ch| 2 ch
No. playback channels| 5.1 ch| 4 ch
Playback channels (max.)| L, R, C, SL, SR, SW| L, R, C, S (SW – recommended)
Audio processing| Digital discrete processing
Dolby Digital (AC-3) encoding/decoding| Analog matrix processing Dolby Surround
High frequency playback limit of surround channel| 20 kHz| 7 kHz

◼  Dolby Digital compatible media  and playback methods
Marks indicating Dolby Digital compatibility: and .
The following are general examples. Also refer to the player’s operating instructions.

“AUTO”. (Page 32)
DVD| Optical or coaxial digital output (same as for PCM)*2| Set the input mode to “AUTO”. (Page 32)
Others (satellite broadcasts, CATV, etc.)| Optical or coaxial digital output (same as for PCM)| Set the input mode to “AUTO”. (Page 32)

• 1 Please use a commercially available adapter when connecting the Dolby Digital RF (AC-3RF) output jack of the LD player to the digital input jack.
  Please refer to the instruction manual of the adapter when making connection.
• 2 Some DVD digital outputs have the function of switching the Dolby Digital signal output method between “bit stream” and “(convert to) PCM”. When playing in Dolby Digital surround on the AVR-2801/981, switch the DVD player’s output mode to “bit stream”. In some cases players are equipped with both “bit stream + PCM” and “PCM only” digital outputs. In this case connect the “bit stream + PCM” jacks to the AVR-2801/981.

(2) Dolby Pro Logic
Dolby Pro Logic is a multi-channel signal playback system developed by Dolby Laboratories which decodes sources recorded in Dolby Surround into four channels: front left, center, front right and surround (the surround channel is monaural, but is played through two surround speakers). Here, “sources recorded in Dolby Surround” are sources on which surround signals (three channels or more) are recorded onto two channels using Dolby Surround encoding technology. Dolby Surround recording is possible for all two-channel signal sources, including soundtracks on DVDs (*), LDs or hi-fi VCRs (for which stereo signal recording is possible), stereo FM, TV and satellite broadcasts, stereo CD, MD and analog cassette tape recordings. Sources recorded in Dolby Surround are compatible with stereo playback, so they can be played in stereo on regular stereo equipment and in surround with Dolby Pro Logic processing. (DTS and Dolby Digital require special decoders to be played.)
With Dolby Pro Logic, the signal levels of the different channels of the source recorded in Dolby Surround are monitored, channels with higher signal levels are emphasized and the level of the other channels is decreased in order to reinforce the directivity and achieve an effective surround sound.

• DVDs recorded in Dolby Surround include sources recorded in PCM and sources recorded in 2-channel Dolby Digital. For 2-channel Dolby Digital DVD sources, the DVD player’s audio mode is 2-channel Dolby Digital, and the AVR-2801/981’s surround mode is Dolby Pro Logic.

◼ Dolby Pro Logic compatible media and playback methods
Mark indicating Dolby Pro Logic compatibility:
When playing in Dolby Pro Logic, select the input signal according to how the player is connected to the AVR-2801/981, in the same way as selecting the stereo signal (see page 20). Set the surround mode to “DOLBY SURROUND” (see page 37) to play in Dolby Pro Logic.

DTS Digital Surround
Digital Theater Surround (also called simply DTS) is a multi-channel digital signal format developed by Digital Theater Systems.
DTS offers the same “5.1” playback channels as Dolby Digital (front left, front right and center, surround left and surround right) as well as the stereo 2-channel mode. The signals for the different channels are fully independent, eliminating the risk of deterioration of sound quality due to interference between signals, crosstalk, etc.
DTS features a relatively higher bit rate as compared to Dolby Digital (1234 kbps for CDs and LDs, 1536 kbps for DVDs) so it operates with a relatively low compression rate. Because of this the amount of data is great, and when DTS playback is used in movie theaters, a separate CDROM synchronized with the film is played.
With LDs and DVDs, there is of course no need for an extra disc; the pictures and sound can be recorded simultaneously on the same disc, so the discs can be handled in the same way as discs with other formats.
There are also music CDs recorded in DTS. These CDs include 5.1-channel surround signals (compared to two channels on current CDs).
They do not include picture data, but they offer surround playback on CD players that are equipped with digital outputs (PCM type digital output required).
DTS surround track playback offers the same intricate, grand sound as in a movie theater, right in your own listening room.

◼  DTS compatible media and playback methods
Marks indicating DTS compatibility: and .
The following are general examples. Also refer to the player’s operating instructions.

to “AUTO” or “DTS” (page 37). Never set the mode to “ANALOG” or “PCM”. 1
LD (VDP)| Optical or coaxial digital output (same as for PCM) 2| Set the input mode to “AUTO” or “DTS” (page 37). Never set the mode to “ANALOG” or “PCM”. 1
DVD| Optical or coaxial digital output (same as for PCM) 3| Set the input mode to “AUTO” or “DTS” (page 37).

• 1 DTS signals are recorded in the same way on CDs and LDs as PCM signals. Because of this, the un-decoded DTS signals are output as random “hissy” noise from the CD or LD player’s analog outputs. If this noise is played with the amplifier set at a very high volume, it may possibly cause damage to the speakers. To avoid this, be sure to switch the input mode to “AUTO” or “DTS” before playing CDs or LDs recorded in DTS. Also, never switch the input mode to “ANALOG” or “PCM” during playback. The same holds true when playing CDs or LDs on a DVD player or LD/DVD compatible player. For DVDs, the DTS signals are recorded in a special way so this problem does not occur.
• 2 The signals provided at the digital outputs of a CD or LD player may undergo some sort of internal signal processing (output level adjustment, sampling frequency conversion, etc.). In this case the DTS-encoded signals may be processed erroneously, in which case they cannot be decoded by the AVR-2801/981, or may only produce noise. Before playing DTS signals for the first time, turn down the master volume to a low level, start playing the DTS disc, then check whether the DTS indicator on the AVR-2801/981 (see page 38) lights before turning up the master volume.
• 3 A DVD player with DTS-compatible digital output is required to play DTS DVDs. A DTS Digital Output logo is featured on the front panel of compatible DVD players. Recent DENON DVD player models feature DTS-compatible digital output – consult the player’s owner’s manual for information on configuring the digital output for DTS playback of DTS-encoded DVDs.
