Output Setup

  • The output setup menu will display the recommended filter settings from the selection of speakers and subwoofer from your initial Guided Speaker Setup. In this section you can change the setup of speaker and line level outputs to your preferences.

  • Selecting a Lyngdorf speaker will load an equalizing filter designed to optimize the performance of this speaker in relation to the selection of sub speaker selected. Selecting “Custom” will open new settings allowing you to design your own equalizing filter.
    LYNGDORF-TDAI-3400-Tear-Down-The-Living-Room-Was-003

  • To reveal all directly controlled features, select “Custom” speakers and “Advanced” in the output setup.

Main out / main speakers
Select the speakers connected to the speaker outputs of the TDAI-3400:

  • Standard Stereo : For a pair of loudspeakers.

  • Lyngdorf presets : For a pair of Lyngdorf loudspeakers, optimizing their performance with pre-set sound equalizing, crossover, and filters.

  • None : For using the TDAI-3400 as a pre-amp when no loudspeakers are connected.

  • Custom : For a pair of loudspeakers, optimizing their performance with different settings. The following options can be set:

  • Full range lets the signal pass unfiltered (full frequency bandwidth).

  • Crossover, High Pass Filter removes the frequencies below the set crossover frequency. Crossover, Low Pass Filter removes the frequencies above the set crossover frequency.

  • Level lowers the main output level relative to the line output level.

  • Eq allows custom sound equalizing for the main speakers.

  • Distance allows distance alignment (for example from the listening position to left and right speakers).

WARNINGS

  • The speaker output channels cannot be used together in “Bridge Mode”. Never bridge the speaker outputs with another amplifier.
  • Never connect the speaker outputs to the “High Level” inputs of a subwoofer. Never run the amplifier without speaker load unless main output is set to “None”.

Line out / sub speakers
Select how the line outputs will be used. Analog and digital outputs can have their individual setup.

  • None : When analog or digital line outputs are not used (main loudspeakers only).
  • Lyngdorf presets : For using Lyngdorf woofer models, optimizing their performance with pre-set sound equalizing, crossover, and filters, with the possibility to edit these settings.
  • Advanced : For using the analog or digital line outputs, for example when connecting subwoofers, external amplifiers, headphone amplifiers, recording devices, external DACs or ADCs, or multiroom systems.

The following options can be set

  • Off when the analog output or the digital output is not used.
  • Full range lets the signal pass unfiltered (full frequency bandwidth).
  • Crossover, High Pass Filter removes the frequencies below the set crossover frequency. Crossover, Low Pass Filter removes the frequencies above the set crossover frequency.
  • Tape Out bypasses RoomPerfectTM, Voicings, and volume level regulation.
  • Level lowers the level of this output relative to the main speaker output.
  • Eq allows custom sound equalizing for this output.
  • Mono allows to set the signal to mono for this output.
  • Output level control sets this output to either follow the main speaker’s volume level (Regulated) or to play at full volume level, independent from the main speakers (Full Scale). Warning: Full Scale means
  • maximum output level, which can overload and damage the connected device or speaker.
  • Delay settings allows distance alignment (for example from the listening position to the subwoofer) and taking a signal delay into account (for example DSP latency of an external amplifier or subwoofer).

2nd speaker setup

  • Here you have the option to store a second speaker setup. This will allow you to test another setup or to store and keep two calibrated setups for general use – example: with and without a subwoofer.
  • Enabling this will start the Guided Speaker Setup for the 2nd speaker setup. When complete, the menu item Speaker Setup will be available in the main menu, allowing you to easily switch between the two setups.

Enable limiter

  • Normally increasing the volume setting of any amplifier above the nominal specification will allow for higher levels – just with higher distortion levels. Enabling the limiter will ensure that no matter the overall volume setting, the output stage of the TDAI-3400 will never exceed specified distortion levels.

Routing
The available settings are:

  • Full range allows the signal to pass unfiltered.
  • Crossover will open for other menus for specifying the signal routing

Level

  • Reduce the signal level for this output with up to 24 dB to match the levels of other output channels.

Eq

  • Select any of the built-in equalizer filters or select “Custom” for designing your own filter to optimize the sound from your speakers. See the chapter Voicings, for input as to the design of filters.

Filter

  • Sets the type of crossover filter to be applied to this output
  • High pass : Removes the frequencies below the crossover frequency.
  • Low pass : Removes the frequencies above the crossover frequency.

Filter Type
Sets the type of crossover to be applied to this output

  • LR (Linkwitz Riley): 2nd, 4th or 8th order.
  • BW (Butterworth): 1st, 2nd or 4th order.

The references LR and BW refers to the inventors of these crossover designs. The filter order refers to how steep the filter slopes are. This subject is too complicated to describe in detail in this manual. We refer to external crossover filter literature for further information.

Frequency (Hz)

  • Sets the crossover point for the filter type selected. For traditional setups the frequency should be the same for both Main and Line outputs.

Verify speaker setup

  • This function will send out a signal to each speaker for verifying the wiring against the chosen setup.

Tips for setting up speakers

Stereo triangle
You can use the stereo triangle as a good rule of thumb when determining where to place your speakers. The distance between the speakers should be the same as the distance from your listening position to both speakers.

Tip : You can reduce reflections from the hard floors and hard surface walls by positioning a carpet,painting, a bookshelf, or other furnishings between you and the speakers. These objects act as diffusers.

Find the position of the diffusers by having someone hold a mirror flat against the wall or floor. When you can see the speaker in the mirror from the listening position, you have found the optimal position for the diffuser.

Speaker placement / Traditional box speakers

  • For an optimal listening experience with a RoomPerfect™ calibration, we recommend placing your speakers against the wall, opposite from your preferred listening position.
  • This will ensure the wall reflection and the direct sound will reach your ears at the same time, giving you perfect timing.
  • If your speakers have a bass-reflex port on the back, you should allow for a 5cm/2in clearance to the back wall. This will ensure the bassreflex port will still work as intended.

Subwoofer placement

  • With a single subwoofer, we recommend placing the subwoofer against the wall between the main speakers.
  • With two subwoofers, you should position one in each front corner, in line with the main speakers.

LYNGDORF-TDAI-3400-Tear-Down-The-Living-Room-Was-015

Note : As the Phase, Cut-Off Frequency and Level is now controlled by the TDAI-3400, you should set the controls of connected subwoofer(s) to neutral: Phase: 0. Cut-Off: Maximum. Level: 50% of maximum. When connecting the Lyngdorf boundary woofers, you should connect the analog outputs to the BYPASS input of the woofer.

Measuring distances

  • When measuring the distance to your main speakers, measure from the preferred listening position (the focus position) to the front of the speakers.

LYNGDORF-TDAI-3400-Tear-Down-The-Living-Room-Was-017

  • When measuring the distance to a subwoofer, measure from the preferred listening position to the back corner of the subwoofer.

Note : Always perform a new RoomPerfect™ calibration when you have changed settings in the Output setup.

Introduction to RoomPerfect™

  • It is very difficult to design a perfect listening environment with a symmetrical setup and a perfect reverberation time without vibrating surfaces like windows. A traditional setup of speakers requires uneven distances to back and side walls to avoid having the reflections arrive to the listening position at the same time, as this would have a negative effect to the frequency response. Having strong reflections after each other is though causing smearing of the sound and reduces the overall dynamic performance.

  • RoomPerfect™ is designed to analyze and correct for the negative effects that the listening room has on the speaker sound. Correcting the frequency response only, the setup of speakers should focus on having the optimal dynamic performance by positioning all speakers as close to the back wall as possible – and the sub(s) preferably into the front corners of the room Other correction systems will at their best offer a range of target curves for the calibration, whereas RoomPerfect™ will identify the sound properties of your speakers and use these for the calibration.
    RoomPerfect™ is therefore not just an equalizer, but in fact the only true room correction system.

  • If you want to change the target curve (the tonal balance of your speakers) for the calibration, you can enter your own pre-eq filter design under the Output Setup. Through a new calibration process, RoomPerfect™ will then clean up the new tonal balance.

Global filter

  • The global filter improves sound quality across the whole room. When you are moving around a room, the global filter gives the best result.

Focus position

  • The focus filter improves the sound quality at a specific listening position. This makes the focus filter the best solution for optimal sound quality at a single listening position. A total of 8 focus positions can be stored after the initial calibration.

See our website www.lyngdorf.com for more detailed information.

RoomPerfect™ Setup

The RoomPerfect™ microphone is a very sensitive and finely calibrated device which must be treated with utmost care. If the microphone has been dropped on the floor, it may be damaged. If this is the case, obtain a new microphone from your Lyngdorf Audio representative before performing the system calibration.

RoomPerfect™ Preparations

  • Place the RoomPerfect™ calibration microphone on the stand. Be sure to fasten the screws properly so the microphone does not move during a measurement.
  • Plug the supplied microphone cable into the microphone.
  • Connect the microphone cable to the TDAI-3400 using the included mini-jack connector.

Placing the Microphone in the Focus Position
When you place the microphone in the focus position, connect the microphone to the microphone input on the front of the TDAI-3400 and place the microphone, using the microphone stand, in your primary listening position. The height and the orientation of the microphone should correspond to your head’s height and direction.

Volume Setting

  • Press Enter and a test signal will start from the left speaker. The system will give an estimated optimal volume for calibrating the system or will accept the current volume. Adjust the volume if required by the system and retry the measurement.
  • The calibration volume should not be so loud that it is uncomfortable to you, or that it causes damage to your loudspeakers. If this is the case, set it to a lower and more appropriate level. A low volume can result in a longer calibration time or a measurement timeout. A low volume and long measurement will not affect the quality of the result.
  • If the system continues to require higher signal level, the problem could be a defective adaptor, cable or microphone. Please contact your nearest Lyngdorf Audio representative.

Measuring the Focus Position

  • When the calibration volume has been set, RoomPerfect™ will send a range of pure tones to measure the focus position. If there is noise in the room, the measurement may take longer. This will not affect the quality of the result. See RoomPerfect™ troubleshooting if the measurement stops prematurely, and then retry the measurement.

Measuring Random Room Positions

  • When the focus position has been measured, the next step is to measure the acoustical properties of the room. It is important to perform well spaced measurements to get a comprehensive image of the acoustical properties of the room. See RoomPerfect™ troubleshooting if the measurement stops prematurely.
  • Keep taking measurements until Room Knowledge reaches 90%.

Note : Room Knowledge relates to the level of new information in the last measurement – if there is little new information, the system will translate it to the fact that it knows nearly everything. When the Room Knowledge does NOT increase after a measurement, it means that the measurement gave a lot of new information to the calibration!

These are the rules of thumb when measuring the room

  • The microphone should be in random and varying positions, heights, and orientations. Point it up/down/sideways – the more random positions the better.
  • The measurements should cover the primary listening area.
  • Do not take measurements behind plants, furniture, etc.

LYNGDORF-TDAI-3400-Tear-Down-The-Living-Room-Was-019

Side view of room

  • The microphone should not be closer than 0.5m/1.5ft from the floor, ceiling, and walls.
  • The microphone should be at least 1m/3ft from the front of the loudspeakers.
  • There should be at least 50cm/1.5ft between each measurement.
  • Do not take symmetrical measurements in the room.

LYNGDORF-TDAI-3400-Tear-Down-The-Living-Room-Was-0 20

Top view of room

  • To fully optimize the systems understanding of the room’s acoustical properties, we recommend you keep doing measurements until the Room Knowledge is above 95%. The higher the Room Knowledge, the more accurate the room correction filters will be.

Calculation of Focus and Global Filters

  • When room measurements are complete, the system will calculate the focus and global filters automatically.

Notes

  • Room Knowledge is calculated from the amount of NEW information is in the measurement compared to the data already stored. It is therefore the target to have as SLOW an increase in Room Knowledge as possible.
  • We recommend that you ALWAYS take a backup of TDAI-3400 settings after having performed a RoomPerfect™ calibration (see Manage Software in the Setup section).

Voicing Setup

  • A voicing is an equalizer filter that can be activated to amplify or attenuate certain frequencies according to your personal preferences. For each Source you can dedicate a Voicing, meaning that you can emphasize bass on one input without sacrificing neutrality on others.

Exporting and Importing Voicings

  • It is possible to download single voicings to a file and to add new voicings by uploading those files as well. This will make it possible to copy a voicing from one device to another.
  • The file format is identical for all enabled Lyngdorf products, so if you have a voicing you like on your TDAI-3400 amplifier, it is possible to add that to your Lyngdorf multichannel processor or vice versa.

Note
Single voicing files have the extension single_voicing.xml, and this must not be changed.

  • You can also download and upload an entire set of voicings. Again, these files will work throughout the devices which support this feature.

Note
Uploading a set of voicings with this feature will replace all voicings in the amplifier. Files with an entire set of voicings have the extension .voicings.xml, and this must not be changed.

Edit or delete voicing

  • This dropdown list contains the voicings currently in the amplifier. Selecting a voicing in the list will allow you to delete or edit the selected voicing (this will open the voicing editor)

Add new voicing

  • To create a new voicing using the voicing editor, enter the name of your new voicing and press add.
  • To add a voicing from a .single_voicing.xml file, browse for the file and then Click “Add”.

LYNGDORF-TDAI-3400-Tear-Down-The-Living-Room-Was-0 21

Replace all voicings from file

  • This is the functionality to replace all voicings in the amplifier with a new set from a .voicings.xml file. Remember that this will overwrite all voicings currently in the amplifier. Click “Browse” to find the
    voicings.xml file you wish to upload and then click “Apply” to use it.

  • On the bottom of the page is a link to download the current set of voicings in the amplifier to a .voicings.xml file.

  • Through selecting any of the stored Voicings, you can see the details by selecting “Edit”. You can also delete the stored Voicings and add new ones here.

Creating Voicings

  • A Voicing can combine up to eight filter sections. For each section, you can choose between certain filter designs, which then in combination will give you the total correction of the Voicing.
    For each Voicing you will see a green line showing the total correction as well a blue line showing the correction caused by the selected filter section. If there is only one active filter section, only the blue line is shown. You can select between following filter designs:

  • Low Pass : Functions as a crossover filter reducing the signal above the frequency.

  • High Pass : Functions as a crossover filter reducing the signal below the frequency.

  • Low Shelf : Attenuates the lower frequencies to a specified level.

  • High Shelf : Attenuates the higher frequencies to a specified level.

  • Parametric : Attenuates specific frequency.

  • All these filters can be with positive or negative gain – effectively reversing the effect of the filter.

  • You can adjust the Overall gain for each voicing in order to be able to switch between voicings without experience any change in perceived level.

  • In this example (Action Movie Voicing) you will see the combined effect of two filter sections:

  • Negative High Shelf from 120 Hz –creating a boost in the bass region

  • Negative High Shelf from 8,000 Hz reducing the highest frequencies

  • Overall gain set to +6 dB as compensation for the reduction in overall level experienced with the two filters.

Try experimenting by creating your own Voicings and test the functionality of the different filter sections.

Audio Setup

ICC (Intersample Clipping Correction)

  • ICC can be set to enabled or disabled.
  • Digital audio tracks can exceed 0 dBFS (decibels relative to full scale), meaning they will be clipped when being up sampled or otherwise processed in the audio chain resulting in distortion. With ICC enabled the TDAI-3400 will dynamically allow for extra headroom to avoid clipping during processing the music. Changing inputs or going into standby mode will reset the ICC level.

Hot tip

Default volume

  • The default volume setting controls the default volume at start-up.

HDMI Setup

What is CEC?

  • Consumer Electronics Control (CEC) is an HDMI feature designed to allow you to command and control CEC-enabled devices that are connected through HDMI, by using only one of the remote controls (for example, controlling the volume level in the TDAI-3400 by using the remote control of the TV).
    The level of CEC implementation depends on the manufacturer of each product, and even if brand new, not all electronic devices support CEC. As the television is “CEC master” in a HDMI setup, the CEC implementation of the television will determine, what is possible for the entire system.

Enable CEC

  • Enables and disables CEC (Consumer Electronics Control) over HDMI.

HDMI output

  • When enabled, this feature will send the current digital stereo signal though the HDMI cable to the TV. This feature requires that the digital output has been configured under the Output Setup menu. The digital output should be set to Full-range and Full-scale.

Notes

  • As default, CEC is not activated on HDMI to comply with stand-by power regulations. CEC functionality only works with the TDAI-3400 set in Network Stand-By.
  • CEC is marketed by manufacturers under individual names and designed for promoting the connection of same brand sources. (SONY: Bravia Link, Panasonic: Viera Link, etc.)

Streaming Setup

  • The TDAI-3400 can access radio stations from the internet, music files on your local network or on a FAT32 formatted USB drive or you can stream music to the TDAI-3400 from your mobile devices.

Troubleshooting

Retrieving and Sending an Error Log
To retrieve an error log, you need to access the TDAI-3400 via your browser. Here you can download a System Log and a Backup file. To proceed, please read the section Technical Assistance in this manual.

RoomPerfect™

  • The calibration microphone is very sensitive and may pick up unwanted noise, including subsonic signals and background noise, which disturbs the measurements. If the signal is disturbed, it will take longer for the system to make a correct measurement.
  • A measurement that has been disturbed by noise but completed will always be correct; it is not necessary to redo it. If the measurement has stopped due to an error, one of the error messages below will be shown.

Error Messages

  • No microphone connected
  • No microphone is connected, or the microphone cable is not working. Check that the microphone cable is connected to the microphone socket on the back panel. If the problem continues, test the microphone cable by connecting the microphone directly to the microphone socket and select Retry.
  • If the microphone is detected, replace the microphone cable and retry the measurement.

Fault – No signal

  • This error message can arise due to a signal classification of no sound. This happens if the sound volume has been muted or a cable is disconnected.
  • Check the sound volume.
  • Check all cable connections, including interconnects, speakers, amplifiers, etc.
  • Check the measuring signal volume.
  • If none of these measures solve the error, contact your nearest Lyngdorf Audio representative or Lyngdorf Audio for a replacement microphone.

Fault – Signal clipping

  • Either the incoming signal has been classified as too loud, resulting in clipping or distortion, or a loud noise in the immediate environment has corrupted the measurement results. If a loud noise has in fact occurred, such as the sound of a closing door, reduce noise levels inside and in the immediate vicinity of the room and repeat the measurement. If no loud noise has occurred, reduce the volume of the signal and repeat the measurement.

Fault – Low signal

  • This error message is displayed when the measurement has lasted more than 5 minutes for the low-frequency signal or more than 2 minutes for the high-frequency signal. This happens most often when using
  • a low-level measuring signal compared to the background noise in the listening environment, which results in prolonged measuring times. Raise the measuring signal volume or reduce the noise in the environment before continuing with the measurement.

Can´t Turn On Via LAN or Control System

  • The TDAI-3400 needs to be set to Network Standby to be able to turn on via a control system. It will not turn on when in Deep Sleep. This is controlled in the General Setup menu.

3D/4K/HDR Compatibility Not Detected

  • If the TDAI-3400 has not finished the start-up, a Blu-ray player will not be able to detect its compatibility. Restart the player to fix the problem.
