Important – read before making any audio connections

To avoid possible damage to your amplifier, it is essential to disconnect all system components from the mains supply before connecting or disconnecting audio interconnects.

Connecting analogue audio sources

• Connect a stereo audio interconnect cable between each analogue source component and one of the analogue input sockets ‘AN1 – AN4’.
  Ensure left and right channels are correctly connected.
  Make a note of the input number used for each source as the inputs can be re- named at the set-up stage.
  The analogue inputs are compatible with the connection of stereo analogue audio sources. These include Analogue output from CD/Blu-ray Players Analogue output from DAB or FM radio tuners Analogue output from a TV  Analogue tape recorders Surround decoders

Connecting a turntable

The PHONO/MM input is compatible with turntables fitted with moving-magnet cartridges (for moving coil cartridges an external phono stage will be required, connected to an analogue input). The turntable will have a cable with two plugs, and often a thin ground wire with a tag

• Connect the plugs to the ‘PHONO/MM’ sockets on the back panel. Connect the white plug to the left socket and the red plug to the right socket.
• Unscrew the ‘GROUND’ terminal then fasten the ground wire (where fitted) under the terminal.

Connecting digital audio sources

• Using a suitable Toslink optical or digital phono interconnect, connect each digital audio source to one of the inputs ‘DIG1 – DIG4’.
  Make a note of the input number used for each source as the
  inputs can be re-named at the set-up stage.
  The digital audio inputs are compatible with a number of
  different digital audio sources. These includeDigital audio output from a CD player
  Digital audio output from a TV
  Digital audio output from a games console
  Digital radio
  Blu-ray players
  Digital satellite receivers
  Digital tape/disc recorders
  NOTE: The digital audio inputs are only compatible with 2
  channel PCM source material and will not reproduce multichannel surround sound.

Connecting loudspeakers

The Classic AMP is supplied with a pair of dual speaker plugs. To ensure safe operation of this amplifier, the speaker cables must be terminated with the supplied speaker plugs, assembled in accordance with the instruction supplied with the plugs.
Never terminate the cables with separate 4mm/banana plugs.
NOTE: Additional plug kits are available from Cyrus if required.

• Following the instructions supplied with the speaker plugs, assemble the plugs to the speaker cables.

Observe polarity. The + and – speaker terminals of the amplifier must be connected to the corresponding + and – terminals of the speakers. To identify polarity at each end of the cable, most cables have polarity indicators. This is usually a stripe or a rib on one conductor as shown in the examples below. The polarity marking indicates the + cable.

Your cables may also be marked for directionality with arrows. In this case, the arrows should always point in the direction of signal flow towards the speakers.

• Once the plugs are fitted to the cables, Plug each cable into the speaker sockets on the back panel and into the speaker.

Using the fixed output of your amplifier

The fixed output will feed the sound of the source currently playing at full volume to a tape recorder, a second amplifier in another room or a pair of active speakers with built-in amplifier(s) and volume control.
Connecting a tape recorder for recording

• Using a stereo phono interconnect, connect from ‘Fixed Out’ to the line input or record input of a tape/disc recorder.

You can now record the source you are playing on the tape/ disc recorder.
Connecting a second amplifier
NOTE: Ensure that the second amplifier includes a volume control.

• Using a stereo phono interconnect, connect ‘Fixed Out’ to an analogue input of a second amplifier feeding speakers in another room.

You can now play the same music in both rooms and use the volume controls on the two amplifiers to control the volume in each room separately.

Connecting headphones

The headphones socket is a standard 3.5mm stereo jack socket for connection to a pair of headphones. Headphones may be permanently connected to the amplifier and selected when required with the front panel switch.

Connecting a Cyrus surround sound decoder

If your system includes a Cyrus multi-channel surround sound decoder, it may be connected through your stereo amplifier to share the main front speakers of your system.

• In this case, connect a stereo phono interconnect from the front channel outputs of the surround decoder to one of the analogue Inputs of the amplifier.
  For this system to function correctly both the amplifier and the Cyrus surround decoder must be included in an MC-BUS connection loop and the ‘Cyrus AV’ input name must be set for the input used (see ‘MC-BUS’ section and ‘Input names’ in the ‘Setup menu’ section).

When set up in this way, the amplifier will automatically check for the presence of the decoder when the ‘Cyrus AV’ input is selected, then lock its volume setting to an appropriate level.

Connecting a surround sound decoder (other brand)

If your system includes a multi-channel surround sound decoder (but not a Cyrus model), it may be connected through your amplifier to drive the front channel speakers.

• In this case, connect a stereo phono interconnect from the front channel outputs of the surround decoder to one of the analogue Inputs of the amplifier.
  For this system to function correctly, the ‘AV Direct’ input name must be set for the input used (see ‘Input names’ in the ‘Setup menu’ section).

When set up in this way, the amplifier will automatically lock its volume setting to a fixed level to match the output of the surround decoder.
CAUTION: The ‘AV Direct’ input name should only be used for surround decoders that include a volume control, as the volume control of your amplifier will be fixed at a very high level.

MC-BUS System

Connecting the MC-BUS sockets in an MC-BUS system provides unified system control An MC-BUS loop is established by connecting single phono cables from the MC-BUS output of one unit to the MC-BUS input of another in a daisy chain. Complete the loop by returning the MCBUS output of the final component to the MC-BUS input of the first.

With MC-BUS connection established you can control the power function of the entire system from the front panel or remote control. Selecting ‘CD’ from the front panel will switch on the amplifier, the Cyrus power amplifier and a Cyrus CD player. When the amplifier is set to Standby, the entire system will also switch off.
When a Cyrus Surround Processor is included in the MC-BUS loop, setting of the volume calibration level will take place automatically when the ‘Cyrus AV’ input is selected. Refer to the handbook for the Surround Processor for further details.

External power supply – PSX-R

The PSX-R is a unique DC power supply that will upgrade the sonic performance of compatible products in the Cyrus range including the Classic AMP.

Connecting a PSX-R

• Disconnect both components from the mains.
• Plug the connector on the umbilical cord of the PSX-R into the Multi-Pole PSX-R socket on the back panel. You will need a mains supply for both units.

NOTE: Connection of a PSX-R is detected automatically, so no internal adjustments are required.
How it works
When a PSX-R is connected to a Cyrus product, the power feeds to the internal circuitry are split two ways with the clean, stable power source of the PSX-R feeding sensitive circuit sections while other requirements are supplied internally. This ensures complete isolation of control circuits and sensitive analogue sections reducing AC mains-borne noise and power supply ripple.

Connecting to the AC mains supply

• Connect the socket on the AC Power cable to the power inlet on the back panel of the amplifier.
• Now connect the cable to a suitable AC power point.

NOTE: The means to disconnect this product from the mains supply is the mains plug. Ensure that the mains plug is accessible at all times.

The factory default setting – ‘small input’ display will also identify the sample rate of the selected source (digital inputs only) and indicate ‘Invalid Audio Format’ for program material which cannot be decoded (such as multi-channel digital sound from DVD players).

Selecting the ‘Cyrus AV’ or ‘AV Direct’ inputs

The ‘Cyrus AV’ and ‘AV Direct’ input names are reserved only for use with surround-sound decoders. When one of these inputs is selected, the volume control on the amplifier will lock and the surround decoder input select and volume controls are used to select a multi-channel source and set the volume level for the system.
To unlock the volume control and return to playing a stereo source, select the input you want to play at the amplifier.

Volume and balance

The level control performs the dual functions of volume and balance.
Volume

• Turn the level control to set the volume in 1dB steps. The volume level is shown by a bar graph and numerically in dB at the right side of the display

Safe volume levels after standby
The last used volume level setting is stored when the unit is set to standby. If the volume setting is set to an abnormally high level (greater than –30dB) before entering standby, the level will be reduced automatically to a safer level of –30dB for next use.

The default input names are AN1-AN4 (for analogue inputs), PHONO (for the phono input) and DIG1-DIG4 for the digital inputs. The name of any input may be changed from the default to a choice from the name list. Each name may be used once.
The name list is –
Default name, No Source, CD, DAB, Cyrus AV, Tape, Satellite, Cable, iPod, MP3, DVD, DVD1, Blu-ray, CD 1, CD 2, SACD, CD-R, Linkserver, Jukebox, LaserDisc, Tuner, AV Direct, TV, TV 1, AV, Satellite 1, Cable 1, Video, VCR, PVR, Cassette, DAT, MiniDisc, Games, Games 1, PC, Laptop, Mac, Special, Keyboard, Aux, Stream X.
The PHONO input is an exception and may only be named PHONO or removed from the source list (select No Source) in which case the PHONO name can be re- assigned to another input. This may be necessary when an external phono preamplifier is in use.
Before changing the names of the inputs, we recommend making a list of each input number with your preferred name from the choices above before setting the names. Each name may only be used once. When a name is assigned to an input it will be removed from the list for other inputs.
Choose ‘No source’ from the list to name inputs which have no source connected to them. When named ‘No Source’, an input number will not appear in the input selector sequence. NOTE:- There are two special function input names marked **. ‘Cyrus AV’ is reserved for the connection of Cyrus surround sound decoders to one of the analogue Inputs 1-6 and should only be used for this purpose.
‘AV Direct’ is reserved for the connection of non-Cyrus surround decoders to an analogue input. This input name must only be used for this purpose as the volume level will lock to a very high setting (-6dB) when AV Direct is selected.

Display mode

There are three modes of display operation.

The ‘small input’ setting will show a three line display with the volume reading at the top of the display, the selected input in the display centre and the current sample rate/lock status at the bottom when a digital input is selected.

The ‘large input’ setting will show a two line display with the volume reading at the top and a larger input legend below.

The ‘large volume’ setting will display large volume characters at the bottom of the screen with the bargraph above.

I **nput sensitivity offset

** It is possible to adjust the relative sensitivity of individual inputs by selecting the appropriate trim option from the menu. This enables the volume level to be  equalized between system sources when playing low or high output source components such as tape decks or tuners.

Factory settings

You can restore the configuration of your amplifier to the factory original settings, changing the input names to those listed above, setting the display mode to ‘small input names’, setting all input sensitivity trim settings to 0dB and enabling Auto-Standby.
To restore the settings, first disconnect the power cord from the amplifier. Hold down the setup key on the front panel and re-connect the power cord.

Firmware updates

The operational firmware may be upgraded from time totime to add new features and to fix operational issues. New firmware versions will be available from the ‘Support’ pages of the Cyrus website www.cyrusaudio.com. If new firmware is available, this will be packaged with other documents including –

• Firmware version change log.
• Latest firmware update procedure.
• Revised handbook (if required).

Remote control learning

In addition to controlling Cyrus components, the remote control can learn the commands from two other remote control handsets. These will normally be a TV and a Satellite or terrestrial TV set-top box, programmed to the TV and SAT buttons, but could also be other audio components including a Cyrus tuner or DVD player etc.
All keys may be programmed with the exception of the groups marked CONTROL and SOURCE and the SETUP key.

Preparation for learning

Check the following points before attempting to learn any commands –

• Check that both remote controls have fresh batteries.
• Choose a location on a tabletop that is not brightly lit. Subdued light is better, away from bright natural or indoor lighting.
• Check that you have enough time to spare to complete the learning process for all the keys you want to use

Learning commands

In this example, the Cyrus remote control will be learning commands from a ‘reference’ Satellite receiver remote control.

1. Set the two remote controls up facing each other, spaced by about 5cm.

2. Press the TV or SAT key to select the mode that you want to program.
   The keypad will light and the key you selected will be red.

3. Press and hold the SETUP key.

the mode key will change to white. After about three seconds, the mode key will light red again. This indicates that the remote control is ready to learn codes.

4. Release the SETUP key.
   The remote control is now waiting to learn commands. The keypad will light continually and the mode key will light pale red.

5. On the reference remote control, press and hold the first key you want to learn (for example, volume up) until the mode key flashes red.
   This indicates that the command has been received.

6. Release the key on the reference remote control.

7. Press a key on the Cyrus remote control (volume up in this example) to select where you want to save that command.
   The mode key will stop flashing. This indicates that the command has been saved successfully.
   If the learning process was successful, the remote control will be ready to learn the next command.

8. Repeat steps 5 to 7 for each command you want to learn. When you have completed learning all commands –

Press the SETUP key.
The mode key will change to white. After a few seconds the backlight will switch of

Checking programmed commands

• Select the mode that you just programmed and check that the commands were learned successfully.
  NOTE: The TV or SAT mode key should flash red when sending a command. If the mode key is not flashing, then the command has not learned correctly.

• Make a note of any commands that have not programmed correctly and repeat the learning process to add these in.

NOTE: When you start the learning process it does not erase any programmed keys so you can re-program individual keys if required.

Problems with learning

If none of the commands have learned correctly, try restarting the learning process again. Test a few keys first to ensure that your handset is compatible for learning. If the test works then continue to program the rest of the commands you need.
If you still have problems, check carefully that the mode light is flashing correctly as you send a command to learn. If not, it may be that the batteries need replacement in the reference handset or that the spacing between the handsets is not ideal. Try adjusting the spacing between the handsets and repeating the learning process.
If you continue to have problems, it may be that your handset is incompatible with the learning process. This could happen with an older design of handset or one that has an unusual code-set.

Sending TV or SAT commands

Once you have programmed all the keys with the commands you want, you can use the remote control to send commands to your TV or Satellite receiver etc.

• Press the TV or SAT key to select the mode you want.
• Press the command key.

The mode key will flash red when sending a programmed command.

Troubleshooting guide

If your amplifier is not operating properly, disconnect the power and check carefully all connections. If you are in any doubt, consult your retailer.

No sound

The amplifier is switched off or in Standby| Bring the unit out of Standby (Standby light – GREEN)
Mute is on| Deselect Mute
The source is not working (e.g. CD not playing or paused)| Check the source
No sound (digital sources)
The sample rate or sound format of the digital signal from the source may not be correct.| Check that the sample rate from the source is within the specification of the amplifier and that the program is encoded as two channel stereo.
No sound from one loudspeaker
BAL control at extreme limit| Centralize Balance
Does your speaker have fuses?| Check speaker, replace fuses
Speaker cables / interconnects faulty| Check connections, cables – replace if needed
Spurious noises from speakers
Interconnects or connections faulty| Check, replace where necessary
Remote control not working
Remote control not operating| Check batteries
Remote control lights flash| This indicates that the batteries are flat

Error indicators

Your amplifier has a unique error indication system to help you to diagnose problems. There are four error condition messages that may be displayed in the event of a system error –

Error – Temperature

The amplifier has over- heated. This may occur if the amplifier is driving low impedance speakers, if the volume is set too high for prolonged listening, or if there is inadequate ventilation for the amplifier.| The amplifier will lock in standby until it has cooled down. If this happens regularly, try improving the ventilation around the casing of the amplifier. If the problem continues, then the impedance rating of your speakers may be too low.
Error – Output
The amplifier output has been overloaded. This is usually due to a short- circuit at the loudspeaker terminals.| Switch off the amplifier and check that there are no short circuits in the speaker wiring at the amplifier rear panel or at the speaker terminals.
Error – PSU
This error will be displayed if there is a fault with the internal power supply of the amplifier.| A PSU error cannot be corrected by the user.

The amplifier should be returned to your retailer.

Error – Mains
This error will occur if there’s a significant disturbance in the mains power supply.| Switch off mains power, wait for 30 seconds and re-connect power. The error should not re-occur if the mains power supply is stable.
