Important – read before making any audio connections 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.
Connecting a power amplifier/speakers Unbalanced connection • Connect a phono interconnect from the ‘PRE OUT’ sockets to the unbalanced inputs of the power amplifier. Ensure left and right channels are correctly connected. The Classic PRE requires an external power amplifier to drive the system loudspeakers. The Classic PRE can also be connected to active speakers which have built-in amplifiers. Two types of output connection are provided - balanced via XLR connectors and unbalanced via phono connectors.
Connecting a power amplifier/speakers Bi-amping The pre-amplifier output may be used in conjunction with additional power amplifier(s) to significantly upgrade your loudspeaker system through Bi-amping. The Cyrus range of power amplifiers is recommended for this application as they will have the correct matching gain. Both stereo and high power monobloc Cyrus power amplifiers are available to partner your Classic PRE.
Using the fixed output of your preamplifier Connecting a Cyrus surround sound decoder 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. If your system includes a Cyrus multi-channel surround sound decoder, it may be connected through your stereo preamplifier to share the main front speakers of your system.
MC-BUS System External power supply - PSX-R Connecting the MC-BUS sockets in an MC-BUS system provides unified system control. 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 PRE. 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 daisychain.

Remote control operation Sending commands to Cyrus components Remote control introduction The iR14 remote control will send commands to Cyrus amplifiers, CD players, Audio streamers* and the Phono Signature. The remote control can also be programmed with the commands from two other remote control handsets. These will normally be for your TV and a Satellite or terrestrial TV set-top box, programmed to the TV and SAT buttons, but could also be other audio components such as a Cyrus tuner or DVD player etc.
Cyrus amplifier commands • Press the CYRUS key to set the remote control to Cyrus mode. You can now control the Cyrus amplifier. The CYRUS key will flash red when commands are being sent in Amplifier mode. The Amplifier mode commands available are listed below – 1. Set Cyrus amplifiers, CD players and Audio streamers to Standby. 2. Set the handset to send commands to Cyrus components. 3. Send commands to a Satellite receiver (or other device programmed to use this key). 4.
Cyrus CD player commands • Press the CYRUS key • Press the key to set the remote control to CD mode. The key will light red. You can now control both a Cyrus CD player and amplifier. The key will flash red when commands are being sent in CD mode. The CD mode commands available are listed below – 1. Set Cyrus amplifiers, CD players and Audio streamers to Standby. 2. Set the handset to send commands to an amplifier. 3. Send commands to a Satellite receiver (or other device programmed to use this key). 4.
Cyrus audio streamer commands • Press the CYRUS key • Press the key to set the remote control to Audio streamer mode. The key will light red. You can now control both a Cyrus Audio streamer and amplifier or an Audio streamer that includes an amplifier. The key will flash red when commands are being sent in Audio streamer mode.

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.
Factory settings Firmware updates You can restore the configuration of your preamplifier 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 preamplifier. Hold down the setup key on the front panel and re-connect the power cord.
1 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. 3. Press and hold the SETUP key.
Checking programmed commands Sending TV or SAT 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.
Troubleshooting guide Error indicators Your preamplifier has a unique error indication system to help you to diagnose problems. There are two error condition messages that may be displayed in the event of a system error – If your preamplifier is not operating properly, disconnect the power and check carefully all connections. If you are in any doubt, consult your retailer.
