User Instructions Cyrus Pre vs2
Welcome to the world of Cyrus!
Congratulations on your choice of Cyrus Hi-fi products. Our state-of-the-art
design technology and outstanding quality of manufacture has won countless
awards around the world. We are confident that you will derive great pleasure
from owning a product from one of the most recognised and respected
manufacturers of hi-fi equipment.
Please read these instructions carefully before commencing installation. They
provide full guidance to help you install your Pre vs2 safely and correctly.
Preparations for Installation
Before installing the Pre vs2 check that the following items are included in the
accessory box.
• Warranty Card (with instruction manual)
• Power Cable
• Remote Handset
• 2 MC-Bus cables
After removing these items, please retain the packaging.
Install the Pre vs2 in a well ventilated location away from sources of high
temperature, dust or humidity. Never stand the Pre vs2 under another unit or
on any surface likely to obstruct its cooling or ventilation.

5. MP3 Input 13. Power Inlet
6. Link Input 14. Mains Fuse Holder
7. Aux/PH Input 15. Power Switch
8. AV Input
Connecting to the AC Mains Supply
Connect the socket on the AC Power cable to the Power inlet 1# on the rear panel
of the Pre vs2. Now connect the cable to a suitable AC power point.
The mains power switch 1% on the rear panel of the Pre vs2 should be left on
for normal operation, except when left unattended for a long period when it
should be switched off or disconnected from the AC supply.
Connecting Tape/Disc recorders
To connect the tape recorder you will need two phono cables. Connect one
cable from the Output or Playback sockets of the tape deck to the TAPE Input
d of the Pre vs2 and a second cable from the Input or Record sockets of the
tape deck to the Tape Record Output - TP OUT c sockets of the Pre vs2.
Connecting Headphones
The headphones socket 1@ is a standard 6.35mm (¼") 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.
MC-BUS System (Refer to figs 1 & 6)
Connecting the MC-BUS sockets a of the Pre vs2 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
MC-BUS output of the final component to the MC-BUS input of the first.
With MC-BUS established you can control the power function of the entire
system from the Pre vs2, from the front panel or remote control. Selecting
'CD' from the front panel will switch on the Pre vs2, the Cyrus power amplifier
and a Cyrus CD player. When the Pre vs2 is set to Standby, the entire system
will also switch off.
When a Cyrus Surround Processor is in the MC-BUS loop, setting of the
volume calibration level will take place automatically when Pre vs2’s 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 which will upgrade the sonic
performance of your Pre vs2. When a Pre vs2 / PSX-R combination is
installed, analogue and signal related sections of the Pre vs2 are powered
from this clean, stable power source 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.
To connect the PSX-R to the Pre vs2 plug the connector on the umbilical cord
of the PSX-R into the Multi-Pole socket on the rear of the Pre vs2 (1! Fig.1)
You will need a mains supply for both units.
Connecting a Power Amplifier
Connect a phono cable from the Pre-amplifier Output sockets b to the input
of your power amplifier.
Connecting Signal Inputs
Connect a phono cable between each component and the sockets as marked
on the rear panel. Ensure left and right channels are correctly connected. The
Pre vs2 has inputs for CD Player - CD
decoder - AV h and three auxiliary inputs – AUX/PH g, LINK f and MP3 e
which can be used to connect a wide variety of products. Check the
specification of these products before connecting to your Pre vs2.
1), a tuner - TU i, a Home Theatre
Connecting a Turntable
The Pre vs2 is a line level amplifier. To play a turntable through your unit an
external phono pre-amplifier is required.

Power
When power is applied, the STANDBY key b is used for power control. The
Standby light c shows green when the Pre vs2 is operating and glows red
when in standby mode. The Pre vs2 will switch from standby to on, when any
input key h-1# is selected.
In regular use the Pre vs2 should be connected permanently to the mains
power supply. When left unattended for a long period (vacations etc) it should
be disconnected from the AC supply.
When the Pre vs2 is switched to Standby, all settings for input selection and
Volume/Balance are retained.
Selecting an Input
The INPUT SELECT keys h-1# switch selected input sources. When an input
key is selected, the red indicator above the key will turn on.
Tape/Disc Playback and Recording
Playback: You can play back a recording by selecting the appropriate key
TAPE g. When TAPE is selected the indicator above the selected key will
light in addition to the selected source. To cancel TAPE, press the TAPE key
again. If the tape recorder has a three-head facility, selecting the TAPE key
will monitor the recording directly from the third head, whilst recording.
Recording: To record, select an input to record with the relevant Key h-s
and follow the recording instructions in your tape deck manual.
Programmable Input Sensitivity (Refer to fig 4)
You may find an audible difference in level when switching from one input to
another due to the differing outputs of your source components. The unique
calibration memory of the Pre vs2 can be programmed to match the sensitivity
of all inputs with reference to the CD input. To program an offset:
1. Select CD input and set the volume control to a comfortable listening
level.
2. Select the desired input and hold the input key down. The volume
display switches to show input offset.
3. Adjust the level to the same audible volume as the CD player. The
display will read the offset applied.
4. Press the input key again to store this setting.
Repeat Steps 2 - 4 for each input to set the appropriate sensitivity level.
Fig. 4 shows settings for Input Sensitivity levels set -2 dB, 0dB and +2dB
relative to the CD input respectively.
Volume and Balance (Refer to fig 3)
The LEVEL CONTROL f of the Pre vs2 performs the dual functions of
volume and balance.
Volume: In normal mode the LEVEL CONTROL controls the volume in 1dB
steps. The light ring around the knob is calibrated to show the current
loudness level. When the volume is at minimum the first indicator on the light
ring will be RED. As the volume increases a GREEN light moves clockwise
around the ring. The volume setting is stored when the unit is set to standby.
Press the MODE control key on the remote control to change the
Balance:
mode of the front panel LEVEL CONTROL f to that of Left/Right Balance.
The light ring works in "reverse video" with the unlit section indicating the
position of L-R balance. You can alter L-R balance by up to +/-4dB or switch
one channel off when the control is turned to an extreme.
Mute
Pressing the MUTE Key a will fade the volume to minimum level without
disturbing the existing setting. When muted the RED minimum level indicator
will light as well as the existing GREEN light to show that the output is muted.
Move the volume knob up or press the Mute key to fade back up to the
original volume setting.
Listening to headphones
To listen to headphones, press the PHONES key d. The MUTE light at the
bottom of the light ring will now glow orange. The speakers will now be muted
for headphone listening. Press the PHONES key
loudspeaker operation.
NOTE: The PHONES key d only operates when headphones are connected
to the rear panel socket of the Pre vs2.
Caution: If you have been listening to headphones at high volume, be sure to
turn the level down before you switch to normal loudspeaker operation.
