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 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

which can be used to connect a wide variety of products. Check the
specification of these products before connecting to your Pre vs2.
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.
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.
