Cyrus Phono Signature User Instructions

Important – read before making any audio
connections
To avoid possible damage to your preamplifier, it is essential
to disconnect all system components from the mains supply
before connecting or disconnecting audio interconnects.
Connecting Turntables
Turntables may be connected to any of the four available
inputs e - h as each input is separately programmable for
use with moving coil or moving magnet cartridges.
Connect the left and right plugs from the turntable audio •
cable to the left (white) and right (red) connectors of the
input you are using.
Connect the ground wire from the turntable to the •
corresponding ground terminal.
Setting the ground lift switch
The chassis of the Phono Signature is connected to mains
ground. The Ground Lift switch
d
enables the circuit of the
Phono Signature to be linked to mains ground or isolated.
The setting of this will be system dependent.
The factory setting for the switch is to the ‘LIFT’ position.
If any hum or buzz noises are apparent when playing a
turntable, setting the switch to the ‘GND’ (grounded)
position may cure the problem.
If hum or noise problems persist when playing a turntable
and the switch setting does not cure the problem, contact
your retailer to check the ground connection arrangements
on your turntable and other system components.
Connecting the output
There is a choice of balanced (XLR) or unbalanced (phono)
outputs to connect to your system preamplifier/amplifier.
NOTe: The Phono Signature does not include a volume
control so it is not suitable for direct connection to a power
amplifier. It must be connected to an amplifier that includes
a volume control.
Connecting balanced XLR outputs
The XLR outputs
c
are compatible with balanced audio
inputs on a preamplifier.
Connect left and right XLR cables between the left •
and right XLR outputs of the Phono Signature and the
corresponding inputs of the preamplifier.
Connecting unbalanced phono outputs
The phono outputs
b
are compatible with unbalanced audio
inputs on a preamplifier.
Connect a dual phono cable between the left and •
right phono outputs of the Phono Signature and the
corresponding inputs of the preamplifier.
MC-BUS system connection (Optional)
By using the MC-BUS connection
a
on your Phono Signature ,
a highly functional integrated system with full remote
control may be set up. This feature is usable if you own a
Cyrus amplifier. Refer to the relevant product handbook for
MC-BUS wiring instructions.
External power supply - PSX-R/PSX-R
2
The PSX-R is a unique dC power supply that will upgrade
the sonic performance of compatible products in the Cyrus
range. The PSX-R
2
is a performance upgraded version of
the PSX-R . Both of these power supplies are compatible for
connection to the Phono Signature
.
The following text refers to the use of the PSX-R , but applies
also to the PSX-R
2
.
To connect a
PSX-R
, disconnect both components from the
mains, then plug the connector on the umbilical cord of the
PSX-R
into the Multi-Pole 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
1!
on the rear 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.
