Connecting to the AC Mains Supply
Connect the socket on the AC Power cable to the Power
inlet c on the rear panel of the PSX-R2. 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 mes.
Connecting the PSX-R2to Cyrus Products
Only one connecon is necessary from the PSX-R2power
supply to a Cyrus product. The 5 pin connector d ed
to the umbilical cable must be securely connected to the
socket marked PSX-R on the rear of the partnering Cyrus
product. When correctly ed, the connector will latch into
place in the socket. Note that when a PSX-R2 is in use, both
the PSX-R2power supply and the Cyrus product will require
connecon to the mains supply.
Use with early Cyrus products
When used with a Cyrus III, Cyrus IIIi, Cyrus 7 or Cyrus
Power, the amplier must be internally changed to accept
this external power supply. This modicaon should only be
carried out by an appointed Cyrus Dealer. If you decide to
use a modied component without a Cyrus PSX-R2, the unit
must be re-congured.

OPERATION
Key to the front panel drawing
Power
The mains power switch a is located on the rear panel of
the power supply. This switch should be le on for normal
use, except when le unaended for a long period. In this
case the mains power should be switched o or the product
disconnected from the AC supply.
In normal use, standby operaon of the PSX-R2is controlled
by the partnering Cyrus component. When correctly
installed, the Standby lights on the front panels of the two
products work in unison.
Additional information
Your power supply incorporates electronic protecon to
ensure reliable, long term use. The PSX-R2is designed
to adjust its output DC voltage to that required by the
partnering Cyrus product.
Two levels of regulaon exist in the PSX-R2circuitry in order
to give maximum isolaon from mains borne disturbances
and the voltage ripple due to the charging of the supply
reservoir capacitors, this design has also enhanced the load-
regulaon of the PSX-R2.
