Cyrus Power - Stereo and Monobloc Wiring

INSTALLATION Cyrus Power Amplifier
English
6
STEREO AND DUAL MBLOC MODES
The Cyrus Power can be configured as either a stereo
50W per channel amplifier or as a single channel 100W
Mbloc mono amplifier. In Mbloc mode not only is there
an increased power advantage but also complete left and
right channel separation. The Cyrus Power is factory set
for stereo operation.
Note:
In Mbloc mode a Cyrus PSX-R regulated power
supply is required for each amplifier, in Stereo mode the
PSX-R is an optional upgrade. Before connecting a PSX-R
power supply to the Cyrus Power, be sure to have your
amplifier converted by your dealer or an authorised Cyrus
service organisation.
Caution:
When the Cyrus Power is installed for Mbloc
operation, connect the loudspeaker cable to the -MBLOC
1
and +MBLOC
10
speaker terminals. Loudspeaker
switch boxes and other equipment should not be
connected to the output of the Cyrus Power in Mbloc
mode.
Refer now to the following section if the Cyrus Power is
to be used in a Stereo installation or to page 8 for Mbloc
system connections.
Note:
Ensure all equipment is turned off before any
connections or disconnection's are made.
CONNECTION FOR STEREO SYSTEMS
Stereo Input connection options
Both RCA and balanced input connectors are available to
link the Cyrus Power to a Preamplifier. Recommended
connection options are shown to follow-
1. Bi-amplification with a Cyrus III- use a quality RCA
phono interconnect.
2. Installed next to a Cyrus Pre Preamplifier- use a
quality RCA phono interconnect.
3. Installed with a Cyrus Pre Preamplifier, but placed
next to the speakers- Use Balanced XLR interconnects.
4. Power amplifier for a Cyrus AV system- use a quality
RCA phono interconnect.
Note: In a system which supports both connection options
(such as Cyrus Pre/Cyrus Power), the above are
recommendations only and the final choice is made at
the discretion of the user.
