Bi-amping
The twin pre-amplier outputs may be used in conjuncon
with added power amplier(s) to signicantly upgrade your
loudspeaker system through Bi-amping. The Cyrus range of
power ampliers is recommended for this applicaon.
NOTE: A bi-amp system can only be set up with speakers
that have bi-wire connecons (separate bass and treble
connecons).
Connecng power ampliers
Two power ampliers will be required to partner a Cyrus
Pre
2
DAC pre-amplier in a bi-amplied system.
Both stereo and high power monobloc Cyrus power
ampliers are available to partner your amplier.
Connecng a Cyrus Surround Sound decoder
If your system includes a Cyrus mul-channel surround
sound decoder, it may be connected through your stereo
amplier to share the main front speakers of your system.
In this case, connect a stereo phono interconnect from the
front channel outputs of the surround decoder to one of the
Analogue Inputs of the amplier. For this system to funcon
correctly both the amplier and the Cyrus surround decoder
must be included in an MC-BUS connecon loop and the
‘Cyrus AV’ input name must be set for the input used (see
‘MC-BUS’ secon and ‘Input names’ in the ‘Setup menu’
secon).
When set up in this way, the amplier will automacally
check for the presence of the decoder when the ‘Cyrus
AV’ input is selected, then lock its volume seng to an
appropriate level.
Connecng a Surround Sound decoder (other
brand)
If your system includes a mul-channel surround sound
decoder (but not a Cyrus model), it may be connected
through your amplier to drive the front channel speakers.
In this case, connect a stereo phono interconnect from the
front channel outputs of the surround decoder to one of the
Analogue Inputs of the amplier. For this system to funcon
correctly, the ‘AV Direct’ input name must be set for the
input used (see ‘Input names’ in the ‘Setup menu’ secon).
When set up in this way, the amplier will automacally lock
its volume seng to a xed level to match the output of the
surround decoder.
CAUTION: The ‘AV Direct’ input name should only be used
for surround decoders that include a volume control, as the
volume control of your amplier will be xed at a very high
level.
NOTE:- Refer to the wiring plan of a bi-amplied system.
Take care to connect each of the amplier output channels
to the correct power amplier and loudspeaker.
Connecng Headphones
The headphones socket 1& is a standard 3.5mm stereo jack
socket for connecon to a pair of headphones. Headphones
may be permanently connected to the amplier and selected
when required with the front panel switch.
