Placement
When installing Mono X Signature amplifiers, choose a position where
there is at least 3cm clearance from the sides and top of the amplifier
to allow cooling air to circulate. Never stand the amplifier on a soft or
carpeted surface or install the amplifier in an enclosed space or cabinet
where cool air cannot enter.
Connecting to the AC Mains Supply
Connect the socket on the AC Power cable to the Power inlet
h
on the
rear panel of the Mono X Signature. Now connect the cable to a suitable
AC power point.
The mains plug is the disconnect device for this product. Ensure that the
mains plug is always readily accessible.
Identifying System Channels
Each Mono X Signature drives a single speaker. In a stereo system two
Mono X Signatures are necessary, in an AV system, a Mono X Signature
amplifier will be necessary for each channel. Before proceeding to connect
your amplifiers, take some time to organise your system so that you can
easily identify which amplifier will be connected to each speaker.
Connecting a Pre-Amplifier or Surround decoder
Phono (RCA)
e
and Balanced input connectors
d
are available to link the
Mono X Signature to a pre-amplifier or surround decoder.
If your amplifiers are a long distance from the pre-amplifier/decoder,
or beside a loudspeaker, then balanced XLR connections
d
may give
improved performance.
Input Connection via phono (RCA) interconnects
Connect a single phono interconnect from the phono input e of each Mono
X Signature to the corresponding output of the pre-amplifier/decoder.
In the system illustration on this page, a Cyrus preamplifier is connected to
two Mono X Signature amplifiers, one for the left channel and one for the
right channel. Input connections are shown using phono interconnects.
Input Connection using Balanced XlR cables
Connect a 3-pin XLR cable from the balanced input
d
of each Mono X
Signature to the corresponding XLR output of the pre-amplifier/decoder.
Connecting loudspeakers
CAuTION: Choice of speaker cables
When choosing speaker cables, avoid litz-wound cables with a complex
‘plaited wire’ construction. These cables can be highly reactive and may
degrade the sound of your amplifier. Always choose a cable of simple
construction, manufactured from high quality materials and priced
sensibly within the cabling budget of your system.
If in doubt about the correct cable to choose, any Cyrus retailer will be
able to advise.
fitting the loudspeaker plugs
Check for polarity indicators (+ and -) on the loudspeaker cable and fit
the plugs provided. Observe any signal directionality markings indicated
on the cable. If an arrow is printed on the cable it should point toward
the speaker.
If additional or replacement loudspeaker plugs are required for the Mono
X Signature, ensure that the correct ‘BFA’ type are purchased.
Connecting the cables
After checking all the assembled cables for polarity they can be plugged
into the loudspeakers and amplifiers. The ‘+’ and ‘-’ terminals of each
loudspeaker must be connected to the matching ‘+’ and ‘-’ terminals of
each amplifier as follows-
Connect the left loudspeaker to the rear panel sockets
a
(red speaker
plug) and
b
(black speaker plug) of the left channel Mono X Signature.
Connect the right loudspeaker to the rear panel sockets
a
(red speaker
plug) and
b
(black speaker plug) of the right channel Mono X Signature.
Dual outputs are provided for the convenient connection of bi-wiring
speaker cables. The diagram below shows a wiring schematic for a bi-
wired stereo system.
