Connecting to power, loudspeakers and
other equipment
Follow the installation instructions for the integrated amplier on
pages 4 and 5.
AUDIO IN – Connect this input to the output sockets of your pre-
amplier or the PRE OUT sockets of an integrated amplier.
MONO LINK – The power amplier can be adapted to provide
two mono loudspeaker outputs from a single input. Pull out
the link supplied and use it to connect the L and R AUDIO OUT
sockets together. Using one power amplier per loudspeaker
will enable you to bi-amplify bi-wireable loudspeakers.
This is particularly benecial for top quality stereo installations
with a separate pre-amplier, or where ampliers are provided
for the left, centre and right channel loudspeakers in a ve
speaker Dolby Pro Logic or Dolby Digital system.
Contact your Arcam dealer for more information.
“Daisy chaining” – The power amplier can be connected to
further power ampliers to drive more speakers (e.g. those in
other rooms or tri-amplied speakers, etc).
Connect the extra power amplier inputs to the AUDIO OUT
sockets on the power amplier, left to left, right to right.
Installation: P90 power amplifer
Remote switching
By making a connection from the REMOTE IN socket of the P90
power amplier to the TRIG OUT socket of the A90 integrated
amplier, you can use the A90 to switch the power amplier on
and off. If congured in this way, the front panel POWER button
of the A90 (or the POWER/STANDBY button on the remote
control) switches both ampliers on and off together. This facility
allows you to conceal the power amplier yet still control it.
The connecting cable required is a 3.5mm to 3.5mm jack lead
(stereo or mono) and it is possible to connect several power
ampliers to an A90 by ‘daisy chaining’ from TRIG OUT of one
P90 into the REMOTE IN of the next.
Three channel option
The power amplier can be upgraded from stereo to three
channels by adding a Third Channel Module: in this case, the
model is designated P90/3.
The module offers extra loudspeaker terminals together with a
third set of AUDIO IN and OUT phono sockets and converts the
P90 into a 3 x 90W (RMS per channel into 8Ω) amplier suitable
for Home Cinema or multi-channel audio use.
Contact your Arcam dealer for further details.
