two mono loudspeaker outputs from a single input. Pull out
the link supplied and use it to connect the
sockets together. Using one power amplifier per loudspeaker
will enable you to bi-amplify bi-wireable loudspeakers.
This is particularly beneficial for top quality stereo installations
with a separate pre-amplifier, or where amplifiers are provided
for the left, centre and right channel loudspeakers in a five
speaker Dolby Pro Logic or Dolby Digital system.
Contact your Arcam dealer for more information.
"Daisy chaining" – The power amplifier can be connected to
further power amplifiers to drive more speakers (e.g. those in
other rooms or tri-amplified speakers, etc).
Connect the extra power amplifier inputs to the
sockets on the power amplifier, left to left, right to right.

Remote switching

By making a connection from the
power amplifier to the
amplifier, you can use the A90 to switch the power amplifier on
and off. If configured in this way, the front panel
of the A90 (or the
control) switches both amplifiers on and off together. This facility
allows you to conceal the power amplifier yet still control it.
The connecting cable required is a 3.5mm to 3.5mm jack lead

Three channel option

The power amplifier 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
P90 into a 3 x 90W (RMS per channel into 8Ω) amplifier suitable
