Connecting to power, loudspeakers and
other equipment
Follow the installation instructions for the integrated amplifier on
pages 4 and 5.
AUDIO IN
– Connect this input to the output sockets of your pre-
amplifier or the
PRE OUT
sockets of an integrated amplifier.
MONO LINK
– The power amplifier 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 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
AUDIO OUT
sockets on the power amplifier, 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 amplifier to the
TRIG OUT
socket of the A90 integrated
amplifier, you can use the A90 to switch the power amplifier on
and off. If configured in this way, the front panel
POWER
button
of the A90 (or the
POWER/STANDBY
button on the remote
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
(stereo or mono) and it is possible to connect several power
amplifiers to an A90 by ‘daisy chaining’ from
TRIG OUT
of one
P90 into the
REMOTE IN
of the next.
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
AUDIO IN
and
OUT
phono sockets and converts the
P90 into a 3 x 90W (RMS per channel into 8Ω) amplifier suitable
for Home Cinema or multi-channel audio use.
Contact your Arcam dealer for further details.
