Connecting to power, loudspeakers and
other equipment
Follow the installation instructions for the amplier on pages
4–6.
AUDIO IN
Connect this input to the output sockets of your pre-amplier or
the PRE OUT sockets of an 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: P80 power amplifer
Remote switching
By making a connection from the REMOTE IN socket of the P80
power amplier to the TRIG OUT socket of the A80 amplier,
you can use the A80 to switch the power amplier on and off.
If congured in this way, the front panel POWER button of the
A80 (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 male 3.5mm to male 3.5mm
jack lead (stereo or mono) and it is possible to connect several
power ampliers to an A80 by ‘daisy chaining’ from TRIG OUT of
one P80 into the REMOTE IN of the next.
Signal detect
The P80 power amplier features a signal-detecting circuit
that automatically switches the unit on when an input signal
is delivered to the amplier. The unit switches into standby
approximately 12 minutes after the signal source is switched
off.
The signal detect feature is disabled by the supplied blank plug,
or when a connection from the REMOTE IN socket to TRIG OUT
of an A80 is made. Simply remove the blank plug from the
REMOTE IN socket if you wish to use this feature.
