CONNECTING TO POWER, SPEAKERS, and
OTHER EQUIPMENT
Follow the guidelines for the integrated amplifier in this handbook.
9
PWR AMP IN
Connect this input to the output sockets of your
pre-amplifier or the PRE-AMP OUT sockets of an integrated
ampIifier.
bn
MONO LINK
The integrated amplifier can be adapted to provide two
mono loudspeaker outputs from a single input.
bn
Pull out the U-link
supplied and use it to connect the
LINK OUT sockets together.
Utilising 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 for the left, centre and right channel loud
speakers in a five speaker Dolby Pro Logic™ or Dolby
Digital™ system.
Contact your Arcam dealer for more detailed information.
DAISY CHAIN
The power amplifier is capable of driving further power
amplifiers (or any other power amplifier), to drive more
speakers (e.g. those in other rooms or tri-amplified speakers
etc). Connect the extra power amplifier inputs to the LINK
OUT sockets on the power amplifier, left to left, right to right.

P25 REMOTE SWITCHING
By making a connection from the 'control out' socket
3
of the A22 to the 'control in' socket
amplifier you can use the A22 to control the power mode
of the power amplifier. If configured in this way the front
panel power button of the A22 (or remote control standby
button) will switch both amplifiers on or off simultaneously.
This facility allows you to hide the power amplifier out of
sight and still be able to control its functions.
The connecting cable required is a 3.5mm to 3.5mm jack
lead (stereo or mono) and it is possible to connect several
P25 power amplifiers to an integrated A22 by 'daisy chaining'
from 'control out' of one into the 'control in' of the next as
shown in the diagram at the bottom of the page.

THIRD CHANNEL OPTION
,
This option enables you to have a 5 channel amplifier when
used with a suitable integrated amplifier, to create a high
quality Home Cinema setup.
The third channel can be used to drive the centre speaker.
For connection details see DAVE amplifier 'Setting up'.
Please contact your dealer for availability of this module.
Now you have finished 'Setting up', return to the 'User Guide'.
