Amplifier Gain Switch (P1)
This switch is to allow the gain of the P1 amplifier to be changed to suit your system requirements.
With the switch in, the gain is set to standard ARCAM gain of 31.5dB. This is the normal setting,
which allows the P1 to be used in systems where there are other ARCAM power amplifiers (excluding
the Arcam P7).
With the switch out, the gain is set to ‘THX standard gain’. Use this setting if your P1 is to be used in
systems containing amplifiers with THX gain (for example, the Arcam P7).
Daisy chaining
Both the P35 and the P1 can be connected to further power amplifiers to drive more speakers (e.g.,
those in other rooms, tri-amplified speakers, etc). This technique is called ‘Daisy chaining’.
Connect the
AUDIO OUT sockets on the P35/P1 to the pre-amp. input of the next amplifier in series, left
to left, right to right.
Remote switching
By making a connection from the TRIG OUT socket of the C31 pre-amp. to the REMOTE IN socket of
your P35/P1, you can use the C31 to switch the power amplifier on and off. If configured in this way,
the front panel
POWER button of the C31 (or the POWER button on the remote control) switches both
amplifiers on and off together. This facility allows you to position your power amplifier in a remote
location (such as close to the speaker it is amplifying), yet still control it.
The connecting cable to use is a 3.5mm jack lead, wired as given on page 5. It is possible to connect
several power amplifiers to a C31 by ‘daisy chaining’ from the
TRIG OUT of one power amplifier into the
REMOTE IN of the next.
