connecting to loudspeakers

The P38 amplifier may be connected by simple wiring,
bi-wiring or bi-amping – see page 9 for details. In
addition, see the following section on the Mono Link
(and the diagram below) for another way of bi-amping
loudspeakers using a pair of P38s.

other connections

The P38 amplifier provides the following connections:
audio in
Connect the output sockets of your pre-amp. (or the
sockets of an integrated amplifier, such as the
PrE out
A38) to one of these inputs.
Mono link
The P38 can be adapted to provide two mono
loudspeaker outputs from a single input. Using a pair of
P38s (i.e. one power amplifier per loudspeaker) enables
you to bi-amplify a pair of compatible loudspeakers,
reducing the amount of cross-talk between channels
compared with using the P38 in a more conventional
stereo configuration.
1. Connect the channel from your pre-amp
rIGht
(or from an A38) to the socket labelled
PrE out r
on your first P38.
AudIo In r
2. Pull out the link supplied on the back panel
(labelled 'link'), and use it to connect the left and
���������
right sockets together.

3. Repeat steps 1 and 2 on your second P38, but
���������
this time connect the channel from your
LEft
pre-amp (or from an A38) to the socket
PrE out L
labelled .

4. Follow the diagram (left) for bi-wiring each
speaker, using the connections of the P38
sP2
for the high-frequency speaker and the
connections for the low-frequencies in each case.

daisy chaining more amplifiers
The P38 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
pre-amp input of the next amplifier in series, left to left,
right to right.
Note that daisy-chaining cannot be used if the Mono
Link (previously described) is in use.
