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 PRE OUT sockets of an integrated amplifier, such as the 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.

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 sockets on the P38 to the 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.

1.Connect the RIGHT channel from your pre‑amp (or PRE OUT R from an A38) to the socket labelled Audio In R on your first P38.

2.Pull out the link supplied on the back panel (labelled ‘link’), and use it to connect the left and right AUDIO OUT sockets together.

3.Repeat steps 1 and 2 on your second P38, but this time connect the LEFT channel from your pre‑amp (or PRE OUT L from an A38) to the socket labelled Audio In L.

4.Follow the diagram (left) for bi-wiring each speaker, using the SP2 connections of the P38 for the high-frequency speaker and the SP1 connections for the low-frequencies in each case.
