Connecting to loudspeakers

Wiring strategies

There are three different wiring strategies that can be employed to connect your P1000 to your speakers. Your choice will be limited by what your speakers can support.

Single wiring is the conventional wiring system of running a single cable per channel
between the amplifier and the speaker.	Before you start!

by the different currents interacting with one-another within a single cable, as occurs in
conventionally wired systems.
Note that some speakers have three pairs of terminals on the back, extending the bi-
wiring principle to tri-wiring.

<Bi-amping

The performance of your system can be enhanced further by extending the signal-separation principle to include separate amplification for the low- and high-frequency drivers in each speaker. You will require two amplifiers to do this.

English

Single wiring

The speaker terminals for any given channel are labelled clearly on the rear of the P1000. For each channel, connect the positive terminal of the speaker connection on the P1000 for that channel (coloured red and labelled with ‘+’) to the positive terminal of your speaker for the channel (connect, for example, the positive terminal of the centre channel of the P1000 to the positive channel of your centre speaker). Similarly, connect the negative terminal of the amplifier (coloured black and labelled with ‘–’) to the negative terminal of your speaker. If your speaker supports bi-wiring (i.e., it has more than one set of connecting terminals), but you do not wish to use bi-wiring, connect the P1000 to the terminals labelled LF or Low Frequency. There should be a strip of metal on the speakers connecting the low-frequency terminals to those for the higher- frequencies; this must not be removed in a single-wired system.

Follow the above instructions for each speaker in your system, ensuring that the speakers are connected to the correct output of the P1000. You do not have to connect speakers to all the channels of the P1000 (e.g., if you don’t have a centre speaker, it doesn’t matter).

Bi-wiring

Bi-wiring is performed in the same way as single wiring except that, for each speaker, a pair of cables is used to connect the positive terminal of the amplifier to the speaker. One of the cables must be connected to the lower of the two positive terminals on Alto, with the other cable connected to the higher positive terminal. The negative terminals must be connected in a similar manner. The connecting strip of metal on the speakers connecting the lower terminals to the upper terminals must be removed for bi-wiring.
