Single wiring

If each speaker has more than one pair of connecting terminals, use the terminals labelled

or ‘Low Frequency’ for each speaker.

Connect the positive terminal of the right speaker connection on the amplifier (coloured

red and labelled

) to the positive terminal of your right speaker. Similarly, connect the

negative terminal of the amplifier (coloured black and labelled with

R–

) to the negative

terminal of your speaker. Repeat the process for the left speaker, using the amplifier

terminals labelled

and

l–

If your speakers support bi-wiring, then there is a strip of conductive 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.

bi-wiring

Bi-wiring is performed in the same way as single wiring except that, for each speaker, a

pair of cables are used to connect the amplifier to each speaker.
Follow the instructions given for single wiring; then perform the same actions, this time

connecting the upper set of speaker terminals on your amplifier to the terminals labelled

or ‘High Frequency’ for each speaker. Please refer to the illustration.

Speakers that support bi-wiring have a strip of metal on the speakers connecting the low-

frequency terminals to those for the higher-frequencies; this MUST BE REMOVED in a

bi-wired system.

bi-amping

Bi-amping requires the use of two amplifier channels per speaker. Using this method will

prevent you from using seven surround speakers.
Connect two channels of the P777 with a phono cable between the

AudIo ouT

socket on

one channel to the

AudIo IN

channel of another. One channel should then be connected to

the speakers as described for single wiring, with the exception that this channel should be

connected to the speaker terminals labelled

or ‘High Frequency’. The second channel must

then be connected to the

or ‘Low Frequency’ terminals, as in the diagram.

Note that the strip of metal on the speakers connecting the lower terminals to the upper

terminals MUST BE REMOVED. Failure to do so will result in damage to both amplifiers,

which will not normally be covered under warranty.
Arcam recommends that the phono connections are use for bi-amping. If you prefer to use the

XLR connectors, use a Y-lead with one female XLR to two male XLRs, so that two amplifier

channels may be fed from a single source. Contact your dealer if you need assistance.
