Single wiring
If each speaker has more than one pair of connecting terminals, use the terminals labelled
LF or ‘Low Frequency’ for each speaker.
Connect the positive terminal of the right speaker connection on the amplier (coloured
red and labelled
+R) to the positive terminal of your right speaker. Similarly, connect the
negative terminal of the amplier (coloured black and labelled with R) to the negative
terminal of your speaker. Repeat the process for the le speaker, using the amplier
terminals labelled +L 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 amplier 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 amplier to the terminals labelled
HF 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 amplier 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 HF or ‘High Frequency’. e second channel must
then be connected to the LF 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 ampliers,
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 amplier
channels may be fed from a single source. Contact your dealer if you need assistance.
