Arcam MULTI ZONE POWER AMPLIFIER MZ8 - Manual (Page 8)

Speaker Installation
The MZ12 amplifier allows the connection of up to twelve independent
loudspeaker channels, arranged in six stereo zones. The MZ8 amplifier
provides eight channels in four zones. Each zone is designed to provide
amplification to one room of a multi-room installation; further options
allow for greater flexibility when installing multiple loudspeaker pairs in
a large space.
Connecting speakers
The MZ amplifiers are designed to drive full bandwidth speakers, rated
between 4 and 8 ohms. The unit is fitted with speaker terminals that can
accept either spade terminals or bare wires. Arcam’s Muso speakers are
compact mini-monitor speakers which ideally match the design values
and output characteristics of the MZ amplifier series. Your dealer will
be able to advise you of suitable loudspeakers for other applications, for
example in-ceiling use.
single wiring
Single wiring is the conventional wiring method of running a single cable
per channel between the amplifier and the speaker; this is the easiest
technique.
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
amplifier (coloured red and labelled +R) 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 +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.
