Speaker Installation

e MZ12 amplier allows the connection of up to twelve independent

loudspeaker channels, arranged in six stereo zones. e MZ8 amplier

provides eight channels in four zones. Each zone is designed to provide

amplication to one room of a multi-room installation; further options

allow for greater exibility when installing multiple loudspeaker pairs in

a large space.

Connecting speakers

e MZ ampliers are designed to drive full bandwidth speakers, rated

between 4 and 8 ohms. e unit is tted 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 amplier 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 amplier 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

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.
