7.4 Audio Input and Output con-

nections, setup and features

7.4.1 Balanced / Unbalanced Input connection

Two electronically balanced Phoenix-type inputs are

available. Follow the +,– and Ground labels when

connecting the input signal.

If an unbalanced connection is desired this can be

achieved by summing the minus (“COLD”) and

Ground terminals and using the + terminal as the

“HOT” signal. For the best possible performance,

the summing of ground and minus wires should be

done at the source unit end of the cable (e.g. a CD

player).

Four connectors are supplied for attaching cables to

the inputs. The type of connector used is: Phoenix

Contacts, Part number MSTB 2,5/3-STZ-5,08

When linking the same source signal to

several input channels, be aware that there

is a limit to the number of channels an

output source can “drive”. A typical output

source (e.g. a DSP crossover unit) can drive up to 4

ampliﬁer channels before line-drivers would be

required to buffer the signal.

7.4.2 Output operation and connection

Screw-terminal connectors with + and – poles are

provided at each channel output for connection of

the speakers.

Make sure that the speaker cables are connected

correctly and tightly, and that accurate polarity is

maintained to all speakers in the system.

As the ampliﬁer outputs produce high voltage,

do not connect or disconnect speaker cables

when the mains power is on. Also, attach the safety

cover on the speaker terminals for safe operation

and to comply with electrical product approvals.
