Inputs
Connect the input signal to the ¼” mono jack socket on the rear
panel. Use a screened cable for the input signal to avoid
interference. If connecting from a stereo output, use a ¼” stereo jack
plug to two ¼” mono jack plugs splitter lead such as G038TR (1
metre) or G038TS (5 metre).
Outputs
Connect the speakers to the 4-pole loudspeaker output connectors
on the rear panel, using the 1/+ and 1/- terminals. Use a Speakon-
Speakon lead, or a Speakon–female XLR lead.
A Speakon–¼" jack lead or a Speakon–male XLR lead MUST NOT be
used with this amplifier, due to the risk of electric shock, (and is
forbidden by the Electricity at Work Regulations)
Any number of speakers may be connected to each channel, as long
as the combined impedance is not less than 4
W
. Connecting more
speakers reduces the impedance. Connecting too low an impedance
may damage the amplifier.
If one of the outputs is not being used, it is not necessary to connect
any load to it.
For speakers connected in PARALLEL on each channel:
