Do not attempt to use both the LOW IMPEDANCE output and the C.V. OUTPUTS at the same time.
Failure to observe this restriction is likely to result in permanent damage to the amplifier power stage.

AUX OUT – a balanced output on a 3-pin, 3.5 mm-pitch screw-terminal connector. See rear panel for pinout; a mating
connector is supplied. This connector carries a line level signal derived from the output of the mixer stage and is suitable
for connecting to the inputs of additional power amplifiers. The output is a mix of both music and microphone signals and
will be affected by any priority settings. All the front panel MICROPHONES and MUSIC controls will affect the signal at
the auxiliary output, but it is not affected by any of the MASTER controls..
6.
MUSIC MUTE – a 2-pin, 5 mm-pitch screw-terminal connector. Shorting the pins together will mute the music content
of the mixer-amplifier's outputs, including the Auxiliary Output, and Line Input 1 if Line 1 Priority is selected and currently
active (see [4] on front panel). Microphones will remain active. Connecting MUSIC MUTE to a suitable pair of normally-
open contacts on a fire alarm panel (or similar system) may aid compliance with local emergency regulations. If it is
desirable to mute the microphone inputs as well as the music signal, an internal jumper can be moved to permit this: see
"Table of internal jumpers" on page 10.
7.
POWER INPUT – connect AC mains here using the cable supplied, which will have a mains plug suitable for your territory.
Only use a 3-wire connection, to ensure the unit is earthed (grounded). The POWER INPUT connector incorporates a
fuse holder – see page 4 for fuse data.
8.
Fan – the VMA120 and VMA240 are forced-air cooled. Ensure there is adequate space at the rear of the chassis for airflow
and that the fan is not obstructed. The internal protection circuitry incorporates temperature sensing, and the mixer-
amplifier will shut down in the event of overheating.
