M2 CONNECTIONS
The M2 should be connected immediately preceding the power amplifier(s)
and after any such devices as preamps, mixing desks or other equalisers.
Input connections, which are balanced, are via combination XLR type
sockets and TRS (tip/ring/sleeve) "stereo" jack sockets, wired as follows:
Pin 1 / jack sleeve
=
Signal 0V
Pin 2 / jack tip
=
(hot)
Pin 3 / jack ring
=
Signal - (cold)
If driving the M2 from an unbalanced source, mono jack plugs may be
used. Under some conditions, this may result in a hum loop. If so,
alternative connections, via an XLR type plug or a TRS jack should be
used, wired as follows:
Pin 1 / jack sleeve
=
Not connected
Pin 2 / jack tip
=
Cable inner (signal)
Pin 3 / jack ring
=
Cable screen (ground)
M2 outputs are pseudo balanced on stereo jack sockets.
Pin 1 / jack sleeve
=
Signal 0V
Pin 2 / jack tip
=
(hot)
Pin 3 / jack ring
=
Signal - (cold)

M2 OPERATION
The M2 is a full range 2-channel system controller which is recommended
for use with the Martin Audio ICT500 loudspeaker system. If extra sub
bass cabinets are required the M2 has a dedicated sub bass output TRS
jack socket. This output is a left and right mono summed output providing
the correct crossover point and equalisation to drive additional sub bass
amplifiers.
