The MA3.2S can warm up considerably - depending on the required output power. It is therefore very
important that air circulation is possible to both the sides and underside of the unit and that heated air can
vent upwards. This will allow good heat dispersion. If the unit is placed on a carpet you should ensure that
the feet do not sink into the pile (if necessary place blocks underneath) and that air vents are not sealed by
the pile of the carpet. Please also ensure the unit is protected from direct sunlight.
2.3 Power supply and initial check
Do not connect your loudspeakers when taking the unit into use for the first time. Set the mains switch (9) to
"0", set the mode selector switch (7) to "auto", and leave the inputs open. Connect the power supply socket
(9) with a cable to the mains and set the mains switch (10) to "I". The control LED (1) glows. The unit is now
in "stand-by" mode. Operating voltage is only being supplied to the automatic start up circuitry. The
remaining amplifier circuitry is without power.
Set the mode selector (7) to "permanent". Now the LED (1) lights up. At this moment you will hear clicks in
short succession from the switching relays of the supply unit and speaker output. The amp is activated.
When this initial check is passed, switch the amp off.
2.4 Selecting operation mode
2.4.1 Auto
The incorporated automatic start circuitry relieves you of switching the Mono amp on and off when the mode
selector (7) is set to "auto". For this the main supply switch (10) must always be set to "I". Your MA3.2S then
switches on automatically as soon as the pre amplifier delivers musical signals and off when the pre amplifier
has not delivered a signal for more than about 5 minutes.
2.4.2 Permanent
If you wish to switch the MA3.2S personally on or switchable mains sockets are used you can set the mode
selector (7) to "permanent" and activate the unit with the main supply switch.
2.4.3 Trigger
If your preamplifier is equipped with a trigger output you can connect this output to the MA3.2S's trigger input
(6), (see also 2.1.4 connection trigger input) and set the MA3.2S's mode selector (7) to "trigger". Then the
MA3.2S will switch on and off simultaneously with your preamplifier.
2.5 Remote control via audio cable
If you use an AVM pre amplifier of the newest Generation (PA3.2, PA8) then this unit will automatically be
switched on and off by an inaudible digital signal via the connected audio cable. There is no need for an
additional trigger cable. Set the MA3.2S's mode selector (7) to "trigger". Then the MA3.2S will switch on and
off simultaneously with your preamplifier.
NOTE: While the MA3.2S is in stand-by mode, the device is not completely separated from the mains
supply. To protect your unit from damage during a thunderstorm or prolonged absence, it is recommended
that you disconnect the mains plug (9).
