2.2 Placement of the unit / cooling

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.

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.

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.

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.

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.

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).
