Some putative defects are often caused by small mistakes in operation. Sometimes, other
units connected to the amplifier may cause problems, too. We therefore kindly ask you to
read the following tips first, before consulting your dealer or us.
1. No playback
a) First of all, please check whether the pre-amplifier and the selected signal source are
operating correctly. This is best achieved by checking the functioning of the pre-amplifier
by using some headphones. Remember to remove the headphones afterwards, otherwise
the pre-amplifier will not emit a signal to the MA / SA 6.2.
b) Ensure there are no breaks or short circuits in the signal cable between the amplifier and
the pre-amplifier.
c) Check the connecting cable between the amplifier and the loudspeakers for a short circuit
or break.
d) Inadvertent switching to standby. Press the power button (1). If the LED indicator and
display do not light up, a fuse can be blown due to overvoltage (e.g. in case of a
thunderstorm etc.). Please contact your dealer.
2. The unit does not switch from STANDBY to
music from OPERATE to STAND BY
a) This can happen when the amplifier is operated in auto mode and you are listening at low
levels. Then the incoming voltage from the pre-amplifier is too low to trigger the auto-
circuit. In this case, we recommend to switch the unit to permanent mode or to make use
of a trigger cable (see section 1.6).
b) If the unit is operated in trigger mode, please check the trigger cables between the pre-
amplifier and the amplifier and ensure there are no breaks or short circuits in the cable.
c) The unit is operated in remote mode without using a suitable pre-amplifier (such as an
AVM SD or PA model). Choose a different operating mode (see section 2.6).
3. After switching off the pre-amplifier the amp does not automatically switch to
STANDBY (after approx. 5-10 min.) although the "auto" mode is selected
a) Please check whether a low humming or chirping noise is heard from the loudspeakers
after switching off the pre-amplifier. If there is such a noise, scattering emissions within
the cable are interfering with the automatic switch-on circuitry. The unit is interpreting the
interference as a music signal and reacts by not switching off the amp. Avoid interferences
by placing the cable. Place your cable differently. With balanced XLR cables, this fault can
also arise from errors in the pin setting (see section 1.2.3).
4. The amplifier switches off during normal operation
a) This can happen if the temperature inside the unit becomes too high. In this case, the
amplifier switches off and the display shows overheat. Switch off the unit and let it cool
down for some minutes.
