USER MANUAL
2 DESCRIPTION OF CONTROLS:
2.1
BEFORE SWITCHING THE DEVICE ON:
1- Make sure that the power supply circuits are properly dimensioned and
that the power voltage is stable. To dimension the circuits, check the
technical characteristics of the specific model.
2- Make sure there is correct air circulation from the front of the device
towards the back, and avoid obstructing the air flow. This device has
forced ventilation at variable speed depending on the dissipation needs,
in order to maintain the best operation temperature. Blocking the air inlets
or outlets can cause overheating of the device. In case of overheating the
system will protect itself by cutting the audio signal until it recovers the
optimum operating temperature.
3- Check that the loudspeaker lines connected to the amplifier channels
exceed the minimum specified impedance for nominal channel power.
