SHORTED OUTPUT DETECTION

If the output of the amplifier becomes shorted, the front panel

indicator will turn red and the amplifier will turn off the output stage

for about three seconds, then very briefly try to turn on again. If the short

still exists, this cycle will repeat until the short circuit is removed.

THERMAL PROTECTION

A thermal protection circuit prevents high case temperatures which

are unpleasant to the touch and potentially harmful to the amplifier. The

thermal cutout circuit will mute the amplifier when the transistor cases

reach 85°C, and the indicator will turn red.

If this happens, more ventilation should be provided for the

amplifiers.

MAINTENANCE

No routine maintenance is required for the Boulder 860 Stereo Power

Amplifier. However, to keep operating temperatures at a minimum, do

not block the heat sinks, and remove any dust buildup that may occur.
