Fan cooling
The power amplifier has two fans. The fans are switched in three performance-optimized
levels, for example they are not running permanently but the speed of the fans is controlled
depending on the temperature. That in return ensures very silent operation during idle state.
The temperatures of the power amp's channels are supervised and monitored individually.
