Protections circuitry

DC protection: protects against infrasonic signals

VHF protection: protects the loudspeakers against strong very high frequency non-musical signals above the audible range.

Thermal protection: prevents the amplifier from being overheated. The protection indicators on the front panel are switched on, as a warning, before the protection process is initiated.

AC protection: shuts down the power supply if the line voltage is outside the operating voltage.

Clip limiter: prevents severely clipped waveforms from reaching the loudspeakers, whilst maintaining full peak power.
