| Protections: | ||
| DC protection: | protects against infrasonic signals and output stage fault |
|
| 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. |
|
