FUNCTIONAL FEATURES
Overload and Short-Circuit Protection
Individual per each channel. This protective system becomes active in case of short-
circuited output or overload caused by reduced load impedance. It disables the output
signal of the respective channel for 0.5 second and then the amplifier gradually resumes
its delivery.
DC Output Protection
The amplifier’s schematics precludes transit of any clicks or noise during the power-
on/off transition process. The power source unit is responsible for preventing any DC
damage to loudspeakers. In the event of output DC voltage or any powerful LF
fluctuations, the power source unit goes off and all indicators, including the POWER LED,
go off too.
The amplifier can be restarted in 2 or 3 minutes by de-energizing and re-energizing
the amplifier with the POWER switch. If the DC is an occasional problem (which is unlikely)
the amplifier goes on and resumes its normal functioning. If, otherwise, the DC output
problem persists through the fault of the amplifier, then upon switching, the amplifier goes
on, the POWER amplifier goes on but in a short while the DC output protection system
disables the power supply source.
Thermal Protection
Independent for each channel. In this case upon reaching 85°C, the independent
protection system disables the respective channel of the amplifier. The CLIP LED goes on
and the SIGNAL LED of the affected channel goes off.
As soon as the amplifier cools down, the affected channels gradually regain their
amplification level up to the set value.
Soft Signal Start
During the power-on process, this feature ensures smooth gain from zero to the
maximum level to provide for a smooth rise of the sound level emitted from the loud-
speakers.
