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 and then the amplifier gradually resumes its level. As
overload protection activates, so lits the PROT LED the corresponding channels pair.
Thermal Protection
Independent for each pair of channels. In this case upon reaching 85°C, the indepen-
dent protection system disables the respective pair of amplifier channels. The CLIP LED
goes on and the SIGNAL LED of the affected pair of channels goes off.
As soon as the amplifier cools down, the affected channels gradually regain their
level up to the set value.
Soft Signal Start
During the power-on process, this feature ensures smooth gain from zero to the set
level to provide for a smooth rise of the sound level in the loudspeakers.
AUTO STANDBY Mode
As the signal is not applied to all inputs for more than 5 minutes, STANDBY mode
activates. All amplifier units are OFF. As 0.1 sec duration signal with more that -60 dBu
level appears at any input, all amp units are ON.
This mode can disabled by AUTO STANDBY switch on the rear panel.
