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  power  off  and  power  on  the 

amplifier with the POWER switch. If the DC is an occasional problem (which is unlikely) the 
amplifier  goes  on  and  resumes  its  normal  operation.  If  the  DC  output  voltage  is  still 
present, the protection system will again turn off the power supply.

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 rise amplification level 

from zero to the set value.
