APC power management circuitry

 constantly analyses incoming music signals 

and keeps dynamics alive. An additional ultra fast peak limiter avoids amplifier clipping in case 

someone hits the inputs too hard. Please remember, this is a musical amplifier, please leave 

some headroom and enjoy the music.

 APC also allows you to configure the amplifier to your specific needs: average RMS output 

• 

power is programmable from 150 to 600 watts. Under all circumstances dynamic headroom is 

respected as long as you don’t overload the input stage. This circuit can also be used as an 

environmental noise limiter.

 Output sound selection: tube emulation circuitry for authentic sound from tube amplifiers. Solid 

• 

for normal use. Try to find out and discover the subtle sonic differences.

 Bridge or stereo mode: double the output power and convert this amplifier into a monoblock 

• 

amplifier with one push on a button. Minimum load impedance is 8 ohms in bridge mode.

 Protection circuitry: the protection circuitry is another unique design feature of this amplifier: 

• 

together with the APC circuitry, output signals are constantly monitored by the protection circuit, 
and speaker outputs will be cut in case of extreme overload, short circuits, DC offset, overheat

-

ing… This circuit is also capable (within certain limits) of reducing the input signal to prevent 

clipping, distortion and other musically destructive situations. We have done our best to make 

sure this amplifier will produce clean power, but 

it is also the user who is responsible for the 

final result

 Versatile in- and output connector configuration for increased installation flexibility.

• 

 User protected power and sound setting switches at the rear, accessible behind a removable 

• 

cover plate.

 Ground lift switch to enable you to find the cause of system ground loops.
