1KHz, 0.001% THD+N

8 Ohm Stereo per channel 550w

 

4 Ohm Stereo per channel 850w

 

2 Ohm Stereo per channel 1250w

 

Max output RMS per channel       1250w

Max peak output per channel       1400w

Audio Crossover

– Electronic audio crossover that can be inserted individually in every channel(4 independent crossovers)

– 12 dB/oct. 3 cut-off frequencies selectable from the front panel

– Cut-off frequencies Low Pass: 113-145-3200 Hz (factory settings)

– Cut-off frequencies High Pass: 113-145-3200 Hz (factory settings)

– When the High Pass and the Low Pass are selected at the same time the result is a Band Pass with the chosen cut-off frequencies

– When no cut-off frequency is chosen the amplifier is linear

Limiter

– Optical limiter that can be inserted individually in every channel (4 independent limiter)

Bridge

– Insertable channel A+B (adjustable using channel A) and channel C+D (adjustable using channel C)

– Minimum applicable load 4 Ohm.

– Speakon output connectors channel A: 1+ positive 2+ negative

– Speakon output connectors channel C: 1+ positive 2+ negative
