Description
4 channels Analog Audio Amplifier class AB with toroidal transformer.
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
