AV 5.1k Amplifier | 1650 W total power | 2 x 75 W @ 4ohm + 2 x 250 W @ 2ohm + 1 x 1000 W @ 2ohm | AB-class

AV 5.1k, 1650 W (RMS) max, five channels: with its hybrid design, it is the specialist amplifier for front + rear + subwoofer or multi-amplified front + subwoofer systems.

Its high-quality AB Class output stage provides two channels with 250 W (RMS), combined with another pair of A class pure audio channels rated at 75 W (RMS), perfect for active two-way front speaker systems.

The D Class mono section provides 1000 W (RMS) for powerful subwoofer output.

AV 5.1k also allows you to replace the analog input board with the digital one (AV bit IN).
