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).
