Description
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 a powerful subwoofer output. AV 5.1k also allows you to replace the analog input board with the digital one (AV bit IN).
Power Output
Hi-Res audio
According to the definition of HiRes audio provided by JAS (Japan Audio Society – jas-audio.or.jp), Voce amplifiers exceed the above 40 kHz bandwith analog requirement, providing an astonishing 4 ÷ 60k Hz (@ -3 dB, 2 VRMS, 4 Ω).
