Let's start with the Voce AV 5.1k, a 5-channel amplifier from the manufacturer Audison. This amplifier does not pale in comparison to standard performances but shines with an impressive total output of 1650 W. It stands out with its hybrid design and the ability to support front, rear, and subwoofer systems or even realize multiple amplified front and subwoofer systems. Each channel comes with individual power ratings, with a pair of A-Class audio channels at 75 W and another pair of AB-Class channels at 250 W, while the mono section of Class D stands out with a power of 1000 W. A special feature of the AV 5.1k is also the ability to replace the analog input card with a digital one.
