The M6si500 is a super integrated amplifier that delivers 500 watts per channel into 8 ohms. It has five inputs: four line inputs and one balanced XLR. It also has preamp and fixed line outputs and a home theater bypass.
Internally, it is a separate preamp with two independent monobloc power amps. The design is dual-mono: each power amp section has its own heat sink and separate transformer, and the preamp has its own power-supply winding. Each channel uses 12 bipolar transistors and can supply 200 amps peak-to-peak.
The front panel is a fine-line extrusion of military-grade aluminum. The heatsinks are custom-made for heat dissipation. The five input sockets connect directly to the main preamp circuit board instead of through wires, which keeps the signal path short. A digital volume control with laser-trimmed substrate resistors keeps channel tracking accurate at very low listening levels.
