Amplifier Classes
There have been many developments in audio electronics, resulting in different amplifier circuit designs. Such designs can be divided into classes, of which 4 main types are relevant to audio – A, AB, H and D.

19" rackmount 2U power amplifiers with dual fan cooling and class H architecture for safe, reliable power delivery. Balanced inputs via XLR sockets, speaker outputs on 2 SPK connectors or 4mm binding posts. High power output stable down to 2 Ohms load per side can also be bridged mono to 4 Ohms. Switchable ground lift, bridge mode and clip limiter.
