Quadruple the power, endless possibilities. The G6-4CH provides four independent channels of pure Class H power (4 x 850W at 4 Ω), allowing you to drive a massive stereo bi-amped system (lows and highs separately) or four distinct zones from a single 2U rack unit. If you are building a complex, high-SPL audio system for a massive festival stage or a multi-room superclub, this amplifier delivers unparalleled headroom and reliability.
