D Series 4-Channel Class-H Power Amplifier

Compact multi-channel workhorse — 4 independent channels, each bridgeable, 300W to 1950W per channel

4 channels2UClass-H 2-stage19–32kg

One amp, many jobs: four independent channels, or bridge pairs — runs as 2, 3 or 4 channels to fit any zone plan
Class-H two-stage output circuit — high efficiency with plenty of current headroom
Rich high-frequency detail with strong vocal penetration; deep, elastic low end from generous current reserve
Direct-coupled output devices on waved copper heatsinks — 30% better cooling than aluminium; smart variable-speed fans
Full protection set: DC, short-circuit, overload, over-heat, clipping distortion and power-on inrush
2.0mm steel chassis with 2.5mm aluminium panel — 482×460×88mm, 19 to 32kg depending on model
