QUEST Digital Power Amplifier 4 x 280 Watt
The QX-280 range consists of three, separate 280 Watt per channel models, available as single, two channel, and four channel variants.
Audio quality is studio class in both high and low impedance operation. High quality class D amplifier technology makes it possible to have a compact single rack format with the right combination of power and channel density.
The transformerless outputs deliver full range audio to all impedance loads from 4Ω to 70/100V systems. Each amplifier channel has a selectable 80 Hz high-pass filter (selectable via a swith located on the rear panel), and a volume control for each channel that can be accessed directly from the front panel. Each amplifier channel is also provided with a thermally controlled cooling fan.
