QX4280 4 X 280 WATT POWER AMPLIFIER 4 OHM & 70/100V

QX-280 SERIES CORPORATE POWER AMPLIFIERS   MADE IN AUSTRALIA Like all Quest products, the QX-280 Series is made to survive in a tough world. Australian QC and advanced design engineering mean years of trouble free service in professional applications. The QX-280 Series provides a price/performance ratio thatis hard to beat.   Studio quality sound and plenty of channels - the QX-280 Series is available in a wide range of single and multi-channel configurations. Specifically designed for AV installations and high endcommercial sound, where hi-fidelity audio is required. Powered with the latest in high quality, energy efficient, Class D amplifiers; the QX-280 Series amplifiers can be integrated into both low impedance, and 70/100V line installations without compromise A CLOSER LOOK The QX-280 range consists of three separate models. QX1280 - single channel x 280 Watt QX2280 - two channels x 280 watts QX4280 - four channel x 280 watts 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 toall 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 rearpanel), 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.
