Inter-M Americas Inc QD-4240

The QD-4240/4480/4960 are four-channel amplifiers capable of driving 4 ohm loads. Their clean sound quality makes them ideal for permanent installation in professional PA systems or for portable use for live performances.

Inputs are XLR/ TRS "Combo" connectors; outputs are via rugged five-way binding post connectors. Clip-limiters are supplied on each channel to help prevent distortion due to excessive signal levels. All units have soft-start protection circuitry and feature power, signal, protection, and clip indicators on the front panel.

For added versatility, they may be operated in stereo, dual mono or bridged mono mode. The quad series amplifiers are powered by 100-120VAC or 220-240VAC 50/60Hz (depending on country requirements) and are packaged in 3.5" (2RU) high rack mount enclosures.
