The QD-4480 is a four-channel power amplifier capable of driving loads from 4Ω. Its clean sound quality makes it ideal for permanent installation in professional PA systems or for portable use in live performances. Primarily designed for multi-zone use such as in bars and restaurants, where separate control of music in different areas is required, these designs can be applicable for use in any situation where a number of low-power amplifiers is needed, such as for cue-feed, effects speakers, museum exhibitions, etc. Three models are available; each combines four separate low-impedance amplifiers in a single 2U rack-mounted enclosure. Each amplifier features an individual balanced XLR/TRS "Combo" input connector, a level control with associated presence and clip LEDs, and 5-way speaker output terminals. For added versatility, an input selector allows each pair of amplifiers to be driven separately (stereo), with parallel inputs (dual mono), or bridged in mono. Clip limiters are provided on each channel to help prevent distortion due to excessive signal levels. All units are equipped with soft-start protection circuits and have power, signal, protection, and clip indicators on the front panel. These amplifiers are fan-cooled with circuit protection and power-on delay. The quad series amplifiers are powered by 100-120VAC or 220-240VAC 50/60Hz (depending on the country's requirements).
