QA 4004 power amplifiers are built to work hard in the tough environment of pro audio. Industrial spec multi-speed fans and generous heat sinks will keep the output stage cool even if the amplifier is installed in a dusty and poorly ventilated area. Service and maintenance is easy as the internal architecture is laid out for easy access by a qualified technician. The sonically superior output stage is composed of a generous abundance of output devices for greater electronic stability and sonic fidelity. QA series amplifiers are manufactured to a standard accepted as desirable practice for a concert standard power amplifier. Heavy gauge welded 16-gauge steel chassis with vibration proof fittings, and an emphasis on over-engineering, guarantees years of trouble-free service in the most demanding environments. Quest set about a design and layout for easy service, not easy manufacture. A minimum of disassembly is required for testing and maintenance meaning lower operating costs and longer amplifier life.
Parallel XLR inputs and low noise gain stage, silent switch on/off circuitry reduces potential speaker damage
High current power supply is manufactured to function reliably at high temperatures
Dual heavy duty cooling fans guarantee long life of all electronic components
International AES standard Speakon connectors wired for two channel and Bridge mono operation
Switchable high speed limiter acts as final speaker protection
High and low pass filters on each channel make versatile QA series even more flexible with sub-mid/high frequency dividing network
Adjustable input switching for 1.4V, 32 dB or 26 dB make system calibration easy
User serviceable air filters are easy to maintain for trouble free operation
