QUEST QA3004 เพาเวอร์แอมป์
Quest QA Series power amplifies 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.
