Introduction

Quest QA Series power amplifies are built to work hard inthe 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, noteasy manufacture.

A minimum of disassembly is required for testing and maintenance meaning lower operating costs and longer amplifier life.

Features

  • Input Stage:
    • Pro active protection senses stages of system function to safeguard your investment both on turn on and while under operation.
    • Silent switch on/off circuitry reduces potential speaker damage in the event of intermittent power.
  • Power supply:
    • The high current power supply is manufactured to function reliably at high temperatures and well exceeds industry standards.
    • This results in smooth bass response and considerable dynamic headroom.
  • Industrial Spec
    • Fans: Dual heavy duty cooling fans guarantee long life of all electronic components.
  • Input Connection:
    • XLR parallel male and female input connections calibrated for most pro spec system controllers and electronic cross-overs. features
  • Speakon Connections:
    • International AES standard Speakon connectors wired for two channel and Bridge mono operation simplify speaker connections.
  • Limiter:
    • A switchable high speed limiter acts as a final speaker protection but can be disconnected where sensing speaker system controllers are required.
  • Built in switchable X-overs:
    • High Amplification and low pass filters on each channel make the versatile QA series even more flexible witha sub-mid/high frequency dividing network.
  • Selectable Gain settings:
    • Adjustable input switching for 0.775V, 32 dB or 26dB make system calibration easy.
  • Easy access air filters:
    • User serviceable air filters are easy to maintain for trouble free operation.

Note The QA Series Power Amplifiers are not Bridgeable
