  • Quest QA 3004 Stereo Power Amplifier Details

    The Quest QA3004 amplifier has been designed and engineered to a standard not only more than adequate for any demanding installation, it will handle a touring environment with military endurance.

    As with all Quest Engineering products it's not looks alone, the design emphasis is on good sonic performance and long life span under professional conditions.

    • Input Stage - Parallel XLR inputs and low noise gain stage, 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
    • 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 Switch-able X-overs - High and low pass filters on each channel make the versatile QA series even more flexible with a sub-mid/high frequency dividing network
    • Selectable Gain Settings - Adjustable input switching for 1.4V, 32 dB or 26 dB make system calibration easy
    • Easy Access Air Filters - User serviceable air filters are easy to maintain for trouble free operation.
    • Built to Last - Heavy gauge welded steel chassis with vibration proof fittings and an emphasis on over engineering guarantees years of trouble free service in demanding environments.
