Crest Audio Pro Series 4801 Power Amplifier

Crest 4801 Professional Power Amplifier. The Crest Audio Model 4801 is a compact, high-power amplifier designed to meet the most stringent demands of professional use in concert touring, studio monitoring, high-quality sound reinforcement, and professional installations. A forced-air configuration is used to cool channel heat sinks mounted in a back-to-back tunnel arrangement. An actively balanced female XLR input connection, Octal Socket, and 5-way output binding posts are provided for each channel. The 4801 is fully compatible in design with other Crest Audio Professional Series amplifiers, Octal Socket Accessories, and the NexSys® computer-controlled audio system.

High thermal mass heat sinks. 5-way output binding post connectors. Stereo/Parallel/Bridged Mono mode selector switch. Rear panel ground lift jumper. Clip Limiting prevents speaker damage with gentle gain reduction at clip threshold.

IGM (Instantaneous Gain Modulation) monitors connected loads to detect conditions that may overstress output devices, allowing safe operation into nominal 2O impedances. AutoRamp gradually increases gain to attenuator setting level when amplifier is turned on. Other protection circuitry: comprehensive thermal management, and short circuit, DC voltage, turn-on/off transient, current inrush and sub/ultrasonic input protection. Ultra-strong, single piece steel chassis.
