Crest Audio Pro 7200
The Crest Audio Pro 7200 3300W Professional Stereo Power Amplifier designed to achieve unsurpassed sonic performance and long-term reliability under extreme stress in touring or fixed installation applications. Absolute sonic accuracy is the hallmark of every Crest amplifier. Bass is solid and defined to the limits of audibility with ample current reserves.
Wide-bandwidth output devices ensure detailed, transparent high frequency response. And, thanks to Crest's exclusive IGM circuit, the Pro 200 Series will drive 2ohms loads safely without compromising performance. The ACL (Active Clip Limiting) prevents speaker damage by providing gentle gain reduction when the signal approaches the clipping threshold. IGM (Instantaneous Gain Modulation) monitors speaker loads to detect conditions that may overstress output devices.
This allows safe operation into nominal 2ohms speaker loads. AUTORAMP gradually increases gain to the attenuator level settings when the amplifier is turned on. This prevents abrupt turn-on level. Other protection features include short circuit, DC voltage, comprehensive thermal management and current in-rush turn-on/off; transient sub-sonic input.
