[. . . ] · Mode selector switch for stereo, parallel and bridged-mono operation Benefits of resonant-switching include: · Outputs - Speakon and five-way binding posts · Ground-lift switch and rear panel circuit breaker · Recessed, stepped attenuators with removable knobs · 16-gauge steel chassis, 14-gauge steel front-panel · 20dB lower noise than conventional switching supplies (and therefore more EMC friendly) · Reduced power component stress for better reliability and efficiency · Behaves like a classic linear supply, but with the added ACL (Active Clip Limiting) prevents speaker damage by providing advantages of minimized size and weight reduction gentle gain reduction when signal approaches the clipping threshSwitching output stage old. To maintain sonic quality along with incorporating the advanIGM (Instantaneous Gain Modulation) monitors speaker loads to tages of a switching output stage, Crest Audio's engineering detect conditions that may overstress output devices. This allows has two years of development time in this new generation Class D amplifier. The multiple rail technology is the key to its safe operation into nominal 2 speaker loads. efficiency and low operating temperature. An additional AUTORAMP gradually increases gain to the attenuator level-set- advantage to this design is the amount of power needed over tings when the amplifier is turned on.
