Crest Audio (InfoComm 2005, Las Vegas, June 8-11, 2005, booth #1964) announced its new Nx CobraNet-8™ control module and CMi Series power amplifiers, which work to support Crest NexSys 4 and Peavey MediaMatrix MWare software programs for advanced control and audio routing. The Nx CobraNet-8 module and CMi power amps will be available in 2005.

The Nx CobraNet-8 module, which fits into the rear bay of CMi 2204 and CMi 2208 power amps, supports all NexSys functions, DSP functions and CobraNet digital audio I/O on a single Cat-5 Ethernet cable. A four-character LED allows easy setup, control and monitoring of up to eight CobraNet audio channels from the rear panel of the CMi power amps, which ship network-ready.

An extensive suite of DSP options—delay, EQ, compression/limiting and crossover—adds to the functionality of the Nx CobraNet-8 module. Amplifier monitoring includes ACL, IGM, I/O gain (VU), DC, thermal protect, fault, mute, Ethernet data and link statuses.

The 4-channel CMi 2204 and 8-channel CMi 2208 power amps feature an advanced amplification architecture that allows low impedance or 70-volt operation at the same power levels. Each amplifier in the chassis will operate to rated power, regardless of impedance connected, from 4 ohms to 70-volt line systems. The design centers on an ultrahigh-efficiency output circuit, lowering the line current required for a given output power by as much as 50 percent. All inputs and outputs are on Phoenix connectors with level controls in the rear. In addition, a control voltage input is included on each channel to allow external gain control, while the fault output on each channel allows the CMi power amps to be wired to other monitoring systems.

Crest Audio's exclusive ACL (Active Clip Limiting) automatically reduces gain at the onset of clipping to prevent amplifier and load damage, while IGM (Instantaneous Gain Modulation) monitors load current to protect against overloading. When used with the external Crest Audio CMX accessory, CMi power amps will also support 100V and 50V operation. Both the Nx CobraNet-8 module and the CMi 2204 and 2208 are backed by Crest Audio's five-year warranty.
