EV Electrovoice DC One Speaker Management System

Based on a two-in, six-out topology, the Electro Voice DC-One at the Academy of Sound is designed primarily for users of small-to-medium sized sound systems in both mobile and installed applications.

 While the unit is an all-new development based on a powerful SHARC processor, it is 100 percent compatible with all settings from other Electro-Voice signal processors, including the Dx38—the best choice for achieving maximum performance with an EV loudspeaker system. 

A large part of DC-One’s development was aimed at ensuring that users can easily handle its serious digital horsepower and high-end audio performance. Though free PC-Editor software is available, the DC-One can be easily operated via the front panel. Direct access buttons, six predefined configuration modes (one being free configuration), straightforward output delay settings, and true professional metering all allow for safe operation. 

DC-One's unique "front-panel access control" allows the user to select a personal library of accessible presets (out of 60 factory and 20 user presets). In addition, the user can determine which individual parameters in each preset are locked (e.g. factory predefined output parameters) or editable (e.g. master EQ or delay settings). 

The DC-One has a 19-inch chassis that is deep enough to match typical amplifier depths, a front panel USB connector for the PC-Editor, and accepts either analogue or digital (AES-EBU) input signals; a six-dB input pad is available. The RS232 on the rear also provides eight contact closures for preset changes, or allows two units to be linked for larger systems. The PC-Editor software, as well as firmware updates allowing additional functions, will be available on www.electrovoice.com
