Momentum Digtal Snake System

The Momentum digital snake system by Pro Co is designed to replace traditional analog audio wiring anywhere audio distribution is needed. By capturing audio at the source, converting it to digital audio and distributing it over a standard Ethernet network, many of the difficulties in executing the increasingly complicated audio systems of today can be simplified. By reducing the amount of field terminations, installation becomes less time consuming. Texas Instrument, Burr Brown mic preamps and Cirrus Logic digital converters provide a platform that is as close to analog as possible without the inherent problems that are associated with traditional wiring.

Flexibility and expandability are enhanced through the use of eight channel modules for both inputs and outputs. Signal routing becomes as easy as clicking a button. You can place inputs and outputs anywhere the network. Also digital interfaces will be available for seamless system integration into many of the major brand formats.

New for Momentum, a matrix mix engine output unit for use as a personal monitor system or distributed audio mixer capable of 4 stereo or eight mono mixes using any 32 inputs that are available on the momentum network.
