More Info

Portable mic splitting for stage use

The ProMS2 is a mic splitter designed to split a single source to multiple destinations simultaneously without signal degradation or noise. A high quality Eclipse transformer inside provides galvanic isolation to eliminate hum and buzz from ground loops, while delivering a wide frequency response and low distortion. Ground lifts on the outputs help further reduce noise, while an input pad allows line-level sources to be connected as well. The ProMS2 can be rack mounted for touring and installation purposes, with up to eight fitting in the Radial J-Rak.
