mPress™ Specifications

The Radial mPress is a full feature balanced distribution amplifier for press conferences and public announcement systems. Two mic pre amps with +48V phantom power and threshold limiter ensures quality audio without clipping. Useful level controls are employed for program material, main L-R outputs and headphones for monitoring. The high level gallery outputs may feed the Exo-Pod expander units or be switched to LOW for feeding other external preamps or mixing consoles.
