The Radial mPress is a modular press box that can be expanded as needed to feed a community-sized press gallery or distribute audio for an international event.
The design begins with the mPress, a master head distribution amplifier that is equipped with two microphone inputs, 48V phantom power for condenser microphones and a built-in limiter to prevent overload from overly rambunctious orators. Eight balanced mic outputs may be used to supply feeds to a small press gathering. For larger system requirements, a series of modular Exo-Pods may be deployed. These external modules are connected using standard mic cables and feature ten balanced mic outputs and four mini 3.5mm TRS connections to feed portable recorders or hand-held video cameras. In order to eliminate hum and buzz caused by ground loops, stray DC currents and less than ideal powering systems, all outputs are transformer isolated.
The mPress’s modular approach replaces the spaghetti of cables that usually hampers setups with an orderly system than enables one to create zones for various groups. From each of the mPress XLR outputs as many as four Exo-Pods may be chained together, for a total of 320 microphone and 128 recorder outputs. A built-in 1kHz test tone provides everyone with a reference level and the built-in headphone amplifier helps when trouble shooting. To simplify setups, a main stereo output is available to feed a pair of powered speakers and broadcast the event to an audience. Separate audio inputs also enable the mPress to play background music while waiting for the guest speaker to appear.
The mPress… a modular press box designed to grow to suit your needs.
