By PSW Staff • November 3, 2015 Radial Engineering announces the mPress, a new press audio distribution system that offers nearly unlimited expansion without signal degradation or noise. According to Radial senior engineer Dan Fraser: “The traditional press box has always been presented as a suitcase with a mic input and a host of mic outputs.In the past, transformers performed the task of splitting the signal and providing isolation against hum and buzz caused by ground loops.” “In recent years, the use of active signal buffers has replaced the transformer as a means to cut manufacturing costs. Unfortunately, this has resulted in noise creeping back into the audio system, deteriorating the audio quality. The mPress solves the problem by combining an active drive circuit with a host of transformer-isolated floor boxes called Exo-Pods. This modular approach allows the system technician to distribute Exo-Pods throughout the press gallery while assuring each member of the press receives a clean, hum-free signal. To ensure no digital trickery is at hand, the mPress is 100% analog.” The mPress is configured in two parts with a master host – the mPress – and a series of external slaves called Exo-Pods. The mPress is housed in a standard 1RU 19-inch rack enclosure and begins with two mic inputs, both of which are equipped with a variable level control high-pass filter to eliminate excessive resonance and tame the proximity effect. For podium mics, 48V phantom power is available and activated using a front panel switch. This is recessed to prevent accidental use. Selecting between the mic channels is done using front panel switches. In order to control ballistics from overly excited orators, the mPress has been outfitted with an easy to use single-knob limiter. To accommodate ‘walk-in’ music, the mPress is equipped with ¼-inch, RCA and 3.5mm stereo inputs along with a separate level control. This enables the mPress to be connected to a couple of powered speakers via the main stereo XLR outputs to provide background entertainment while the gallery waits for the ‘talent’ to arrive. A headphone output on the front panel is available for local monitoring and trouble shooting. There are eight specially designed balanced outputs, with two on the front panel, and six on the rear. Each of these may be configured using a recessed switch for mic level or high output drive to feed an Exo-Pod. This allows the mPress to be used as a 2×8 distro for smaller events or expanded by adding Exo-Pods on the outputs. The Exo-Pod is a passive floor box that features an XLR input, a throughput for expansion, a local level control plus ten XLR mic outputs and four 3.5mm mini TRS outs for those who are equipped with a mini recorder. A test tone may be activated to set local and master levels. With the use of eight Exo-Pods, one can distribute the signal to as many as 112 users. This can be further expanded using the throughputs by simply adding more Exo-Pods. Power is only needed at the main mPress box and is supplied via an external lock supply that will accept any input from 100 to 240 volts. The mPress will be available in January 2016. Pricing is estimated at $1,500 USD for the main unit and $250 USD for each Exo-Pod module. Radial Engineering Comments Have something to say about this PSW content? Leave a comment!
