Radial Engineering ProMS2

Radial Engineering's ProMS2 is a 2-way balanced passive microphone splitter made to split and send an audio signal to up to 3 different destinations simultaneously on stage or in the studio. It has one transformer-isolated output and two direct outputs, -30db Attenuation Pad and Ground Lift.

Notable features

• Sends one microphone signal to three destinations simultaneously
• Eclipse transformer for clean, transparent audio
• Eliminates hum and buzz caused by ground loops
• Single isolated output provides optimal noise rejection

Portable Stage Microphone Splitter

ProMS2 is a microphone 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 offering wide frequency response and low distortion. Ground lifts on the outputs help further reduce noise, while an input pad also allows line-level sources to be connected. The ProMS2 can be rack-mounted for touring and installation purposes, with up to eight fittings in the Radial J-Rak.

Practical Applications of ProMS2

Using ProMS2 for a 2-way Microphone Split

Radial ProMS2 is the ideal interface for splitting a microphone signal and connecting it to multiple mixers simultaneously. The 100% isolation eliminates potential ground loops between the two mixers for a truly silent performance, while the main output provides 48V phantom power to the microphone.

Using ProMS2 for a 3-way microphone split

Sometimes it is necessary to send the same signal simultaneously to the main mixer, stage monitors, and a recorder. By connecting the source microphone to the XLR input of ProMS2, the direct output with phantom power is sent to the Main Mixer, the direct output with Ground Lift to the Stage Monitor Mixer, and the isolated output to the recording system.

Using ProMS2 to compare two mic preamps

In the studio it is often advantageous to compare the sound of two microphone preamplifiers on a particular vocal, instrument, or amplifier. ProMS2 makes it easy to compare these devices. Simply connect the ProMS2 microphone and then split the signal by sending it to the two preamplifiers and then record with whichever one you prefer.
