Radial ProMS2 Passive Microphone Splitter with Eclipse ET-MS10 Transformer and 30dB Switchable Pad on Input

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. Harnessing the full potential of an Eclipse ET-MS10 transformer, Radial's passive ProMS2 delivers professional-grade clarity for microphone splitting. Its nickel-laminated core lies at the heart of the ET-MS10 transformer's ultra-low harmonic distortion while suppressing phase shift and removing bandwidth limitations you'd get from budget mic splitters. In fact, we're talking about 115dB of common-mode noise rejection backed by a MuMETAL-shield in one of Radial Engineering's freakishly tough steel enclosures. The ProMS2 rejects RFI, EMI, DC line noise, and ground-loop hum with heroic efficiency. If you're setting up a whole bank of mic splitters, then Sweetwater has what you need. Check out these rackmountable Radial J-Rak chassis.
