Allowing you to send a single microphone or DI signal to up to 3 separate destinations, the ProMS2 Passive Microphone Splitter from Radial Engineering can be used in the studio to send a mic to multiple preamps for auditioning and live to send one source to multiple mixers or to supply a broadcast feed. It is a passive device, therefore requiring no power for operation. The Eclipse ET-MS10 transformer is designed to provide a flat frequency response while its RF filtering helps keep your signal interference free. The device features 14-gauge steel construction to stand up to live use.

High performance Eclipse transformer for optimal signal transfer
Equipped with direct, isolated and auxiliary outputs for 3-way split
May be rack-mounted in the J-Rak for multi-channel use
Rugged 14-gauge steel construction for added durability and shielding

    ProMS2 Passive Microphone Splitter is rated 3.7 out of 5 by 3.
    Rated 5 out of 5 by from Above average transformer While true, as mentioned in the previous review, that there are no thumb locks on the XLR connectors, this is common for many pro stage/studio DI and splitter boxes. I have used this box many times and have never had a connection issue. More importantly, to me, is the quality and size of the transformer. Yes, size matters, because without some iron mass it's easy to saturate the magnetic coupling in the low end. While this unit is the cheap version of the Radial splitter with a Jensen transformer, it is still way ahead of typical low cost splitters. Plus it has an extra output. Very solid for the price.

    Rated 1 out of 5 by from XLR cables wouldn't stay connected I was advised by B&H to purchase this product to split a microphone signal from a DJ at live events. However, when testing it the night before a wedding, I noticed that there is no lock for the XLR cables and if the cable moves even a millimeter, then the audio will stop completely. I had to spend about a minute fiddling with the cables just to get them in the right spot and once I did they sounded fine, but then if the device is even touched it will significantly affect the audio. I tried multiple brand new XLR cables and they all had the same result. I had heard great things about this brand but this device does not seem to be very well made and I would not use it for a live event if there's even a chance that someone might touch even just the top of it.

    Rated 5 out of 5 by from impressive build quality this unit went on tour with me for three months and worked flawlessly. It was used to split and isolate a mic signal for TV broadcasts in sports stadia. A very handy box to have at your disposal
