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.
