The MSC-U module contains a transformer isolated jack (600 ohm) for interfacing a tape recorder into an existing sound system for recording purposes. The MSC-U ouputs a balanced mono line level signal from a sound system for a tape recorder. The module mounts into a standard electrical box (not provided), and is finished off with a matching decora coverplate. Connections on the backside of the module are made via a 3-pin euro style connector. The MSC-U module is available in brown, ivory or white.
