The MSC-A has a transformer isolated RCA jack and 3.5mm jack for converting an unbalanced mono line to balanced mono line in a single-gang decora module. The MSC-A provides an easy way to input mono audio signals from a variety of audio devices into an existing sound system. The module mounts into a standard electrical box (not provided), and is finished off with a matching decora coverplate (see HPS series). Connections on the backside of the module are made via a 3-pin euro style terminal. The MSC-A module is available in brown, ivory or white.
