The ARX MSX 12 Transformer isolated Microphone/Line Splitter has been developed to deliver noise-free audio splitting with minimal setup time. Its intuitive layout and clear, uncluttered labelling enables a quick and easy solution to the increasing complexity of today's standards of audio production.

The MSX 12 is a totally passive device requiring no power, and consists of four channels of transformer isolated ultra low noise Microphone/Line Splitter. Each of these channels has a direct looped Main/FOH feed, and a transformer isolated Monitor split on the front panel.

On the rear panel is an Auxiliary transformer isolated split ideal for use with a remote recording truck or TV feed.

Marker panels on the front provide a space where individual channel connections can be noted.

The all-steel chassis of the MSX 12 provides strong interference resistant shielding. Internally, state-of-the-art transformers deliver superb audio quality and total galvanic isolation.

The MSX 12 is the easy answer to multi channel signal splitting requirements.
