The MSX 48 is a totally passive device requiring no power, and consists of 16 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 suitable for use with a remote recording truck or TV feed. Duplicates of the monitor and aux splits are also provided on two sets of dual 25-pin D connectors on the rear panel, wired to Tascam wiring protocol.
