Clear-Com MT-701 Isolation Box

The MT-701 is an isolation box that reduces hum in Clear-Com Encore partyline systems when multiple grounds are present, electrically isolating ground, power, and signaling between two systems. It can also bridge two Encore partylines together, passing audio and call signals between them.

Its transformer delivers a 6 dB gain improvement over the older MT-1, only one termination is needed between connected systems, and four LEDs report status at a glance. One XLR-3M and one XLR-3F connector sit on a compact housing that draws under 5 mA from the line.
