MLI1 is a line level passive isolation box designed to remove hum and buzz caused by ground loops, as well as to convert unbalanced signals to balanced signals for long cable runs.

Combining premium sound circuitry with durable, roadworthy construction, the MLI1 provides high-quality signal connection solutions for live, broadcast and studio applications.

The Ground Lift switch disconnects the ground from the Input and Output connections which eliminates hum caused by ground loops.
