Simply plug in a balanced XLR signal into the unit's XLR input jack to get started. From there, the signal will be protected by a variety of different features, such as the 14-gauge steel casing to provide shielding against magnetic fields, as well as the transformer-isolated outputs. Each XLR output has its own ground lift switch to help exterminate hum or buzz from ground loops. On the side of the unit, a trim pot allows any broadcast technician to easily reduce output level across all 14 connections. An XLR loop-through allows you to daisy-chain the signal to additional units, while bumpers on the side protect the aforementioned throughput and the input. Rubber feet keep your floor scuff-free, and a steel handle allows for quick maneuverability and transport.
