INPUT PANEL 1. XLR INPUT for balanced, low-impedance, +4dB line-level signals. 2. Ground lift disconnects the signal ground to eliminate buzz and hum caused by ground loops. 3. Secondary Ground Lift used for instances where two separate devices are connected to the outputs. -
Page 3: Ground Lift
A major benefit of using transformers is the elimination of noise caused by ground loops. The transformer isolates the devices connected to it by decoupling the signal ground between the input and output. This isolation effectively breaks ground loops between devices and blocks hum and buzz. GROUND LIFT To make grounding as flexible as possible, both units feature a ground LIFT switch. -
