The LLS-2-XLR Line Level Shifter & Hum Eliminator from Ebtech is a handy two-channel utility that effectively provides line level transformation between balanced and unbalanced devices. The Line Level Shifter also contains Ebtech's Hum Eliminator technology for breaking the ground loops that cause 60Hz hum and AC buzz, noise that can occur when making these kinds of connections.
Audiophile quality components and passive design provide a quiet signal path throughout. The unit uses the physics of inductance and impedance matching to increase or decrease the signal voltage without the added noise of active electronics. "Smart" connections automatically distinguish between balanced and unbalanced connections. The unit features both 1/4" TRS phone and XLR inputs and outputs on both channels.
