Ebtech 2 Channel Line Level Shifter XLR
The LLS2 Line Level Shifter uses the physics of inductance and impedance matching to increase or decrease the signal voltage without the added noise of active electronics. The Line Level Shifter also converts back and forth between balanced and unbalanced signals automatically. This is great because most -10dBV signals are unbalanced, while most +4dBu signals are balanced. It also contains Hum Eliminator technology to prevent groundloops that cause AC hum.
