Ebtech 2 Channel Line Level Shifter demo

What do you do when you need to connect a low volume -10 dBV output device (like a keyboard, CD player or DJ mixer) to a high volume +4dBu input (like a pro mixer or a power amp)?

The 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 ground-loops that cause AC hum.
