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.
Features

    * 2 Channels
    * Converts back and forth -10dBV and +4dBu.
    * Automatic balanced /unbalanced conversion.
    * 1/4"TRS 'smart jacks' input & outputs.
    * Built-in Hum Eliminator technology prevents ground-loops eliminating AC hum & noise.
    * Automatically translates signal voltages to match differences in ground potentials, avoiding clipping.
    * Audiophile quality components assures the best noise and distortion free performance.
    * Frequencs response 10Hz to 40kHz +/-1dB into a 10kOhm load
    * Distortion less than 0.002%THD @ 1kHz
    * Crosstalk better than -97dB
    * 2 Year Warranty
    * EBTECH quality and reliability
    * Made in the U.S.A.

Also available in a 8 channel version.

Almost all AC hum (60Hz in the US) is caused by ground-loops. Rather than filtering, the HUM ELIMINATOR prevents ground-loops from forming in the first place. Just plug the HUM ELIMINATOR into the signal lines between offending pieces of equipment and you're done. Quick and easy... Has two channels

It also is available in a 8 channel rack version.

The MB15 ProMatch converts consumer level stereo RCA signals to balanced XLR professional line level, and back. One side of the unit, labeled 1, has two XLR inputs and stereo RCA outputs. The other side labeled 2, has stereo RCA inputs and two XLR outputs. Each side has stereo level controls, and an LED indicates that power is applied to the unit. An additional benefit of the MB15 is that it will act as a balanced XLR line level control. By adding a stereo pair jumper between the four RCA jacks (connecting ins to outs), the two Level controls may be inserted into any balanced XLR line.
