Video and Audio distribution amplifiers allow you to output the same
audio and/or video signal to mulitple devices without losing quality.
Splitting signals typically reduces a signal strength by 3-5Db. Using
an amplifier solves this problem. You can output the the signal to up
to 4 devices and keep the same quality as if you were outputting it to
one. This amplifier accepts 1 video and 2 audio inputs (either 2 mono
signals or 1 stereo) and has 4 outputs for those same signals.
