The Audio/Video Distribution Amplifier


With the amount of equipment in home
entertainment centers today the need to be able to vary the gain of the
audio or video signal is needed. I found this particular circuit helpful
when used in conjunction with the Universal Descrambler and a
Stabilizer circuit I built for making copies of video tapes. It not only
allowed me the ability to fine tune the video strength it also helped
me increase the recorded audio which typically becomes poor when making
tape copies. Circuit operation is straight forward for amplifier
circuits. The second channel for the audio amplifier is made up of the
same components except the other half of IC1 is used. Pin 6 & 5 are
inputs and 7 is the output.
