Stereo in/multiple Stereo outs Circuit

MartinByrne · 6th May 2009, 05:30 PM

Hi,

I'm looking for a circuit that can take one stereo input line level, and can output 2 or 3 stereo outputs of the same signal. Instead of using a splitter cable

For instance preamp out from a car stereo or even a small mixing desk into 2 or 3 amplifiers.

Thanks,

Martin.

I believe what you want to build is commonly called a "distribution amplifier".

This one has passive output splitting.....

And this one has active buffered output splitting.....

Hi,

Thats exactly what I want to build, I didnt know it was called a distribution amplifier...I could'nt find any circuits myself, but it helps to know the name of the type of circuit you want to build!

Many Thanks

Martin.

I have a audio authority model 985. Like this; http://cgi.ebay.com/Audio-Authority-...parms=72%3A570|66%3A2|65%3A12|39%3A1|240%3A1318|301%3A1|293%3A1| 294%3A50

I was using this to turn 1 set of preouts into 8 sets of preouts. It worked just fine. no distortion, and you can add 10 or more of these units in line to create even more jacks if you need.

I picked mine up for 4 bucks if i remember right at a thrift store, but $20 is worth it. It also transfers RCA video.

Also I should note mine says 'studio grade quality', noise cancelling, balanced inputs, ultra-wide bandwidth.

I havn't noticed no difference with it in-or-out of line.
