Pre-amp at its most basic
« on: 9 Mar 2003, 08:59 pm »
I was exchanging pm's with another circle member as to the various functions of a pre-amp.  The following link shows a pre-amp at its most basic--just a pair of RCA inputs wired to two mono volume controls  wired to a pair of output RCA jacks. Would work with just one input and give volume control and balance.  I tried to explain this, but sometimes the picture is worth more.

How's this for basic:  A silver bullet plug with two resistors, some wire and a copper jack.

I used a series 22K and a parallel 2.0K ohm for my listening volume.  Your resistors may be different - just increase the 22K for lower volume.
