(Moved to Gen. Discussion) Help with analog VU meters

Post by ModRob » Fri Nov 01, 2013 6:14 pm

Added to General Discussion but can't figure out how to delete this post...sorry...



Moved past one hurdle, now onto I hope a bit easier ground...
Using an old mixer, and a consumer cd deck input to it. The -10 level will barely move the VU needles when plugged directly to the meters, so when I input to the console, the meter activity is near nothing. Routing is pretty simple now; through wiring, switches, Shallco channel attenuator pot, to a bus, then to the master volume pot. Then out to feed an outboard stereo amplifier. Also, the stereo amp has to be potted up quite a bit more then when listening to other sources (sound still clean though).
So, is there a cheap, down-and-dirty circuit/thingamabob/device I can install to ramp up the level to drive the meters better?

Thanks much for any ideas...

maybe something simple such as a LM324/741 opamp running as a pre-amp? There's a tons of schematics for those scattered around everywhere.
