Amp project question...
« on: February 17, 2019, 05:32:36 AM »
Gudday all,

I'm doing another stupid pedal trick, by putting a TPA3116 D2 power amp into an enclosure with a JC120 pre on vero.

The exact board I have is here: 
https://www.ebay.com.au/itm/DC-12V-24V-TPA3116-D2-100W-Mono-Channel-Digital-Audio-Power-Amplifier-Board-O9C1/183298033734?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649

and there's a review of it here:

I'm using the JC120 pre layout as attached.

My the JC is working @ 33v, and it's easy enough to get 24v to the power amp, but my question is this:  Do I need to bring the level from the JC up before it goes to the amp? I know I could just suck it and see, but does it need to come up to line level first?

Any ideas, suggestions, or ridiculing is welcome.

Willy.
