cheapest way to get from line level to modular level

Post by lilnoah95 » Sat Nov 02, 2019 6:21 pm

I'm interested in processing external sounds in euro, but currently don't have any way of boosting the signal high enough. What's the cheapest way to make things loud? I'm looking for a super affordable DIY module or schematic that a beginner could read and build. thanks

The ARP 2600 preamp is a decent circuit

That may be true, but the OP was after an affordable DIY module. You could try the Barton input module, which is a simple PCB only, so you can / will need to work out your own front panel. It has been discussed here before, so look for that to read user comments. Searching for "DIY modular synth input" should find you some other options.

I use a CGS Stomp adaptor for that...

The AI006 would do it in 2HP.
Pretty affordable $10-70.

What about the ARP 2600 circuit doesn’t meet their criteria? It’s very simple, no rare parts (LM301 went out of production about a year ago but is still available and easily replaced pin-for-pin with a TL071), easy-to-read schematic... Should be a perfectly doable DIY circuit for most beginners.

Damn AV500! I have one exactly like it (except my panel is aluminum and there's 1/4" jacks on the in's)

Yes, just that circuit in the middle. You May want to do a google search for “TTSH schematics” as well. They’re the same as the 2600 schematics but they’ve been transcribed and I find them a little easier to read than the original hand-written diagrams.

I like this circuit because it’s simple but versatile. Being able to switch between three different gain levels is really handy. And it makes for a pretty decent distortion effect too. ;)

Maybe add a follower as well while you're at it
I regret not adding that (plus no space now)
