    Modded Behringer Powerplay IEM (build report, DIY)

    After some experiments I ran into the question "Why cant the P1 (in my design from April 9th) be used as a stereo Practice amp?" and so I did some test! I've disconnected the connector board and built the schematic as shown beneath. Basically the buffered bass is passively mixed with the...

    If anyone wondered if Fredde's design would fit onthe single XLR connector board, here's the answer: it fits! This way you would free up the space for a battery. Not that that would be very useful because the connector board is not powered by the battery. So I took the liberty to change some...

    I'm pretty sure the problem is in the Behringer board, thank for your thoughts though! Decoupling caps might help the bass signal, which value would you suggest? Couple of pFs right? I've sent my designs to Seeed studio. Their PCB printing service is called Fusion. Its not the highest quality...

    Sure, pictures below! I made some changes after I made this, because I switched the left and right channel, and I made some improvements. I'm not planning to make a commercial product out of it and I'm not in the business of etching. Its just a hobby and these days its so cheap to get a...

    I'd be happy to make a board for you! We just have to work out what you'd exactly want. Hit me up if you're interested. So, a while ago I built the device without the direct send and it works great! Below are some pictures :D Sadly, I have a loud (I mean ear deafening) pop when I power-on the...

    Indeed, for recording I wouldn't use the bass signal via the cable, only the belt pack as headphone amp. I finally had some time to test one thing and another. I used a 4 meter (13 ft) 4 wire + shield cable, bass signal was wire + shield, stereo headphone signal was 3 wires. The bass jack...

    Modded Behringer Powerplay IEM (build report, DIY)

    Seems reasonable! The benefits of stereo live on stage are minimal aswell.. I do indeed mean that they share the same shield. Thanks for clarifying the difference between shield and ground and why the problem here is the conductors being close togther inside the same shield. The dual XLR might...

    Fredde, thanks alot for this! I was just looking for about the same solution and this fits my needs! Though, I don't need the 'Bass to IEM' - signal but I would like a stereo feed for my headphones. Since my requirements are a tiny bit different I have a question about crosstalk. I did some...
