I'm switching audio signals (line level) with a solid state relay board (Keyes - 8x Q3MB-202P), but when I switch off one channel, it takes some milliseconds (maybe around 500ms to 2 seconds) to really stop the signal flow. I believe this happens due to either a capacitor or an inductor (I think it's an inductor) that's in the board, so I was wondering if I could remove (unsolder) one of these components from the board and make the switching off more precise.
I don't have an individual piece of a Q3MB-202P, but I believe this wouldn't happen with the individual piece. This is probably caused by the board circuitry, which does that for integrating LEDs or for some safety reasons which I don't mind sacrificing. I couldn't find a schematics of this board, but probably someone will know by the picture.
Attached are pictures of the board. What I have referred as inductor is the green piece (F), but I'm not sure if I'm right. In this piece it's also written 2A (or 2AE, it's not very legible).
Note 1: the reason I'm switching signals with Solid State Relays is because I need low resistance. I'm avoiding using a IC (like 4066) as it has too much resistance for my audio signals and then the sound is too quiet.
Note 2: I don't want to use a mechanical relay to avoid the click noise.
Note 3: I don't have individual pieces of Solid State Relays (Q3MB-202P) and I don't have the time to buy them now. I need to sort out this problem quickly for a project as the deadline is in 3 days.
I really appreciate any help!!! Thanks!
