Greetings for Nashville
Hello!
Good to find you guys on here. My name is Marc, and I've been an electronics and audio fanatic forever. I make a living doing consulting, design, tech support and wiring for recording studios. I've nearly mastered everything in this realm, but once I open something up I'm mostly lost. I've repaired a few things by mostly what I feel is luck, and I'm forever changing out components based on manufacturer support recommendations, but I really don't have a good grasp on it. I hope to begin learning more about this by building a few very simple things and moving it up from there! Being a guitarist I'm probably going to dive into making a few pedals just to get my head wrapped around it.
My starting mission is this, and hopefully someone can point me in the right direction. I got a call from my father who has an audio issue, and basically he has two sources (DVD, Roku/Netflix box), and he's using the TV speakers. The gain coming from the DVD player is sufficient, but the gain coming from Roku is several dB lower (from what he's saying maybe 6 dB or so). I determined the most simple fix was to find some form of inline RCA volume booster for the ROKU. I searched, but I wasn't impressed with what I found, mostly all stuff for car audio. I also found the sampson S-Convert, which I figured out a way to rig it do do what I want-but it still seemed silly to buy something that was designed to do so much more than what I need.
Now, to the point! I need to find some schematics for a device that would work as a variable gain line level booster. I'm thinking radio shack project box, some panel mount rca jacks, a potentiometer.... and after that I'm completely lost. Active? Passive? Opamp?!? As long as I can get some variable gain with a decent amount of boost I'm good to go. Can anyone tell me where to start or where best to repost this?
Thanks!!!!
Marc
