The mixer has arrived! All channels but 10 are outputting signal, but only 1, 11 and 12 seem to be doing so optimally. The rest are rather quiet.
as I mentioned it needs service. I suspect it needs new gain trims and it'll be fine... did you test the line amps as ell as the mic amps? they're actually separate circuits on a switch, not just padded down, there's even a different impedance load. If the same problem is true for both modes then its the gain pots. If the problems are different then its something else. My brief testing indicated the issues were common to both the mic and line amps before I sold it but that's as far as I went. I decided to shop for a bigger desk instead of pulling my hair out... I don't typically hire repair people, its against my relgiion. I encourage you to do so though.
I do have a few questions.
- What's that white tab thing under effects send 3?
I have no idea, its always been there and I never opened the box to look. Its some sort of stand off but what tis purpose is I can only speculate. I've never seen another ramsa with that
- Are the yellow marks at the gain trims for channels 11 and 12 optimal settings?
they were probably optimal for my purposes in line amp mode for a specific project 15 or 20 years ago I would guess.... or someone's, but I think I drew those on and left them for some reason. Although maybe robert hazard drew them on, all this stuff is ancient history. I usually use grease pencil so maybe they're not my markings. I would defintiely never mark a microphone gain position as its so variable, but I regulary mark things in mixdown if I want to ensure recall beyond what ic an do with a recall sheet
- Why did you send me spare faders? They all seem to be working fine.
I had them and my 400b uses longer throw penny and giles faders, so if one acts up go ahead and swap it, but they were all fine when it left. The pairs are never going to be perfectly balanced but that's pretty typical of these mid grade consoles and even my soundcraft isn't DEAD matched like a higher end piece. I'm trying not to horde spare parts as much as I used to. Its crazy to keep parts for gear you no longer have. Put them in a drawer.
I'm still impressed you got your college to buy you a small mixing desk... I mean, you don't get to keep it, but by the time you graduate you should also be graduating to a bigger desk
