What I had planned to do was clean and lubricate all elements and go from there.

Actually, the resistive elements were in good shape. So now the knobs are stuck in position and I will have to take it apart again. There is not a whole lot of electronics (IC's, Xistors, etc) in there anyway When I put the plastic lattice back on the PCBs, several of the pot knobs did not seat correctly. Yes it is a complete design nightmare but I figured I would at least try and document the innards and any refurbs that would be done to this mixer. This whole mess is held in place with a plastic lattice, which holds the PCBs down. alesis 1622 service manual, alesis 1622 service manual, alesis 1622 service manual user, alesis 1622 service manual transmission, alesis 1622 service manual pdf, alesis 1622 service manual troubleshooting, alesis 1622 service manual, alesis 1622 mixer service manual.The pot wipers fit inside the front panel and then the PCB is mounted so the wipers sit on the resistive elements. The resistive and switch elements are on the PCB itself. The Monolithic construction looks like it could and has evolved into many problems. I got two 1622's cheap ( now I know why ) and I wanted a schematic, as I try to get for all my gear. At least if people get stuck with this beast there should be some info on it's wierd construction and it's Monolithic PCB construction. I plan on taking pics of the innards and posting them on the web. Good Luck! - SCActually, I have taken it apart. And the guy who used to manage the Mackie service dept is still in business in Tukwila Washington. For a lot less money than I spent on two 1622's, I got a used Mackie SR244VLZ and it does more and does it a lot better. Jump over to Mackie, it's budget crud too, but trust me it's a Cadillac compared to the 1622.

I ended up just kicking myself for ever dropping one dime on an Alesis mixer. I bought one to canniblaize for parts, and the other one had the same problems mine had. You are waaaaaaaaaay better off just finding a second and third and fourth 1622 to buy cheap and cannibalize for parts. ThanksI think you are wasting your time looking for a schematic. Any help with the schematic and other advice about this mixer is appreciated. I'd still like to try and fix this 1622 up and see if I can improve the function, quality and reliability of the mixer. My research into this mixer, shows that it suffers from quality and manufacturing issues. Does anyone know where I can get a schematic. I have emailed several sites that sell schematics and still nothing. They say that they don't have the schematic. To start viewing messages,Alesis was of no use in providing a schematic.
