This Alesis MultiMix 8 USB 2.0 FX mixer/audio interface has worked well for me over the years in my home studio, but lately the switches were noisy and would take some time to try to get working right. Dust and grime had seeped into the switches and pots and they were dirty on the inside. I finally had enough of it, so I decided to tear it open and clean everything. Here’s a few pictures on my adventure:
Before
Knobs removed, some bits of tape (2, 5/6, 7/8 and Main) must’ve been used to hold loose knobs
Removing nuts on 1/4″ connectors
Knobs, nuts and washers removed
Side caps removed, bits of tape removed
After opening case, see the connectors to be removed – all except the black power cable
Main board out, set on paper towels, outside for ventilation of fumes…from:
QD Electronic Cleaner to the rescue…use the long tube to spray in the openings on the sides of the potentiometers and through the tops of the push switches, then exercise each one. I used this video as a reference.
All back together minus the side caps…tested it and it works! No more noisy, finicky switches and crackly noises when I turn the knobs.
Spare parts. These side caps had some sort of coating that became gummy over the years. I tried using the QD cleaner to no avail, then I started sanding one and decided it just was not worth the effort. All these do it cover the edges of the metal especially over the top edge mainly for aesthetic purposes…so off they go!
