Dust will settle in the fader track overtime dust can cause a popping no\
ise on the fader. To prevent 
this cover you mixer. If the mixer has been unused for over a month or more move you faders up and 
down a couple of times this will move most of the settle dust from the fader track. Do not eat, drink, 
or smoke over you over or near the mixer.
Don’t use spray cleaners. Use compressed air or a vacuum with a brush accessory.
Cleaning frequency depends on the environment in which the mixer operates (i.e. smoke, fog residue,
