That’swherethismanualcomesin.
• If this is your first pro mixer, flip through
the whole book: you’ll find it full of actual
from-the-streetsengineering tips, aswell
asoperation and installationinstructions.
• Ifyou’reanexperienced,big-bucks

Fast-Track“CAN’TWAIT!”tips
forpeoplewho ignoremanuals
A. To adjust input levels:
1. SetTRIM fully counterclockwise.
2. Set GAIN to unity (twelve o’clock).
3. Pushin the INPUTCH. METERING switch.
4. Feeda normal signalinto a selectedinput.
5. Adjustthat input’sTRIMcontrol sothat
thedisplay on theleftLED strip stays
around0, and nevergoeshigher than +10.
6. RepeatforeachofChannels1–4.
