Small Fader CAL?
« on: March 19, 2018, 11:32:53 PM »
Hey guys,

Got a few small faders that have to be pushed up about 5db to hit unity. Thinking it may just be bad fader tracks or wipers. Also not sure if any of the trim pots on the group amp cards may CAL the signal going to the small fader?

Just looking for some advice.

Thanks,

Josh

It'd be kinda unusual, but not impossible, tat the fader s are bad. What happens when the small faders are routed to the mix bus; do the levels match then?

Hey,

Thanks for the feedback Chris.

Yeah, when the small faders are routed to the mix bus the levels still don't match.

Some need to be raised higher than others to reach unity & vice versa.

I'm assuming that if all the small faders are pushed to maximum there's still an inbalance. If so, it's as if the faders don't exist, and therefore any error in taper doesn't really matter. Have you gone through the calibration procedure? Had the console been recapped? You may want to check the levels in (pin 38) and out (pin 41) of the small fader buffer on the Group Amplifier card.

Also, we just recapped our console 2 months ago & we've gone through and calibrated the whole console.

We'll, be checking pin 38 & 41 next.

Again, really appreciate the help!

Hey Josh

Did you figure this out?
