How do I lengthen priority release time on the 450 Dual Zone Priority Mixer?
Increase the value of the following resistors for the appropriate priority:
Priority 1: R229 and R230 Priority 2: R321 and R322 Priority 3: R141 and R142
The amount of time increases in direct proportion to the amount that you increase the value of R229 and R230. For example, if you double the value of Priority 1’s R229 and R230 (from 536K to 1Meg – O.K., its approximately double), then the length of time for the muting circuit to release and allow signal from the lower priorities will also double (from 2-3 seconds to 4-6 seconds).
