Dx8 – 24 compress • ratio: this determines the change in output level as a function of the change in input level, once the threshold has been exceeded. It is calibrated in decibels, with a range from 1:1 (off) to 20:1. Thus, if it is set to 10:1, an increase in input level of 10 db (assuming the inp...
Dx8 – 25 each individual channel is attenuated by an amount, in db, equal to the difference, in db, between that channel’s level and the sum of all the channel levels. This keeps the overall system gain constant, and allows the system to deliver maximum acoustic gain without feedback. There are thre...
Dx8 – 26 use a control group to adjust the volume of two or more channels at the same time. All faders that are assigned to a control group will have their gain settings modified by the amount the control group fader is increased or decreased. For example, a control group might be used to adjust the...
