ABSTRACT:
A voice over circuitry comprises a comparator for comparing a fader signal to a predetermined threshold level which may be determined during a rehearsal. The output of the comparator is connected to a two part display. When the fader signal is greater than the threshold level, the first part of the display is activated and when the fader level is less than the threshold level the second part of the display is activated. Neither of the two parts of the display are activated when the fader signal equals the threshold level. Based on the state of the display, the fader signal is adjusted as necessary to equal the threshold level. Thus, the mixing fader may be set quickly, accurately and consistently to the desired depth of fade during a mixing session.
