Meter
The meter can show the Music System Threshold Input level or the amount of NOM
Gain Limiting. Clicking the title button toggles between them.
NOM Gain Limit
This field controls the NOM (Number-of-Open-Mics) Gain Limit. Enter a new value
from 1 to 10 (default = 1).
Music System Threshold Input Channel
For each Group, click the music thresh input ch. button to select the channel or Matrix
Mix Bus from which the Music System in this group derives its threshold.
Music System Threshold Input Level
The music system threshold fader sets the input level for this group’s Music System
threshold. It acts as a master threshold for all music mode channels in the group. The
LED indicates signal presence or overload.
Auto Mix Depth
This control sets the maximum amount of attenuation applied by the Music System.
The default setting is -15 dB.
Setting up the Music System
The Music System can be used to duck mics not in use by comparing them to an
ambient sensing mic.
The Music System can also be used to duck the audience mics when the people on
stage talk, preventing PA bleed into the mix. Use a submix of the stage vocal channels
(post-Dugan) to supply this threshold signal instead of a sensing mic. A Model E-2A
mix bus could be used to create this threshold signal.
Some channels can be set to the Music System while others are in the Speech System.
Unlike the Speech System, the Music System channels should be patched post-EQ,
pre-fader so that fader and threshold adjustments remain independent.
To set up the Music System, you can:
•Send a music system threshold signal from the console to any available input to
be used as the Music System Threshold Input of a Dugan group.
- OR -
• Use a Matrix Mix Bus as a source.
