Controlling Ambience
Unlike the Speech System, the Music System does not maintain constant ambience.
To smooth out the ambience, two methods can be used separately or together:
•
The
last hold
function keeps the last mic on that stays above -3 dB gain for
0.5 seconds. When another mic passes the same criteria, it becomes the
last
hold
mic.
To activate the
last hold
function for a group, click that group’s
last hold
button.
•
Raise the
auto mix depth
control until you do not hear an objectionable shift
in ambience. Just a few dB of attenuation may suffice to reduce bleed or
feedback.
Gain Limiting
Gain Limiting and the Music System
NOTE:
See Chapter 2:Theory of the Speech and Music Systems.
The Dugan’s unique implementation lets you set the number of mics allowed at full
gain before gain limiting occurs. This can prevent feedback as the Music System turns
on more mics.
NOTE:
Gain Limiting is the only automatic mixing function that can be active when the channel
is in
man
mode.
To activate Gain Limiting:
1.
Activate the
NOM
buttons on each channel you wish to include.
2.
Set the master
NOM gain limit
field in the range 1–10 (see page 27 to learn
how to set controls).
3.
Toggle the meter title to
NOM gain limiting
to view the amount of gain re-
duction.
