Sidechain Filter - Set High Pass and Low Pass filters
for the input open mic detection to cut off frequencies
below and above the normal speech range that may
cause false triggering of the mics.
Press the
Fn
key to open the Setup screen and access
the sidechain filter. The reset default settings are
250Hz and 5kHz.
Scenes and the AMM
AMM settings are stored in Qu Scenes. These can be
blocked from Scene recall using the Scene Filters.
Go to the
Scenes / Global Filter
screen to block or
allow AMM settings from all scene recall. Use the per
scene Filters to block the AMM from individual scenes.
User Permissions and the AMM
As the AMM is accessed in the
Setup / Audio
screen it
is always blocked from the Standard and Basic users.
It would be unusual to allow users other than Admin to
set up an automatic mic mixer. However these users
can still view but not change the AMM settings in the
Setup screen.
Priority Level – For each channel you can set a priority 'level' which will offset the amount of gain
going into the mix calculation and therefore give a higher or lower artificial gain to that channel.
This is a variable slider with a range from -15dB (low priority) through 0dB (no offset) in the middle
to +15dB (high priority) at the top. For example, priority can be used to give the chairman or main
speakers a greater share of the gain when several people are talking, or to allow override of
audience question mics. Start with all Priority controls set to 0dB (mid position).
AMM In/Out – You can switch the
AMM in or out to hear its effect on
the mix. Start with it switched In
and all channels turned OFF.
Gain activity meter block – These level meters give you a real time
overview of the AMM gain distribution for all 16 channels. They light
for channels switched ON. Touch the left or right of the block to
bring CH1-8 or CH9-16 into the main view below.
ON/OFF – Touch to turn on the channels
you want to be affected by the AMM. The
AMM sets the channel fader to ‘0’, takes over
gain control and lights the gain meter.
We recommend you first turn down the
mix master fader to avoid unexpected loud
sound in the PA if the gain structure has not
yet been set for the room.
Gain Meter – Dynamically
shows the gain applied by the
AMM to each channel. You can
see how the gain is shared
when different combinations of
mics are active.
Gain range shown is -25dB to
+5dB.
The top of the light grey
section shows the 0dB
point where the AMM has
no effect on the gain. All
meters would read 0 when
the AMM is switched out.
One meter would read 0 it
was the only channel
turned on in the AMM.
