Reference Manual
(NOM) limit for each linked automixer.  The maximum value for this command 
is 64.  This NOM limit is a “global” limit, meaning that this limit applies to all 
linked automixers with the same Bus ID.
Off Attenuation. Sets the Off Attenuation (in dB) for the specified automixer.  
Setting this value to 18 would result in the microphone signals being attenuated 
by 18 dB when gated off.  This value is set independently for each of the auto-
mixers.
Channel Settings. 
Automixer (Inputs 1-4). This allows you to select which automatic microphone 
mixer (1 or 2) a particular microphone channel is assigned to.  A microphone 
may only be assigned to automatic mixer 1, automatic mixer 2, or neither (but not 
both).
Threshold Type. Sets adaptive or manual automatic gating thresholds per input.  
The default is adaptive.
Gating Mode. Sets the automixer gating control mode for specified input chan-
nel.  The possible modes are Normal Gating, Microphone Forced On, or Micro-
phone Forced Off.
Adpative Threshold. This is also referred to as the Adaptive Threshold.  This 
allows you to determine when to gate a microphone on based on an estimate of 
the background noise level.  The default value is to gate a channel on if it is more 
than 10 dB louder than the background noise level.  Values range from 0 to 100 
dB.  To set the Adaptive Threshold, scroll through the Adaptive Threshold range 
and select the desired Adaptive Threshold by pressing E
NTER
.
Manual Threshold. Sets the automixer gating threshold for the specified input 
channel.  This value is only used if the input set to Manual Gating via the

 option.
Gate Priority. The priority of each microphone can be assigned a value ranging 
from 1 to 4.  Priority 1 microphones have priority over priority 4 microphones for 
gating.  The default is to have all microphones set to priority 1.  If Chairman 
Mode is enabled, all microphones including ones with priority of 1 will be gated 
off when the Chairman mic gates on.

EVICES
When using more than one Vortex device in your room system, you have several pos-
sibilities for how you configure the automixer.  Each device can operate as one of the 
following:
One automixer, independent of other devices linked to it
Two automixers, independent of other devices linked to it
One large automixer, sharing automixer functions with other devices linked to it
Two large automixers, sharing automixer functions with other devices linked to it
