INTEGRATING THE UNIT INTO YOUR SYSTEM
VORTEX EF2211/EF2210 Reference Manual 20 Technical Support: 800.932.2774
this value to 18 would result in the microphone signals being attenuated by 18 dB
when gated off. This value is set independently for the automixers.
Automixer Reference. When enabled, the echo canceller reference becomes
a muted input in the automix so that far end audio coming from the speakers does
not gate on local microphones.
Reference Bias. Adjusts how much gain is applied to the Automixer Refer-
ence signal. The higher the gain, the harder it will for local talkers to gate on a
microphone.
Channel Settings.
Automixer. This allows you to select between no automixer and Mixer 1 for
Input 1.
Threshold Type. Sets adaptive or manual automatic gating thresholds per
input. The default is adaptive.
Gating Mode. Sets the automixer gating control mode for the input channel 1.
The possible modes are Normal Gating, Microphone Forced On, or Microphone
Forced Off.
Adpative Threshold. This allows you to determine when to gate a micro-
phone 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 input channel 1.
This value is only used if the input set to Manual Gating via the T
HRESHOLD
T
YPE option.
Gate Priority. The priority of each microphone can be assigned a value rang-
ing from 1 to 4. Priority 1 microphones have priority over priority 4 micro-
phones 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.

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 (applies only to Vortex
devices with 2 automixers)
• One large automixer, sharing automixer functions with other devices linked to it
• Two large automixers, sharing automixer functions with other devices linked to it
(applies only to Vortex devices with 2 automixers)
