Values range from 0 to 100 dB. To set the gate ratio, scroll through the gate ratio
range and select the desired gate ratio by pressing E
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

Microphone Priority. The priority of each microphone can be assigned a value
ranging 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 EF2280 in your room system, you have several possibili-
ties for how you configure the automixer. Each EF2280 can operate as one of the fol-
lowing:
• One automixer, independent of other EF2280s linked to it
• Two automixers, independent of other EF2280s linked to it
• One large automixer, sharing automixer functions with other EF2280s linked to it
• Two large automixers, sharing automixer functions with other EF2280s linked to
it
To operate the EF2280 in any of the above possibilites, two global parameters need to
be changed: the A
UTOMIXER
parameter chooses which automixer the input channel will be on (this is changed
either on the A
UTOMIXER
page).
The B M parameter is used to assign one of the two internal automixers to one
US IXER
of the EF Bus automixer groups. For example, consider three EF2280s each of which
has four microphones assigned to Automixer 1 and 4 microphones assigned to Auto-
mixer 2. Now, if each of these EF2280s sets their Automixer 1 to have Bus ID 5, then
the three automixers (one from each EF2280) will work as a single automixer con-
taining 12 (3 x 4) microphones. Setting B
