This command is saved to non-volatile memory only as part of a preset. The state of this command will be restored after power-up only if a preset is saved and that preset is set to be the power-on preset.

Example Description

Set off attenuation for automixer S01AMOFFAT118 1 to 18 dB.

Query current off attenuation for S01AMOFFAT1? automixer 1.

Status Message

S01AMOFFAT118

S01AMOFFAT1x , where x is between 1 and 100 depending on the current setting of the off attenuation for automixer 1.

8.27. AMPRIOR -- Set Gating Priority for the Specified Mic

This command sets the automixer gating priority for the specified input channel. Priority levels of 1-4 are allowed with 1 being the highest priority and 4 being the lowest.

This command is a channel integer command. See Section 6.3 and Section 6.2 for more information

on this type of command. The minimum and maximum values for this command are 1 and 4, respectively.

This command is saved to non-volatile memory only as part of a preset. The state of this command will be restored after power-up only if a preset is saved and that preset is set to be the power-on preset.

Example Description

Set microphone input 1 to gating S01AMPRIOR11 priority 1.

Query current gating priority for

S01AMPRIOR1? microphone input . 1.

Status Message

S01AMPRIOR11

S01AMPRIOR1x , where x is between 1 and 4 depending on the current gating priority setting for microphone input . 1.

8.28.AMREFB -- Set Automixer Reference Bias for the Specified Automixer

This command sets or queries the reference bias for the automixer reference mode feature of the specified automixer. When enabled, the automixer reference feature uses the AEC reference to prevent local microphones from gating on audio from the remote side. The AMREFE command controls

the enabled status of this feature. The AMREFB command can be used to bias the AEC reference signal to make the automixer even less likely to gate on remote audio.

The first argument in this command specifies the automixer number (always 1 on the EF2211) and the second argument specifies the reference bias in dB.
