This command sets the effective output gain of the corresponding AEC reference. When doing volume control of room speakers, it is a good idea to adjust this reference gain along with the speaker output gain so that the AEC is aware of any volume changes. This will help prevent short echoes when volume changes are made.

There are two AEC references on the EF2280, EF2241, and EF2241, so there are two separate commands, REFGAINR1 and REFGAINR2, for controlling the effective output gain of R1 and R2, respectively.

There is only one AEC reference on the EF2211 and EF2210, so there is only one command, REFGAINR1 for controlling the effective output gain of R1.

This command was introduced in firmware version 2.5.0.

This command is an integer command. See Section 6.2 for more information on this type of command. The minimum and maximum values for this command are -100 and 20, 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

S01REFGAINR16

S01GAINP>3

S01GAINP?

Description

Set effective output gain of AEC reference 1 (R1) to 6 dB.

Increase phone output gain by 3 dB.

Query phone output gain.

Status Message

S01REFGAINR16

S01GAINPx , where x is the new value of the phone output gain. If this command was issued after the example above, then the status message would be S01GAINP9 .

S01GAINPx , where x is the new value of the phone output gain. If this command was issued after the example above, then the status message would be S01GAINP9 .
