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.
