Enable AGC on input channel B | Polycom RS-232 instruction

This command was introduced in firmware version 2.5.0.

This command is a channel boolean command. See Section 6.3 and Section 6.1 for more information on this type of command.

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
S01LAGCB1	Enable AGC on input channel B.
S01LAGCA0	Disable AGC on input channel A.

8.69.LAGCLINKAB -- Enable or Disable Stereo AGC Linking on Inputs A and B

This command links the line input AGC of inputs A and B into a stereo pair. The overall volume level of the stereo signal will be analyzed, and the same gain will be applied to both channels.

This command has some side effects on the way the other line input AGC commands work. When LAGCLINKAB is first enabled, the settings for LAGC, LAGCMAX, LAGCMIN, and LAGCRATE on channel

A will be copied to channel B. The original settings for channel B will not be restored after LAGCLINKAB is disabled. Acknowledgements will be sent for any changes to channel B. From then on, any changes for these commands for either channel A or B will be set for both channels, and acknowledgements will be sent for both channels.

This command is a boolean command. See Section 6.1 for more information on this type of command.

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
