Gain Configuration
These Þelds are useful for attenuation applied to obtain adequate voice levels for the end users. It is recom-
mended not to alter this value unless solving an issue related to voice levels. (Default = 0)
● Transmit/Receive Gain
This is the base gain value that is applied to all calls (internal or external).
● Transmit/Receive Internal or External Bias
This option sets the Transmit/Receive levels for external and internal calls.
Setting this option to a positive (+) setting increases the volume level. Entering a
negative (-) number decreases the volume level.
Example: When the following settings are applied:
Transmit Gain = 2, Transmit Internal Bias = 2
Transmit Gain set for the channel of a call on an internal line would equal a total of 4.
● AGC ConÞguration
These Þelds are useful when controlling the gain of the system in order to maintain consistent audio lev-
els during a conference.
The default values are suggested baseline settings for the Aspire Conference Bridge
PCB. The values may need to be adjusted for optimal performance on your system.
