About Gain Optimization
This topic describes some general principles for optimizing gain values using the CONVERGE Pro 2 and
CONVERGE Huddle.
Note:
Specific information about optimizing gain for particular channel types can be found in the topics for
changing channel properties.
Keep the following principles in mind as you adjust gain across the system to achieve the desired result:
• Simplicity. Avoid complex gain structures. For example, avoid boosting the gain of an input audio at
one point along its audio path, then dropping it as another point, and boosting it again at a later point.
Also avoid unnecessarily complex audio routing, such as routing an audio signal through multiple
processing or fader blocks.
• Unity Gain. It is always best to set inputs to a similar gain level and maintain that same gain level
through the system, with a few exceptions:
• When mics are routed to local speakers for sound reinforcement this audio will typically need to be
reduced at crosspoints or on a processing block to prevent local feedback. Care should be taken to
keep this routing separate from the routing of mics to the far end of a teleconference.
• When audio is routed from a line output to a video conferencing system input, the line output gain
will need to be adjusted according to the requirements of the input on the video conferencing
system.
• Optimization Order. ClearOne recommends optimizing gain of your entire audio system in the
following order:
1. Microphones
2. Line Inputs
3. Audio/Video Conferencing Inputs
4. Amplifiers
5. Speech Lift
• User Gain Control. User control of room audio levels should be done within the CONVERGE Pro 2 or
Huddle. If the volume is controlled at an external amplifier or other external device, volumes changes
are likely to cause far end echo, at least until the system converges.
About Dialer
A Dialer application is available to CONVERGE Pro 2 users who have a telco-capable (a model that has a
“T” at the end of the name) or VoIP-capable (a model that has a “V” at the end of the name) device.
Using the Dialer application, you can:
• Place and receive calls via a SIP server
• Store contact information
• Designate contact favorites
• Forward calls
• Make conference calls
