Mix to Far End

The following controls facilitate a mix of mic and program audio that is sent to the far end via
USB to the computer. See Figure 11, below.
• Mic Volume — The master volume control is shown in purple and the mix‑points it
controls are also shown in purple. The mono mic signal is routed to both the left and
right paths of the USB Out.
• Program Volume — The master volume control is shown in green and the mix‑points it

Typically, mic volume will be set louder than program. It is recommended that the Mic
Volume control be set to 0 dB, or unity gain, which is the optimal level sent to the USB
Out and received by the computer. Program Volume is then set relative to the mic volume,
providing a good listening level such that the far end does not need to make an adjustment
to their volume control to compensate for discrepancies between mic and program volume
levels.
NOTE: The ducker can be used so that when the microphone (a talker) and program
material are active simultaneously, speech takes precedence over program so that
speech can remain intelligible.
