The next Diagram depicts a similar configuration but interfaces to an external audio amplifier instead of using the
internal 2 x 20 watt amp within the EasyUSB Mixer/Amp. The EasyUSB Mixer/Amp will automatically configure
the Acoustical Echo Cancellation functions within the EasyMic MicPOD to work with these loudspeaker
scenarios.
For an optimum audio conference experience using an external amplifier, an end-user should
use the Volume Controls on the EasyMic for adjustments and avoid adjusting volume at the
external amplifier. Volume adjustments externally to the EasyUSB device will lead to
momentary occurrences of the dreaded half-duplex operation while in a call.
