Mixing Modes:

The EasyUSB Mixer/Amp supports three distinct audio mixing modes for common audio conferencing

applications in which the product may be used. The mixing modes are selectable from the rear dip switches on

the EasyUSB Mixer/Amp. Each mixing mode automatically reconfigures the internal matrix mixer for audio signal

routes required for proper operation of the acoustical echo cancellation functions within the EasyMic devices. All

mixing modes will support PC-based audio conferencing.



USB Conferencing Mixing Mode (Default): The USB Conferencing mixing mode is the default configuration and

is intended for use with a PC running a Unified Communication soft-client application. In this mode, the

EasyUSB represents a USB playback & recording device to the PC.

Video Conferencing Bridge Mode (Switch 2): The VC bridge mode is intended for interfacing the EasyUSB

Mixer/Amp to a traditional videoconferencing endpoint that may have been previously installed within the room.

In this mode, the internal matrix mixer creates the appropriate routes required to bridge the USB audio and

traditional VC endpoint audio signals for proper conferencing operations. This allows both the far end (PC & VC)

to hear the local microphone audio. In addition, the local participants will hear the audio originating from the PC

and VC far end.

Recording Mixing Mode (Switch 3): The recording mixing mode creates an audio mix of the USB RX (from the

far end) and the local EasyMic audio signals. This record mix is sent out the Line Output of the EasyUSB

Mixer/Amp. This mode can be used for sending local & far end audio during a conference to an external

recording device (DVD recorder) or external streaming device (Vaddio A/V Bridge).
