Microphone Interface for the EasyUSB Audio Solutions
The PRO MIC I/O expands the Vaddio™ EasyUSB™
audio designs to include 3rd party microphones. The
PRO MIC I/O adds the capability of using traditional
A/V table microphones in a PC conferencing system
when used with the EasyUSB Mixer/Amp.
Front panel controls provide a simplified user interface
(four knobs and two LEDs) for setting the desired gain
on the connected microphones.
Dip switches on the rear panel allow the installer to enable processing functions including a low cut filter, a high
cut filter, phantom power (per microphone), a GPIO for mute status and finally a front panel lock-out to protect the
knobs from the “technical experts” that just can’t resist making a fine adjustment or three.
The PRO MIC I/O provides four (4) microphone inputs on 3-Pin female XLR connectors allowing table,
gooseneck or button microphones to be used in a custom design where microphone type, size, color, texture and
locations are critical to the end user or architect alike. Each input channel incorporates an echo cancellation
processing chain that is optimized for use with Unified Communications software applications such as Microsoft
Lync, Cisco Jabber, Skype, WebEx, Vidyo, GoToMeeting and many others.
