TRIO MIC I/O Interface
The TRIO Mic I/O is an audio breakout interface for the TRIO Microphones. The interface provides power and
audio over Cat-5 to the TRIO MIC and terminates into a balanced line level audio source for connection to a
room’s audio mixer.

2) Mic Port: Four Mic Ports on RJ-45 connectors providing power and audio over single Cat-5 cable to the
connected TRIO devices.
3) AEC Reference Input: Acoustic Echo Cancellation (AEC) Reference input channel. A balanced line level
input. AEC reference signal should be a duplicate audio signal from the connected mixer that represents the
audio being sent to the loudspeakers within the room. A proper AEC reference is required for the TRIO
Microphones to work properly in a conferencing application.
4) Line Outputs: Balanced line level output of the TRIO Microphones for connection to the room’s audio mixer.
This signal will be echo canceled. An automatic microphone mixing function should be employed on the
room’s audio mixer if multiple TRIO microphones are used in the installation.
