Figure 4-4 Connecting the Microphone Pods to the XT Codec Unit of SCOPIA
XT4000 Series
Connecting an External Microphone System
When the two-pod configuration is not sufficient for covering the room, use an external
microphone system.
You need to acquire audio mixers from third-parties (for example, Clear One). An audio mixer
can connect multiple microphones, mix them, cancel the echo and generate a single audio
stream that feeds into the audio inputs of your SCOPIA XT Series XT Codec Unit.
Make sure the microphone mixer provides these connectors: an analog audio I/O (mini jack
3.5”) connector and a digital optical connector with a mini-TOSlink adapter
SCOPIA XT Series supports echo cancellation on the external audio interface.
You must enable the echo canceller when working with an external microphone system that
does not contain echo cancellation. See “Configuring the Echo Canceller” on page 52.
Disable echo cancellation when working with an external mixer that handles echo cancellation
externally.
