Enhanced Room Coverage
Optional microphone extension kits provide enhanced room coverage that can be further expanded by linking
two units together in Linked Mode. This feature allows you to use the conference station in a larger room, or
to enhance the audio and voice experience for larger groups of in-person attendees.
When two conference station base units are linked together to expand the audio coverage area, one conference
station acts as the primary device and the other sound base is the dependant or secondary device. In Linked
Mode, the primary base station supports one or two wireless microphones, or it supports one wired microphone.
The secondary unit supports only one wired microphone; a wireless microphone cannot be connected to a
secondary Sound Base. Youcannot mix microphone types on the devices. Consult the following tables for
allowable configurations.
