As shown in the Figure 2, the Master relays the voice signal from a Slave
to other Slaves. Therefore, the coverage distance of wireless
communication can be expanded in the case where the Slaves are
centered around the Master.

5. S9 Mode
S9 operates as Main Master, Sub Master, and Slave depending
on the ID setting of the device.
Main Master sends beacon signals for group communication as shown
in the Figure 2, and the Slaves operate in synchronization with beacon
signals.
Voice channels in a group are assigned to the devices with ID 0~8.
Wirelessly transmitted voices from each device are received
simultaneously at the terminal end from maximum of 9 channels.
These simultaneous voices are mixed within the device at the terminal
end and heard as the nal voice.
