Usage 3.
Microphone DM30 is purpose made to be used with other units
of the same type. Together with the other units it forms a system
for two-way communication among teacher and students.
A typical set-up consists of one unit
configured as a teacher unit, and one or
several units configured as student units.
This set-up allows each student to hear the
teacher and fellow students that are using
the push-to-talk feature.
Figure 1: The teacher's voice is mixed with
the voice of the student pushing the function
button and sent back out to the rest of the
class.
