Your receiver is designed to receive two
microphone signals at once. For example,
two teachers (or a teacher and an aide)
may each use a microphone. Or, one
teacher can use a microphone and stu-
dents can use a pass-around microphone.
Microphones must be on different channels
or interference will occur.
