E THE MM-110 ELECTRET
CONDENSER MICROPHONE
An electret condenser microphone for use in
measuring the acoustic response characteristics of
the listening environment is provided with this unit.
Microphone input will be displayed on the spectrum
analyzer when the microphone is connected to the
front panel MIC jack, the MIC switch is turned on, and
a signal of level high enough to be measured | is output
through the speakers.
