infrared microphone/transmitters
The infrared microphone/transmitter is comprised of a microphone input, signal processing
circuits and several emitting diodes that transmit the vocal signal to the sensor.
The microphone/transmitter can be the Crescent or Pendant style worn around neck, or
Body-Pack clipped to your waist with your choice of microphone (Lapel, Collar, or Head-
band). The rechargeable batteries will provide 6–8 hours of service per charge. Place the
microphone/transmitter in the charger for overnight charge and it will be ready for another
day’s use.
The drop-in battery chargers are specifically designed to recharge NiMH batteries at an opti-
mum rate for maximum operating capacity and extended service life. Charger will automati-
cally start charging the batteries upon insertion and will shift to a maintenance charge when
batteries are fully charged.
The Crescent is a lightweight microphone/
transmitter designed to be worn under the chin
suspended by an adjustable lanyard. The Crescent
shape was designed for efficient performance
and user comfort. The dual internal microphones
render optimum voice pick up and quality vocal
reproduction. The Crescent provides an auxiliary
input (3.5mm) to accommodate the insertion of
an iPod
™
or similar device for supplementary
program material.
A soft touch mute button cuts the microphone
“off” for private conversation (the power LED
will flash in the mute position). A volume control
allows adjustment of the microphone volume.
The external battery contacts accommodate the
convenient use of a drop-in charger.
