infrared microphone/transmitters
e infrared microphone/transmitter is comprised of a microphone input, signal processing
circuits and several emitting diodes that transmit the vocal signal to the sensor.
e microphone/transmitter can be the Sapphire or Handheld.  e 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.
e drop-in battery chargers are speci cally designed to recharge lithium & NiMH batteries
at an optimum rate for maximum operating capacity and extended service life. Charger will
automatically start charging the batteries upon insertion and will shi to a maintenance charge
when batteries are fully charged.
e Sapphire’s vocal clarity is unsurpassed. Its high
level output is achieved by the unidirectional (Cardioid)
microphone and a unique free air suspension system.
With a built-in breath  lter, the Sapphire can function as
a pass around hand mic.
e strategic alignment of the emitting diodes assures
reliable connectivity throughout the room without static
or drop out.
With a tap on the power button, the microphone is muted
for private conversation—tap again to restore to normal
operation.  e auxiliary input allows wireless playback
of your iPod™ through the Sapphire. A three position
slide switch provides selection of low, medium, or high
microphone sensitivity.
