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 Sapphire or Handheld. 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 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 shift to a maintenance
charge when batteries are fully charged.
The 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 filter, the
Sapphire can function as a pass around hand mic.
The 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. The 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.
