owner's manual
(IRT-60) sapphire transmitter
Th 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 fi lter, the Sapphire can function as
a pass around hand mic.
Th 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. Th 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.
