The
Sound Choice Model SC-186K is a compact wireless infrared
audio transmitting system. The unit is completely
self-contained and includes a super-sensitive Crown PZM®
microphone. Its high gain internal pre-amplifier makes even
the faintest sounds audible. The Sound Choice Model SC-186K
system incorporates a powerful infrared emitter which
broadcasts audio over invisible infrared light waves. The
infrared transmission is received by high-gain headsets worn
by those needing hearing assistance. Styled in a dignified
oak case, the transmitter blends with both traditional and
modern government, courtroom or commercial settings.
The
Sound Choice Model SC-186K system has built-in equalization
circuits which de-emphasize the undesirable rumble of air
conditioners, traffic and fans while emphasizing frequencies
that contribute to the crispness and intelligibility of
speech. Its built-in compressor/peak limiter automatically
adjusts the volume so that speakers in close proximity to
the unit will not cause distortion in the receivers. Distant
speakers are automatically boosted in volume, while
unexpected peaks are instantly attenuated.
The
SC-186K has the ability to integrate into an existing sound
system or utilize the unit's own highly sensitive
self-contained microphone. There is also an output jack
included for transcription recording.
