IRT-89 pendant transmitter
LM-300 plug-in microphone capsule
The Pendant Transmitter (IRT-89) is a complete
self-contained unit with a built-in microphone. It
is worn around the neck, suspended by an adjust-
able lanyard to position for optimum performance
and comfort. The transmitter is easily unclipped
from the lanyard for handheld use and student
participation. Ten transmitting diodes assure
continuous connectivity. A volume control allows
remote adjustment of the microphone volume. An
external mic input (top/center) permits insertion of
a unidirectional microphone for enhanced perfor-
mance and anti-feedback. The external battery
contacts accommodate the convenient use of a
drop-in charger.
Although the built-in microphone provides satis-
factory performance, the optional plug-in micro-
phone is a unidirectional microphone thus repro-
ducing better vocal quality and rendering more
gain (more volume before feedback). With the
windscreen, the pendant can be used as a hand-
held microphone without breath pops.
