IRT-89 pendant transmitter
PM-505 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 adjustable
lanyard to position for optimum performance and
comfort. The transmitter is easily unclipped from
the lanyard for handheld use and student partici-
pation. Ten transmitting diodes assure continuous
connectivity. A volume control allows adjustment
of the microphone volume. An external mic input
(top/center) permits insertion of a unidirectional
microphone for enhanced performance and anti-
feedback. The external battery contacts accommo-
date 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.
