IRB-30 body-pack transmitter
The Body-Pack Transmitter (IRB-30) is usually worn
on the waistband with an external microphone
plugged in, i.e., Lapel (LM-835), Collar (CM-835)
or Headband (HBM-935). Or with a lanyard and a
Plug-in microphone capsule (LM-300) plugged into
the top, it can be worn as a pendant microphone/
transmitter. Ten transmitting diodes provide 180°
spherical transmission, assuring optimum connec-
tivity. A volume control allows adjustment of the
microphone volume. The external battery contacts
accommodate the convenient use of a drop-in
charger.
It is imperative that the
transmission window not
be covered or obstructed
from transmitting to the
sensor. Do not place in
pocket.
