wiring is shown in Figure 2.
NOTE: In the factory default configuration, the
IFB-325 belt packs receive IFB audio on
pin 3 of its XLR connector. In this
configuration, the belt pack’s internal
shorting plug J3 is set to pins 2 and 3
shorted. This is NOT the correct
configuration for use with the IFB-828. To
change the setting open the belt pack and
reset the H3 shorting plug so that pins 4
and 5 are shorted. Refer to your IFB-325
manual for further information.

4030 accept either monaural or stereo
earsets. However, for the standard
application of the IFB-828, only a
monaural earset is required.
