DIM jumper configuration
Removing either or both of the Dim jumpers mutes the program audio dur-
ing a talkback session, while inserting either or both will dim the program audio
approximately 20db below normal program levels. Use the table below along with
the jumper layout sheet in the appendix to properly configure. Factory defaults have
these jumpers installed.
Right ear talkback enable jumper:
In a talkback session, talkback audio is always feed into the left ear. Placing
a jumper over the desired header will enable talkback audio in the right ear. Use the

Remote Control input jumper set-up
Each optically isolated input is equipped with a four-position header.
The header is labeled JPxx. The factory default is set for a DRY (5 vdc source) input
(switch, contact, open collector) with a jumper between 1 & 2 and another jumper
over 3 & 4. To change the input to WET (user supplied voltage between 5 and
24vdc), remove both jumpers and place ONE jumper over pins 2 & 3. Use the table
below along with the jumper layout sheet in the appendix to properly configure.
! NOTE: Refer to the schematic diagram for the proper polarity when attaching
equipment to each input.
