Direct Program Listen Enable / Disable Jumpers
By default, each US-2002 program input can be heard by all intercom stations that are listening on the corresponding intercom
channel. This includes the US-2002. Program input routing to the intercom channels can be turned on or off via the US-2002
front panel programming. See “External Program Input and PA Output” on page 13. Additionally, all program signals can be
routed directly to the US-2002 speaker or headset. This lets the US-2002 operator hear the program inputs even if they are not
being routed to the intercom channels.
To disable direct program listening in the speaker or headset for one or more program inputs , do the following:
> Reset the appropriate jumper as shown in Table 2 .
