Figure 8: MAIN-SUB OUTPUTS
Figure 9: LOOP OUTPUT-INPUT
The flexible output configuration of the LX-1 can be a real problem solver. A typical example
would be feeding MAIN audio to a transmitter and using SUB audio for studio distribution. The
separate outputs could also feed a second transmitter.
In AM/FM stations the LX-1 could continuously feed an FM transmitter via the LOOP output
while an AM feed could be sent from the MAIN outputs. The LOOP function, under remote
control, could then switch between simulcasting FM on AM, or select from a separate AM source
via the LOOP input.
Another use for the LOOP function is for selecting an alternate program source when it is desired
to return to the previously selected source. This is an ideal way to generate an EBS test. Another
possibility is relaying EBS tests under control of the originating station.
The LX-1 is ideal for use at unattended transmitter sites. By remote control the LX-1 could select
a satellite down link or automation feed and switch back to the studio feed.
There are times when a monophonic feed is needed for an AM transmitter. There is a simple way
to achieve this with the LX-1 An L+R feed can be derived by making a simple resistive combiner
using four 300O resistors. See figure 10.
