using the rca jacks
The Duplex features RCa InPUT and THRU jacks for
each channel allowing you to patch in to a personal
monitor system. You can also use the Mono sUM
switch to connect one or two stereo devices in either
mono or stereo depending on how you choose to patch
it. as described earlier, the balanced XLR outputs
connect to the Pa or recording system (not shown in
the diagrams).
basic stereo connection
When connecting a stereo device like a DJ mixer to the
Duplex, the Mono sUM and XLR sEL switches should
be set to their outward positions. Use good quality
cables to connect to the channel-1 and channel-2 RCa
In jacks. The RCa THRU jack can be used to pass the
stereo signal on to another audio system.

Dual stereo devices
You can retain full stereo operation with two devices
by connecting the left and right outputs as shown and
pushing the Mono sUM switch inward on both channels.
Connected this way, the left signals from both devices are
summed to one Duplex channel and the right signals are
summed to the other. You can adjust the relative levels
using the device's volume controls. You can even connect
a personal monitor to the ¼" THRU jacks.
