Numark PPD9000 Mixer
Simplest thing that could possibly work.
You can use the XLR Balanced outputs.
XLR Balanced with built-in-pad
If the Mixer has a button, switch or adjustment that allows you to attenuate (turn down) the output of the balanced XLR main outs, try the setting with the lower output.
Here is an example (Mackie 1402 VLZ)
Otherwise you may need to use a Pad for each output channel.
