AudioPipe AQ-3000 - any views or opinipns...?

I recently came across this power amplifier at my new job. It was already connected via its Speakon Outputs, snaked up a wall and through the ceiling, over to six HardBass HD10-XL Passive Monitors located in the auditorium. I have no user manual to explain, why the input channels seem to have both male and female XLR connectors, per input channel. Does anyone have any experience with poweramplifiers with this type of input connectivity, or more specifically any experience, (or a manual) for this power amplifier...?
