Radial StageBug SB-6 - Isolator

Is the balanced output (xlr) a combination of the left and right signal or just the left? radial's website says its combined but this box says left?

If using with an iphone or ipad i'm assuming you use 1/4 trs cable for both right and left but wanted to make sure exactly which cable to use?

This is advertising the sb-5, but the picture is of the sb-6. what is the ad for?

What's the frequency respond range?
