Hooking up 5.1 speakers from ProControl

[babyseal]

Hi Everyone!

This might be a silly question, but here it goes... I'm trying to set up 5.1 surround speakers from ProControl's audio outputs. Now, I've managed to find out that Control Room out L/R is the front L/R, and Control Room Alt out L/R is the Center/Sub, but I can't find the output for the surround L/R! (Out 5-6 from Pro Control) I tried connecting them to ALt Out L/R, but the main vol knob doesn't control the level on them. I'm using smart pan pro w/ PT's analog outs 1/2 - Main L/R, 3/4 - Center/Sub, and 5/6 - Surr L/R. I've hooked up ProControl Analog ins as, Main In L/R - PT out 1/2, Sub 1 L/R - PT out 3/4, and Sub 2 L/R - PT out 5/6. Incidentally ProControl's manual doesn't say how the Analog outs from it should be connected to 5.1 speakers...

Thanks!
