Help Needed: Presonus Firebox to Behringer MS20 Monitor connection

Hi, I got my Firebox and Behringer monitors, but I still can't get any sound out of the speakers... I'm really not up on what cables connect to what, so if anyone can help, that'd be grand :)
I'm using a G4 Mac, the firebox is connected to that via the firewire port.
The Left speaker connects to the right speaker via the cable supplied with it... so I know I got that right :P
on the diagram on the back of the box, is says to connect the firebox to the speakers via the 1.L and 2.R Main Out (fat phono jack style) ports. The firebox also has the Midi / S/PDIF port connections on the back, so I tried connecting one of those Red/White Aux 3.5mm cables from the S/PDIF connections to the Analog input 'Line 2' ports in the right MS20.
No luck.
Everything is plugged in and turned on, I've changed the sound settings on the mac and it can 'see' the Firebox, when I tap the mic/speak into it, I can see the speaker bar (or whatever it might be called) moving, so I know that's working?
The problem seems to be the Firebox to MS20 connection. Would buying 3.5mm to phono jacks solve the problem? Do I need to connect the Mac to the 'Coaxial' port on the back of the MS20 as recommended in the manual (then again, the manual assumes I'm connecting that to the interal soundcard). Do I have to turn the interal soundcard off somehow?
I thought I'd tray and get some advice before I go spending money on more cables.
Many thanks in advance!!
Here's some images that might be useful?:

Jul 11, 2007 10:37 pm That is one funky set up to connect a set of speakers. I don't understand why they don't simply have 1/4" jacks for each speaker. But anyway, it looks as though you can use a 1/4" pair to RCA connections to get the left and right monitor outputs of the firebox into the speaker then an RCA to RCA to get to the left speaker from there. That is the craziest thing that they would do that.
Jul 12, 2007 04:26 am I'm getting OSX v1.4 at the moment, hopefully that will improve my chances? Thing is, I have a cable that connects the R+L Line 2 ports in the back of the MS20 to one of the phono ports in the back of the Firebox... surely when I connect that up, in theory it should come out of both speakers, but in mono?
Instead I'm getting no sound :(
I'll see if I can pick up the leads you mentioned via ebay later.
Jul 12, 2007 03:45 pm get two seperate 1/4" unbalanced(fat headphone with ONE black stripe) to RCA (red and white style coaxial) adaptor cables....hosa makes them.
geez i can't believe behringer would make you hook them up like that....ick.

Jul 12, 2007 05:48 pm ^^^You're a legend! I was hoping I could get a link to what I needed, as I said before, I'm such a n00b when it comes to names of cables :P
Thanks!
Jul 19, 2007 01:08 pm Hi, just got the cable through today... plugeed it in... still no sound! I don't know where to go with this :(
Anyone else got any ideas?
Jul 19, 2007 01:58 pm actually scratch that... I have sound through the monitors! I can hear songs through itunes, so the hardware is working :)
...how for the mic...
that's still not working, i have 2 mics. When my Kam KDM550 is plugged in, I can see the bars go up and down responding to my voice, but I can't hear anything from it. When I use my Audio Technica AT2020 (which came free with the firebox, so ya wouldathought it'd work), I don't get the sound bars moving :(
Both mics connect via the XLR port, however, I don't believe my Kam mic requires phantom power, whereas the AT2020 does. I know the Firebox is capable of this phantom power thing, but how do I go about getting this to work now?
Jul 19, 2007 07:32 pm In order to use the 48v phantom power on the firebox you will need to have it plugged in with its power supply. I am not sure if they ship it with one or not. But there should be a switch on the front or back that says either phantom power or 48v.
Jul 20, 2007 04:04 am ^^^yea, I got the power supply with it, so that's no probs... there is no switch however on the firebox that allows you to flip between mains and firewire power. But later tonight I've mess about with a few more things with the firebox plugged into the mains and see if that works.
cheers!
Jul 20, 2007 08:43 pm I think it switches internally when you plug the PSU into the unit and hit the mains.
