Hey Richie,
you don't say make/model of the active speakers and if they have XLR balanced or 1/4" input, HI z or LO z impedance. But typically the outputs from the console should be line level, balanced (pin2+) 0dB if you are unbalanced 1/4" you would need an adapter with tip to pin2 and ring strapped to pin 1 and 3 on the xlr.
If your active speakers are -10dB input you will need a resistive pad/attenuator on the output of the console (google inline pads)

I used to have several 24/4/2 studiomaster(RSD) consoles a long time ago back in the UK.

hope this helps

The 15" JBL Eon would be ideal for this, you can usually pick them up from ebay for a reasonable price. One thing to watch is that as this is an old (probably over 25 years!!) budget desk the XLR outputs aren't balanced and the hot (signal) connection is on pin 3 if you're connecting it to a active speaker with balanced inputs using the pin 2 hot convention, to achieve optimum results I'd recommend that you make up a cable like this:

Speaker pin 1 connect to screen of cable leave unterminated and insulated at mixer end
Speaker pin 2 connected to pin 3 of mixer output
Speaker pin 3 connected to pin 1 of mixer output

This method used to be called pseudo balanced (maybe still is??) and will reduce hum and correct the phase of the system, just make sure that the screen isn't allowed to come into contact with any of the pins or shell at the mixer end, this is easily accomplished by cutting the screen where you have stripped the cable and pulling the insulation back over the stripped end, there will usually be enough give in the pvc to cover any exposed screen, use some helleman insulation sleeves or tape for a professional job.

Hey Richie,
Well I actually work for a sister company to Mackie, the SRM450 is a great value, also the JBL EON series is verey good, these are all pole mounted, so you should look at maybe getting ultimate support stands, or something similar

Hey Richie,
this is all pretty basic stuff assuming you are using a pro amp
try : PA System Schematic Diagram - for a simple layout

and this: Sound System Interconnection for a "decoder-ring" on interconnects

cheers
