Reply to Do I need to buy an Audio Interface?

Right, my set up ATM is:

MacBook Pro 15" running Logic Pro 9
Mac Power PC G5 running Logic Pro8
KRK RP8 G5 monitors
Behringer UMX Midi Keyboard
CODEX USB Microphone
Maschine

And I have Traktor SP2 with Audio 10.

Now, do I need an audio interface with my set up?

Sometimes I want to just play music from my MacBook iTunes out from my monitors and I have currently been doing this via an RCA cable split with one end going into my RCA monitor input, and the other end into a mini-jack adapter into my MacBook, and I'm sure this is dodgey.


Is there another way to hook my monitors up with my MBP & Logic? Been trying to get this sorted for a while now,

Thanks.

I use 3Pin XLR to connect my monitors to my DJM 500 mixer, so maybe a Audio Interface with XLR ins/outs?
