No, the RMX series and other QSC amps have no RCA phono-type input connectors.
You can probably find cables with a phono plug on one end and a 1/4" plug on the other. If you are in the US, Radio Shack should carry something like that.
Yes Radio Shack have a few models. I am using the gold-plated RCA-to-1/4" which did cost me $4.
BTW, I have the RMX 2450 which is great to drive my MMGs.

Bob: Are you saying that the inputs are not balanced? A phono to 1/4" cable is simply an adapter. And should we really be buying them from Radio's China Shack? I've been told that interconnects should cost at least a bazillion dollars for six feet. ;)
The inputs are balanced. If you plug a 1/4" tip-sleeve connector into the input jack, it shorts one leg of the input to ground, and so it becomes unbalanced. That works well for short interconnect cable runs.
One can always insist on paying more for cables if that pleases his or her ear-go. ;^)
My rmx1450 has 1/4 stereo jacks at input, balanced.
I run them with a 1/4 mono jack, so I run unbalanced. The jack just shorts the ring. I've had no issues in the last 6 years running them this way.
I would recomment gold plating on both ends to eliminate intermittants, but have run nickel plated.
