Hey Reabsco,
Nice find. I did notice this device has AV in. I do know that there is a 1/8" plug you can get at Radio Shack which will allow coaxial input, hence I am pretty sure this means you can receive cable, but I wonder if it would need a cable box to change the channels. I doubt if the receiver itself would be capable of choosing cable channels or maybe it will be limited in the channels you can get (ie 2-13).
This is the online catalog page for it...
