Well, yes and no. The BX5's can be run off instrument, mic, or patch cords just fine. However, the 1/4" ins are balanced. Of course, it also depnds on what monitor outs you have to come from. Most are balanced 1/4", but, for instance,
my Roland VS1824CD has RCA monitor outs, so you have to go from RCA to XLR or TRS.
However, the original poster called those cables "wires", so I'm guessing he doesn't know jack, and all this technobabble is just going to give him headaches, so here's the non-Reader's Digest version.-
The monitors have 3 pin jacks, called XLR, like mic cables. They also have 1/4" jacks, like a guitar cable. There are 2 types- TS (tip-sleeve) and TRS (tip-ring-sleeve), which looks like a stereo plug. Cable connections with 3 connectors, such as XLR and TRS are generally balanced, which uses the third conductor as a common ground. This reduces noise in longer runs of cable, and has a few other advantages. The 1/4" jacks on your speakers want TRS, and are so labeled. The guys above are debating the gauge and type of shielding that the cables shoud have. For cables that short, and the fairly weak signal the cables are carrying, almost any gauge will work. However, I would not recommend an unshielded cable. Powered monitors are prone to picking up radio frequency interference (RFI), and with unshielded cables, you are likely to hear AM radio coming out of your monitors.
First, figure out what kind of plug you need for whatever your monitor outs are. Then get two good studio patch cables that go from those (whatever they are) to either a 1/4" TRS, or a male XLR.-Richie
