I'm looking into a small PA and before I buy what I want to buy, I want to make sure I can get the most for my money. The set up I'm looking into is a soundcraft 124fx mixer and 2 Kustom PW50s.
In order to connect the mixer to the speakers I was thinking I could make my own cables. The main mix out on the board is a 1/4" TRS (which i'm pretty sure is just stereo?), and the input on the speaker is for a male xlr. My debate is weather to use standard mic cable in the wiring, or if quad mic cable would work. The quad cable is supposed to help with noise rejection, but will it work for this instance?
Another question that I cannot find the answer to comes from wanting to run a keyboard or guitars through the board. Since I plan on using all 4 mic/line ins for mics, I am forced to move for the stereo inputs for the rest. If I want to plug in a keyboard, acoustic guitar, or headphone out of a small guitar amp into the board should I use a DI box? If I use a balanced cable without a DI box will a ground loop still occur, since it has a ground wire? Also, should I use just one mono 1/4" into the left stereo port, or convert to 2 separate 3 pole (TRS?) plugs and plug into both stereo channels for guitar and keyboard?
