all of my experimenting with XLR matching transformers is not completely wasted. I did figure out this one really neat trick which has elimited the annoying hum and computer noise in my computer speakers.<\/p>\n
(I should mention that my computer speakers are a pair of Mackie SRM450s with balanced inputs, and that most of this does not apply to you normal consumer-type people)<\/p>\n
Take two XLR -> 1\/4″ matching transformers (currently $15 at a guitar center near you), plug them into each other using a 1\/4″ F-F adapter ($4), and add a XLR male-male to one of them ($8). Now what you have is a single-channel isolation transformer! Perfect for when you have to run the PA off four different wall sockets in order to get enough power to avoid opening breakers when you start feelin’ the bass. Add heatshrink to the transformer -> F-F -> transformer part, and you have a very useful generic adapter to keep in your adapter kit. Probably a good idea to keep two or three of them around.<\/p>\n
Also, when running Mackies off unbalanced outputs that may have less than perfect grounds, a single isolation transformer plugged into a RCA-m->1\/4″-f adapter (assuming you’re dealing with a RCA out) will improve the situation mightily. Very useful for ‘booth’ speakers when the power supply is noisy (and, at raves-^H^H^H^H^Hparties, they always are).<\/p>\n","protected":false},"excerpt":{"rendered":"
