    Has anyone bi-amped their system with some pro audio gear such as the Rane AC22. It seems to me an easy thing but I get a horrible buzzing sound when I power it up. Input and outputs are 1/4" and I simply cut up some patch cords and fitted the male 1/4" to the ends. Any help would awesome. No

    Hi,

    I use 2 DBX 234 active crossovers and had a similar issue at first. I found that running a ground wire from one of the screws on the chassis to my system ground solved the buzzing. My system ground consists of 3 stacked 10' ground rods outside the house with a #2 solid tinned copper wire run to a bus bar inside. I also found that an ungrounded cable tv splitter caused some unwanted noise as well.
