Hi, I use a Zed-6FX with my electronic music setup. I use stereo Channels 3 an 4 for my stereo synth and stereo FX return, respectively, and have been trying to use Channel 1 for cassette playback and Channel 2 for my Oberheim Matrix 1000. Even after putting a Rolls Buzz Off between the outputs of these and the respective Channel 1 & 2 inputs, those channels hum incredibly audibly even after my attempt at gain staging per the manual and rolling the HPF all the way down on both. The Zed-6FX, as well as everything else I’m using, is plugged into the same Furman Power Conditioner. Is this a known issue? Can anything be done? Otherwise, I really love this mixer and have found the sound and build quality to be absolutely stellar. Thanks so much in advance!
