Hey Dan or anyone else out there in the know. I just bought the GK 2001RBP preamp from Riks Music. I plugged in everything correctly but I can not get the Tweeter output to work. It doesn't work either in Bi-amp mode engagued or not. I have a stereo male 1/4 inch plugged into the Chain Out on the preamp. It was my understanding that this is a Stereo output according to the manual. THere is no other way in my opinion to get any other output from this preamp other than using the direct out. I have the stereo plug plugged into my amp. I know that the cord from the preamp to the amp works because I plugged into my home stereo and both channels work. Do I have a defective preamp? Or am I doing something wrong?
