Kaintuck Posted January 21, 2021 Share Posted January 21, 2021 So I'm just learning about my setup and thought some of you folks may be able to help. I have the Helix rack, hooked up using 4 cable to a Mesa Rectifier recording preamp, and this outputs to a mesa stereo 2:100 power amp. Basically I'm trying to use the recto preamp as my amp, I have it hooked up per 4 cable method, the effects loop in place of the amp, and everything works, with the exception of I get a fair amount of hum to the speakers. I have the input gate on, but this doesn't really do anything for the hum. I've tried running my rocktron hush in between the send on the mesa and the return to the helix, and this just kills my volume even if the rocktrons gate isn't on. I took a mesa preset I had and just substituted the fx loop for the amp so I could compare the Helix rectifier model with the real thing, but the extra noise on the "real" preset is aggravating. What should I be doing different?? Thanks a lot for any advice! Quote Link to comment Share on other sites More sharing options...
