Question. I have 2 80's Crate Amps that I am using the clean channel for the HD500x to connect to. Question is how to I cable up in order to get a true Stereo sound? I notice there is the 1/4 inch left and right mono for the output on the HD500x but it isnt Stereo? Any advice would be appreciated.. Yes I use late 80s Crate Solid State amps, They are great for hair metal from the 80s era.
