Hey guys im new and im seeking for a little help. I just purchased a randall rx120rh with rx412 cab and ups came and droped it off today. This amp is gorgeous there is just one problem cant get any sound of it. The amp lights up when i turn it on, i plugged a " a speaker cable" into the cab, but havent had any luck with the sound. I have tried both inputs and theres also a "ground" or "lift" switch, but cannot get anything no even a hum, or feedback. It has been very frustrating past couple of hours, lol, is there something that im doing wrong, or do i need a certain cable. I was reading about Ohm's and stuff but thats all chinese for me...Any help would be appreciated...
