Jones Posted November 18, 2020 Share Posted November 18, 2020 Hi there, I'm connecting this subwoofer to an old pioneer amp with a pair of PSB alphas. The amp is 120 Watt and 60 Hz. It has a pre amp subwoofer jack on the back for an RCA cable and I plugged the other end into the white/left/LTE port on the subwoofer. I assume that is the correct way to do it? Also, how high should I now set the gain and the low pass control? For now I'm leaving gain at noon position which I believe is 0 Db, and low pass is at about 1:00. as I the manual says it should be higher for smaller speakers. Does that sound about right, or should I change things? Thanks in advance. Quote Link to comment Share on other sites More sharing options...
wuzzzer Posted November 19, 2020 Share Posted November 19, 2020 Around 80Hz for the crossover, 10 to 12 o'clock for gain depending on how much bass you want. If you plug the cable in the LFE input on the sub it may bypass the sub's crossover so I'd try the red one instead. Quote Link to comment Share on other sites More sharing options...
Jones Posted November 19, 2020 Author Share Posted November 19, 2020 Ok, thanks. I thought you were supposed to use the white if only connecting one cable. At least that is what I thought it said in the very limited manual that came with the sub. the other option I was considering was an RCA split that went to both red and white on the sub.
