I’m using Bluetooth/Spotify as my only way to listen to music on my HU Could be this be the reason why the dd1 is not detecting distortion?? I have a marine head unit, Fusion ra670 along with a JL 800/8v2 amp. I'm using the dd1 and it won't or can't detect any distortion from my unit. Heres what I've tried. New batteries used are Rayovac and then Duracell. I've tried hooking the red probe to positive speaker terminal (positive puts out signal) and black probe to ground. I've tried hooking the red probe to positive speaker terminal along with black probe to negative speaker terminal. I turned the INPUT SENSITIVITY all the way down, filter mode switched off. Even turned frequency levels up on the 3rd try even tho it wasn't necessary. Went through all the settings in my head unit, put everything to flat in each zone, and turned off loud options as well. I used the 0db 1khz and 0db 40hz test tones from the Smd website via bluetooth. The dd1 detects signal at around 15 and 40hz at 16, same for 1khz track. I kept going up on volume and the dd1 could not detect any distortion for both tracks 1 and 2 test tones. My head unit max volume is 24. I also made sure each zone volume limiter was set to 24 as well. I also have a JL Rd 1500 amp with 2 subs, I did not test that yet since I've been trying to figure out what's going on? What am I doing wrong? or could it be my Deck is distortion free, which I doubt.
