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. -
Hello all, new to this forum and I’ve stumbled across here many times for research. Now brings my question and I’m hoping someone will be able to provide me with some insight with the DD-1+ (which I also recently purchased and have used a few times). While finding my maximum undistorted volume on the headunit, I notice the distortion light illuminates at about halfway on my 2016 VW Passat stock headunit but if i go a click up... the light stays out and continues to stay out until the headunit’s volume is maxed out. Now why is this happening, it’s been puzzling me all day, does my HU just distort at one point for some odd reason? Or is this device just capable of detecting such small amounts? So far I’m highly satisfied with it just have this very question with my situation. I have a P1000x1bd amplifier that has the “clean setup” and is equipped with led that comes on when the HU distorts, but this stays off consistently throughout the process. My guess would be the DD-1+ Is superior to detecting it over the clean setup, but like I said I’m not too sure, any insight helps. Thanks guys!
