So, here's what I've landed on with this:
The DSP (digital signal processor) that is built into the Autotech
rides on top of the Sync sound settings. If you have a bunch of stuff on that music app turned on like the app EQ... now you have three (or more) different EQ's running over each other. That's why you are hearing a drastic (and shiddy) difference in volume and quality when you switch out of Sync to a different app.
If you are running any music app on the screen besides Sync, these steps should give you a little better sound:
- Reset the Sync EQ to default (FLAT)
- Set the surround sound to "Stereo" instead of "surround"
- Make sure you have ALL EQ settings in ALLof the music apps you use set to FLAT or turn the EQ off in the app, if you can.
- Do this on ALL music apps on your device! Even if you aren't using them. Apple Music, for example, will f*ck with other apps sound because Apple is, well, diabolical.
- This goes for any of the other playback settings in the apps - Normalization, Loudness, Spatial Audio, DSP, Dolby, etc.... turn it all off.
- Now, go into the audio settings on the AutoTech and go to the DSP feature screen. Play with the settings in there until it sounds "right" to you. I will post pictures of how mine is set shortly. I will tell you, it's real sensitive!
- The Autotech, and probably the others from Ali, should have the source volume set to 25. That's where mine was anyway. I left it there. You can mess with it if you want. I'm assuming they did this to get the highest voltage signal they could into their DSP. I'm curious if that could be a way to override/trick the bass defeat (ahem) "feature" that is built into Sync/B&O that attenuates the subwoofer after the volume passes 15..... not sure on this and haven't messed with it. Yet.
Keep in mind, the Sync is completely independent of the settings in the Autotech. This means, if you play music from the Sync system (Sirius, AM/FM, etc) it will ONLY use the Sync sound settings. So, that music will sound FLAT because the Sync EQ settings are flat. If you use Sync for music often, that can be annoying. I don't, so I don't care.
Hope this helps! I'll post pics of my EQ settings in a minute.
