Alpine PXE-08505s feedback

I do still like it but am experiencing some strange behavior that might be operator error or something not working properly with the bluetooth in the dsp or Fiio9. I got it to work a couple of times previously but last time I worked on the car it wouldn't connect. Next time I troubleshoot I'll test the coax out too. Better quality that way anyhow.
I also haven't seen where to mute all but one speaker, which is nice to be able to do when tuning. There's a cumbersome workaround (lower the output of every other channel one at a time) but they really need to add that. I haven't had tons of time to tune so I'm a long ways from finished.
 
Its so they didn't have to create a separate terminal for the power and ground. They provide 3x 18 gauge wires to accommodate a larger gauge power wire either from your battery or your distribution block. I plan on running an 8 gauge power wire to the unit. Yes, I'll have to solder all 3 wires together than to the 8 gauge with a good quality connector. Same thing for the ground.
 
Played around a bit with phone and Fiio bluetooth playback. Good news is bt works fine- both devices will connect quickly. Only one bt device can be connected to the dsp at a time so no real time tuning with Fiio via bt. For some reason my wired remote does not work :(
 
Syncher,

Is there a setting that needs to be turned on in options or set-up for the wired controller to work??

I'd contact Alpine USA support for assistance.

That's great news that the BT is working well!

No setting or option listed in the manual. Here is the only and somewhat vague instructions for connecting the wired controller:
Before using wired controller, connect the wired controller to the main machine and ensure that software or app isn’t connected. Connect PXE-0850S wired controller to PXE-0850S machine and power on properly.
So there's a main machine and the dsp machine :ohwell: There's only one way to connect the wired controller to the dsp so that isn't the problem. I always turn the power on with the controller plugged in and with no software running, and no laptop via usb or bt device connected. The manual then goes on to describe the various functions the controller does. Unfortunately, mine never changes from the powered-on screen to the functions screen- it should do that automatically.

Edit: usb cable was plugged in backwards. The installation manual states that it only goes one direction but the user manual doesn't. So all is well :)

One other thing to watch for when you're tuning- the output of the head unit doesn't match the Fiio (I suspect it won't match a cell phone either). That just means we need to adjust the gains for the bt device as well as the head unit in the mixer section of the dsp software. I tried using the same gain settings for the high level input and bt they're not close.
 
Well, have the unit installed. I notice there is a difference in output when running through the controller versus the blue-tooth/smartphone application. The controller volume goes up to 66 but only 60 in the app. Really strange. Once I close the app, it will say 60 as max volume on the controller, from which I can then turn back up to 66. Odd...

Another oddity is when hooked via blue-tooth, if you're not careful, the volume will come through at max volume and can only be adjusted through the app or the controller if the app isn't opened. Adjusting the volume on the OEM source WILL NOT decrease the volume. This scared the heck out of me the other day when my phone began playing a song via PowerAmp.

Also, it would be nice to have the ability to EQ on the input side, not just the output.

Overall, the unit is pretty solid and I'm having no problems understanding how to control everything through both the blue-tooth application and PC software.
 
UPDATE!

Been using the PXE-0850S for about 9 months now. I can honestly say the thing works! I've had no issues running either digital (toslink) or aux (RCAs). The unit is easy to adjust on the fly using the Android app, connects to bluetooth quickly, and doesn't have any issues with noise!

Whoever is on the fence, this is a good DSP. It does lack some of the features like input EQ and variable phase (only 180 or normal), center and rear processing, that the Helix devices have, but for the money, it's a good way to enter into the world of DSP tuning!

I will say this, the onboard power is not that strong and should only be used with stock speakers or efficient tweeters. That being said, I like my purchase!
 
there should be enough channels to loop an output to an input, effectively giving you "input" eq :)

however this only works for analog interfaces.

Which way is considered backwards? I installed mine with the usb to the unit in the trunk and the split end inside my car with the controller by the dash. Is this correct? Or should the split end be coming off the unit?
