Pioneer DEQ S1000A (Universal Sound Processor) 

You should use android 7 or below 7 android version phones. It doesn't work with android 8, 9, 10.

Exactly, with android it is a bit complicated you have to use OTG cables and not direct, and it disconnects a lot

Definately it will

Well, it has one sub out. You would connect the sub out to the input on your sub amp. So if your subwoofer amp can power the 2 subs that would be fine. And I assume you're talking about 4 component speakers? I believe it could handle 4 components or coaxials and the subwoofers. But you must have a sub amp. This does not have an amplifier for a subwoofer built in.

The Ad On sound processor can enhance the power of Speakers. However for subwoofers we suggest you get external amplifiers

This unit cannot power a subwoofer. But it has a subwoofer output, that you would connect to a subwoofer amplifier.

Yes you can..But phone must be connected to use this feature

Sumit Dudeja is pioneer going to launch more new models of dsp

Anyone face problem with USB connection? I'm using Android phone.

no

It is not a fail, it has a great sound I like it a lot, the problem it has, it is difficult to configure with Android, OTG cables if it moves it disconnects

@@rochulcr The product with problem is fail product . Otherwise it would be famous like old dsp player .
