I just picked up a 8 channel DSP with bluetooth control for 104 bucks shipped from Amazon.
Going to do some testing to it when it arrives here maybe Friday.
Amazon.com: EXPERT 8 CH 15 Band EQ 3 PARAMATRIC EQ (PX8.2CONNECT) : Electronics

Most of the stuff is in Spanish. There is ONE english review I have found on it.
So... Guess I will send it to Amir if anyone wants an in depth.
App is here if you want to give it a test run

There is a
ENGLISH video I found.
Price is 104 Green Bucks.
And lucky for us, the dude also made a ENGLISH manual!

Here is the Video of the App BEFORE the requirement* to be used on a GPS Phone for some reason?
I can't get it to download for my Chromebook, However, there is an APK that is out there that will allow you to run this native on development mode. And I think there are older versions of the Apps as well to use on older tablets just like in this video.
All support it seems is from WhatsApp... Or Maybe Email.
Unit has been out for about 5 years or more now, so it seems like the hardware is sound. Not sure about the parts inside.
App seems to be Native in English Language...But everyone is Spanish??
OOOKay!
Quick Technical specifications:
- High Quality Digital Crossover (Well it better..)
- Excellent Functionality and Cost Benefit (No argument there for 8 outputs)
- Simplified and Accurate Commands (Easy to use?)
- Has 28 Equalization Frequencies (I think per channel)
- Gain: -18dB / 6dB (Stock gain is to high, so it has hiss turn down gain from what I heard)
- 8 (6) Customizable Channels (8 channel and 6 channel model available)
- Input Impedance: 47 kOhms (For smart people to figure out)
- Output Impedance: 100 Ohms (For smart people to figure out)
- Sampling Frequency: 48 kHz (16 bit??)
- Hi Pass and Low Pass filters: 20 to 20 kHz (seems good)
- Display with Light in Blue Color (Setup can be done on device locally without app)
- Attenuation Filter: 12, 24 and 48 (dB / 8th) (Dream come true for tweeters i would think and Dome Midranges)
- Approximate Dimensions (AxLxC): 30mm x 240mm x 120mm
- With Control Through Tablet or Smartphone Application * (As long as your phone has GPS is seems)
Application & Benefits as I see them.
====== It seems like this would be best to be bought in Pairs as now you can run a FULLY active system with rear fill & since they are so inexpensive? Its not going to break the bank Perfect for the quick plug and play hobbyist till you are ready to step up to some ubermensch processor.
There is a good guide on Rear Fill on Car Audio Junkies
Here.
And on MiniDSP
Here
What I am excited about? First the price!
The second is that I can now test out speaker drivers to my heart's content!
The fun of this processor is going to have an easy 16 channels to work with for around $208. You may have timing issues, but I don't see that being a problem that should pose much of a problem for me as I plan to run the other channels with Tactile transducers, and stereo subwoofers, and active rear fill.
as it is I really do like a set of tweeters but I've always liked to also have a scent of super tweeters or tweeters with a bit more Sizzle in the top-end being placed at a different location to give the soundstage more depth.
Using a system like this below but adding a super tweeter or a dome midrange would take up 8 channels alone.
So basically a front active 4 way system.
With the addition of
Not accurate, but you get the idea.
It also opens up the idea of testing drivers at home making it a Simple process. But since it is the Holidays?
I plan on using this little guy for doing some sound effects outside. With 8 channels, I think I could get the dealy so that when people walk up, the sound will carry down like an echo in a hallway or how sound travels with delay if you set it up right.
I already orders some Philps Hue lamps and a Halloween lighting app that makes sounds. Add a motion sensor, and I can have the lights work with this unit, Via all the AVR's I got, and then make them work in conjunction with the fog machine and Laser projectors.
Anyways, wanted to let you know about it since its a fantastic deal and its easy to work with and seems to have some good reliability.
