Posted May 24, 20169 yr I recently had been in the market for a DSP, and ran across this pice of equipment. The PPI DSP-88r and some input from fellow car audio nuts. Is it worth the $209 bucks. Pros. And cons. Thanks in advance
May 24, 20169 yr I like it a lot, seems well worth the $209 price tag. People claim zero noise, which is a key point for a DSP IMO. Remote control unit is also very useful. It also has optical in. Found it for $175 on ebay. Damn, makes me mad I bought an Audison Bit Ten and I've just sent the second DRC in for warranty...
May 24, 20169 yr I'm using two of the Soundstream Harmony DSP's which are the exact same unit but with the Soundstream badge on them. I personally love them. Though they lack a few features found in more powerful DSP's such as the miniDSP, but they're super user friendly, noise free and are a great first step into the realm of digital signal processors IMHO.

The miniDSP is powerful but for me it did not work. Way too noisy, I ended up with all sorts of crazy attempts to fix noise. Now, they have a 2x8 for in-car installations, which I'm pretty sure has repaired the noise issues
June 10, 20169 yr using two 2x4 minidsp is also a bit annoying to tune when your switching between units. no noise issues if you use the dc isolator for me.
June 10, 20169 yr Admin The RF360.3 is a nice mid way option between the lesser expensive models and the Mosconi's for example.

I switched from the MiniDSP and can say that I am absolutely satisfied with it. it's not quite as easy to use as the MiniDSP but it has a lot more features.

What is it that you couldnt do with a biquad?? Did you test your minidsp out f your car? ....they arent noisy
June 12, 20169 yr 11 hours ago, ///M5 said: What is it that you couldnt do with a biquad?? Did you test your minidsp out f your car? ....they arent noisy Correct, I pulled the Mini DSP out and got a noticeable whine out of it, I tried even tried running it off of the USB power and it still put out noise. Not sure what happened because it just started happening after a few months of use. Sorry to clarify MiniDSP = very easy to use with every feature you need outside of more than 4 output channels. 360.3 = insane amount of features and a bit more complicated to use and takes some more time to figure out.
June 12, 20169 yr Still curious on the sonic features the 360 has the mini doesn't....my impression is the opposite but i havent spent that much time with a 360

June 14, 20169 yr like bluetooth and other stuff? lol .. I'm assuming thats where you're going with that On 6/13/2016 at 2:33 AM, Julian said: Audio wise you're correct outside of 4 channels vs 8, although I wasn't solely speaking about the audio features more of the other features it possess.

Exactly what I am asking. What features does it have that are useful? The 360.2 I had was super noisy and basically useless compared to a miniDSP. So much so I haven't considered one for anything and would generally have people run from it. I'd like to be educated if that isn't the case.

June 15, 20169 yr Ah, ok so nothing useful except multi source which for me is pointless as well. Thank you.

With the Pioneer fix on one of the amps, isolated DC supply for the phone and for the miniDSP and it still had some noise.
