Erin - maybe a dumb question because I missed it - It is USB powered, one USB input, and you are using the adapter to power it. I assume this to be that when you want to tune you unplug it from the power adapter, plug it into the laptop (which powers the USB) and make your changes, then unplug it an put it back in the adapter, which then powers it again?
Is there another way to power the unit, other than USB? If not, it seems this would require a HTPC set up in house to work - or a phone charger adapter or something. Or is there some kind of other power adapter as well?

Yep, that's how I chose to do it for simplicity.

Yes, you can hardwire it as mentioned in some part of my novel.
The board comes with the female adapter end. It's a 20 pin type socket IIRC. You can order the male adapter, wire into the male adapter, and have a plug-in harness.
Just as an FYI, for anyone who wants to copy what I've written in this review and paste it on another site, I would at least like the credit when you link it. You don't have to provide a linkback, just give credit to the author.
It's not like I think I'm king shit because I can type. It's that I spent 2.5 hours typing this stuff up, taking pictures, and trying to document the steps and my thoughts on it. Copying and pasting my write-up without at least giving me credit, in my opinion, is kind of crappy. Just sayin'.
*you know who you are. I will not discuss the matter any further.*
Damn these things seem to be really sweet, Especially at THAT price point... I think I may have to give one of these a shot and make a nice little plexiglass box for it
Thank you for the excellent write up. As a newbie this seems simple enough to setup. I've been wanting to go active for a long time but other options seemed to costly or too complicated. I will be starting with a simple 2 way set-up so I will only need one unit.
I'm a little confused (and I know you're probably tired of all the questions but my curiosity is killing me). I have the 880prs running a 2-way+sub system. Say I run the rca from the "mid" on the prs network to one of these little miniDSP guys, could I effectively use and tune both a midrange and midbass from the miniDSP and tune the tweeter/sub from the 880prs? If so, my move to a 4-way system just got about $500 cheaper.

My guess is, each unit has a delay of signal in processing signal out. It's why Andy W of JBL says you need to let the MS8 do bass management. because of the delay.
So your pioneer has a delay due to processing, the Mini most likely has a delay as well. It may or may not make a difference. Especially when you daisy chain processing units of different manufacturers.
Alpine 9884, C701, H701
Dayton RS225,BG Neo3,BG Neo8, TC 3000 15 DVC
Sundown SAX 100.4D X 2,Sundown SAZ 1500D

Should make a huge difference since the delay is on top of whatever the head unit takes to do its DSP.
Latency indeed depends on the plug-in that is loaded and the filters enabled as you correctly pointed it out. 1.09ms is for the stereo 2 way, including ADC/DAC path.
The latency is indeed fixed once the filter enabled. You could expect that by enabling LR filter (4th order) you would get up to 2.5ms or so once again from ADC to DAC.
Hope this makes sense,

2.5ms= 33 inches
Edit: Although, if you can delay the tweeter and sub channel by that amount and still have enough delay headroom for the normal T/A'ing, you can put all outputs back in line with each other.
If you're talking numbers only, then I agree, you have a problem. But, since you're setting up time delay on a relative scale based on what you hear, I don't see the issue. At the end of the day, you're going to make changes to your system so that you get the desired result. The overall delay of one component will not effect this because you're tuning manually. The only problem I would see is if the initial delay was so far beyond what the other outputs were capable of matching, that you would never be able to sync drivers up. Ie: Your headunit delays your midrange/midbass by 30ms, and your other source of DSP doesn't have the ability to 'catch up' to this. This isn't the case here, though.
Maybe I'm wrong, but I just don't see an issue here.
Since I'm starting up a home audio project I decided to bring the miniDSP inside the house and set it up in my computer room. The future setup will be a set of bookshelves... yadda yadda.
Just wanted to share a quick 'enclosure' I made for this with some scrap perforated aluminum and ABS plastic.
And a couple shots of the computer room setup with my new adcom four channel that will be used to power the bookshelves. the miniDSP will be used as the 4-way splitter so I can figure out what crossover and levels works best for that setup.
So, beyond being great for the car, it's a dang cheap way to test drivers before building the passive crossovers.
Sweet! It looks like it'll be a nice setup. Love the perf alum. Paint all of the hardware black ftw. I also love your monitor stand. I've got one just like it.
But no DIY bookshelf speaks?!? I'm confused, son. I'm sure they'll be coming soon enough.
Pick yourself up a "Logitech Lighted Keyboard". It'll go perfect with the rest of your setup and it's the best keyboard you will EVER use! I've tried them all, including all of the Mac k'boards. The Logitech has White LED backlit keys with 3 levels of brightness or you can turn them off. But that's not why I bought it. It has the best feeling key action you will ever try. It's also sealed and very durable. Thought I suggest it since you do A LOT of typing on here, lol. Trust me, you'll love it as much as your 12M's. It's got the heft of the SS build quality as well. Just get one. Your fingers and hands will love you, haha.
We need to talk about your wiring skilz, tho! Haha. Clean that up, boy.

I'm planning on picking up a miniDIGI at some point down the line, too. I'd really like to stack a miniDIGI and 2 miniAMPs. That would be a sweet little setup, but the drivers I use all require more than I can get out of a miniamp. At least in regards to using them in a listening room where I'm further away from the speakers, which is a project I hope to start on early Fall.

Maybe a miniDSP and 2 miniAMPs per speaker in an open baffle or high efficiency setup.
