They have an array of boards to choose from. The most basic is an all analog DSP board, called the miniDSP (which this review is based on).
MiniDSP - miniDSP Kits
Note there are two versions of this board:
Rev A = 0.9V input
Rev B = 2.0V Input
For car application, you’ll want the Rev B version if you have a headunit with a high pre-out voltage. Otherwise you’ll clip the inputs. This may seem like a huge concern when looking at the numbers, but read the “Concerns” section of this review to see my findings on the matter.
hi erin,
re-read all your post and the minidsp website. in fact i also emailed their support team. and you're right i think all my questions were answered by your first post. but anyway, i still have a couple questions:
1. regarding which board to get. it says in their website:
This board is a RevA version with 0.9Vrms input capabilities. It is the perfect fit for PC sources, portable players or any source capable of lowering the signal to this level. If you intend to connect it to a CD player, or any other source which you don't have volume control over, you should purchase the RevB version instead.
since we're hooking this up to our head units with volume control, it kinda conflicts with your post that says for car audio applications we should use revB. im not trying to argue with you. just want to clarify buddy.
when i emailed minidsp here's their reply (btw you're right they do answer promtly

)
Which kit should i get for car application? revA or revB?
*Answer*: It really depends on your signal. RevA is 0.9Vrms maximum or 2.54Vpp. Most head units show Maximum Vpp so do some research to figure out what device you will be connecting it to.
so with their reply, i guess you're correct in choosing revB because it has a higher Vrms rating right? im just conflicted with what is posted on their website regarding boards vs. volume control sources.
2. regarding plugins. i wanted to have both parametric and the graphic 31 band eq but this is their answer:
You can't have 31band EQ AND parametric. It's all very clearly detailed under the plug-in diagrams(
MiniDSP - MiniDSP Pluggins)
i was just wondering if you were able to have both? if we really cant have both i guess the best route is to go with the 31 band graphic eq right?
lastly this is for all those who want a 4 way full active set-up, this is what minidsp recommends:
parts:
2pcs. miniDSP for 4 way: 1 x Left, 1 x Right
1pc. 4way Graphic EQ plug-in if you want graphic EQ OR 1 x 4way PEQ if you want PEQ.
here's another interesting discussion between minidsp and i regarding connecting the sub:
Question: i can still hook up my sub from the head unit to my mono amp right? bypassing the minidsp kit?
Answer: Yes, that's not a problem, you just need to remember is that you'll have to time align your system. So bear in mind that you want to get your sub in line with your miniDSP + internal processing delay.
anyway just really want to make sure before purchasing this product. sounds very promising! thank you erin for discovering this for us.
