Please elaborate on the optional DC Power Supply. Cost? Format?

Wrong wording on my part which I can see could lead to confusion:
miniDSP 2x4 comes in 2 versions: One with USB power only, one with DC input and USB input. The DC input is on a 5mm, Phoenix connector style terminal block and PSU is to be provided by end users (not included in cost). It's basically designed for those of you who want to use their power supply vs a DC supply.

After running many tests on the Audio Precision with different USB chargers and external DC supply, we couldn't see any major difference on the specs of the board. Hence the reason that we don't have any real needs for recommending an external supply since it doesn't seem to add much to it. In the mean time, we can understand those of you who prefer it, so we still provide it as an option.

Hope this makes sense,

Thanks for the clarification. My future plan is to incorporate a minidsp in each of my powered OB Speakers. One channel for permanent cross over, the other for experimental configurations. As such, I need to power the units externally.

Neat project! Keep us updated with your progress. The DC input option can be selected as a free option at the check out process.

Hope this makes sense,

hi, will this be suitable for FULLRANGE OB + H-FRAME OB WOOFER?

i m going to bi-amp the setup, so the miniDsP is like x-over from computer?

pls explain more thanks :D

miniDSP is a digital crossover, so if what you're looking for is a crossover, with Equalization and time alignment, then yes miniDSP would fit your project.
Have a look at miniDSP forum for an example of a open baffle project. Someone already used it for that matter.

I'd recommend that you have a read at our website. It's literally full of information, application notes, projects by the community. Can't think how you wouldn't be able to figure the information you need.

I have a question.. and by the way love this little wonder you guys are building..

can I asign L or R only output per channel?.. So with this new 2x4 or raw board I can verticaly processes them?

Hello Randy,

Thanks for your positive comments,
Not sure I fully understand what you mean, but I guess that you want to control the routing of input 1 to certain output. Currently, the easiest way to do so would be:
- using the 4way plug-in, you'll have a 1x4 configuration where you can select the Left OR right input.

or if you need more flexibility,

- using the mixer plug-in, you can really decide which input goes to which output. A true matrix mixer.

Hope this answers your question,
