I'm about to order a pair of balanced 2x4 units. On the MiniDSP site they offer the option of including a power supply, but since I'm in Canada and ordering from Solen.ca, I don't have that option. Based on what I've read in this thread and elsewhere, it seems that for the balanced unit I'm looking for a 12VDC 150mA power supply. Is there anything else I should be looking for? The MiniDSP devteam stated on their site that "12VDC 5A is more than enough and will work perfectly fine. The 150mA is only a recommendation for the minimum. Higher amperage is better." I assume that's legit, as long as I maintain 12VDC?

I'd hate to go to the trouble and expense of setting this up just to have a poorly selected power supply introduce noise or damage the unit.

I think I have also seen some units with an actual power socket, and some with the terminal block type. Does anyone have any details on what size the plug should be? I've seen barrel sizes around 5.5 x 2.1 mm; 5.5 x 2.5 mm; and the smaller 3.5 x 1.8 commonly.



EDIT: I just had a reply from Solen (very quick, actually), and they recommend this power supply. I don't mind spending $16 on it if it looks like it will last without issue. Thoughts? I remember reading a bunch about having protection built into the PSU being important, and it looks like theirs has it.

I didn't see the power supply option at the miniDSP site for the 2x4. Madisound still has it for now. I think most people are just using old phone chargers since a lot of us have a few laying around collecting dust. I would have gotten the PS had Partsexpress had the option.

I ordered the recommended ones from Solen, just to give myself a little more assurance that they won't go poof.

I'm going to use a high joulel surge suppression power strip for all my electronics. Got a dual USB slot plugin fast charger for my old Samsung phone. Glad we have options

So going back to my question on the previous page, I have attempted to get a response on the MiniDSP forums to no avail.

I am looking at utilizing a MiniDSP 8x8 with the DA-FP. The DA-FP provides S/PDIF and TOSLINK inputs, which is not really a huge thing to me, though it does mean for critical music listening I can bypass the redundant DAC on my Marantz SR5010 and simply run TOSLINK in from my ASUS Xonar STX. One less conversion in the signal chain can't hurt.

The main reason I want to use the DA-FP with the 8x8 is that it also provides 2 XLR analog outputs, which would be perfect for adding subwoofer control.

Looking at the product data sheet for the DA-FP it seems to suggest it is compatible with the 2x8, 8x8, and MiniSHARC platforms. I have attached the DA-FP datasheet.

However, what has me concerned is this question posed on the MiniDSP FAQ page: http://support.minidsp.com/customer/...-kit-and-da-fp

If this issue was a few years back, I would have thought they fixed the problem, since the DA-FP datasheet still says it is compatible with the 2x8, but the date on the question is April 2017. If the DA-FP has issues with the 2x8, does it also have issues with the 8x8?

If it is compatible, I am assuming I would need to use the 10x10 plugin in order to get the extra input/output options in the software? However, when watching videos showing the 10x10 plugin, the extra outputs are labeled as 'Digital Output 1 and 2'. I assume this is because the 10x10 HD hardware uses the DIGI-FP which has S/PDIF, TOSLINK, and AES/EBU outputs instead of the XLR analog on the DA-FP. When the DA-FP is used, are these switchable to 'XLR' or 'Analog Outputs'?

Does anyone here have experience with this combination or any thoughts at all?

Thanks for letting me know I am not just talking to myself!

I actually already have a thread on the official MiniDSP forums, here: https://www.minidsp.com/forum/hardwa...-8x8-and-an-fp

I initially was interested in using the AN-FP, based on the I/O expansion possibilities, but they apparently never got around to adding the functionality into the 8x8 firmware. After they shot that idea down, I decided the DA-FP would also work for what I am thinking, and it adds some extra digital input options as well. If you can't tell by a couple of the posts, I am pretty frustrated with their lack of responsiveness on the forums. This is a common opinion in a lot of the postings. Some of the questions go unanswered entirely. It's looking more and more with each passing day like they are going to ignore my question until I just go away.

I realize this combination is not widely used, but it baffles me as to why it is not more common. If I was doing 7.1 channel DSP, the ability to have 2 more analog outputs would allow a 7.3 set-up, which is not rare at all. As active DSP crossover networks become more accepted by the stuff shirted audio snobs (an uphill battle I know), more and more people will be looking at using their existing gear with a unit that will allow future expansion possibilities. Most of these people are using amplifiers with analog I/O, not pro gear set up for digital input. Besides, most pro amplifiers with digital I/O are starting to incorporate DSP into the amps themselves, and will have no use for a MiniDSP type unit.

It just seems to me that MiniDSP should be working on expanding their analog I/O line-up a bit more.

But I digress, I am typing too much again...

Most people wont respond if they cant help. Honestly, I think their silence at miniDSP should give you your answer. I agree their interface is clunky and the way they come off is somewhat different at times. I chalk it up to cultural differences and different way of doing business.

I grasp what your trying to do, but cant give you any help in that regard.

Considering they state in the DA-FP product brochure that it is compatible with the 2x8 and 8x8 platforms, then in the FAQ an actual buyer states that the 2x8 is not compatible with the DA-FP is worrisome on all accounts, and should be reason enough for them to give a response one way or the other.

All I need is a 'Yes, it is compatible, and the plugin will handle routing in the same manner as the other analog outputs' and I'll push the PayPal transaction through. It shouldn't be that difficult.

If the answer is 'No, our best attempts to incorporate the DA-FP into the 8x8 firmware and 10x10 plugin have not been successful. Our apologies for having incorrect information in our product brochure.' then I will get a balanced 2x4 to go along with the 8x8 and figure out how to power them both with one power supply. I have enough power cords to strangle an elephant already!

It sucks that they dance around things instead of shooting straight.

Silence is not an acceptable answer, just ask my girlfriend!

I bought two miniDSP 2x4 units. Can you use the same mini 2x4 app for both units to set them up?

Yes, the plug-in is not tied to any specific serial number.

Awesome! I'll buy the 3-4 way advaced plugin while I'm at it.

If I get a miniDSP 10x10, do i need to get the Phoenix to Male XLR to be able to use it with amps like the SpeakerPower SP2-12000-HT?

Do they send 10 Phoenix to Male XLR cables? Or? I'm confused on that...

Thanks!

I'm trying to confirm which plugin to use for the MiniDSP 2x4 (balanced) for my setup. Receiver with 2 LFE outputs will be fed in some manner to the MiniDSP which will be distributed to 2 front sealed subs that will be EQ'ed, and also to a Buttkicker LFE setup.

I've read the guide by @AustinJerry (thank you for that!) and I think what I will want to do is use one of the AVR's outputs for both subs into a single MiniDSP input. If I configure all of my EQ to fix nulls, set up a house curve, and fine tune distance before running Audyssey... does that mean I can then use the second sub out (directly to the BK amp, bypassing the MiniDSP) for the Buttkickers and theoretically have less processing applied to them by the AVR? (@asarose247 is this how you have yours set up?)

The plugin recommended in the guide (and recently to Cichlid109) is the 4 way advanced, so my very long winded question is: is this still the best plugin for my application? My unit came with a coupon code for a free plugin, so I want to make sure I use it on the right one.

I think I'll have to run Audyssey before enabling the 2nd sub out and connecting the Buttkickers, because unless I'm mistaken, Audyssey would attempt to calibrate it and not have any audible feedback to work with, which I'm assuming would be bad.

Do not apply the house curve before running Audyssey because it will try to flatten out your house curve.

You can effectively reverse Audyssey's EQ on the subwoofer output in the MiniDSP for the buttkickers if you want. You'd just connected the output from the MiniDSP to your USB audio interface and sweep the system with REW (HDMI in to your receiver in the LFE channel) and have REW calculate the filters to flatten it out and apply those filters only to the output correlating to your Buttkicker amp.
