@mitchlampert It looks to me like the SHD (the SHD Studio's Big Brother) is the Droid you're looking for

(but at $1200)

In the 2x4 models,

The incoming analog signal is first converted to Digital to be processed in the DSP engine
(the ADSP12489 Digital Sound Processing engine appears to be the same in both models)
...That's where the BEQ magic happens, Then the signal is converted back to analog to your subs.

I can't confirm that the SHD Studio is able to accept an analog input via XLR and convert it to digital based on the supplied information.
(No ADC or DAC is listed in the spec) and even the flow chart diagrams indicate an external DAC (Digital to Analog Converter) is needed to output to speakers/subs.






You may want to contact miniDSP with your inquiry before purchasing
Glad to be moved up from utter moron status. We all have minidsp HD's and is anyone using the toslink to get their bass signal to the minidsp HD? Is that better? I don't like the idea of going digitial to analog and back to digital for dsp and then back to analog as that is a lot of circuitry in the path. But atleast the analog output (in most cases?) will provide the full analog signal derived from the 24 bit lossless movie. Toslink won't do that. Has anyone discovered a way to extract from HDMI the full 24 bit digital signal and go direct into a minidsp device? In theory they say toslink could handle 24bit especially if just one channel. This is all an HDMI protection issue which makes me ill and it would be wonderful to get around it and just bring perfect digital into a minidsp unit.

-The single digits are where the magic lies.....they deliver a 'touch of god' sensation that sometimes makes the hairs on one's arms stand up. It's hard to describe but it feels like you are there in the recording studio with the artist and "feeling" them move as they are playing the instrument. You can't see them, but you can feel them as movements are happening on the floor below you. - trhought

My thinking is the PB12 in the corner has a 6 db advantage so that gets it up within maybe 3 db of the much larger Monolith. The Monolith midwall about on a 25 foot wall would still get room support for the lowest bass. I believe with minidsp HD one could aggressively shape the Monolith to do all of that subsonic bass on its own. (My PB12 is 3db down at 21 hz ). If I wanted to beyond this I'm thinking buttkicker, boss, etc to vibrate the seat might all I can muster down the road. Or since I have just enough output with current subs try to do buttkickers with bass 3db down at 21 hz? NEED SOME BEQ subsonic advice as my finger is itchy to buy.
The monolith subs are nice if you're not going to go the DIY route. I have one of the 12" from before I started building and it's solid.

If you were anywhere near Ohio I'd take that Monolith 12 off your hands. If it didn't work out I'd run it in the corner with the 15!

I'm actually still using it. When I added in my 15" VNFs I had a big null around 40 hz that I was able to fix by positioning it next to my screen. It came in quite handy to keep around.

Just a friendly reminder to everyone that it's a really good safety factor to enable the compressor in your mDSP to prevent clipping its outputs.

To use it only as a safety factor but not have it alter the signal otherwise, you can use these settings:
Threshold 0dB
Ratio 50
Attack 15ms
Release 30ms

If all goes well it never gets hit, but it will step in as necessary if you send a signal that would clip the mDSP.

That reminds me, we had talked at one point about adding it as a merge option in BEQd and maybe having it defaulted to on. It might be time to revisit that idea.

This illustrates how little I understand the audio technology I'm using. I set it...though I don't know what it does or why it will help. So, off to do reading and research on miniDSP 2x4HD Compressor. The miniDSP instructions were a little helpful, but I'd rather see some more examples and in practice application. Always something more to learn. Thanks.

I'm assuming this would work in my 2.1 setup (MiniDSP 2x4HD) as well?

Thanks Aron, I actually meant to add this to the Setup Guide last year and never got around to it.
Just for clarity, this is not a global change and you would have to repeat that step for each of the 4 output channels
and for all 4 of the Config slots across the top if you use more than 1. (16 times if you use all outputs/configs)

I'm not 100% sure, but I think the compressor setting also needs to be saved into your output channel EQ/house curve "config file"
in order for it to be preserved when doing the merge with BEQ XML files in the BEQ'D App.

Thanks. Yeah, I read that in the guide I have for the 2x4HD. Still need to read it a few more times for it to sink in. I think I get the concept. I just don't know enough to even know I need to consider doing this. I can follow instructions like a champ; I want to get to the point where I know to just do this.

I just watched Predator and I have to congratulate Aron on the BEQ mix for it. It really improved the audio on that movie 100x over. That movie came out when I was 20 and I loved watching it, but the bass back in those days was essentially non existent compared to today. So watching some of those old movies today can be kind of sad to sit through. Until now, with BEQ they come to life like they should. Great job Aron.

The only part you need to understand is that is it makes loud sounds quieter, and in this case it's only quietening things that are so loud that they could damage your subwoofers


If you wanna know more about compressors, this video is quite good:

In this case, since we are only trying to use it as a safety factor, those settings tell the compressor only to kick in and reduce the signal as fast as possible (15ms) when it would otherwise clip the mDSP's output(s). Otherwise pass through the signal as-is.

So it will allow the signal to clip only as long as 15ms max before it clamps down and brings things back to a safe level. So consider the orange section below to be 15ms or less:

BTW, with BEQD, does anyone know an easy way of changing (in the signal file) where the wav file is? Or get it to default to say look in the current directory? I was wanting to move all my files to another location, but if the wav file is somewhere else than it was when the signal was created it doesn't open it. I tried opening the signal file itself but it is binary.

Do you already have a config file with sub EQ/house curve or both on your output channels?
If you do, that's where you will also add the compressor settings and just hit save to overwrite your current config.

Load up the BEQ'D app and do a refresh/merge and your Movie BEQ list will be good to go.

If you don't have a house curve or any EQ settings saved on your outputs channels
and only use the Repo to download BEQ xml files to your input channels,
then all you need to do is add the compressor settings to the output channels.


I've added this to the page 1 setup guide:

SAFETY FIRST

Open your miniDSP HD1 software and go to the Output tab,
Go to Config 1 and click the Compressor tab under Output Channel 1:
Enter the following values, then click off the bypassed button at the bottom, Done!

If you use all 4 output channels, you need to repeat that step for all 4 outputs
...and if you use all 4 Configs (across the top) you have to do the same for all of them.



If you use the BEQ-Designer App to merge Movie BEQ XML files from the Repo with your own EQ/House Curve
You want to include the Compressor settings in your house curve config.xml file

If you have a EQ/HC config.xml file already, you can Load your current config.xml, add compressor settings,
Hit the save button (top left corner) and it will over-write your current file.

If you don't have a config file yet, Hit Save (after adding the compressor settings)
Then create a new file folder on your computer to save your config file in,
... ideally a different directory than your Movie BEQ file folders.

Even in my scrawny dual pb12 system Hurricane Heist was nice; the BEQ definitely added a natural sound and just more realistic weight to the presentation. Another well done one.

-The single digits are where the magic lies.....they deliver a 'touch of god' sensation that sometimes makes the hairs on one's arms stand up. It's hard to describe but it feels like you are there in the recording studio with the artist and "feeling" them move as they are playing the instrument. You can't see them, but you can feel them as movements are happening on the floor below you. - trhought

Yup already did it. Only two subs and only use Config one so quick and simple five minute change. Thanks!

it's just gzipped, gunzip it and you'll find it is json and has a path to the file in it

the manual way is to open the signal and then use the waveform view to locate the file and then resave

Ah sweet. I didn't even think of it being a zip file, like docx, xlsx, etc

OMG, thank you for doing the homework I should have done! I'm not an engineer by any standard but you are quite right, the SHD Studio won't work in my system. Hopefully, miniDSP will allow me to exchange this.

I'm not an engineer either and those digital XLR inputs have me confused.
No problem at all and thanks to the work by the selfless folks here, I now know that the SHD Studio won't work.

I tried all sorts of shielding methods but the RF emission from my particular unit was so strong, it affected my remote's antenna which is 25 feet away!!

Unfortunately I can't individually tune each sub because I don't have enough cabling to run individual cables to each sub (for now at least!). I will look into running an additional cable. I didn't think that I needed to tune each identical sub individually since they are located symmetrically from my seating position.
