miniDSP Tide16 - Holy Grail with 16 Channel Atmos/DTS:X, high SINAD

Viking said:
For each channel it can be set i 1Hz steps between 1-1000Hz and be disabled (Full-Range).

That’s great news. I don’t understand why it’s always (more or less fixed) at 120Hz in other AV preamps/receivers. The LFE should already be low-passed in the mix. I don’t like additional filtering, as it might introduce phase issues when combined with (redirected) bass from the main channels.

I am really considering the tide as an upgrade for a 7.4.4 system. However I have 4 18 diy sealed subwoofers that require filters to bring down top end or bottom end up before dirac due to the natural response curve of relatively sensitive subs in a sealed enlcosure. If I dont dirac rolls them off far too early even though they are capable of very good infrastonic bass. Is this possible to do in the tide16 so I can take the minidsp out of the chain?

That’s exactly what I’m doing with my subs.
For my Procella P18 sub (2 x 18” sealed) for example I have a Low Shelf filter, two PEQs and a BW24 HPF set up in the Tide16 making it essentially flat down to 14Hz, -3dB at 12Hz all done before running DLART.
And it’s preserved with ART activated. Although ART itself only corrects down to 20Hz.
 
I use an HDMI to I2S to 4x I2S to AES and get out DTS HD Master 5.1 with 192kHz So at leased 7.1 in and 4x AES Out capabel off 192kHz for under 150€ DIY
(LPCM)

The only thing thats not work this way is ATMOS Rendering to 16 Analogue Chanels Roomcorected with DIRAC But for me in an smal Apartment no way to place 16 Speaker full Aktive anyway LOL

Already 7.2 aktiv System is an Chelange in an 15 m² Room ;) .........

Next step is Building an aktive fully Digital Crossover with an RME HDSPe AES 8x8 Digital in and out to 8 DAC SMSL SU-2 (16 Chanels Analogue OUT) (On a PC and also Experimental on An RPI5 with PCIe X1 Adapter, Card not arived yet)

On the other Hand my HDMI 7.1 to RPI 5 to 2 MOTU UL 5 (16 Chanel out) works fine already with CamilaDSP ;)

Sure not the right way for People with an big fancy Private CInema in an owned House with Money in his Poket.

But for me the MINIDSP TIDE 16 with internal 48kHz only Processing (no FIR Filter) isn't worth it at all but i guess this Restriction is because off licenses and so on also Copyprotection stuff. Not MiniDSP fault.

ARVUS nore Nuprime X 16-AES gives AES Out with more than 48kHz Out :(

Hyperion DPR-16 i can't find Information about AES Out for now.

So there not much Surroundprocessors with AES Out i could use without that Resriction :(

The Project is described here, for People that interest in some DIY Stuff. But this Project has Started right now so there is a chance it won't work this way ;) :

https://www.diyaudio.com/community/...or-full-surround-digital-aktive-setup.440807/

If anyone knows an Surroundprocessor that capabel do get AES 7.1 (96kHz at leased) out, please tell me.

Did you see this update on the miniDSP forum:

”Pay no attention to the "No action required at this time." message at the bottom - it's a trap! Call FedEx immediately at 1-800-463-3339. Say "Clearance Delay" when the automated system asks what you're calling about, which will cause their system to automatically route you to their international shipping department. One of their reps will send you an e-mail containing a DocuSign link to CBP Form 5106, where you can securely provide your SSN or other tax/importer ID info to US Customs. This e-mail may take ~24 hours to arrive. The only field on the CBP form that isn't self-explanatory is the "Title" field to the left of the signature block at the bottom of the form - the correct input for this field is "Importer". If CBP wants to see your invoice, you can provide it to them by attaching it to an e-mail addressed to "[email protected]" with only your tracking number in the subject field - this will auto-route your invoice to the FedEx logistics person handling your case, who will in turn provide it to US Customs. Hope this helps someone.”

I don’t know whether this piece of advice is valid for you but maybe worth investigating.
 
I did not recieve the message:

After having watched some movies in 4K, Dolby Vision with Atmos and listened to some music I’m impressed with the quality of playback through the Tide16 and consider it a definite upgrade from the Anthem AVM60 I hade before. Dialogue is clearer and music sounds better. Hard to say if it’s because of better processing or DACs though.
There’s however a few improvements I’d like MiniDSP to implement down the line and I hope this product continues to develop further.
I wish that all HDMI inputs, not just the HDMI/ARC output would respond to HDMI-CEC commands so that the volume could be changed from any device connected to a HDMI input like an AppleTV etc.
I also wish that each of the four scenes could use Dirac individually so that you could have a scene without Dirac and full customizable PEQ control since PEQ is locked and can’t be changed after Dirac is enabled.

Dirac Live with Bass Control or ART will low pass filter the LFE channel at 120Hz.

And the LPF of LFE can’t be altered afterwards?
Only if Bass Control or ART is disabled?

All true. However, they recently announced that they plan to make this optional.
 
I can see the advantages...consistent Dolby-compliant behavior, predictable optimization, and protection from unwanted content above 120 Hz while tradeoff is filtering and phase rotation. With Dirac now planning to make the LPF optional it will be interesting to see measurements comparing ART with and without the LPF.

I am very curious about the number of filter taps used in Dirac Live ART:D
Click to expand...

1. State the DSP device.
2. Look up the spec sheet. You are looking for what DSP chip is used. It's usually a SHARC ADSP series chip.
3. Go to SHARC's webpage and look up how many FIR taps / IIR biquads that chip supports. ART will not be able to use more than that.

I think removing the LPF may cause the PAC devices some issues as it will re-introduce the Linkwitz-Riley vs Butterworth crossover slope mismatch.

Anyone know what I'm talking about?

1. Notice what thread you are replying in.
2. Then notice there is no SHARC chip in Tide16.
3. Ask in the the Tide16 thread hoping an early adopter will share what they are seeing in Dirac Live software.

It's a quad-core ARM processor (1.8 GHz) in the Tide16 so hopefully an owner will let us know soon.

Sorry. I open multiple tabs in my browser and did not realize I was in the Tide16 thread, I thought I was in the ART thread. The Tide16 has a quad core ARM processor, it should have plenty of DSP grunt. Enough for an all-FIR filter set if that's what they wanted. But I know that Dirac prefers to use mixed-phase DSP, they do that on their PC version. So - I don't know how many FIR taps it uses. I can't seem to find a manual on MiniDSP's website.
 
I think the question is about ART "cross terms" not FIRs. Available cross terms is the thing that limits how many ART support channels can be active. Denon/Marantz has only 94-98 cross terms and for 16+ channels you need over 200.
