They do have an 18gbps board coming out and I'll wager it'll smash the NAD too. The MP50 is right up there with the best of them and gets good results consistently. I've heard them in several different rooms now with the same speakers (more or less) and it's as good/better as everything else I've heard.

Giving up DTS:X seems a bit daft, Auro, sure there's not much going on there in the west.
The limitation is purely in my head, as I don't want to spend $ on a processor without working 18gb chips, lol. I'd rather have a solution "on deck" if / when I need it. And, yes, I've heard good things about Room Perfect and would like to give it a shot.

As for giving up DTS:X, yeah, that's a bit annoying. Unfortunately, though, I don't have heights at all right now, so...I'm really not giving up anything.

Honestly, all of these processors are more than I need. At best, right now, I'll have a 5.1 system using phantom center. But, if I ever get to finish up my basement space better, I want to be prepared. But, I don't want to overspend on preparation because even then, likely 7.1.4 is the best I'll ever get to.

Of course, if anyone wants to send me a demo MP-50, I'd love to try it out! Else, I'm willing to pay for it up front if there's a good return policy, lol.

However, there aren't many Dirac units around to chose from, so if one wants to try Dirac as I do, it's probably one of the better contenders. The Arcam / Lexicon units are another, but I don't like being limited to a single crossover setting for all base channels.
I’ve had the same issue you do- trying to find a good, sub 10k dirac processor. I ended up just going with a Marantz 8805, though do have an eye on the RMC release.

I considered the Marantz unit and toying with the Audyssey app, but decided I don't want to use Audyssey again this go-round.

edit: Looks like you've had and sold both the Lyngdorf MP-50 and the NAD M17v2. In fact, I may have even talked to you about the MP-50. Care to share your thoughts (if even via PM).

MP-50 LFE vs AUX, Dual Subs Diagonally Positioned

I just installed my MP-50 this week and I'm adjusting the overall system. Dual subs have been heavily discussed...but I'm hoping for further insight from others more technical than me.

My subwoofers are positioned diagonally in the room. The front sub is about 2' closer to the primary listening position than the front sub. Moving my subs around the room is NOT an option - very limited space - no need even suggesting it.

I have been working with SVS, my Dealer and Lyngdorf to optimize my setup - with varying opinions.

Current Setup:

- My two diagonally positioned subs are connected to the MP-50 AUX 1 and 2 outputs (MP-50 LFE output is not used)
- The idea behind using AUX 1 and 2 is that this configuration would better accommodate the unequal distances of my subs from the prime listening position - reducing phase issues.
- All my speakers are set to M Medium (80Hz cutoff frequency)
- Lyngdorf says "With a diagonal subwoofer setup you can operate in Mono only". They strongly suggest I use the LFE output with a Y Splitter - but they acknowledge there may be phase issues given subwoofer placement. I have not tested this configuration yet.

Are there other individuals like me that have two subwoofers that are diagonally placed in the room that are unequal distances from the listening position? If so, how did you handle the setup?

Thanks!!!

My Equipment:

- MP-50
- SVS SB16 Ultras (Pair)
- B&W 803 D3 Front Speakers
- B&W HTM1 D3 Center
- B&W 804 D3 Rear Speakers
- SVS Prime Elevation Speakers (not installed yet)
- McIntosh MC452 (Front Speakers)
- MC205 (Center, Rear, and Elevation Speakers)
- Oppo 203
- PS4 Pro
- Sony 65" Z9D

I have the same exact setup as yourself. The distance is about 1 foot between the two subs. I have the two subs daisychained to the LFE and the distance is set to the closest one. I typically use REW to find the sub delay and add that to the distance but I’m currently having trouble with the REW program.

Using the Aux 1 and 2 in this case will be strange since the MP-50 will matrix the subs with the other speakers assuming it has two (or four) front (+ back) corner placed subs. So the better option is both subs on the LFE output (either a Y-splitter or actually you can just daisy chain the SB-16s) in this case. Then if possible, I would use REW to measure each sub individually first, and then in combination, and use phase adjustments (on the closest sub) to try to reduce cancellations and make them add up as "one". Actually, a slight difference in phase between the two subs may sometimes be beneficial even, to reduce seat-to-seat variations, as explained in depth in the Multi-Sub optimiser tool (https://www.andyc.diy-audio-engineer...tml/index.html). In any case, finally I would set the distanse to the back of the sub furthest away before running RP.
And if that does not suffice (but I think it will), you can get an external DSP (e.g., a MiniDSP) to tweak the integration between the two subs even further, before running RP. There is a great tutorial by AustinJerry on how to do that, including aligning impulse response etc: https://www.minidsp.com/support/comm...ered-tutorials

Is this always the recommended general procedure to measure sub distance? and LFE?

The general recommendations are a bit vague I think. Really, the VERY best way to set the sub distance in cases like this one is to check with REW and using one of several techniques (impulse response with accoustic timing reference, etc).
But I found that I can get very acceptable results by simply measuring the distance on the *BACK* of the sub, or if it is in a corner, measure the distanse to the corner...
But in this particular case, where there were two subs of slightly unequal distances, and where you first tweak the phase of the closest sub to align the two subs, then I would enter the distance from the MLP to the back of the sub furthest away as the "LFE distance". That's just my experience/opinion in for a special case like this:-)
I've also experienced that it may be an advantage to let the woofer face the wall and not forward.. but opinions differ on that. That could also be a way to reduce the difference in distances between the two subs...

Nicely done.

I use a DPA-1 and noticed that the bass extension was different before/after using RP. I never thought it was an RP issue.

The loudness contour thing you measured makes no sense. Those curves are nowhere near what Fletcher Munson defined.

Just received my MP-50 to replace my aging McIntosh 151. This will go in a dedicated room with 7.4.6 arrangement. All speakers are Martin Logan inwalls that can go down to 40 Hz. 3 Subs are REL S3 with speakon connection and 3 are Rythmic Audio 12 Servo. All subs can go down to 15-20 Hz.
Need advise on how to setup the 4 corner Subs that will be connected to Aux on MP-50. I am confused on how to set the cross over between the speakers and 4 Aux Subs. I plan on connecting the 2 Subs to LFE with a Y. One of the LFE sub is 5' above the ground.
How does MP-50 distribute responsibility of the 4 Aux Subs. I assume Front left sub to front left Sub, front right speaker to front right sub, however, not sure on what is done with the back Subs. Which speakers are assigned to the Subs on AUX.
Any advise setup will be greatly appreciated. Thanks.

You need to read the manual. It's detailed very clearly starting on page 13.

How does the MP-50 handle 2 channel audio when the sub is attached to LFE? Is there a 2.1 mode? Is it better to attach a single sub to 2 aux outputs and send a left and right signal? What is the best way to use a single sub for music and movies? Thanks.

Need Some Help Please.

I've only had the MP-50 installed in my updated home cinema/music system for a few days. Have been ironing out the wrinkles.

Last night, for the first time, we watched a movie to test Dolby Atmos. The movie was Star Wars The Last Jedi 4K UHD with Dolby Atmos.

Repeatedly throughout the movie this message flashed across the screen "Unsupported Audio Signal. Please check connection.".

I'm using Fusion4k High Speed 4K Professional Series HDMI cables to connect my Oppo 203 to my MP50. The cables were secure.

On the MP50, under Audio Processing, all settings are set to "Off" except TrueHD dynamic range control - which is set to "Auto".

I was receiving sound through all my speakers including my 2 Atmos height speakers. The MP50 "Dolby Atmos" and "TrueHD" were illuminated in red.

Repeatedly receiving this message across the TV while trying to enjoy the movie completely tainted the experience.

Can anyone help with this?

A single sub should always be connected to LFE. It will play redirected bass + the LFE channel.

You can try turning off dynamic range control, but this is probably not the issue. You should probably contact Lyngdorf support.

Thanks.

I just turned off TrueHD Dynamic Range Control - but I agree, I don't think that is it.

With respect to Lyngdorf, I only have one support contact and that is Flemming Smith. And I think email is the only way to correspond with Lyngdorf from the USA??

Having said that, I'm hoping someone else has bumped into this issue and has a resolution.

Does the MP-50 use selectable modes or does automatically switch between audio formats? How would it play a stereo signal, LR & sub?

You can manually select the mode on the fly, or you can set a default for each input you create. If you don't select an upmixer, it will play a stereo signal as intended including a sub if the L/R speakers have a crossover.

Hi Duckymomo,

Thanks for the various replies.

When you mentioned the L/R having a crossover, I assume you’re talking about the speaker configuration. Thus, if I configure the L/R speakers to Large (Cutoff frequency 40Hz) on the L/R output and a single sub on the LFE output, a digital stereo signal would create an analog stereo signal to L/R outputs (40Hz and above), and create a down mixed mono analog signal to the LFE output (40Hz and below)?

Again, I really appreciate your help.

Yes. The LFE output plays the LFE channel if present + redirected bass from the speakers.

Set-Up question : do I need to match the gain level on all speakers before running the RP or does RP sets it automatically.

If I have 2 subwoofers both placed in the front. The LCR are all set to large (40HZ) and all the other speakers are 80HZ. Should I set up the system with L and R subwoofers or use a splitter and set them as LFE?

Now I have +/-5dB from 10Hz - 200Hz :-) Before I had a 10dB drop already at 20Hz. Gone.

No need to redo the calibration as the MP-50 only stores the measurements only and does the corrections "on the fly" based on that.

This is according to Lyngdorf support and I can confirm this is the case.



Just upgrade to 3.0.9 and finally you can experience proper (still tight but now linear) LF in your subs. At least the difference is huge in my system...



There is also a "loudness control" that I haven't seen before (??).



I will experiment and measure a bit more and post complete graphs by the end of the weekend.



Thank you Lyngdorf, best company around :-)



cheers,

Erik


Good to see regular updates from them. I'm updating now.
Just curious, should we re do the calibration if bass response changed? (For the "perfect" sake)
