Can MRM play 24/192kHz?

[Wiimer]

The Pro and Mini have a 16/44.1 MRM, do the two Pros output 24/192 with MRM?
(on Amazon Music)

I remember reading somewhere that MRM on the Pro is 24/192 compatible, but I'm not sure.

I plan to buy on Prime Day.

AFAIK there is no hi-res multiroom support for Linkplay implementation. It's on todo list.

 

[Wiimer]

It's a shame.
Thank you!

You may have read here to the contrary - search for @Brantome and “Echo Studio” and you’ll see my findings on that. From the various tests I’ve done, I’m beginning to suspect that Alexa MRM itself is constrained to 24/48 and that it’s not necessarily a Linkplay constraint. I’d love WiiM to prove me wrong though…

Yes, it may be.

Does it mean that Pro to Pro MRM can output 24/48?
(Maybe I still don't understand)

Now, I'm confused because I can buy the Pro for $100 on Amazon in Japan.

Thank you!

I set up my Wiim Pro and the WiiM Pro Plus I have on test in an Alexa MRM group and when I cast to that group from the Amazon Music app, my amp to which the Pro was connected over coax showed 24/48. That was the same result I got when I grouped my Pro and Echo Studio.

Given the Pro and Pro Plus both support 24/192 and I set up an Alexa MRM, not Linkplay, group , that’s what leads me to believe that the 24/48 is an Alexa constraint, not Linkplay.

I’ll only be able to disprove that when Linkplay release hi res multiroom.

However, as has been said before, multi room listening tends to be more casual so 24/48 may well be more than sufficient - would we actually hear a difference between that and 24/192 multiroom?

 

[Brantome]

...and with this small yelling cubes or cylinders?
Sorry, I would recommend to stay completely in the Alexa Echo world for such a scenario.

In terms of their MRM implementation, Wiim devices are in the Alexa world and can participate in multi room groups with real echo devices of which I have several. I don’t need anything larger or better than them in my small kitchen, bedroom etc - the length of time I would listen to music/speakers in those locations doesn’t justify anything better for me.

You are very nice.
I'm sorry, but my English skills are poor and I still can't understand it.

What I want to know is the maximum resolution of "Linkplay MRM", not "alexa MRM". If Pro and Pro+ are linked on WHA, can I output 24/48?

I want to do the following experiments with Linkplay MRM.

WiiM Pro(1) > DAC > Amp > Speaker
WiiM Pro(2) > SUB Woofer

If the resolution is 16/44.1 on Pro to Pro MRM, the "Pro(2)" can be replaced by Mini. So I will buy another Mini.

I can't hear the difference between HD and UHD, but it doesn't matter for me.

Thank you

Let me try that later for you.

Using a mini in an Alexa MRM is constrained to lossy Amazon Music, not even lossless CD quality. I haven’t tried Amazon Music with a Linkplay group yet (or for a while, but I’d have forgotten the results anyway…).

I haven’t tried a Linkplay multi room with a mini and a Pro either , but will give that a try too.

I’ll get back with some results as soon as I can clear some time to test.

 

[Brantome]

On a separate but related note, I understand that the WiiM engineers are looking into the feasibility of using a Pro’s digital out and analogue out at the same time so that the analogue output might be used to drive a sub. It might be worthwhile raising a ticket to ask them if they have made any progress in their investigation of that.

 

[onlyoneme]

It's 48/16 in Linkplay multiroom group when the Mini and the Pro are linked together. I guess that the host downsamples the content and shares it for its slaves.

 

[Wiimer]

Thank you.

The Pro and Mini's MRM shows HD (16/44.1) in WHA.

Ex: A 24/96 track is playing back on Linkplay MRM (Pro+Mini)

I get 16/44.1 HD playing this 24/192 Amazon Music UHD track when I play to a group comprising the WiiM Mini, Pro and Pro Plus. I’m surprised as I have the HD/UHD Alexa setting on for all three devices and I’m sure we’ve been advised to turn that switch off for the Mini in multiroom - indeed I recall Amazon Music multi room not working at all (just silence) when I first tried the Mini and Pro with that option turned on for both.

When I drop the Mini from the group, and leave just the Pro and Pro Plus, I get exactly the same - HD 16/44.1

That's an interesting.
However, if the analog output is used as the SW output, an implementation of a high-pass filter is ideal.

My bookshelf speaker needs SW and now I'm outputting from WiiM to AVR (Yamaha's AVR have a PEQ).

I think the advantage of two WiiMs use for SW out is that can set the EQ separately for each WiiM. This allows to add a pseudo-high-pass filter to my bookshelf.

Thank you for taking the time for me.

It's a bit disappointing that "Pro and Pro" would get the same result as "Mini and Pro", but I could understand.

Thank you all

 

[Brantome]

That’s a good point - if the WiiM engineers do do that, they may also need to allow separate EQ settings for each output.

 

[Wiimer]

Yes, it's exciting to imagine those features coming to life in future updates (or new products).

Until then, I'm going to enjoy it while taking advantage of the features that WiiM has now.

You've used Amazon Music content, I've tested a local network content over UPnP, 96/24 track. The behavior can vary as for the local track there is no way to ask a service for lower resolution version. It must be downsampled locally.

I have a similar need for subwoofer output to supplement bookshelf speakers, but my bookshelves are digital so I need both digital AND analog outputs active. Hopefully this will be addressed in either firmware or hardware improvements. However, your idea is a very interesting solution that I had not thought of! I’m wondering if you ever tried it?

Hi,
I just tried it today. Because a new amplifier has arrived. To conclude first, it generally worked.
 However, there are some minor problems. The first problem is that the output to SW is too large. I set the analog output of the Wiim Mini to 500mV, but I can still hear the sound when the SW volume is set to zero (this problem can be solved by installing a preamplifier or DAC between the WiiM and SW).

Another problem is that sometimes Wii M becomes unable to maintain MRM. There is still a lack of verification for this, so we will continue experimenting.

This is my devices and wiring diagram.

--[1]----------------------
WiiM Mini
(AUX) > (2*RCA) > SW [Polk MXT10]

WiiM Pro
(Opt) > DAC [Topping D30 pro] > (XLR) > AMP [TP RA3] > Bookshelf [Focal chora 806]

The WiiM Pro's EQ is set to -12db instead of 31Hz and 63Hz.
----------------------

As mentioned above, some problems were found, so we have now returned to the following configuration.

--[2]----------------------

WiiM Pro
Output 1 (Opt) >
DAC [Topping D30 pro]
XLR OUT > AMP [TP RA3] > Bookshelf [Focal chora 806]
RCA OUT > SW [Polk MXT10]

Output 2 (Coax) > AVR > (PREOUT/RCA) > AMP [TP RA3] > Bookshelf [Focal chora 806]

The WiiM Pro's EQ is set to -12db instead of 31Hz and 63Hz (And make the volume of SW a little louder).
----------------------

I feel that pattern1 is easier to balance than pattern 2 and the bass texture is better. I liked that you can control the volume of SW with the WiiM app.
