The Official Mcintosh Labs MX-151 & MX150 Owner's Thread - Page 11

post #301 of 479
How much is the upgrade cost from MX150 to MX151 (free with just SW upgrade?)? I am intrigued by Mcintosh - I heard them at Magnolia and room perfection/correction provided a audible impact. It uses BurrBrown 1792 DAC (at least for front end I know of)- while DAC chip implementation is more important, I am not surprised.

I need to figure out how to buy this beast by Christmas!

Anyone have problems with their MX150/MX151 locking on to PCM multi channel (5.1/7.1) signal and the processor would only output stereo 2.1?

I've had this issue for some time with the PS3 on games output in PCM. For example in NHL 2K11 the initially lock into 2.1 stereo but if I go into the game settings and cycle through the menus my MX150 would eventually lock into the correct MultiCh signal. This happens to other games in the PS3.

Thinking it was only this PS3, I recently acquired a PS4 and the issue still exists in the game Battlefield 4! I'm reading other users with other Japanese receivers are not experiencing this at all.

My warranty is running out shortly was thinking of sending it in. Any Mx150/mx151 have an issue with their unit not locking in on the correct PCM signal?

I will check later - I do have a PS3 but rarely use it, and generally bitstream everything from all my sources.....I would call Chuck Monday - they are beta testing new firmware, so perhaps this issue is part of the fix list (as the TrueHD decode issue is).

I tested the Oppo set to ouput PCM. Worked fine.

Thanks for your insight.

Bitstreaming is a non-issue and my processor can process here correctly. The issue appears to be related to processing PCM signal.

I'm hoping the new firmware would apply to these cases but not sure I want to wait for that and still have an issue with the processor.

If I send it in to Mcintosh, you think regular ground courrier would be safe enough for the MX150 in its double box or should I think about shipping it freght on a pallet?

Though I use a Universal remote and the McIntosh Internet address to control it for my brothers who are used to DirecTV remotes it has been a pain changing the volume on our football Sundays. Until now. The Xbox One has been a cool device/gaming system. Just by saying Xbox volume up, Xbox mute, or Xbox volume down the MX151 has obeyed 100% of the time! Very cool!!!

Can a Mcintosh MSD4 be connected to the MX-151 and work together to provide the AC3 for Laserdiscs? Or is better to use a demulator?

Why try and retain Laserdisc in 2014? Not being a jerk, but it's not worth the complications.

I would think if you must, get a demodulator and use the 151 for your surround decoding as it is much more advanced and current...

Yes i know what you mean but still have quite some discs and very cool editions and quite few players. It's like a hobbie, but something i don't use quite often.
Anyway the MX-151 is only something i am considering, not a go for now. I am checking a few processors before i make a decision.
Also heard MX-151 has some HDMI issues... is that true?

I am considering also RS20i, and ADA, that is the best for Home Cinema.

Hi, I decided to try the voicing app and am having issues.

I am running win8 and the app seems to run fine. I selected some curves saved the file and then with both usb and mac mini(sent through email) tried to upload the file.

I am using the web interface as posted on the main page.

The usb does not appear to get recognized. When selecting storage nothing comes up as it just shows the defaults .

If I select upload I see the mac and can choose the file. I go through choosing the file etc and then when I select update the MX states the file format is not correct. Note I did confirm I have a name.voicings.xml.

Appreciate any insight.
post #311 of 479
Triple check the file extension when saving the sound profile. I had the same issue initially.
post #312 of 479
thx for the response.

FYI, I finally got it to work by switching to another pc windows 7 based. Not sure it is the OS exactly but once I did that it recognized the file using the upload.

I had to install .NET from Microsoft but once I did it all worked.

On the mac uploading the file or using my win8 laptop it would fail during the file upload.

The error was " voicing set file content was not valid"

Just curious...

Has anyone heard if McIntosh is going to release an upgrade to the MX151 this year? I'm in the prelim stages of looking to replace my Anthem D2v.

Tnx.

No word...probably not until CEDIA in the fall at the earliest...

They have a firmware upgrade available now. Call your dealer or McIntosh.

post #316 of 479

I have had an Anthem D2v in the past and recently had Marantz 8801 for a little while, and both of those systems required that your microphone is placed vertical and also in an orderly fashion across the listening area (one in the middle and then few on each side of the central area).

 

I do not see much guidance on microphone placement for my MX150, it sounds like place near walls, floor, ceiling, but nothing specific.

 

So my question is that I should select random locations, and angle of the microphone can be anything, like pointing to the floor, or pointing to the ceiling, etc., just does not sound right.

 

Can some one elaborate on this please for me. Thanks.

The first few posts in this thread have some good notes, docs, and a video to assist

Is there a published list of what the firmware addresses I'm aware of at least 2 issues it's supposed to correct.

When I asked that, this is what I was told:

 

"The main improvement is decoding multichannel LPCM and DD+. "

It fixes the Dolby True HD bug, which caused nasty clipping on certain tracks...

post #323 of 479
I am trying to create my own voicing set to include RWD and JBL from the beginning of this post. I have them loaded in one of the slot, and put a new name for that particular voicing and then I saved the whole set by Save Voicing. When I come back and open that voicing file, that voicing curve shows up in the right slot, but it does not show the name of that voicing, neither does that voicing becomes part of the drop down, you would expect that. Can someone help? Thanks.

Thrang, Paradigm25

 

could you post the firmware file for download. I send a mail to Mcintosh, but no answer yet.

 

Thank you very much

I don't have the release version. It will have to come from McIntosh when they are ready to make public.

I've personally not heard that it had been released.

how is the phono section on the mx-151 or 150 or 121?

its moving magnet type but would work with high output moving coil as well.

"There is a Precision Phono Preamplifier for Moving Magnet Cartridges" is the only info I can find. I am considering pro-ject audio phono rs to use with this ssp.


http://project-audio.com/main.php?prod=phonoboxrs&cat=boxes&lang=en

am I upgrading/downgrading or staying about the same level?


my TT is pro-ject rpm 9.2 with sumiko bluepoint evo cartridge.

http://project-audio.com/main.php?prod=rpm92&cat=turntables&lang=en

also have the speed box s for quartz accuracy for the motor.

http://project-audio.com/main.php?prod=speedboxs&cat=boxes&lang=en

any help is appreciated thanks

I don't own a turntable, so I've not ever delved into the phono section.

I don't think the MX-151 is turntable friendly because it does not have an analog pass through. Everything goes through its D/A converter.

Well, if you like Room Perfect, that's a good thing...smile.gif
post #330 of 479
Its a preference and many don't prefer it. I think a/d d/a can work with analog sources in room perfect case it can even improve too.

I am pretty sure most new records are from digital masters anywat
