1/4

I found same noise on BOTH 1/4" input channels.  This issue is ONLY with analog inputs, so bit-bucket users have no problems with analog input related noise.

As mentioned in other posts about M-Audio MT1, engineering, production design, and final production quality assurance testing is split among different groups on different continents.  M-Audio is truly an international effort.

It would seem there is lack of engineering follow-through on various stages of product development. So when the product is finally shipped, there is a lack of refinement and quality check process typical of all-done-in-one place engineering/production like typical of a company like Sony who rarely ships out anything with avoidable shortcomings. 

This engineering-to-production process is fractured with M-Audio on MT1 and MT2 so performance/quality as pertains to what is finally shipped is often plagued with shortcomings.  Or so it seems , as we too often get a kinky, untested M-Audio product needing many fixes after we have purchased.

A short 0.5MEG 24bit/88.2K wav clip of the unbalanced 1/4" input noise at -35 dB reference input gain is here for download:

After 5 days with no response to the online request for service (with sent noise graphic) posting on their website, I resorted to calling technical service by phone to discuss my MT2  and what might be done.  So far, they've agreed to 'repair' the excessive noise and low-pass filtering at 88.2K problems I found within a 3-4 week time-frame. 

Stay tuned.

Doesn't sound like a sprinkler, it sounds like a helicopter. Good thing I only use the SPDIF in. I wonder how it will sound running my CA cards>9100 pre> MIC input? Might have to give it a try.

Has anybody checked to see if this thing really gives 48v?

Did anyone get any response on the problem with the 1/4 inputs?

As an early MT 1 owner, watching this thread unfold is a big deja vu......

Heh, I'm with ya on that, prolly a big reason why I opted out of the beta testing this go around

M-Audio's first response was: never heard of the problem; exchange your unit at the retailer.

I did so, got another unit with the same problem.

M-Audio's response to this: use only balanced inputs to the 1/4" jacks.

Which means, the unit is not capable of recording from unbalanced line-level inputs.  The old MicroTrack 24/96 worked fine with unbalanced sources...

We'll see what happens next...

I'm still waiting for mine which I preordered though Sweetwater and they received their initial batch over a month ago now. I wonder if M-Audio is quietly fixing the 1/4 problem.

Until they come up with a fix, I am happy. Just use the SPDIF line. Also, when you are recording in 24bit, how long does 2GB last, and if it is a seamless split, does that mean that it pulls up in one wav. file. Or do you have to merge the two files together?

[anhisr]

2gb will last just short of 1 hour.  After that it starts a new file.  You have to merge the files in post.  In Wavelab it is easy as they have an option to add another file to the end of the file you have open at the time.

If you do 24/44 or 24/48 2GB will last 2 hours. I tend to use 24/44 most of time since I can't tell the difference between 44 and 96 and it saves a step in post.

24/48 will give you 1:55

Thinking about picking one of these up so I can retire my laptop.  I'd use it primarily as a bit-bucket, so it seems I'd avoid most of the issues being discussed, but occasionally I'd use it for stealthing or for perhaps a sbd patch while I record Aud.

How's the A/D compare to a JB3?  What little stealthing I do is currently done with a JB3 at line-in which is not that great, IMO (though certainly better than a JB3 at mic-in), so if this was comparable it'd be worth it to me.  Thanks

Thanks. Anyone use Sony Soundforge 8.0 to merge the two tracks?
