Neumann KM-D Digital Microphones

[John Willett]

I agree and it's on my list - after the MKH 8020 stereo set, the MKH 8040 stereo set, the Nagra VI, the U87 Anniversary Edition and a new PC.

and a new PC.

Stop using them then, and use a proper recording system

I *do* use a proper recording system.

You don't think I actually use a PC for recording do you? It's far too risky - I don't trust them that far.

But I *do* use a PC for editing and mastering. If it all goes tits up I still have all the original material.

Using a PC for recording - madness - whatever next.

[Aural Reject]

Trust no-one

Editing? You mean they don't get it right first time like my lot?

I use a PC for recording -- with the SADiE LRX2 -- but for critical stuff (what isn't?) I back up with a Genex 8500 Hard disk recorder. But to be fair, I've not had any problems so far recording to the laptop with an external drive....

As I promised - I *have* now bought the KK131 flat-omni heads for the KM-D.

I have yet to use them in anger, but will probably use them more than the 183 once the current recording project is finished.

Update:-

Neumann have released, in the last week, updated RCS software (v2.0.1) that complies with the latest version of the AES42 standard.

They have also released new software updates for the DMI-2 controller and the KM-D series, D-01 and TLM 103-D microphones.

I have just updated all my kit.

The new software also works with the new Sennheiser MZD 8000 digital module that is due for release very soon.

Update -

Neumann have recently launched more new capsules for the KM-D series including the KK 133 omni with ball head and KK 120 fig-8.

They have also launched the new KM-A analogue version of the KM-D so the same capsules can be used AES42 digital or conventional analogue.

The Neumann KM 185 D has come out and it's not bad. It has a good A/D converter. I used it to record a pianist at a piano teaching academy

[DaisyMarie]

Why not? We are using them in for our guitar lessons london

The KM 185-D was one of the original 3 launched in 2006.

[John Willett]

Neumann have just launched the DMI-2Portable - it's a slimline DC powered version of the mains DMI-2.

Shipping starts next week (week 3, 2011) and I have already ordered a pair of them so I can record four AES42 digital mics at the same time into my Nagra VI.

For some reason it's not on the Neumann website yet; but I'll post the link when it's up.

That post, and the other one above yours are both spam.

The new DMI-2 Portable interface is out now and I received a couple the other day to go with my Nagra VI.

It's not on any website yet, so this is a scan of the Owners Manual pictures:-



I will upload pictures of my own units as soon as I ave them all sorted and cabled up to the Nagra VI.

The DMI-2 Portable is DC powered and I can power two of them from my Nagra VI to record up to four digital mics at once.

[John Willett]

Not sure why the image of the DMI-2Portable does not show in the above post.

The picture is HERE.

OK - here it is.

My Nagra VI and the two DMI-2Portable interfaces for recording four digital mics. at once:



The two DMI-2Portable are both powered from the Nagra VI and they are clocked from the very accurate word clock in the Nagra VI.

[John Willett]

The DMI-2Portable is now on the Neumann website HERE.

For more information on digital microphones...

I have written two AES papers on the subject.

The first was presented at the 130th AES convention in London in May 2011 and the second (a bit longer) at the UK AES Conference "The Ins and Outs of Audio" in June 2011.

Both these papers list all the products for AES42 digital microphones from all manufacturers to give a complete picture.

You can download the PDFs from the links below:-

Digital Microphones - What's it all about?

Digital Microphones - AES42 and all that

I trust these will be useful in explaining AES42 digital microphones.

Forgive me if I missed something. I read this thread. I read the SOS review. I wasn't able to find any audio samples anywhere.
I'm excited about the possibilities that digital mics present.
I would love to hear a shootout between perhaps these Neumann models and their analogue counterparts maybe?
Maybe someone could pit them against an industry standard, well known combo stereo small diaphragm pair/GML or Millenia pre.
If anybody knows of where I can hear high quality audio examples I would love to entertain the idea of saving for these.
Thanks.

Forget "audio samples", they tell you very little - especially if they have been mangled into MP3 files.

What you get with AES42 digital microphones is the sound of the microphone without any of the colouration that analogue pre-amplifiers add.

You also get a better signal/noise ratio because the sound is digitised in the microphone and you do not have to back-off in the mic. pre. nor ADC to allow headroom for peaks.

Also - the signal is not affected by any stray RF pick-up like analogue signals, so you get a cleaner sound.

Each little thing in the analogue chain adds a bit of noise and distortion, mostly very low and is hardly noticed. But the lack of this on a digital mic. *is* noticeable.

I'll see if I can get a CD quality (16/44.1 uncompressed) sample hosted somewhere that I can link to (now I have a Copy account with free storage) I will try and put something up.

In the meantime, send me a PM with a snail-mail address and I'll send you a CD.
