SX-M2D2 Product Announcement

The SX-M2D2 is a lightweight 2 channels high resolution dual-domain microphones preamplifier with integrated USB audio Class 2. Compact, low power, battery powered, the SX-M2D2 embeds similar high performance dual A/D converters than the SX-R4+. This product is the ideal companion for various mobile environments. Its ergonomic has been carefully designed for convenience and easy of operation.

Inputs / Outputs

  • 2x mic/line inputs on TA3, electronically balanced, with phase reversal, 48V phantom, LF cut and level control on the front panel
  • 1x AES3/AES42 on TA3, transformer balanced input with phase reversal, 48V phantom, LF cut and level control on the front panel
  • 1x line output on TA3, 2 channels analog unbalanced
  • 1x AES3 output on TA3, 2 channels transformer balanced with ASRC (48/96/192k)
  • 1x USB audio 2 channels input/output on micro USB type B connector
  • independent line/headphones stereo output on mini-jack

Performance

  • 135 dB (A-weighted) overall dynamic range
  • THD < 0.001%
  • 90 kHz overall frequency response @192kHz
  • 24-bit 48/96/192kHz

Powering

  • external DC 9-18V on Hirose 4-pin
  • external DC 5V on micro USB
  • removable lithium-ion battery, charged with external DC input
  • intelligent energy management

User interface

  • 128×64 monochrome OLED display
  • two rotary encoder for gain control
  • intuitive menu navigation

Mechanical

  • Machined aluminum housing
  • overall dimension: 74 x 28 x 130 mm (2.9’’ x 1.1’’ x 5.1’’)
  • weight 300g (0.44lbs) with battery
  • mounting holes on both sides
  • optional mounting bracket for still camera

Note: preliminary specifications, subject to change without notice

Woohoo this looks awesome!

 

The only thing I'm not a huge fan of is not having any balanced analog outputs. Any chance of making that analog output a TA5 so that we can get balanced signals?

 

AES is nice to have but for me I will use analog much more often. 

 

Love the mini-jack output as well - that will be perfect to get two extra channels on my MixPre-6. Specs say headphone/line out. Will you be able to switch it between the two modes? I'd rather not have whatever headphone amplifier is there in the signal path when using this as a line output. 

 

Looking forward to it!

As someone seriously hoping this appears (and very happy that Sonosax offers preliminaries for feedback) here is my immediate feedback.

 

As a field recordist often out in the 'middle of nowhere' and WEEKS or more away from simple replacement parts - I am a huge fan of simplicity and conformity for common/essential tasks. This and several other reasons would make me want standard XLRs for the two inputs. Extra cables are bad enough - losing the extra cable is (all too often) a disastrous nightmare.

 

Would be more than happy to make up space by having the AES3/42 on XLR1 if so : no great reason for an extra connection for a 2 channel unit? Expect others might have good reason to disagree but have to say I don't know what it may be.

 

Not so bothered on not having balanced analogue outputs but might expand its user base (could increase other uses - I am well aware that this is designed as an input accessory for the SXR4), nor output connector.

 

Looks good. And good to think that a series of small '+2' modules might expand the R4+

 

Still think there is perhaps a strong potential market for a (same footprint/body as the AD8) AD4+4, being 8 AD converters but with just four of them having preamps in front of them. A compromise between cost and those who might need the converters just at line level (which I've seen at least once here).

Jez, no more likely to find a working XLR in the 'middle of nowhere' than a TA3. Probably find a cola can (empty), AA batteries (flat), AK47 bullet (casings), USB cable (broken) and maybe some goats:

The good thing about TA3/5 is they are almost as easy to solder as XLRs but considerably lighter and so easier to carry spares. XLRs would also have meant connectors on the 1 side of the unit (like the DNS2) which makes it harder to fit in a compact bag, imho.

At least it's got T power tho... oh.

Any hints at price?

Not cheap (expect around nzd$1500 but that's pure speculation.. ) , as a biased rx4+ owner it'll sound awesome and make your boom mics sound simply fantastic. I'm very impressed with the quality of my mkh50/dpa4017 through the rx4+ preamps so far, what's more I'm often asked by long term clients "what did I do?"...

As most of us are running cables 6inches or so into a mixer/recorder, unbalanced analogue isn't really an issue.

But that's the theory..

Me, I'll be using AES.

I would also like to see balanced outs, mainly because it would increase the potential market for Sonosax in a big way i.e. computer AD/DA for music. I would mainly be using AES out in the bag or on the cart with SXR4+ and the analogue for iem/possible mic pre for wireless boom or simple straight to camera jobs. It would be nice if the faders could be used as controllers in the SXR4+ but no biggie. Apart from that it looks great size/function and i know the mic amps are very very awesome already.
