An analog-to-digital and digital-to-analog converter
A headphone and monitoring amplifier
A USB sound card compatible with any type of computer or smartphone
An audio mixer with an integrated full featured compressor-limiter.
An embedded digital matrix allows any input to be routed to any output or to an internal stereo mixer. The fully digital controls allow menu access to all features with only two rotary encoders. A high-brightness graphic display shows the available options and settings as well as four modulometers assignable in pairs to any signal source. The power supply from a standard battery, recharged in the device, guarantees hours of autonomy, even if the two power sources available to the SX-M2D2 are unplugged.
The possibilities of implementation are endless:
As a complement to a TV cinema recording equipment or as a small stand-alone mixer.
As an AD converter preamplifier for a boom operator, with the possibility of mixing talkback with local monitoring
For a radio journalist who will be able to record and monitor 2 mics interviews on his smartphone.
For the musician or podcast creator who wants to benefit from very high quality inputs and outputs on his computer (PC or Apple-Mac) or smartphone (iOs or Android).
For the audiophile who will benefit from a DA converter coupled with an exceptional headphone amplifier.

Most recent Apple iPhone, iPad and Android devices work with the SX-M2D2. This is a list of suggested apps. Please note that since these apps come from third party vendors, no support is provided for them.
Apple OSX version 10.6.4 and above, Windows 10 version 1703 and above and all (modern) Linux distributions natively supports USB Audio Class 2.0, no driver install is required.
Sonosax provides two types of 3D print for your SX-M2D2.
Slide your SX-M2D2 into this box, protective case, mounting accessory, whatever you like to call it. Hot shoe fixing slides allow you to attach it to a camera. You may also slide it into your sound bag. The connectors are protected and the cables come out elegantly on the side.
Feel free to modify the original file according to your needs and ideas. And if you do, send us your photos, the most beautiful ones will be published on the sonosax.ch website.

In each .zip file, you’ll find:
a Solidworks 2015 or later 3D file (.SLDPRT)
a .STL 3D printer file
Note: Sonosax does not provide this accessory in physical form. Only files for 3D printing are available.
