1 Introduction
Congratulations! In choosing the SX-M2D2, you have just purchased a very high
quality audio device, the result of the hard work of a team of renowned engineers. For
more than forty years, Sonosax recorders and mixers have been recognized by
professionals around the world for their outstanding technical features and unmatched
musicality.
The tool which you hold in your hands is the latest addition to the range, concentrating
all the brand's know-how into an ultra miniaturized case. It is:
•A very high quality stereo preamplifier
•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 integrated 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 unavailable.
As with all SONOSAX products, the SX-M2D2 is built without any compromise in
quality, using only the best components available and passes stringent quality
controls.
The information and instructions contained in this manual are necessary to ensure
safe operation of your equipment and to maintain it in good working condition; please
read it carefully.

3 Powerin
3.1 Intelli ent Power Mana ement
The SX-M2D2's intelligent power management is a combination of hardware and
software which optimizes the distribution and use of electrical power.
It includes the following:
•High efficiency current limited switching power supplies with automatic load
prioritization
•Automatic battery charger, low-voltage battery pre-conditioning, detection of
faulty cells and thermal monitoring for charging pause in case of overheating
•Ultra low standby current
•Removable battery charge state and voltage measurement
•Under-voltage automatic power-down
•Smart load shedding, which shuts down unused inputs and outputs
•Display auto-off
3.2 Power Sources
The SX-M2D2 has two external power connectors and an integrated battery.
The battery must be present in the device to ensure that all functions are always
available.
These sources are independent and can be used simultaneously to prevent a power
failure.
When a power source is disconnected (or fails), the SX-M2D2 automatically switches
to an available power source.
This list reflects the SX-M2D2 power sourcing priority:
1. Hirose 4-pin connector
2. USB Power connector
3. Removable Li-ion battery cell
NOTE
USB Power input can drain up to 1.3A
WARNING
The battery must be present in the device to ensure that all functions are
always available.
The SX-M2D2 can be powered by an external source, without a battery
for a few moments when replacing a discharged battery with a charged
one.
