SX-DD2 User manual 3/19
1 Introduction
Congratulations! By choosing the SX-DD2, you have acquired a very high quality
Preamplifier / Converter, the result of the hard work of a renowned engineers team.
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 first preamplifier/converter of the range you are proudly installing concentrates all
the know-how of the brand in an ultra powerful device. It is at the same time:
•A very high quality preamplifier
•An analog-to-digital and digital-to-analog converter
•A headphone amplifier
•A control system for the different sources
A built-in matrix allows any input to be routed to any analog or digital output(s). The
controls are fully digital, allowing access to all menu features with just two rotary
encoders. A high-brightness graphic display shows the available options and settings.
An infrared cell allows the control of the preamplifier with a remote control.
Note that, unlike many devices of this kind, the signal remains completely analog
when used in analog input/output mode.
As with all SONOSAX products, the SX-DD2 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.
