The DS 1.2 is a state-of-the-art Class D amplifier module for active subwoofer use. Accurate
rendition of the low bass range is a substantial component of a high-quality music
reproduction. For an impressive bass rendition large loudspeakers are unfortunately inevitable.
If you prefer small loudspeakers for optical reasons, you can use the DS1.2 to extend your bass
rendition. The crossover frequency is adjustable steplessly between 50Hz and 150Hz. Due to
this large range of control a problem-free connection is possible to different subwoofer and
other loudspeaker systems. Additionally this active system has a low bass rise. An active 4th
order subsonic filter with Butterworth characteristic protects the loudspeaker against
mechanical overloading, since the ultralow portion of the fed signal would cause extreme
diaphragm deflections.
Connections
Be sure to disconnect the DS1.2 from the mains before proceeding!
Connect the loudspeaker, wired with wire of sufficient cross-section (1.5mm2 or 15AWG), to the
amplifier board as shown in the picture above. Use suitable crimp connectors and crimp them
with a suitable crimp tool. Check the voltage selector on the front panel and make sure the
voltage is set according the mains voltage used in your country.
