Features

• Stable, precise and pure quality defines the DCA1812,which is distinctive in quality design and stability.

• Stable and dependable performance

• Precise and pure quality.

• Designed for the applications of conference systems

• Always in pursuit of the best
  Due to a broad span of working voltages (range of 80-130V or 170-270V), strong/versital voltage is always present. And, an advanced SMT strengthens stability even more. During this unit’s pre-release R&D, several test-experiments were done to ensure that the DCA1812 could perform with precise clarity, ultra-low distortion and super signal-to-noise ratio. Thanks to the unique and flexible power system, DCA181 (with a huge capacity storage), this compact 2U design makes set-up and transport a breeze. And in the event of a repair, modular replacement is fast and simple. The perfect protection circuit system makes this unit as die-hard as a miliary-craft! Before the DCA1812 production-release, it underwent years of testing to guarantee it to be a sophisticated design (both interior and exterior).
