The DA Series is a new generation of high fidelity, high power stereo output professional digital amplifiers developed by DEKEN, continuing the design concept of the exquisite and excellent 1U model. The manufacturing process strictly implements international quality system standards and has a perfect management and monitoring system. The device uses PWM audio modulation technology, power factor correction (PFC) and other advanced technologies to improve the performance of the amplifier and reduce the consumption of power supply current, so that the series has a very high efficiency. Provide stable and reliable 2Ω drive capability, suitable for a variety of speaker use requirements. The series provides 2-channel and 4-channel model options, suitable for a variety of large stadiums, mobile performances, entertainment projects, cinemas and various commercial audio system projects.

Features:

  • DEKEN classic 1U ultra-thin chassis design, novel appearance, lightweight design, saving space and transportation costs.

  • Using PWM audio modulation technology, with high efficiency power conversion circuit, effectively recycling useless electric energy, strong power output, low power supply consumption, green and environmental protection.

  • Front panel precise gain control, with power, signal, clip and protection working signal lights.

  • Adopting active PFC and soft switching technology, high power correction factor and strong adaptability.

  • High stability, high fidelity sound quality and sufficient power.

  • Stable and reliable 2Ω drive capability, suitable for a variety of speaker use requirements.

  • The bass is strong and thick, the mid frequency is mellow and sweet, and the high frequency is clear and delicate.

  • The design of heat dissipation and exhaust system from the back to the front ensures the long-term and high-reliability operation and use of the device.

  • The rear DIP switch is used to select stereo or bridged operating modes.

  • Unique fully automatic protection circuit design for each channel, with DC, overheat, overload and limiting protection functions. Standby automatic sleep mode, power saving and durable, effectively ensuring the safety and long-term use of the device.
