DK series multi-channel digital power amplifier is a brand-new breakthrough of VAKAPRO in the field of power amplifier development.
The DK series power amplifier integrates the latest PFC technology, and self-calibrates timely within the global wide voltage range of 50-350V. Its high efficiency and excellent stability make it easy to cope even in an environment with unstable voltage.  High efficiency and stability are derived from the advanced class D amplifier circuit and SMPS patch power module designed in Europe.  The ultra-high power density and optimized intelligent circuit enable the amplifier to obtain a super output in a small 1U space.

Application: It is widely used in large-scale stadiums, stadiums, theaters, performing arts halls, concert halls, churches, auditoriums, outdoor mobile performances, high-end bars, high-end KTVs, nightclubs, entertainment halls and other advanced sound reinforcement venues that require high-quality sound.
