DTA series is a series of power amplifiers newly developed by DEKEN for commercial background music applications. Specifically optimized for commercial applications, the entire series uses fanless, silent and efficient digital power amplifiers without any mechanical noise, suitable for all kinds of application scenarios that have demand for environmental noise. At the same time, equipped with the newly developed DSP processing system, it can ensure a complete and equalized music effect at any volume level. This series of power amplifiers are optimized and equalized for DEKEN FIT series commercial speakers, and used together can enhance the audio experience. The series power amplifier has low impedance (fixed impedance: 4Ω, 8Ω) and high impedance (constant voltage 100V, 70V) optional outputs, with a portable and flexible function design, suitable for all types of retail stores, restaurants, bars, conference centers, schools, supermarkets, exhibition halls, shopping malls, hotels and other occasions that pursue sound quality.
