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.
Features:
The whole series of fanless and silent design, no mechanical noise.
2-CH microphone input, microphone input can be compatible with LINE, MIC level input. Mic input has priority, mic priority input can attenuate other input signals (Automatic mute function, attenuation value adjustable).
MIC2 is designed with a combination of XLR and TRS input female socket, providing the +15V phantom power, suitable for a variety of microphone inputs.
Each microphone is equipped with independent treble, medium, bass, and input gain tone control knobs.
2-CH AUX input, line input select stereo or mono audio source input.
1-CH local audio input, support USB or Bluetooth music playback, and with recording acquisition function.
Local playback can customize the output line, and each output is equipped with independent treble and bass control knobs.
Built-in chime and alarm siren sound switch, can support external alarm sound.
Each input is equipped with an independent volume control knob.
