Description

The SMPS power circuit of DA series power amplifiers specially designed for audio applications adopts APFC and soft start switching technology. It can not only powered by 90-285V global voltage but also automatically adapt to the voltage fluctuation and harmonic interference of the power grid to be providing continuous, stable and clean power output. DA has adaptive variable oscillation modulation technology to overcome the shortcomings of traditional Class D power amplifier output that is easy to resonate. The sound quality has an essential leap in DA series high-power output, effectively reducing distortion and improving dynamics while retaining more music details and making the sound quality be clear, delicate and powerful. The new DA series digital power amplifier can perform feedback control on the multiple sampling of the front and rear stages of the power amplifier output filter coil and the current signal, which greatly enhances the control ability of the power amplifier to the load, and can adapt to various complex load environments, whether the load is impedance or capacitive reactance. , Inductive reactance or the superposition of several characteristic impedances.

The application of variable oscillating modulation technology and multiple feedback control greatly improves the low-resistance load performance of the power amplifier. The whole series supports 2 ohm load and works stably, which is suitable for large-scale sound reinforcement systems.

The new DA series power amplifiers provide complete protections against overload, over temperature, short circuit, DC, power supply under-voltage, etc., and are equipped with LED working status indications.
