Features

● All adopt SMT production technology, use H-class circuit technology, have sophisticated circuit layout and high-efficiency power conversion.

● The ultra-high power imported iron core toroidal transformer is matched with 10000UF ultra-large capacity capacitor, which can release a strong low frequency.

● The optimized radiator structure and high-quality cooling fan are adopted. The fan automatically accelerates with the internal temperature change, ensuring that the amplifier can operate reliably under high power conditions for a long time.

● When the matched load impedance is too low or the temperature is too high, the machine will adjust the power supply to reduce the internal resistance of the power supply, which can effectively protect the machine while improving the sound quality, greatly improving the stability and reliability.

● The amplifier has high conversion efficiency, low distortion, and can present beautiful sound. The entire series adopts a 2U chassis structure design, which is lighter and more space-saving than traditional amplifiers, and has a simple and unified appearance.

Q: What are the core technical advantages of Amp For PA Speakers? How to ensure high-fidelity output?

A: The core advantage of the professional pure power amplifier (2×200W) lies in its pure amplification capability without sound coloration and high-efficiency design:

Fully balanced amplifier circuit: adopts differential input stage and symmetrical power output stage to suppress common mode noise, signal-to-noise ratio ≥110dB, and ensures the restoration of weak signal details.

Class-H topology: Dynamic switching of power supply voltage (such as ±40V to ±80V), efficiency of more than 75% (traditional AB class is only 50%), and the temperature is 30% lower than that of the same power AB class amplifier when running at full power, which is suitable for long-term high-load work.

Multiple protection mechanisms: including DC output protection, overload limiting, short-circuit protection and intelligent temperature control fan, with aluminum heat sink and air duct optimization design to ensure stability.

Ultra-low distortion index: THD+N (total harmonic distortion + noise) ≤0.005% (1kHz, 4Ω), frequency response range 20Hz-20kHz (±0.1dB), meeting the high-fidelity needs of recording monitoring, theater sound reinforcement, etc.
