Feature:
The working principle of the active speaker amplifier board can be summarized as the following steps: audio signal input, control and amplification, sound generation, and sound output. The audio signal is transmitted from the external audio source device to the control circuit of the speaker through the input interface. The control circuit adjusts and processes the audio signal, such as volume control, equalization adjustment, etc. The signal is then amplified by a power amplifier, which increases the current and power of the signal to drive the speaker unit. The amplified signal is transmitted to the speaker unit through current, and the speaker unit produces corresponding sound according to the frequency and amplitude of the signal.
1) Built-in 48K high-performance DSP processor with FIR function, RS485 networking or daisy-chaining for adjustment.
2) Power Supply: PFC Type 50-60Hz AC 90~265V.
3) Professional-grade audio CLASS D amplifier circuit.
4) Fully sealed with its own shielding box, speakers can be installed without the need for a partition.
5) Widely used in line array speakers, full-range and subwoofer combination sets. Such as Dual 8inch, 10inch, 12inch line array or full-range speaker, or 15inch, 18inch subwoofer.
6) Built-in DSP Module, controlled by Computer for Equalizer, Delay, Volume and so on.
