Audiolink protocol
POE column adopts 3-inch full frequency unit
Built-in POE amplifier
Built-in DSP processing
One network cable realizes audio, power supply, DSP configuration and real-time signal control
The SPK series full-frequency linear POE sound column adopts a 3-inch full-frequency unit, a wooden speaker, and a built-in POE amplifier, which has a high degree of sound reduction and DSP processing. The speaker only needs to connect a network cable to realize audio, power supply, DSP configuration and real-time signal control.
●Built-in DSP processing, support gain, mute, equalization, pressure limit, noise gate software adjustment
●AUDIOLINK digital transmission protocol, ultra-low latency, wireless loss and interference
●A network cable transmits audio signals, control signals, and POE power
●Overcurrent protection, high temperature protection, overload protection
