Using local area network digital audio transmission technology, the
 signal has no compression, loss, and delay;
 The interface is a 10/100M network audio module, which adopts
 the ARM+DSP architecture, which can receive network audio data
 streams, convert them into audio analog signals and output DC level
 playback sound quality;
 Speaker impedance: 4 ohms;
 Distortion: 2%;
 Frequency range: 55HZ-21KHZ;
 Sensitivity: 91db;
 Type: Full-range speaker;
 Audio power: 125W max;
 No need for a power amplifier link, the use of a network cable link can
 achieve broadcast, music playback, and setting area playback;
