We could not find any corresponding parameters, please add them to the properties table
1. High-quality digital audio transmission using network audio module, controlled network audio server plays programs
2.2 line (AUX1, 2) input, each channel can independently adjust the volume, 1 line output, can be connected to pure post-stage amplifier to expand power,
3. The output power is 500W, and the output frequency response range is 100 ~ 16KHz.
4.3 microphone input (MIC1, 2, 3): the first microphone (MIC1) has the highest priority, and has strong cut-in priority function,
5. It has the function of second-level priority forcible cut-in, with independent adjustment of treble (TREBLE) and bass (BASS).
6. Using FET pre-amplification, traditional transformer triode push-pull circuit, sound beautiful and pure, built-in 2-level active high-pass filter and low-pass filter, automatic wave reduction and signal reduction
7. Machine abnormal working protection warning function: when the input signal is too large, the load is too heavy, or the line is short-circuited, the corresponding indicator flashes.
8.Temperature protection: High-current high-speed fan. When the temperature of the machine rises, the temperature protection circuit will start the fan, and the speed of the fan will automatically increase as the temperature rises.
