1. Standard 2U chassis, aluminum alloy panel, pull-out design, convenient and beautiful

2. Four independent signal processing and power output channels, non-interference and independent control, each channel can independently adjust the volume

3. 4-way TRS sound source socket input

4. Humanized indication functions, including signal indication, protection indication, distortion indication, startup indication, power indication, and other functions.

5. Machine abnormal operation protection warning function: When the input signal is too large, the load is too heavy, or the circuit is short circuited, the corresponding indicator light flashes to indicate, which has extremely high reliability.

6. Perfect temperature protection: High current and high-speed fan, low working noise, and good heat dissipation effect; When the machine temperature rises, the temperature protection circuit will start the fan; The speed of the fan automatically increases with the increase of temperature.

7. Two power output methods: constant voltage output 100V, 70V; Fixed resistance output 4-16 Ω
