Power Amplifier – Series Public Broadcasting

6 MIC inputs, one has a priority function
3 LINE input
2-band EQ
Digital effect processor
Built-in MP3 has USB, FM, Bluetooth
There are 8 ~ 160, 70V, 100V three output modes, and 1 LINE output
This series amplifier output power are 240W – 600W
Compare with the analog amplifier, the same level Class- D amplifier can be more portable, which loses 60% weight, and reduces energy consumption for 40% at the same time. And this series has over-temperature protection, over-voltage protection, over-current protection, short circuit protection, input signal limit, output current over current limit, and other perfect protection

Rated output power: 500W
Output: 3 output modes: *4~16Ω or 8~16Ω, *70V and *100V
