 Question:  Do you know what's the difference between DSP Amplifier and FP Amplifier?
Some users prefer to make amplifier with DSP function in one same machine. Don't need to spare more time to install the extra audio processor. 2 in 1 design make audio system more lighter, simpler to operate. So we create the DSP series based on FP series amplifier.
►4 Channel Class TD Switching power amplifier
►Create SUPER sound quality
►Control the sound effect by Touch on front
4.3-inch LED display screen
►Or control the sound effect by Computer
►Simple DSP software, no need to install, easy to operate it
►Bridge-mode operation for Touring Applications
►Comprehensive protection scheme 
►Use Original Siemens high quality capacitor 14pcs 3600uf 200V +4pcs 2200uf 200V
►Use Original ONSEMI type PNP power output transistor MJ15024G/MJ15025G
►Neutrik XLR*/Speakon connectors
►High Cooling System, 4 Internal Cooling Fans with 8 Rear Small Fans
