Switching Power 4-Channel PA Amplifier (2*4000W)

Switching power 4-Channel PA Amplifier( 2*4000w)Product Features:it is a high-performance switch power amplifiers, compact structure reasonable; Each channel can have independently adjustable peak output voltage, make the amplifier can be very handy drive different power of the size of the speaker, and at the same time, each output can respectively set to low resistance or high resistance (70 V / 100 V) has a strong sub-woofers large array system and broader multi-power-level impedance levels; Intelligent protection circuits provide advanced technology to protect the internal circuitry and connection load, in extreme conditions can protect amplifier and speakers.Output power at constant pressure: 4*1600W / 4*2200WTHD: 20 Hz-20 kHz 1W:
