4 channel amplifier A-4450

4 channel pa speaker power amplifier A4450

Apply ultra dynamic floating pole technology,it’s able to output rated power of greater than 37% of the dynamic signal instantly,no interrupting electric wave,no distortion.
The digital limiter function,input signal it able input from 0.775 to 8V,the constant of full output power,greatly improving the reliability of amplifier,meanwhile protecting the speaker as well.
When overheat working within a certain period of time,there will show low frequency point digital limited status,increasing reliability,while extending protect not suddenly shotting down working time.
Each channel with pressure limiting control function,electric wave its not gong to have a long time being interrupted,reduced the heat,used more safer.
With the changes in the music signal synchronization hyperbolic obtain maximum efficiency,minimal distortion,power efficiency is up to 75%.
Integrated steel,reinforced parts,perfect connection,professional Speakon socket,adapted enginnering and touring.
