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.
