Overview

The output power of the NA735 parking lot broadcasting network constant voltage amplifier is 120W, and the output frequency response range is 60-18KHz. The device is equipped with an abnormal operation protection warning function. When the input signal is too large, the load is too heavy, the temperature is too high, or the circuit is short circuited, the indicator light will prompt, indicating * reliability. The shell adopts a 2U standard chassis design, with aluminum alloy panels, which are beautiful and practical.
