ZHC348-0440DA Digital/Analog Convertor

1. Overview

ZHC338-0440DA audio digital/analog converter is a professional broadcast-grade audio signal digital/analog conversion equipment. The device converts the input four-channel AES/EBU digital audio signal into four-channel analog audio stereo signal output, which can adapt to the audio of various digital sampling modes in 32KHz-192KHz, 16Bit-24Bit. The device uses the industry's top chip, excellent performance, the signal-to-noise ratio can reach more than 100dB, and the distortion is less than 0.01%. On the front panel, you can select one of them for headphone monitoring and LED monitoring of the audio signal status. It adopts dual power supply that can be automatically switched to improve the reliability of the equipment.
