ZHC338-0404AD four-way audio analog-to-digital converter Introduction: The ZHC338-0404AD audio analog/digital converter is a professional broadcast audio signal analog/digital conversion device. The device converts four analog audio stereo signals into four AES/EBU digital audio signal outputs. The device uses the industry's top chip, excellent performance, signal-to-noise ratio can reach more than 100dB, distortion is less than 0.01%. On the front panel, you can select one of the statuses for headphone monitoring and LED monitoring of audio signals. The dual-supply power supply that can be automatically switched improves the reliability of the device. Technical Parameters: specification 1. Analog audio input impedance (balance) 600Ω 2.
