Overview

The 9930DAC-AES75-RG 75-Ohm (Unbalanced) 2-Pair AES-To-4-Channel Analog Audio Converter with Remote Gain Control is a broadcast-quality AES Digital-To-Analog Converter (DAC) that provides four professional-level balanced analog audio outputs. It also provides a 2x1 reclocked distribution amplifier for each AES input channel.

The 9930DAC-AES75-RG supports audio sampling frequencies from 32kHz to 96kHz. Cable equalization and reclocking techniques enable the 9930DAC-AES75-RG to recover the incoming digital audio signal reliably.

A built-in DSP allows mono-mix and L/R-only outputs.The DSP attenuation function allows overall gain (stereo ganged) trim (offset) via DashBoard™ remote control.

The space-saving design and very low power consumption of the
9930DAC-AES75-RG provides for high density installation.
