Overview

The DAC-162 is an AES/EBU digital to analog audio converter designed for broadcast
use. It provides digital to analog audio conversion along with AES/EBU signal distribution.

The DAC-162 supports audio sampling frequencies from 30k Hz to 192 kHz. It converts the
incoming AES/EBU digital audio signal to a stereo analog audio signal using 24 bit conversion
technology.

Cable equalization and reclocking techniques enable the DAC-162 to recover the incoming
digital audio signal reliably.

The DAC-162 is designed for use in the openGear 8310-C series frames.
