DAC6800+BCA4D, +BCA4ZD

AES Digital Audio to Analog Audio Converters

The DAC6800+ series is a family of high-precision AES to analog audio converters that can accept one or two AES inputs, either balanced or unbalanced, and convert to two or four analog audio outputs respectively. High-quality, 24-bit conversion is supported, along with a variety of other flexible features. Two versions of the module are available:

DAC6800+BCA4D: converts two AES inputs to four analog audio outputs (66 ohms)
DAC6800+BCA4ZD: same as above except provides 600 ohms output impedance

Designed for use in any professional/broadcast installation needing to integrate both AES digital and analog audio sources, these modules are ideally suited for converting AES into analog audio for recording on VTRs, or for input to other devices only supporting analog audio. Another application is cost-effectively monitoring AES feeds by converting them to analog for use with existing analog speakers.

DAC6800+ modules can be controlled at the card edge, or controlled and monitored via CCS Navigator™ software applications, HTTP web browser (with QXFE-series frames only), NUCLEUS™ hardware control panels, or via third-party control applications using SNMP.

Features

Two AES audio inputs with auto-detect and input status feedback (card-edge and CCS)
Balanced or unbalanced AES inputs available
Four analog audio outputs (two stereo pairs)
16-, 20- or 24-bit audio conversion for high-quality audio performance
Supports audio sample rates on AES inputs from 32 to 96 kHz
Output muted when errors detected on AES input to prevent passing bad audio
Choice of 66 ohms or 600 ohm high-impedance analog output module versions
User selection of analog audio output level from 16 dBu (10 dBm) to 28 dBu (22 dBm), in 2 dBu (2 dBm) increments
Supports card-edge and remote control of module (via CCS, Web browser and third-party SNMP-based control systems)
