DAC-8516
AES / EBU to Analog Audio Converter
Program stream AES / EBU to analog audio conversion with 24-bit
DAC resolution.
The RossGear DAC-8516 AES / EBU to Analog Audio Converter is a broadcast quality
modular product used to convert 20 or 24-bit AES-3id (coaxial) signals to analog audio.
The DAC-8516 accepts one 32, 44.1 or 48 kHz sample rate unbalanced AES signal and
provides two outputs of stereo (A, B) analog audio.
Digital AES / EBU audio is input through a BNC connector on the rear of the frame. The
signal is auto-equalized, relocked and then converted to analog audio using a state-of-the-art
128X oversampled Delta Sigma Modulator. Two identical copies of the signal are output via
the plug-on module BNC to terminal block adapter. Input signal and internal processing errors
are detected and reported on the SMPTE 269M fault reporting bus. Error presence
is displayed on a card-edge LED.
Acombination of Headroom jumper (18dB or 24dB) and Level Adjust potentiometers
(+/-6dB, one for each channel) provide an output level range of +12 dBu to +27 dBu.
Auto-detection Digital De-emphasis is available for all data rates.
ADC-8532
Analog Audio to AES / EBU Converter
A 24-bit analog to AES / EBU converter. Perfect for broadcast stream
conversion applications.
The RossGear ADC-8532 Analog Audio to AES / EBU Converter is a broadcast quality
modular product used to convert analog audio to 20 or 24-bit AES-3id (coaxial) signals.
The ADC-8532 accepts one stereo (A, B) analog audio input and outputs four unbalanced
AES signals at 32, 44.1 or 48 kHz sample rates.
The balanced analog audio signal is input through a terminal block to BNC adapter module
on the rear frame. Infinitely variable input level adjustments from +14 to +30 dBu are
available for the input analog audio signal. The Ato D converter uses a state of the art
256X oversampling delta sigma modulator and filtering circuit to produce four identical
high-quality AES streams. Reference signal or processing errors are detected and reported
on the card-edge LEDs. For 48 kHz AES, the RossGear
ADC-8532 is capable of referencing
to either an external analog video or
AES (DARS) reference. Referencing
to the external AES reference
guarantees a properly phased
AES output.
