DAC-8516
• 24-bit DAC resolution
AES / EBU to Analog Audio Converter
Program stream AES / EBU to analog audio conversion with 24-bit
DAC resolution.
• Operates at 32, 44.1 and
48kHz sampling rates
• Auto EQ > 610m (2,000 ft.)
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.
• Low jitter performance
through EQ range
• Input range from 100mV
to 2.5V pp
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.
• Adjustable audio output level
-12 to -30dBFS
• Input OK and error indicators
• Two stereo audio outputs
• 5-year transferable warranty
• Power: 3.5 Watts
A combination 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
• 24-bit conversion
Analog Audio to AES / EBU Converter
A 24-bit analog to AES / EBU converter. Perfect for broadcast stream
conversion applications.
• Selectable 32, 44.1, 48kHz
sampling rates
• +14 to +30dBu adjustable
input range
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.
• 106dB S/N un-weighted
• AES / Video Ref Input OK and
error indicators
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 A to 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.
• Jitter <1ns
• Four AES outputs
• 5-year transferable warranty
• Power: 5.0 Watts
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.
