Overview
The ADC-8434-A Quad Analog Audio to AES Converter is a broadcast quality, modular product
used to convert four analog audio channels to two, 24-bit, unbalanced AES-3id signals. The
ADC-8434-A accepts 4 analog audio signals (2 stereo pairs) and provides 2 copies of each of the
2 AES / EBU output signals.
The conversion from analog to digital is performed with 24-bit precision. The ADC-8434-A
supports sampling rates of 32kHz to 96kHz with AES (DARS) reference, video black reference,
or 48kHz internal reference. The AES output frequency (32kHz to 96kHz) can be determined by
the reference selected as long as it is a valid DARS Audio reference.
