openGear ADC-8434-A Quad Analog Audio to Dual AES Converter


The ADC-8434-A quad analog audio to dual AES converter is a broadcast quality, modular solution, which converts 4 analog audio channels to 2, 24-bit, unbalanced AES3 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 ADC-8434-A also has internal audio processing with independent channel gain, master stereo gain, sum (mono), and left or right only selection.

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.
