ADC-1722
Dual Analog Audio to AES Converter
The ADC-1722 is a high-quality, 24-bit, analog to digital audio converter which allows conversion of two stereo analog audio channel into two AES type digital signals. Sampling rates can be set to 32, 48 or 96 kHz by an internal clock or an external reference signal. An internal digital EBU tone generator facilitates alignment of audio levels. User-defined channel identification data may be encoded in the AES status bits. An input audio signal status is also available indicating input signal silence or overload. The ADC-1722 is compatible with both AES3 and AES-3id digital audio standards.
FEATURES
- Single or dual stereo channel use (select proper rear)
- 1 external reference input (Word Clock or AES3-id DARS)
- 2 AES outputs per stereo channel
- Balanced AES3 or unbalanced AES3-id outputs
- 24-bit A to D conversion (16, 20 or 24 bits output word length)
- 32, 48 and 96 kHz sampling rates
- -96 to +12 dB of gain adjustment (by 0.5 dB steps)
- 0 dBFS programmable analog (0 to +28 dBu, 1 dB steps) level mapping
- Internal EBU tone generator
- Adjustable silence detection threshold
- Overload detection and reporting
