Miranda DAC-1721 Dual AES to analog audio converter - DAC-1721
The DAC-1721 is high-quality, 24-bit, digital to analog audio converter which allows conversion of two AES digital signal into to two stereo analog audio signals. The DAC-1721 is a dual input converter card. The input sampling rates can be up to 100 kHz, including 32 kHz, 44.1 kHz, 48 kHz and 96 kHz. An internal digital EBU tone generator facilitates alignment of audio levels. All analog audio output levels may be set individually. A digital 50/15 µs de-emphasis stage may be selected manually or automatically according to the channel status. Input status is also available indicating input audio signal presence or overload. The DAC-1721 is compatible with both AES3 and AES-3id digital audio standards.
