The 7720DAC-A4 is a high-quality, 24-bit, digital to analog audio converter which converts 2 AES/EBU digital signals to 4 balanced analog audio signals. The 7720DAC-A4 has two independent AES/EBU converters. The inputs sample rate supported are 44.1 KHz and 48KHz. All analog audio outputs levels may be set individually from the front panel. Level control is provided via a card edge toggle and the set gain level can be read out from a card edge display for convenience. The full scale digital signal can be calibrated to accommodate peak levels ranging of 12dBu to 25dBu with 0.1dB resolution. The audio DAC features a card edge VU meter for quick confidence monitoring. Four separate level indicators are provided via bargraphs for quick validation of audio program material.
