High resolution ultra-low jitter quad 1x4 AES/EBU digital audio distribution amplifier. The ATI model DDA416-XLR gives you four independent 1x4 AES/EBU digital audio distribution amplifiers, each one capable of handling AES3 audio with sample rates from 32 to 192kHz. Operation of the unit is simple and straightforward and it is housed in a rugged 2U rack mount enclosure. All audio connections are made directly to the unit’s rear panel XLR connectors, and no special breakout cables are required. The DDA416-XLR features flexible signal routing. Rear panel accessible DIP switches let you assign each bank of 4 outputs to any of the 4 inputs. This lets you configure the DDA as a dual 1x8 or a 1x16. Other asymmetrical routing combinations, such as 1x4 plus 1x12, are also possible. Summary alarm LEDs indicate faults occurring on any input, regardless of the audio routing. The ultra-low jitter performance of the DDA416-XLR makes it an exceptional performer in any critical audio application. It is ruggedly designed for years of professional service.
