Audio Technologies Inc. DDA-106XLR
Distribution Amp, Digital, 1x6, XLR, AES/EBU


The Audio Technologies Inc Series 2 Digital Audio Distribution Amplifiers give you new features and flexibility. Now you can distribute digital audio at up to 192kHz sample rates with incredibly low jitter and ultra-short propagation delay. Switchable inputs let you choose from multiple input streams. Selectable reclocking lets you precisely regenerate a pristine input signal or handle Surround-encoded audio. Sample Rate, Word Length, Fault Diagnostic and Pro/Consumer displays tell you your audio is clean or let you know why it's not. Push-button input EQ optimizes for long input cables. Loop-thru connectors let you stack units for even more outputs or seamlessly insert a DA into your digital workflow.
