The input and each output support AES\/EBU, S\/PDIF or AES-3ID, with format conversion for the selected output and operation up to 24 bits and 192 kHz. RDL's Sure-Lok auto-recovery supervision keeps digital lock stable, making it a dependable choice for broadcast and production distribution.\u003c\/p\u003e\u003ch2\u003eHow does it work?\u003c\/h2\u003e\u003cp\u003e\u003cimg src=\"https:\/\/rdlnet.com\/wp-content\/uploads\/2024\/01\/hr-dda4.jpg\" alt=\"RDL HR-DDA4 1x4 AES\/EBU and S\/PDIF digital audio distributor\" style=\"max-width:100%;height:auto\" loading=\"lazy\"\u003e\u003c\/p\u003e\u003cp\u003eThe HR-DDA4 automatically detects a valid signal on any of its four input jacks: S\/PDIF optical, S\/PDIF coaxial, AES-3ID or AES\/EBU. The input is decoded, reclocked and retransmitted to four individually buffered outputs. Each output has its own rear-panel switch that selects AES\/EBU, S\/PDIF coaxial or AES-3ID and enables the matching jack with any required electrical and data format conversion. AES\/EBU input and outputs are 110 Ω and transformer isolated, while the S\/PDIF coaxial and AES-3ID jacks are 75 Ω terminated. Front-panel LEDs show the incoming format and sample rate, from 32 kHz to 192 kHz, whenever a valid source is received without phase-lock or bit errors. Sure-Lok supervision monitors possible causes of latch-up and re-initiates digital signal lock to keep distribution stable in professional environments. The unit runs on ground-referenced 24 Vdc at 50 mA through the terminal block or dc jack, with a front-panel power switch; RDL recommends the PS-24AS (USA) or \u003ca href=\"https:\/\/creationnetworks.net\/products\/rdl-ps-24ax\"\u003eRDL PS-24AX\u003c\/a\u003e (international) supply.
