RDL specifies distortion of 0.0006%, residual noise below -135 dB and frequency response flat to ±0.05 dB from 20 Hz to 20 kHz. External sync inputs, peak and average metering with peak store, and front-panel rate and bit-depth selection make it a complete A\/D converter for broadcast and production facilities.\u003c\/p\u003e\u003ch2\u003eHow does it work?\u003c\/h2\u003e\u003cp\u003e\u003cimg src=\"https:\/\/rdlnet.com\/wp-content\/uploads\/2024\/01\/hr-adc1.jpg\" alt=\"RDL HR-ADC1 broadcast analog to digital audio converter\" style=\"max-width:100%;height:auto\" loading=\"lazy\"\u003e\u003c\/p\u003e\u003cp\u003eThe HR-ADC1 accepts balanced +4 dBu or unbalanced -10 dBV stereo audio through rear-panel XLR or RCA jacks or a detachable terminal block. Front-panel LEFT and RIGHT controls trim the input gain to set the desired average level for conversion. The digital output format is chosen with a rear-panel switch and appears on the matching transformer-isolated XLR (AES\/EBU), RCA (S\/PDIF) or BNC (AES-3ID) jack. An external AES\/EBU, AES-3ID or S\/PDIF sync source can be connected on the rear panel; when valid sync is present the EXTERNAL SYNC LOCK LED lights and the SYNC button locks conversion to it. Without external sync, the converter runs at the sample rate selected with the front-panel RATE button (44.1 kHz to 192 kHz) and the bit depth selected with the BITS button (16, 20 or 24 bits). The meter can show peak or VU average response with a 0 dB reference of -14, -16, -18 or -20 dBFS, and peaks from -10 dBFS to 0 dBFS display separately with flash, 1\/3-second hold, 2\/3-second hold or store modes. Programming selections are saved automatically after five seconds and retained when the unit is re-powered. The HR-ADC1 runs on 24 Vdc at 300 mA through the terminal block or dc jack; RDL recommends the PS-24AS (USA) or \u003ca href=\"https:\/\/creationnetworks.net\/products\/rdl-ps-24ax\"\u003eRDL PS-24AX\u003c\/a\u003e (international) supply, which is not included.
