HR-ADC1

RDL HR-ADC1 - Broadcast-Quality Analog to Digital Audio Converter

The RDL HR-ADC1 is a high-performance analog-to-digital converter designed for broadcast, studio, and professional AV applications requiring exceptional audio fidelity. It supports balanced (+4 dBu) and unbalanced (-10 dBV) stereo inputs and provides digital outputs in AES/EBU, AES-3ID, and S/PDIF formats.

HR-ADC1 delivers outstanding audio performance with ultra-low distortion (0.0006%), noise (-135 dB), and flat frequency response (±0.05 dB). It allows selection of sample rate and bit depth up to 24 bits / 192 kHz and supports external digital sync sources.

Advanced metering features include selectable average (VU) or peak response, with 0 dBFS reference levels settable to -14, -16, -18, or -20 dBFS. Peak values can be stored or displayed with adjustable flash durations, enabling precise monitoring without external tools.
