Elecbee AK4118 Digital Audio Receiver Board 24-Bit 192kHz, BNC RCA Optical AES/EBU to I2S, 20-Pin XMOS Amanero Interface, OLED

AK4118 DIGITAL AUDIO RECEIVER: Receives compatible S/PDIF and AES/EBU digital audio signals and outputs I2S digital audio for a suitable downstream DAC. This interface board does not provide a confirmed analog audio output or directly drive headphones or speakers.

24-BIT 192KHZ RECEIVER PATH: Supports supplier-specified sample rates from 44.1kHz to 192kHz at up to 24-bit through BNC coaxial, RCA coaxial, optical and AES/EBU inputs. Actual lock range depends on the source signal and board configuration.

I2S DIGITAL AUDIO OUTPUT: Routes the received digital audio stream to a compatible external DAC through an I2S/IIS interface. Verify master clock, bit clock, word clock, audio data, logic voltage and pin assignment before connecting another board.

OPTIONAL USB AUDIO EXPANSION: A double-row 20-pin interface accepts a compatible XMOS or Amanero-style USB audio module. With suitable hardware and software, the supplier specifies PCM up to 384kHz/32-bit and DSD64, DSD128 and DSD256; the USB module is not included.

OLED DISPLAY AND 5V POWER: The 1.3-inch OLED displays operating and sampling status, while selected settings are automatically retained. The approximately 111 × 49.5mm board requires a stable, correctly polarized DC 5V supply.
