Digital Interface Module SRC AK4137 I2S USB Optical 32bit 384kHz DSD256 avec Écran
This extremely versatile digital interface module is equipped with an AK4137EQ AKM Sampling Rate Converter (SRC) chip at the heart of its architecture. This chip supports high sampling rates up to 32bit 768kHz in PCM and up to DSD256 and will allow you to enjoy your high resolution files for an incredibly accurate music experience. On the connector side, there is a Toslink optical input and an I2S output on a 20-pin connector. It is then possible to add AES, Coaxial, BNC and USB input via an XMOS or Amanero interface. The interface managing SPDIF flows is an AKM AK4118AEQ chip, which considerably reduces jitter. In the same idea of reducing the jitter, the module includes two clocks of different frequencies for a perfect synchronization of the signals.
The module is delivered with an OLED screen displaying the active source, file format, sampling rate or filter. The display simply connects to a dedicated port.
It is possible to select the origin of the MCLK signal. The MCLK signal comes from the AK4137 chip, the contacts J1 being connected. By removing the solder between these contacts J1 and connecting the contacts J2, the MCLK signal will then come from the oscillators.
