External USB-DAC-Audio Processor, CDD 011. Novelties of our own production


Appearance CDD 011

Audiophile USB player CDD 011 combines digital sound processing on the ADAU1452 audio processor, high-quality digital-to-analog conversion on the AD1934 codec and analog signal preparation by high-performance OPA1632 op amps.

Thanks to the AD1934 codec, it became possible to add a low-frequency channel for a subwoofer with the SuperBass algorithm to the wideband stereo channel. If you don't already have a subwoofer, only connect your audio system to the stereo outputs. They output a broadband stereo channel 10 - 22000 Hz. You can connect ANY digital audio sources to CDD 011 , even exotic I2S via HDMI.
