Description
Clarus CODA CDAC-100 Portable USB DAC and Headphone Amplifier
Put a dedicated DAC and headphone amplifier between your digital music and your headphones. CODA combines an ESS SABRE converter, a 3.5 mm stereo output and simple side-button controls in a compact aluminum body.
Dedicated conversion
A compact upgrade for wired listening
The CODA bypasses the source device's internal DAC and amplifier. Its ESS Professional Series SABRE converter supports PCM files up to 32-bit/384 kHz, plus DSD carried as DoP64 or DoP128. The Class G amplifier is designed for low power consumption during mobile listening.
Daily use
Connect, select and listen
Use the built-in USB-A connector or the included 15 cm USB-C adapter with a compatible source. Connect your headphones first, then select CODA as the computer's audio output. A removable cap and included zipper case help keep the small listening setup together between sessions.
