KARUNA PREMIUM DDC
Digital to digital converter and Reclocker at top level
KARUNA PREMIUM DDC is our special audio equipment and accessory which is responsible for USB audio data transformation to reduced noise other digital standard like SPDIF ot i2S LVDS.
The device based on XMOS architecture and thanks to the special firmware the capability of these chips is used 100%, the result is an impressive sound quality. Our designers paid special attention to the digital PCB circuits, the PSU parts and for our own designed masterclock management.
We recommend it to those users too, whose source device has only USB audio output and would like to minimize the source unit's noise level problems or using more DAC in the system (working like a digital signal distribution unit).
The user can choose between ultra low level operation mode: only just USB input is switched on and one of the available outputs. Thanks to this solution the unit's noise level minimized, the PCB's other parts are out of operation. Also possible to switch on all of the digital outputs on the same time, handle with this solution more connected digital equipments.
The converter is available in a silver finished aluminum version as well as black anodized aluminum version.
Thanks to the especially selected parts and clock technology our feeling is that we can offer to our customers a warm, fluid, lifelike, airy and smooth sounding digital to analog converter.
