1. INTRODUCTION

The Essence HDACC II-4K is designed to allow multiple analog/digital
audio sources to be controlled, switched and output to a variety of
analog/digital audio components. With video support up to 6G at
4K2K and audio sampling rate converter up to 384KHz this device has

an array of unbeatable features you can’t nd in any other product

on the market. Also it supports 2CH LPCM audio, HDMI, USB Audio 2.0,

Optical and Coaxial input/output with both ADC and DAC functions.

USB supports Native DSD playback (Direct Stream Digital) and DOP
(DSD over PCM) decoding, with high sampling frequency to perform
high quality conversion and lower the probability of distortion.

For professional applications, the headphone output with built-

in amplier and XLR (Low noise Professional Balance) output offer

unparalleled audio quality. Traditional 3.5mm earphone jack analog
input and stereo RCA output with a highly accurate PLL and low jitter
reduction clock system enables users with total improvement over
the original sound. OLED display of sample rates with on-panel and IR

remote control provide users with on-the-y adjustment capability.

Note: USB DSD format of this unit supports Native DSD 2.8 MHz (DSD64)
and DSD 5.6 MHz (DSD128).
