Fast conversion that's widely compatible

In the D03K, the MS8416T digital audio receiver allows support for the entire range from 32kHz to 192kHz sampling frequencies. The MS4344 DAC supports up to 192kHz/24bit audio, and other functions facilitating the digital-to-analog conversion including: interpolation filter, multi-bit digital-to-analog conversion, and analog output filter. Together, they allow the D03K to support most audio formats. The D03K can be used with: digital TV output, AV receivers, CD/DVD/Blu-ray players, digital mixing consoles, digital signal processors, set-top boxes, computers, and car audio.

High Fidelity transmission from a dual-channel op-amp

The D03K utilizes the SG358, a high-performance dual-channel output rail-to-rail CMOS op-amp, which is widely used in mobile audio applications and ensures greater compatibility with a variety of devices.

Auto detection, and get a status report with just a glance

When a non-PCM input signal is detected, the LOCKED indicator light will not light up and the output sound will be completely muted to avoid any unintended harsh audio.

Red light for power indicator; Blue LOCKED indicator light for valid input signal

A tiny package useful for many scenarios

The unibody aluminum alloy construction allows the D03K to remain conveniently small without sacrificing rigidity. And small touches like the dust-proof optical receiver and gold-plated coaxial receiver ensure signals are received without fail.
