OPPO UDP-203 Audiocom signature is a world reference native 4K UHD Blu-ray player capable of remarkable picture quality with stunning digital audio from movies and music delivering the ultimate home cinema experience. The UDP-203 Signature extracts the full measure of performance from video, HDMI digital audio (including optical and coaxial outputs), as well as delivering superb sound quality from analogue audio.
There are several reasons why the 203 signature pushes the technology above any other 4K UHD native universal Blu-ray player. There is absolutely no compromise made in the quality of components and design, all units are meticulously assembled for the best possible performance.
Ordinarily Blu-ray player’s use switch mode power supplies (SMPS). The switching from these power supplies introduce noise which inevitably is introduced to the circuitry. Due to the high frequency switching of these supplies they also create RFI which in turn affects the video and audio signal.
All commercially available 4K Blu-ray players use standard clocks for the video processing. A “High-End” Blu-ray player may employ a low jitter clock for the audio, but the System on Chip clock (SoC) is a standard clock oscillator circuit with jitter values typically of 100-300 picoseconds. In a similar way that a low jitter clock will reduce phase noise (jitter) for the audio signal, a very low jitter clock for video processing will reduce jitter and noise in the video spectrum.
We discovered during disc playback that reducing interference fields and resonances in the disc transport could improve the performance of video and audio quality. For the 4K disc loader we apply a specialist material layer coating developed to absorb electromagnetic (RFI/EMI) energy, and cancel out unwanted resonances. The result is improved disc read accuracy, with improved colours and textures for a more realistic picture quality.
In conventional audio/video equipment a traditional mains filter is used and while the better quality filters remove a degree of noise they are inadequate, often introducing negative effects. For the 203 signature we utilize two different types of unconventional solutions that remove quantum noise and provide uninhibited current flow. The benefits are a picture quality that is more immersive and palpable. The sound has an enhanced perception of space and dimensionality, with improved coherence and naturalness.
The Audiocom 203 Signature edition includes:
■ New top-end linear power supply with multiple low noise regulated power supplies for video and audio circuitry.
■ New audio grade Cryofuse, non-magnetic, anti-resonance.
■ New custom AC shunt device improves current flow.
■ Vastly improved, error and jitter free data processing thanks to 77 Femtosecond Reference clock (0.077 psec) for OP8591 SoC (Video, digital audio, DAC input).
■ 4K disc loader modifications for improved disc reading accuracy.
■ New high quality Furutech IEC inlet with UP-OCC internal wiring to power supply.
■ New material layer coating for chassis that uses piezoelectric damping and absorbs electromagnetic (RFI/EMI) energy.
