Product Description

Oppo UDP-203 Audiocom Reference 4K UHD Blu-ray player is a modified version of Oppo UDP-203 delivers extraordinary performance from 1080p and 4K video with remarkable sound quality from HDMI and coaxial digital outputs.

Reference Model

This modified reference version of the Oppo UDP-203 4K UHD Blu-ray Player benefits from an upgraded linear power supply for Audio & Video Circuitry as well as a 137 fs Jitter Clock for OP8941 SoC. 203 Reference obtains full advantage of the OPPO’s dynamic quad-core photo processing and sizes on this platform by integrating a unique version linear power supply, a femtosecond clock.system, improved disc read accuracy, and circuitry housed in a quiet mechanical and electrical environment.

Linear Power Supply

Conventional 4K Blu-ray players use a switch-mode power supply (SMPS) since it is value for money and easier to apply. However SMPS are noisy due to the high-frequency switching, and this is manifest by noise on the power supplies as well as RFI/EMI noise. The 203 reference uses a custom linear power supply with multiple regulated supplies to deliver clean power to the video and audio circuitry.

All spectrum of the players performance is considerably improved. Video playback has better resolution, greater depth, more detail, natural contrast, reduced picture noise, colour purity and improved image stability. There is noticeable development in digital and analogue audio, with greater resolution, better dynamics, enhanced sound-staging, and more natural harmonics.

Low Jitter Clock

It is widely recognised that low jitter clocks improve performance for audio, but less recognised is that low jitter is vital to achieve the best performance for video. For 4K Blu-ray players the clock jitter in video signal processing system can be anything from 100-300 picoseconds resulting in a reduced picture quality and sound. In the 203 Reference player we utilise a custom, very low jitter clock for the OP8591 System on Chip with a jitter performance of 137 Femtoseconds ( 0.137 Picoseconds). As a result, image quality is natural with a crisper, greatly-defined photo, digital and analogue audio is more dynamic, complete and articulate.

EMI/RFI Reduction

Audiocom discovered that reducing interference fields and resonances in the disc transport improves performance. For the 4K disc loader, a special layer of material coating is applied to reduce electromagnetic (RFI/EMI) energy and cancel out unwanted resonance. The result is improved disc read accuracy, with improved colours and textures for a more realistic picture quality. The operating conditions of video and audio are much improved when they can work in quiet environment.

Inside any Blu-ray player the video processing generates its own noise as well as succumbing to external noise which can affect the players overall performance.To achieve silent electrical conditions, the 203 reference uses materials to shield and absorb the unwanted EMI/RFI and motorised energy to constantly acheive the highest performance regardless of the surroundings.
