DTS Digital to Analog Audio Decoder Converter with Optical Fibre and Coaxial Inputs for Dolby AC-3 to 5.1 Channel Output, Compatible with PCs, Blu-ray Players, Game Consoles and HD Set-Top Boxes, Black (105 x 75 x 25mm)
DTS and Dolby Digital Audio Decoder: Convert Optical and Coaxial Signals to 5.1-Channel Analogue Output

This DTS digital to analogue audio decoder is a versatile interface designed to unlock multi-channel audio from modern digital sources for use with a wider range of audio systems. It specifically decodes the source code from DTS and Dolby Digital (AC-3) audio streams, converting the digital signal into a full 5.1-channel analogue output. This functionality is essential for users with amplifiers or speaker systems that only accept analogue inputs, allowing them to enjoy surround sound from devices like high-definition media players, Blu-ray discs, and games consoles. Its application extends from home cinema setups to installations in schools, public venues, and other spaces seeking impactful audio. The decoder also features a secondary function, processing standard two-channel stereo analogue signals and upmixing them to a 5.1-channel configuration via its internal audio chip.
Features and Construction

The decoder is engineered for reliable audio conversion and flexible connectivity in a compact form factor. It provides a straightforward solution for integrating modern digital audio sources with existing or traditional analogue audio equipment.
Material and Build
The unit utilises a global audio decoder chip to process the DTS and Dolby Digital source code. This chip is central to its core function of converting encoded digital audio into discrete multi-channel analogue signals. The construction houses this chip along with the necessary circuitry for the multiple input and output ports. The build prioritises a functional, space-efficient design, resulting in a product that is described as exquisite, compact, and convenient for plug-and-play use with strong mobility.
Size and Practical Fit
With external dimensions of 105mm in width, 75mm in depth, and 25mm in height, the decoder has a notably slim profile. This compact size allows it to be discreetly placed within an entertainment unit, on a shelf, or alongside other AV components without occupying significant space. The small footprint and low profile contribute to its plug-and-play practicality, making it easy to install and relocate as part of a temporary or permanent audio setup.
Uses and Placement

This decoder serves as a critical bridge between digital audio-output devices and analogue multi-channel speaker systems, suitable for various environments and source equipment.
Event or Professional Use
For installations in schools, public squares, concert halls, or small theatres, this decoder can process the digital audio feed from a media player or computer to drive a more powerful, multi-channel analogue PA or speaker system. This enables these venues to achieve the spatial and dynamic impact of Dolby or DTS sound fields from standard digital sources, enhancing presentations, film screenings, or musical playback with surround sound effects.
Everyday Home Use
In a domestic setting, it connects seamlessly to a wide range of common devices. Home users can connect their PC, laptop, PlayStation 3, Xbox 360, high-definition set-top box, Blu-ray player, or network media player (like a DM500/DM800) via optical or coaxial cable. The decoder then outputs the decoded signal to a standard home theatre amplifier or an active 5.1-channel speaker set, bringing cinema-style surround sound to movie nights and gaming sessions without requiring a fully digital AV receiver.
Benefits and Buying Value

The decoder provides a cost-effective and practical upgrade path for experiencing surround sound, focusing on compatibility, simplicity, and audio performance based on its stated specifications.
Reuse and Low Maintenance
The product adds functionality to existing audio equipment. It allows users to continue using their current analogue amplifier and speaker system while adding compatibility with new digital sources, extending the useful life of their AV investment. As a solid-state electronic device with no moving parts and simple connectivity, it requires minimal maintenance—essentially just keeping connections clean and secure.
Why Choose This Product
The key advantage lies in its specific, focused functionality. It performs a dedicated conversion task with supported technical performance, including a 120dB signal-to-noise ratio and a 20Hz-20KHz frequency response. The inclusion of multiple input types (two optical, one coaxial, one stereo) offers exceptional connection flexibility for different devices. The package is complete, containing the decoder, power supply, an optical cable, and a manual, providing everything needed for immediate setup and use.
