DTS Digital to Analogue Audio Decoder: Convert Fibre Optic or Coaxial to 5.1 Channel Surround Sound

This DTS digital to analogue audio decoder bridges the gap between modern digital audio sources and traditional analogue sound systems. It accepts optical (fibre) and coaxial digital inputs, as well as a stereo analogue input, and converts them into a full 5.1 channel analogue output. Whether you are connecting a set-top box, Blu-ray DVD player, PS3, XBOX360, or PC, this unit lets you enjoy DTS and Dolby AC-3 sound fields through amplifiers or speakers that only have RCA inputs. The decoder is compact at 105×75x25mm, making it easy to place near your audio equipment without taking up much space.

Features and Construction

This audio converter uses a global decoder chip to handle DTS and Dolby Digital source code, ensuring faithful reproduction of the original surround sound. With multiple input types and a simple one-button switch, it is designed for straightforward integration into existing setups.

Input and Output Connectivity

The decoder offers two SPDIF optical inputs, one coaxial input, and one stereo analogue input. On the output side, it provides six RCA channels: front left (FL), front right (FR), rear left (SL), rear right (SR), centre (CEN), and subwoofer (SW). A USB 5V output is included for powering external 5.1 headphones that require a USB supply.

Decoding and Audio Performance

It decodes DTS/AC-3 source code into analogue 5.1 channel audio, and can also convert a stereo analogue signal into a simulated 5.1 sound field. The unit achieves a signal-to-noise ratio of 120db and a resolution of 80db at 1KHz, with a frequency response of 20Hz–20KHz ±0.5db. Output level is 2.2V.

Compact and Portable Build

The unit measures 105×75x25mm, making it compact enough to sit beside a TV, media player, or amplifier. The simple one-key switch allows for fast toggling between stereo and 5.1 modes, and the product is designed for plug-and-play operation with no software installation needed.

Uses and Placement

This decoder is intended for setups where a digital audio source must feed an amplifier or active speakers that only have analogue RCA inputs. It is commonly used in home theatre systems, PC gaming rigs, and professional audio environments.

Home Cinema and Gaming

Connect it to a Blu-ray DVD player, PS3, XBOX360, or high-definition set-top box to decode DTS or Dolby Digital bitstreams and send a 5.1 analogue signal to a multi-channel amplifier. The optical and coaxial inputs accommodate most digital output connectors found on these devices.

PC and Multimedia Systems

For a PC or laptop with an S/PDIF output, this decoder enables 5.1 audio through analogue speakers or a home receiver. The additional stereo input allows switching to a second audio source like a music player.

Professional and Venue Audio

In schools, meeting rooms, or small halls, the decoder can process digital audio from a media player or DM500/DM800 satellite receiver and feed it to a multi-channel PA system, restoring the DTS or Dolby sound field for an immersive listening experience.

Benefits and Buying Value

This product offers a straightforward way to add surround sound decoding capability to analogue-only audio systems. Its multiple inputs and compact design make it a flexible and practical addition to many AV setups.

Multi-Input Flexibility

With two optical inputs, one coaxial input, and one stereo analogue input, you can connect several digital and analogue sources simultaneously and switch between them using the one-key control. This reduces the need for additional switching equipment.

Reuse and Low Maintenance

The solid-state design requires no regular maintenance beyond keeping connectors clean. The decoder is plug-and-play, so it can be repositioned or reconnected in different setups without configuration changes.

Why Choose This Product

If you have an older amplifier or powered speakers that lack digital inputs, this decoder restores the ability to enjoy DTS and Dolby Digital 5.1 audio from modern sources. The inclusion of optical, coaxial, and stereo inputs, plus a USB power output for headphones, gives you broad compatibility without needing multiple adaptors.
