DTS Digital Audio Decoder for 5.1 Channel Dolby AC-3 Conversion with Optical Coaxial Inputs

This DTS digital to analogue audio decoder bridges the gap between modern digital audio sources and older 5.1 channel sound systems. It accepts optical, coaxial, and stereo inputs from devices such as Blu-ray DVD players, HD set-top boxes, game consoles like PS3 and Xbox 360, and network players. The decoder converts DTS and AC-3 encoded digital signals into a full analogue 5.1 channel output, restoring the immersive Dolby sound field for home theatre, classroom, or professional use. With a compact size of 105x75x25mm and a black finish, it fits neatly beside other AV equipment.

Features and Construction

Built around a global audio decoder chipset, this unit provides reliable decoding of DTS and Dolby Digital source audio. The interface is designed for straightforward connection and switching between multiple sources.

Decoding and Sound Processing

The decoder handles DTS and AC-3 digital audio source code, converting it to analogue 5.1 channel signals. It also converts analogue stereo (R/L) signals into a 5.1 channel output via an audio processing chip. The signal-to-noise ratio is 120dB, with a resolution of 80dB at 1KHz and a frequency response of 20Hz~20KHz +/- 0.5dB. Analogue output level is 2.2V.

Input and Output Interfaces

Input options include 2 SPDIF optical fibre inputs, 1 coaxial input, and 1 stereo input. Outputs are provided for centre (CEN), front left (FL), front right (FR), rear left (SL), rear right (SR), and heavy bass (SW). There is also a USB 5V output for powering compatible 5.1 earphones.

Size and Physical Design

The unit measures 105 x 75 x 25mm (10.7 x 8 x 2.5cm), making it compact and portable. It is designed for plug-and-play use with no complex setup required.

Uses and Placement

This decoder is suitable for a wide range of settings where digital audio needs to be routed to analogue multi-channel speakers. Its multiple inputs make it adaptable to various source devices.

Home Theatre and Gaming

Connect to a Blu-ray DVD player, HD-CD player, or gaming console such as PS3 or Xbox 360 to decode game audio or film soundtracks into 5.1 channel surround sound. The one-key switch allows quick toggling between stereo and 5.1 output.

Professional and Educational Use

In schools, conference halls, or cinemas, the decoder can take digital audio from high-definition players or set-top boxes and feed it into existing analogue PA or sound systems, restoring DTS/Dolby sound fields for presentations or screenings.

Computer and Desktop Integration

For PC or notebook users, the decoder connects via optical or coaxial output to deliver 5.1 audio from media files or streaming services, upgrading desktop audio without replacing the entire speaker system.

Benefits and Buying Value

This decoder offers practical value by extending the life of existing analogue 5.1 speaker systems while supporting modern digital sources. Its straightforward operation and compact design reduce clutter.

Ease of Setup and Use

Plug and play design means no drivers or software installation is needed. The multi-channel one-key switch provides instant switching between stereo and 5.1 modes, and the remote wakeup function adds convenience.

Versatility and Connectivity

With two optical inputs, one coaxial, and one stereo input, the decoder can handle up to four different source devices simultaneously, making it a central hub for audio routing. The USB 5V output also powers external 5.1 headphones if needed.
