MuxLab 500081 - Dolby Digital to Analog RCA Stereo Audio Converter
The MuxLab 500081 is a professional solution designed to address one of the most common problems in integrating modern audiovisual systems: the incompatibility between the digital outputs of new devices and the analog inputs of traditional sound equipment. Unlike standard converters that only process PCM audio, this advanced device decodes and downmixes multichannel Dolby Digital signals to convert them into a clean, high-fidelity analog stereo signal.
This converter is essential when you need to connect smart TVs, game consoles, Blu-ray players, or satellite receivers that output Dolby audio to amplifiers, Hi-Fi systems, or soundbars that only have RCA (L/R) inputs. Thanks to its internal processing capabilities, you won't have to worry about configuring your TV's output exclusively to PCM; the MuxLab 500081 automatically manages the compressed signal and delivers it ready to listen to.
Its compact and robust design allows for discreet installation behind equipment. It features a selector switch that easily toggles between its two digital inputs (S/PDIF Coaxial and Optical Toslink), providing the flexibility to connect different sources without constantly disconnecting cables. It's the perfect "glue" tool for extending the lifespan of high-quality analog audio equipment in a digital environment.
Main features
-
Certified Dolby Digital Decoding: Capable of receiving 5.1 signals and converting them to 2-channel analog stereo without loss of relevant audio information.
-
Flexible Inputs: It has a Coaxial (S/PDIF) input and an Optical (Toslink) input, selectable by means of a side switch.
-
High Sampling Compatibility: Supports sampling rates of 32, 44.1, 48 and 96 kHz, ensuring compatibility with almost any digital audio source.
-
Standard Analog Output: Dual RCA connectors (Red/White) for universal integration with amplifiers and active speakers.
-
24-bit processing: Handles incoming 24-bit S/PDIF bitstreams on the left and right channels for superior sound quality.
Benefits for the user
The main benefit of the MuxLab 500081 is its ease of use and simplicity . Many users buy generic converters and discover they have no sound when watching Netflix or Disney+ because the broadcast is Dolby; with this device, that problem disappears. It allows you to continue using existing "vintage" analog amplifiers or PA systems with modern sources, saving the cost of upgrading the entire audio system. Furthermore, its compact size and the inclusion of mounting accessories (such as Velcro pads) facilitate a clean and tidy installation.
Use cases
-
Home entertainment: Connect the optical output of a modern LED/OLED TV to a classic 80s/90s stereo amplifier.
-
Classrooms and Conference Rooms: Integrate the audio output of a computer or digital media player into an existing analog public address system.
-
Gaming: Send audio from a next-generation console to self-powered speakers with RCA input.
-
Medical and Corporate Systems: Decoding of audio signals in environments where reliability and compliance with technical standards are required.
Frequently Asked Questions
Does this converter support true 5.1 sound on the output?
No, the device receives a 5.1 (Dolby Digital) signal and performs an intelligent "downmix" to convert it into an analog stereo (2.0) signal, allowing you to listen to all the content through two speakers.
Does it need to be plugged into a power outlet?
Yes, it is an active device that requires an external power supply to process and decode the digital signal. The necessary power supply is included.
Can I connect the optical cable and the coaxial cable at the same time?
Yes, you can have both cables physically connected. The device has a sliding switch that lets you select which of the two inputs you want to listen to at any given time.
Does it work with DTS?
This specific model (500081) is designed for Dolby Digital and LPCM. If your source outputs in DTS, you will need to configure the source to output in Dolby Digital or PCM.
Project description
Digital-to-analog converter (DAC) with Dolby Digital decoding and downmixing capabilities to 2.0 stereo. The device must have selectable coaxial (S/PDIF) and optical (Toslink) digital inputs and a stereo analog output via RCA (L/R) connectors. It must support sampling rates up to 96 kHz and a 24-bit resolution. The unit requires an external 5V DC power supply and must be housed in a compact, flame-retardant ABS enclosure suitable for surface mounting using Velcro or cable ties. Ideal for integrating digital sources into analog amplification systems.
