WENTRONIC Goobay 58493 digital-to-analog audio converter, up to 192 kHz, Black

The WENTRONIC Goobay 58493 digital-to-analog audio converter accepts digital audio input via coaxial cable or TOSLINK optical input and produces a stereo analogue output through phono/RCA connectors or a 3.5 mm jack. The device supports sampling rates up to 192 kHz and is finished in black, enabling connection of modern digital sources such as TVs, media players or set-top boxes to analog amplifiers or speakers.

Advantages

This converter provides reliable D/A conversion for connecting digital audio sources to analog playback systems, supporting high sampling rates up to 192 kHz for improved signal fidelity. It offers both coaxial and TOSLINK inputs for flexible source compatibility and dual analogue outputs (RCA and 3.5 mm) for connection to a variety of amplifiers and speakers. The compact black housing is suitable for simple integration into home AV setups.

Suitable for

• Connecting a TV with optical output to an analog AV receiver or powered speakers
• Integrating media players or set-top boxes into older stereo systems
• Converting digital coaxial output from CD players or digital transports to analogue signals

When it may not be suitable

This converter does not provide advanced processing such as upmixing, tone control or room correction; it performs straightforward digital-to-analogue conversion. It also does not include wireless streaming, HDMI inputs/outputs, or a built-in headphone amplifier with high-power output, so it may not meet needs for wireless audio distribution or high-drive headphone use.

Key specifications

• Digital inputs: coaxial (RCA) and TOSLINK optical
• Analogue outputs: phono/RCA stereo and 3.5 mm stereo jack
• Maximum supported sampling rate: up to 192 kHz
• Signal conversion: digital-to-analogue (D/A)
• Finish: black; compact form factor for desktop or AV rack placement

How to use

Connect the digital source to the converter using either a coaxial cable or a TOSLINK optical cable, then connect the analogue outputs to your amplifier or powered speakers using RCA cables or a 3.5 mm cable. Power the unit according to the supplied power adapter (if required) and select the corresponding input on your audio source and output device. Ensure the source is set to output digital audio and that sampling rate settings are compatible with the converter (up to 192 kHz).

What to consider before purchase

• Check that your source device has a coaxial or TOSLINK digital output
• Verify that your amplifier or speakers accept RCA or 3.5 mm analogue input
• Confirm that you need up to 192 kHz sampling rate; lower rates are commonly sufficient for many uses
• Ensure you have appropriate cables and a compatible power supply if not included

Usage recommendations

For best results use high-quality digital cables and set your source device to a sampling rate supported by the converter. Position the converter away from large power transformers or strong RF sources to minimize potential interference.
