Digital-to-analog audio converter

This Runsing adapter converts coaxial or Toslink digital audio signals into analog stereo L/R output for home or professional switching. It accepts sampling rates of 32, 44.1, 48 and 96 KHz with a 24-bit S/PDIF bit stream. The unit provides electromagnetic-noise-free transmission and operates from a 5V DC USB supply consuming 0.5W. A 0.5 m optical cable and 58 cm USB power cable are included.

Replaces direct digital-to-analog connections

Use this converter when a source only offers optical or coaxial output but the amplifier or active speakers require analog RCA inputs. The jump is worthwhile when legacy AV receivers, soundbars or desktop amplifiers lack digital inputs but still deliver the sound quality you want. It also bridges modern TVs or streaming boxes to older hi-fi separates without replacing the amplification chain.

Fits into a compact audio chain

The converter measures 50 x 40 x 26 mm and weighs 90 g, so it sits discreetly behind equipment racks or on a desktop. It needs a free USB port or 5V 1A charger for power and two RCA cables to reach the amplifier. One Toslink and one coaxial input are provided, freeing you to switch between two digital sources without re-patching cables. Operating range is 0–70 °C at 10–85 % RH.

Questions about this item

What connectors does the 50 x 40 x 26 mm converter need on my TV or amplifier?

It requires a Toslink or RCA coaxial digital input on the source and two RCA analogue outputs on the amplifier or active speakers.

How do I power the unit and which step is often missed?

Connect the included 58 cm USB power cable to any 5 V 1 A USB port; the converter will not pass audio until the USB supply is live.

Which supplied cable will need replacing first in a permanent install?

The 0.5 m fibre optical cable is the shortest item in the box and is the most likely to require a longer replacement.
