What this cable does and who it suits

The Cubilux USB A to Toslink optical cable carries digital audio from a computer or a PlayStation 5 or 4 to a DAC, amplifier or AV receiver. On a PC it handles stereo and 5.1 surround sound; on the consoles it is limited to stereo. It is not compatible with TVs, Xbox, Switch, projectors or car USB ports.

Check your devices before ordering

Verify that your source has a standard USB Type A port and that your audio gear accepts a Toslink input. Ensure both ends can run at a matching sample rate — 44.1, 48, 96 or 192 KHz at 16 or 24 bit — otherwise you may hear distortion or silence. On macOS the system volume control will not work; adjust level on the amplifier instead.

Build and everyday use

A nylon-braided jacket and aluminium alloy housings shield the fibre from EMI and RFI while resisting wear. The 6.6 ft length gives flexible placement between desk and rack. Plug-and-play operation needs no driver; simply connect both ends, select the optical output in your sound settings and match the sampling rate on the receiver for stable playback.

Questions about this item

What comes in the box and is anything else needed to use it?

The cable has a USB-A plug on one end and a Toslink connector on the other. No extra adapters or drivers are required; just connect it to a compatible USB-A port and your optical input device.

Which sampling-rate version should I choose for my setup?

The cable handles 44.1, 48, 96 and 192 kHz at 16 or 24 bit. Match the rate in your computer or console audio settings to the rate your DAC or receiver supports for distortion-free playback.

What does 5.1 surround support actually give me on a PC versus a PS5?

On a PC the cable can pass 5.1 surround sound; on PS5 or PS4 it is limited to stereo only. 7.1 surround is not supported on either platform.
