Buying Guide: How To Choose A USB To Optical Converter
What to consider when buying:
- Output direction: If you need to send audio from USB to an optical input, pick a unidirectional USB A to Toslink device (as many options are). If you need two-way audio, verify bidirectional support.
- Sample rates and bit depth: Look for devices supporting at least 48 kHz/24-bit; higher 96 kHz or 192 kHz options provide better fidelity for music and films.
- Device compatibility: Confirm your source device (PC, laptop, PS5/4, or USB DAC) and receiving device (soundbar, DAC, or receiver) are compatible with Toslink.
- Power and drivers: Many adapters are plug-and-play with no external power or drivers. If a unit requires power or software, ensure you can provide it.
- Build and durability: Aluminum enclosures and braided cables generally offer better durability and heat dissipation for long-term use.
- Latency and interference: Optical connections minimize electrical interference. This is especially important for gaming and home theater setups.
- Cable length: Consider whether a 1–2 meter setup suffices, or if longer cables are needed for your desk or entertainment center.
- Additional outputs: Some models add 3.5mm analog outputs. Decide if you need both digital and analog in one device.
