192 kHz Optical-to-RCA DAC Cable (Toslink to RCA, USB Powered, 2.1m)

Product description

This product is a Toslink (optical) to RCA stereo digital-to-analog converter cable with a built-in DAC and amplifier circuitry. The package provides a single cable assembly with a Toslink plug on the digital input side and two male RCA plugs on the analog output side, and it includes a USB power lead to supply the converter.

The converter supports 24-bit resolution and sampling rates up to 192 kHz. Optical input accepts common sample rates including 32, 44.1, 48, 96 and 192 kHz and decodes 24-bit bitstreams. Internally it uses a dedicated audio amplifier chip and a dual-channel operational amplifier stage to raise the RCA output level and keep the stereo signal clear and low-noise.

Cable length is approximately 7 feet (2.1 meters) from Toslink to RCA, with the converter electronics housed in a molded plastic module powered via a USB connector. Connection is straightforward: plug the Toslink from the TV or source into the converter, run the RCA pair to an amplifier or receiver, and supply USB power from a TV USB port or any 5 V USB source.

Note two important usage details: the unit only outputs two-channel PCM stereo and will not decode 5.1 Dolby AC3 streams — you must set the source’s digital audio output to PCM. Volume adjustments must be made on the connected amplifier or receiver; many TVs will not allow volume control over an optical feed. This device is intended for line-level analog outputs to amplifiers and receivers and is not designed for direct headphone use.

Pros

  • Supports up to 24-bit/192 kHz sampling
  • USB-powered for easy TV connection
  • Built-in DAC and amplifier for clear stereo output

Cons

  • Does not decode 5.1 Dolby/AC3 streams
  • TV remote often cannot control volume over optical
  • Not designed for headphone use

VerdictA simple, budget-friendly solution for feeding modern TVs and media players into older stereo equipment. The integrated DAC and amplifier circuitry deliver clean stereo analog from optical sources up to 192 kHz, and the USB power option makes installation convenient on TVs with rear USB ports. It won’t handle multichannel Dolby streams and doesn’t drive headphones, but for stereo amplification and

Reviews

  1. Adam Moffet 5/5

    Follow the setup notes

    Worked well once I switched the TV’s optical output to PCM. Volume is handled by the receiver; I had to pick a different input on the receiver to get proper sound.

  2. Stefanny Castro 4/5

    Needs USB power

    Connected fine to my TV and receiver; it works but requires a USB power source to run.

  3. Hbrowski 5/5

    Nice for older TVs

    Performs as it should for feeding analog gear from optical sources.

  4. Howard Peterson 5/5

    Good value, performs as expected

    Works exactly as shown. I liked that it uses USB power instead of an AC adapter — many TVs have a USB port on the back. Saved money compared with buying parts separately.

  5. Tartanpion 5/5

    Bridges modern and vintage equipment

    Great alternative to a headphone jack for connecting a modern device to an older amp. Sound quality is much better than a 3.5 mm feed; I used it to attach my TV to an amp without optical input and it worked well.

  6. Keith Renfroe 5/5

    Does the job, no surprises

    No frills, just a straightforward way to get TV audio into my speakers. It performed exactly as I expected.

  7. Pascal C. 5/5

    Worked perfectly

    Did the job perfectly for the price. No hesitation recommended.

  8. SCOTT. S 5/5

    Solved my TV-to-amp chain

    New TVs often lack RCA out, so I used this DAC with an ADC to route optical to my EQ and back to speakers. It delivered clear sound comparable to HDMI ARC once I set formats correctly. Needed the DAC/ADC combo; audio-capture converters wouldn’t have worked.

  9. Lukas R. 5/5

    Perfect fix for legacy sound systems

    Did exactly what it promises. My old 5.1 setup connected to the new TV easily. Installation was plug-and-play and the sound was clean and free of noise. Highly recommended to keep older systems in use.

  10. GEN 5/5

    Usable and reliable

    No problems using it. Satisfied with the sound quality.

  11. Micah 4/5

    Learned a lot adapting vintage gear

    Got my 40‑year‑old stereo running with a modern TV. Optical bypasses the TV volume control, so you must adjust level at the DAC or amp. It converts sound well, though switching the TV off briefly produced a loud static from my speakers a couple of seconds.

  12. Michal1612 3/5

    Meets my expectations

    Did what I expected; decent performance for connecting to older equipment.
