DigitConvert DAC 192KHz Optical to RCA Audio Converter (Toslink to 3.5mm with Coaxial Cable)
Quick take
This DigitConvert DAC converts optical (Toslink) PCM digital audio into 2-channel analog output for RCA (L/R) and a 3.5mm jack. It’s best for simpler setups like getting TV or console audio into an older stereo receiver or an auxiliary input. The main caveat is format support: it’s PCM-only, so Dolby 5.1 audio won’t work as expected.
Pros and cons
Pros
- Turns optical PCM into analog 2-channel output via RCA and 3.5mm simultaneously.
- Supports multiple sample rates (32, 44.1, 48, 96, 192 kHz) and 24-bit SPDIF PCM input.
- Compact, metal housing aimed at stable performance, with included optical cable and USB power cable.
- Simple operation, and many users report it improves clarity when PCM is configured correctly.
Cons
- PCM-only input, it does not support Dolby 5.1, so you may need to change your source’s audio output settings.
- Some buyers report audio dropouts or buzzing that can be mitigated by reseating the connection, suggesting setup sensitivity.
- Volume control may require managing two remotes depending on your source and receiver arrangement.
What buyers think
Buyer-review evidence points to two themes that matter for real-world buying decisions: compatibility and connection setup. Several buyers describe the converter as an easy way to route a TV’s optical audio into older stereo equipment, especially when the TV output is set to PCM and the optical connection is seated properly. A recurring practical theme is that small connection details can affect whether audio works at all, including optical port readiness and cable handling. At the same time, there is limited but present feedback about intermittent buzzing or no-audio behavior over time, with troubleshooting often involving unplugging and reconnecting.
Overall, the pattern suggests the product can deliver noticeable audio improvement for the right source format and a stable wiring setup, but reliability and noise sensitivity may depend on careful configuration.
Who this DAC is for
Choose this DigitConvert DAC if you need a straightforward way to take optical digital audio and feed analog inputs on older or simpler audio gear. It is a good fit for:
- TV owners using optical (Toslink) output to drive a stereo receiver or powered speakers.
- PS3/PS4, Blu-ray, and HD DVD use cases where your source can output PCM over optical.
- Anyone who wants 2-channel analog (RCA L/R and/or 3.5mm) for music and dialogue, not surround sound.
What it actually outputs (and what it does not)
This converter is designed for digital-to-analog conversion of PCM audio. On the analog side, it provides 2-channel output through RCA (L/R) and also a 3.5mm jack option. On the digital side, it accepts optical input with supported PCM sample rates up to 192 kHz.
It does not support converting to surround formats like 5.1 Dolby. If your source is set to output Dolby (or another non-PCM mode), you should expect missing audio or artifacts, and you will likely need to switch the source’s audio setting to PCM.
Setup considerations that affect results
1) Make sure your TV or console is sending PCM
If your audio source is not set to PCM, expect issues like no sound or noise. For many TVs and streaming boxes, this is a menu setting under digital audio output format.
2) Power matters, especially with USB
The converter runs on 5V DC and uses a USB power cable in the box. Some users and troubleshooting guidance emphasize avoiding unstable power sources (like certain TV USB ports) and using a dependable 5V adapter when needed.
3) Optical cable handling can be the difference between success and silence
Light-touch steps like ensuring the optical plug is fully seated and any protective sleeves or end caps are removed can be important. If you ever get “works sometimes” behavior, reseating and re-checking the connection is a common first move.
Pros and cons, in plain terms
Pros you’re likely to notice
- Better routing for older analog gear: It gives you RCA and 3.5mm analog output from optical digital audio.
- Format-aware performance: It is built around PCM compatibility, which aligns well with many TV digital audio settings.
- Simple, compact design: Small footprint and included cabling can make it easy to install behind a TV or near a receiver.
Tradeoffs to consider
- No surround decoding: It’s meant for 2.1-style output, not 5.1 Dolby.
- Connection sensitivity: Some buyers report intermittent buzzing or no-audio that improves after reconnecting.
- Integration with volume controls: Depending on your system, you may still need to adjust volume using both the source and receiver.

Is it worth it?
This DigitConvert DAC is worth considering if your goal is a budget-friendly way to convert optical PCM into clean 2-channel analog for an older stereo setup. It can be an easy upgrade path for TVs, game consoles, and disc players that support PCM over Toslink.
It is not the best choice if you need Dolby 5.1 from optical, or if your setup is frequently changing (moving cables around, long unstable power runs, or complicated routing) since some buyers report intermittent issues that respond to reconnecting.
FAQ
Will this DAC work with Dolby 5.1 optical audio?
No. It is designed for PCM audio. If your source outputs Dolby 5.1 over optical, switch the source to PCM in its audio settings.
Does it support 192 kHz audio?
Yes. It supports sample rates including 32 kHz, 44.1 kHz, 48 kHz, 96 kHz, and 192 kHz for PCM input.
What analog outputs does it provide?
It outputs 2-channel analog audio to both RCA (L/R) and a 3.5mm jack. These are used for connecting to stereo systems or powered speakers that accept analog inputs.
Does it convert analog back into digital?
No. It is not an analog-to-digital converter. It is meant for digital-to-analog conversion only.
Why is there no sound after setup?
The most common causes are mismatched audio format settings (PCM required) and connection issues (optical cable not fully seated or protective material not removed). Also confirm the unit is receiving proper 5V power.
