AUTOUTLET 192kHz DAC Digital to Analog Audio Converter 7ft/2.1m (Optical to RCA)
Quick take
This AUTOUTLET optical-to-RCA DAC converter is designed to take digital audio from a TV, set-top box, DVD/Blu-ray player, or compatible game console and output standard stereo (red/white) analog sound to an RCA receiver, powered speakers, or head units. It supports PCM audio up to 192kHz and powers via USB for an easy hookup, but you must set the source device to PCM/LPCM and it will not decode Dolby Digital, DTS, AC3, or 5.1 surround.
Pros and cons
Pros
- Optical (Toslink/SPDIF) input to 2-channel RCA output, useful for stereo-only audio setups.
- PCM/LPCM support up to 192kHz with 24-bit audio stream support.
- USB-powered, no drivers required for setup.
- Includes a 7ft/2.1m RCA cable for flexible placement.
Cons
- Not a surround-sound decoder, so Dolby Digital, DTS, AC3, and 5.1 decoding are not supported.
- TV remote volume control is not supported, so volume may need to be controlled on the speakers/amp.
- Only converts optical to RCA, not RCA to optical or HDMI ARC.
- Buyer-review evidence is limited to short snippet themes, so performance expectations should be aligned to PCM stereo use.
What buyers think
Buyer feedback is generally focused on whether the converter successfully bridges optical output from newer TVs or streaming devices to older RCA stereo systems. Across the available snippets, the most consistent themes are simple setup, no noticeable noise issues in typical use (for example, no static or humming mentioned), and compatibility with a range of source devices (smart TVs, Roku TVs, and older equipment). Some buyers also specifically call out that it works for their stereo RCA chain and can bring back audio functionality in setups that previously lacked optical support. Because the review evidence provided is limited to brief comments, there is not enough detail to reliably judge long-term durability or edge-case compatibility beyond the PCM stereo use case.
Who this is best for
This converter is a good fit when you have digital audio out (optical/Toslink or SPDIF) but your playback gear only accepts analog RCA (L/R). It is especially practical for:
- TV audio setups where your amplifier, receiver, powered speakers, or RV/home audio head unit only has red/white inputs.
- Older stereo systems you want to keep using with newer TVs and streaming boxes.
- Rooms where you want a compact, USB-powered optical-to-analog bridge with a cable that reaches comfortably.
- Buyers who can set their TV/source digital output mode to PCM or LPCM.
Key features that matter in daily use
PCM-to-RCA stereo conversion (not surround decoding)
The unit is built for PCM output (including LPCM) from optical audio sources. If your TV or console outputs Dolby Digital, DTS, AC3, or a surround bitstream, the converter is not intended to decode it into multi-channel audio. For best results, plan on using PCM/LPCM on the source device so you get clean 2-channel stereo sound into your RCA system.
Supported sample rates and audio format
It supports sample rates listed up to 192kHz and handles 24-bit audio streams. In practical terms, that means it is aimed at straightforward “digital in, analog stereo out” use, rather than being marketed as a surround or HDMI ARC solution.
USB power and cable convenience
The converter is designed to run from USB power and does not require driver installation. A built-in 7ft/2.1m RCA male cable simplifies placement, which can be helpful when your TV or console is mounted and your amp/speakers are across the room.
Pros and cons in plain terms
Pros you can count on
- If your source can output PCM/LPCM over optical, you should be able to feed RCA stereo inputs without extra configuration hardware.
- Setup is typically straightforward because of the USB-powered design and the direct optical-to-RCA job.
- Review snippets point to “plug and play” style compatibility across multiple common TV and media device types.
Tradeoffs to consider
- If your goal is surround sound decoding (Dolby/DTS/AC3 or 5.1), this is the wrong category fit. You will want a different type of audio extractor/decoder designed for that.
- Because remote volume control is not supported, you may need to adjust volume on your amplifier or powered speakers rather than only from the TV remote.
- It is not a two-way converter and does not handle HDMI ARC or headphone connections.
Setup checklist to avoid common problems
- Confirm the connection type: use optical/Toslink (SPDIF) from your TV or source into the converter.
- Set the source to PCM/LPCM: switch your TV or playback device digital audio output mode to PCM or LPCM.
- Use the RCA inputs: connect the converter’s red/white output to the analog RCA L/R inputs on your amp, receiver, or powered speakers.
- Plan for volume control: expect volume to be managed on the speaker/amp side, since TV remote volume control is not supported.
Is it worth it?
If you have optical audio out from a TV/console and you need analog RCA stereo input compatibility, the AUTOUTLET converter is a practical, budget-friendly way to bridge that gap. It is most worth buying for PCM/LPCM stereo use cases, particularly when you want an easy USB-powered setup and longer cable reach. It is not worth it if you specifically need Dolby/DTS/AC3 or 5.1 decoding, want HDMI ARC support, or need two-way conversion (RCA to optical).
Alternatives to consider
Without named competitors, the best comparison is by feature fit. Consider another option if your priorities differ:
- If you need surround decoding: look for an optical-to-analog solution that explicitly supports Dolby Digital/DTS/AC3 decoding into the format you need.
- If you need HDMI ARC/eARC: choose an HDMI ARC audio extractor/decoder instead of an optical-to-RCA DAC.
- If you need RCA to optical: choose a bidirectional adapter or a dedicated RCA-to-optical converter.

FAQs
1. What devices can I connect to this optical-to-RCA converter?
It’s meant for sources that provide optical/Toslink or SPDIF digital audio, such as HDTVs, set-top boxes, DVD/Blu-ray players, and compatible game consoles. Your target device on the other end should have RCA (red/white) analog stereo inputs.
2. Does it support Dolby Digital, DTS, or AC3?
No. It does not decode Dolby Digital, DTS, AC3, or 5.1-channel surround. To get the best results, set your source’s digital output to PCM or LPCM.
3. Will TV remote volume control work with this converter?
TV remote volume control is not supported. Plan on controlling volume using your powered speakers or amplifier/receiver.
4. What audio output does it provide?
It outputs 2-channel analog stereo via RCA (L/R).
5. Does it require drivers or external power?
It’s USB-powered and designed to be easy to set up without installing drivers.
