Neoteck 192kHz DAC Converter 7ft/2.1m Optical to RCA Cable SPDIF to RCA Digital to Analog Converter
Quick take
This Neoteck converter takes a digital optical (TOSLINK/SPDIF) audio signal and turns it into analog RCA stereo for older receivers, TVs, and speaker setups. It is designed for 2-channel PCM output, so the main caveat is that surround formats like 5.1 are not supported, and you may need to change your TV or streaming audio setting from “auto” to “PCM.”
Pros and cons
Pros
- Optical to RCA conversion for connecting digital sources to RCA-only audio gear
- 2-channel PCM output (supports common sample rates up to 192kHz)
- Compact, wall-mountable design with a built-in amplifier chipset for stronger RCA output level
- Simple plug-and-play setup (includes an optical cable, power cable, and manual)
Cons
- Not compatible with 5.1 surround, and you must use PCM mode
- Remote volume control may not work for the analog RCA output (volume is controlled at the TV or your audio system)
- Needs 5V 1A power via an adapter (no power plug is included)
What buyers think
Buyer-review evidence is limited in detail, but the recurring themes that show up are consistent with the product’s design. Many buyers highlight that it is easy to set up and works as intended for restoring stereo output when switching to streaming or using newer devices with older RCA receivers. Overall, the feedback supports that this is a straightforward optical-to-RCA bridge for stereo systems, with compatibility depending heavily on setting your source to PCM.
What this DAC converter does (and what it does not)
The Neoteck 192kHz optical to RCA converter is built for a common home-audio fix: bringing digital audio from an optical output (like a TV, set-top box, Blu-ray player, or game console) into an older receiver, amp, or speaker system that only has RCA analog inputs.
It outputs a 2-channel signal in PCM format. That means it is a practical match for stereo setups, but it is not meant to decode or pass through multichannel surround audio. If you expect 5.1, you will need a different solution that supports surround decoding or a receiver with the right digital inputs.
Key specifications that affect buying decisions
- Input and output: Optical (TOSLINK/SPDIF) to RCA analog audio
- Channels: 2 channels (stereo)
- Output mode: PCM
- Supported sample rates: up to 192kHz (also supports 32, 44.1, 48, 96kHz)
- Power: requires 5V 1A power (included items include a power cable, but not a power plug)
- Form factor: compact and wall-mountable
Compatibility checklist (how to avoid the most common “not working” issue)
Most problems with optical-to-RCA DACs come down to format settings and power. Before you buy, make sure you can set your source to output PCM.
- Set the TV or streaming device to PCM: if your audio output is set to “auto,” switch it to “PCM” to ensure the converter locks onto the correct signal format.
- Plan for power: confirm you have (or are willing to use) a compatible 5V 1A adapter. If the adapter is loose or the power connection is unstable, the unit may appear unavailable.
- Expect stereo behavior: if you are watching content that is natively 5.1, this converter is not designed to reproduce full surround output. You may only get stereo PCM.
Pros and cons for real-world use
Best for
- RCA-only receivers or speaker systems that need an optical input replacement
- Stereo listening setups for TVs, set-top boxes, DVD/Blu-ray players, and game consoles
- People who want a small, wall-mountable converter that is generally straightforward to install
Who should avoid it
- Anyone who needs 5.1 surround output from an optical source
- Buyers expecting full remote volume control over the analog RCA output (this depends on the TV and your audio chain)
- Users who cannot provide a stable 5V 1A power source
Installation experience (what setup usually looks like)
In practical terms, the setup is designed to be minimal: connect the optical cable from your source to the converter, connect the converter’s RCA outputs to your receiver or analog input, then power the unit. The included cable length of 7ft/2.1m is meant to make couch-to-rack or shelf-to-TV installs easier without needing additional extension runs.
Alternatives to consider
If your situation differs from the stereo PCM use case, you may want to compare based on these criteria:
- Need surround (5.1): look for an optical-to-analog converter or solution that supports multichannel surround output, or choose an AVR (receiver) that accepts optical and decodes surround directly.
- Need TV-style volume control: consider approaches that support audio passthrough features or setups where volume control is handled by the receiver side, depending on your TV model.
- Looking for digital-in to digital-in flexibility: if your receiver has optical or coaxial digital inputs, skipping a DAC entirely can simplify the chain.
Verdict
The Neoteck 192kHz optical to RCA DAC converter is a solid pick when you need a reliable stereo bridge from optical audio to RCA analog inputs. It stands out for being compact, simple, and suitable for multiple common sample rates, but the key buying caveat is non-negotiable: you must use PCM and accept that it is not intended for 5.1 surround. If your TV or streaming device can output PCM and your audio system is stereo RCA, it should fit the job well.
FAQs
Is this Neoteck DAC compatible with 5.1 surround sound?
No. It is designed for 2-channel PCM output, so 5.1 is not supported. If you want surround, you will need a different type of audio receiver or converter that handles multichannel formats.
Why isn’t it working when I connect it to my TV or streaming device?
The most common cause is the audio output format setting. If your source is set to “auto,” switch the digital audio output to “PCM.” Also confirm the converter has stable 5V 1A power and that the power connection is secure.
Can I control the volume with my TV remote?
Not necessarily. Since the signal is converted to analog RCA for your receiver, the TV remote typically cannot directly adjust the converter’s analog output volume. Depending on your TV and audio setup, volume may need to be controlled in your TV audio settings or on the receiver itself.
What devices does it work with?
It is meant for devices with an optical (TOSLINK/SPDIF) audio output such as HDTVs, set-top boxes, DVD/Blu-ray players, and game consoles.
Does it include the power plug?
It uses a 5V 1A power adapter, but the package does not include a power plug. You will need a compatible adapter and connect it via the included power cable.
