AI Verdict
This is a budget 192kHz/24-bit DAC that converts digital optical or coaxial PCM audio to analog L/R RCA and 3.5mm, designed for devices lacking analog outputs.
This PROZOR DAC is a situational fit because it effectively bridges the gap between digital optical/coaxial audio sources and analog RCA/3.5mm inputs, supporting high 192kHz/24-bit PCM audio. However, its strict 2-channel PCM requirement and lack of 5.1 channel support limit its use in more complex home theater systems. The fixed 1.1m RCA cable also dictates placement.
If you need 5.1 channel audio or integrated volume control, look for DACs explicitly stating Dolby AC3/DTS support or featuring a volume knob.

Pros
- Converts 192kHz/24-bit digital audio signals from optical (Toslink) or coaxial inputs to analog L/R RCA and 3.5mm outputs.
- Includes a built-in audio amplifier chip to address low RCA output volume, aiming for pure and crisp sound quality.
- Supports sampling rates from 32kHz up to 192kHz, and 24-bit SPDIF incoming bit streams on both channels.
- Features a compact design with a non-pluggable 1.1m RCA cable, simplifying setup and saving space.
- Plug-and-play operation means no driver installation is needed, making it accessible for non-tech-savvy users.
Cons
- Incompatible with 5.1 channel signals like Dolby AC3; requires source audio output to be set to 2-channel PCM/LPCM.
- The 1.1m built-in RCA cable is non-pluggable, limiting placement flexibility without an extension.
- Requires a 5V 1A USB power supply, which is not included in the package.
- Some users report compatibility issues with streaming services like YouTube or Netflix.
- Lacks a physical volume control knob on the unit itself, requiring volume adjustments via the connected amplifier or speakers.
Dimension Scores
The 192kHz/24-bit sampling rate and built-in amplifier chip aim for pure and crisp sound, with one user reporting 'excellent' sound via the 3.5mm jack.
The built-in audio amplifier chip specifically addresses low RCA output volume, providing extra gain compared to DACs without this feature.
It offers both optical (Toslink) and coaxial digital inputs, along with L/R RCA and 3.5mm analog outputs, but the fixed 1.1m RCA cable and lack of 5.1 channel support are limitations.
Weighing 5.3 ounces with a compact form factor and a built-in cable, it's designed for easy installation and portability, though the non-pluggable cable can be restrictive.
Best For
- Connecting modern TVs or gaming consoles (PS3, PS4) with only digital audio outputs to older stereo systems or soundbars with RCA inputs.
- Users needing to output digital audio to headphones via a 3.5mm jack from a source without one.
- Setting up a basic audio connection for Blu-ray/DVD players to an amplifier that only accepts analog RCA.
Not Recommended For
- Home theater setups requiring 5.1 channel surround sound from Dolby AC3 or DTS sources.
- Users who need a DAC with integrated volume control for direct headphone or speaker adjustment.
- Anyone needing a longer than 1.1m RCA connection without using an extension cable.
Watch Out For
- You MUST set your TV or source device's audio output to PCM/LPCM, otherwise you'll get no sound.
- The device is incompatible with 5.1 channel audio formats like Dolby AC3, so don't expect surround sound.
- You'll need your own 5V 1A USB power adapter; it's not included in the box.
- Some users have experienced compatibility problems specifically with YouTube or Netflix audio.
- The built-in RCA cable is 1.1m and cannot be detached, which might be too short for some setups.

What Buyers Say
Many users highlight the necessity of correctly configuring their source device's audio output to PCM, as failure to do so results in no sound. The built-in amplifier chip seems to effectively boost the analog output volume, which is a common pain point for cheaper DACs. While generally functional for its intended purpose, some users have encountered specific audio dropouts or lack of sound when using streaming apps like Netflix or YouTube, even with PCM enabled. The compact size and included optical cable are frequently mentioned as conveniences.
“Ugh, finally got my PS4 sound to my old stereo, but seriously, why do I have to dig through TV menus just to make this thing work? And no Netflix sound sometimes? Annoying, but it does the job for my games.”
Common Praise
- Effectively converts digital optical/coaxial audio to analog RCA/3.5mm.
- The built-in amplifier chip provides sufficient output volume for RCA connections.
- Easy to install and operate once the source device's audio settings are adjusted.
- Compact and lightweight design makes it easy to place.
- Includes an optical cable in the package, saving an extra purchase.
Common Complaints
- Requires manual setting of source device audio to PCM/LPCM, which can be confusing for some users.
- Does not support 5.1 channel audio formats like Dolby AC3, leading to disappointment for surround sound users.
- No power adapter included, only a USB power cable.
- Reported compatibility issues with audio from YouTube or Netflix on some devices.
- The built-in 1.1m RCA cable is not detachable and can be too short for certain setups.
Ownership Tips
- You'll likely need a spare USB wall adapter to power this, as it's not included.
- Expect to spend a few minutes in your TV's audio settings to switch to PCM output; it's not always intuitive.
- If you experience no sound, double-check that your source is outputting 2-channel PCM, not Dolby Digital or DTS.
- The 1.1m RCA cable is permanently attached, so plan your device placement accordingly or get an RCA extension.
- The unit itself doesn't have a volume knob, so volume control happens at your amplifier or headphones.
Frequently Asked Questions
Does this converter support 5.1 surround sound?
No, this converter is incompatible with 5.1 channel signals like Dolby AC3. You must set your audio source to output 2-channel PCM or LPCM for it to work.
Do I need to install any drivers for this device?
No, the PROZOR converter is plug-and-play and does not require any additional driver installation. Just connect your cables and power it on.
Is a power adapter included with the converter?
No, a 5V 1A USB power adapter is not included. You will need to provide your own, though a USB power cable is supplied.
Can I use this with my TV for Netflix or YouTube?
While generally compatible with HDTVs, some users have reported compatibility issues specifically with YouTube or Netflix audio. Ensure your TV's audio output is set to PCM.
What kind of audio inputs does it accept?
It accepts digital audio signals via one Toslink (optical) input and one RCA (coaxial) input.
Buying Guide
When you're looking at a digital-to-analog audio converter like this, you're essentially trying to get sound from a newer device (like a TV or game console with only optical or coaxial outputs) to an older audio system (like a stereo receiver with only RCA inputs). The main thing to understand is that these converters usually only handle a specific type of digital audio, typically 2-channel PCM. If your source is trying to send out surround sound (like Dolby Digital), this converter won't understand it, and you'll get no sound.
192KHz Sampling Rate
This number tells you how many times per second the analog audio signal is measured and converted into digital data. A higher sampling rate, like 192kHz, means more data points, which can result in a more detailed and accurate sound reproduction, similar to how more pixels in a photo create a clearer image.
24-bit SPDIF Incoming Bit Stream
The 'bit depth' (24-bit here) refers to the dynamic range and resolution of each audio sample. More bits mean a wider range between the quietest and loudest sounds, and finer steps in between, leading to a richer and less 'flat' sound, much like a wider color palette in a painting.
PCM Digital Audio
PCM (Pulse Code Modulation) is the standard, uncompressed digital audio format. This converter specifically works with 2-channel PCM. Think of it like a universal language for audio; if your device speaks a different language (like Dolby Digital 5.1), this converter won't understand it, and you'll need to change your device's settings to speak PCM.
Alternatives
If this converter doesn't fit, search for DACs that explicitly state support for Dolby Digital or DTS if you need surround sound, or look for models with a built-in volume control if direct audio adjustment is important to you.
