Manufacturer description
The Neoteck Optical to RCA Cable DAC Converter solves a problem every retro-audio and console setup eventually hits: a modern TV or Blu-ray player with only a digital optical output, and an amplifier or powered speakers that only speak analog RCA. This SPDIF to RCA converter handles 24-bit/192kHz signals, accepting 32, 44.1, 48, 96 and 192kHz sample rates so your source material passes through without the downsampling that muddies detail. Neoteck builds in a dedicated audio amplifier chip and a dual-channel operational amplifier to lift the RCA output level, which matters when you are…
SpecPicks Verdict
SpecPicks scored Neoteck Optical to RCA Cable DAC Converter using a rating × review-volume × price-fit model applied to published specs and reviews across the audio & midi category. Neoteck's audio & midi lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for audio & midi of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.

Frequently Asked Questions
Will this work with my PS4 and TV optical output?
Yes. Neoteck lists HDTVs, set-top boxes, DVD and Blu-ray players and game consoles including the PS4 as supported sources on the SPDIF optical input.
Why do I get no sound or static from my TV?
The converter does not support 5.1 channel signals such as Dolby AC3. Go into your TV or console audio settings and change the digital output format to PCM.
What sample rates does it support?
Optical input accepts 32, 44.1, 48, 96 and 192kHz sample rates at up to 24-bit, so 24-bit/192kHz sources pass through without being downsampled.
Are the RCA outputs male or female?
This version has female RCA outputs, so you will need male-to-male RCA cables to reach your amplifier. For a male-output version, Neoteck points to ASIN B01MRII0D1.
Can I use it to convert RCA back to optical?
No. Neoteck states the converter does not support RCA to optical. It is one-directional, optical (SPDIF) in to analog RCA out only.
