Review: Firstly, desertcart screwed up the first time and sent the wrong item - a similar switch from another supplier that cost about a third less, and worked only about a third as well. Sometimes it takes using an inferior product to recognize the incredible value of a quality item. I've used J-Tech products before and have always been impressed by the overall quality of manufacture. The J-Tech 4x2 matrix SPDIF TOSLINK switch might look like similar, less-expensive items, but it's much better built. The housing is very durable and the electronics are well-constructed. In contrast, the other switch had a cheap metal housing and some of the TOSLINK jacks actually physically disappeared inside the device when trying to connect an optical cable to them. Those jacks were evidently soldered directly to a circuit board without any physical support to hold them in place. In contrast, the J-Tech components are solid and reliable in use. In terms of functionality, the J-Tech switch functions very well and it's easy to use. The remote control works well but not at a distance, which is my only complaint. Selection of inputs for each of the two outputs is easy, and I like that they're independent of each other. That way, one can even have the same input connected simultaneously to both outputs if desired. Sound quality is excellent, as would be expected with digital signals. Overall, this is an excellent device. ## Features - 4 Inputs / 2 Outputs for Optical / SPDIF / TOSLink Audio; A True Matrix for Any Input to Any Output: The two outputs share the same input or be from two different inputs. - 4K@120Hz | 8K@60Hz w/ HDR: Experience crystal-clear visuals and fluid motion with 8K@60Hz and 4K@120Hz resolution support.

I have multiple components hooked up to my Sonos soundbar using this switch. **Q: Does the device add any noticeable lag or delay in the sound?** A: No, not as far as I could tell. It's hard to imagine how it could since I think it's just a circuit that gets switched to whatever input you are using. **Q: I have the spdif 4x2 and it does not seem to automatically switch to the input giving signal. i can only manually switch. am i doing something wrong?** A: This unit does not have any automatic input/output switching. However, with the remote you can easily switch inputs and outputs without being in close proximity. **Q: Is the picture shown for the 4x2 correct because the J-Tech website doesn't show a product with this picture. It has a different 4x2 product picture.** A: No the picture is wrong, and in fact is different to the one that was on the product when i purchased.Its White, a bit thicker that that, but shorter length wise. One HDMI in, one HDMI out, One mini USB power in, one 3.5mm audio jack out. Comes with 3.5mm to RCA female cable (L+R) and also USB to mini USB power. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by A***R on 3 February 2021* the unit works flawlessly well made,there is no volume control. ### ⭐⭐⭐⭐⭐ Review *by A***R on 9 February 2019* Firstly, Amazon screwed up the first time and sent the wrong item - a similar switch from another supplier that cost about a third less, and worked only about a third as well.

It's built well, and it's the second J-Tech product I have purchased (the other is an HDMI/Audio Extractor) that simply works...so I now have added J-Tech to a small group of outstanding sellers here at Amazon. The only issue, as stated in other reviews, is that the small remote control has very little range. It must be pointed EXACTLY at the IR receiver on the switcher, and it looks like the range is only about 6' at best. So, keep this in mind if you normally are seated more than 6' away. However, if you plan to or already use a universal remote control that can "learn" from the supplied remote, this completely solves the problem. I have programed a simple Harmony remote (the J-Tech switcher IR codes are in it's data base), as well as a complex URC remote (which easily learned from the supplied remote), and both remotes control the J-Tech switcher from across the room (about 20'). The use of a universal remote brings up a separate issue for me...it's that the switcher only has a "Power Toggle" button (same button turns it on and off). This is typical for this type of product, so I don't hold it against J-Tech. However, if anyone has ever tried to program a universal remote control, you know that any device that does NOT having discrete "Power On" and "Power Off" commands can get out of sync when using macros (press a single button on the remote, and the TV, Receiver, Cable Box, Audio Switcher, etc. all turn on and switch to the appropriate input...press another button and everything turns off). For any product that only has a "power toggle," the only sure-fire solution is to keep that device always turned on. I have asked J-Tech if it's ok to keep the Audio Switcher powered on all the time, and I'm waiting for their reply. The bottom line is that this is a solid device that works as advertised. ## Frequently Bought Together - Portta APET0402TP Premium Quality SPDIF TOSLINK Digital Optical Audio 4x2 Matrix - KabelDirekt TOSLINK – Optical Audio Cable – 35ft – Fiber Optic Cord, S/PDIF Digital Audio Optical Cable for Soundbar, Stereo Systems, Home Cinema, Xbox One/PS4 – Designed in Germany - Amazon Basics Toslink Digital Optical Audio Cable, Multi-Channel, for Audio System, Sound Bar, Home Theatre, Gold-Plated Connectors, 6 Foot, Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.is/products/270274712-j-tech-digital-j-tech-digital-premium-quality-spdif-toslink](https://www.desertcart.is/products/270274712-j-tech-digital-j-tech-digital-premium-quality-spdif-toslink) --- *Product available on Desertcart Iceland* *Store origin: IS* *Last updated: 2026-05-19*
