J-Tech Digital SPDIF TOSLINK Optical Audio Matrix Switch 4x2 Digital Audio Switcher 4 Inputs 2 Outputs [JTD-SM0402]

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. 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.

This is definitely the best SPDIF switch (with 4 inputs) I've owned. Everything worked well upon the initial hookup. The remote is very responsive and fast. Plus you get a 2nd output matrix if needed. Thank you J-Tech

This little Optical Audio Switcher (I have the 4x2 model) is excellent. 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.

I had been using another brand 4-port SPDIF Toslink switcher with remote to switch optical outputs from TVs and computers to an Avantree Orbit BT transmitter for output to my Bose noise cancelling BT headphones. Those switchers didn't perform or hold up very well, so I got this one. The J-Tech unit has better sound quality and is a better more solid build. IR remote works really well. Recommend.

I'm using this with two sources, digital audio out from a TV and digital audio extracted from an AppleTV 4K, and two outputs, a DAC and a wireless headphone. Both outputs are active simultaneously and can be used with the same or different sources. The remote works well and includes a power button and 4 source buttons for each of the two outputs. With 96 kHz 24 bit lossless format audio from the AppleTV 4K, I can't hear a difference between connection through the splitter or direct. This is a high quality device at a good price.

Needed a optical audio switch. This item fits the bill perfectly. I originally purchased the JTech splitter, knowing that did not have an 'on/ off' switch...then 'discovered' ( shame on me for lack of in depth research of JTech options) this 4x2 Matrix. I now have it set up today: input from my 11 year old Sony, via optical cable to the Matrix, to Output A, my ZVox sound base, and Output B, to my Yamaha receiver. Read the instructions. The diagrams aid in the set up, and all went very smooth. The only unresolved issue is getting IR code to program my Spectrum Cable remote, so I don't have to use the JTech. All of the JTech IR codes are 4 digits, while Spectrum Cable remote, and all other components use a 3 digit code. After numerous attempts...using 4 digits...3 digits...no success. Hopefully tech support or another reviewer has solved this and can help. If not, will either manually turn it on/off or use the JTech remote. Other than this small issue, it's a great solution for me.

I was looking for an optical audio splitter/switch for a while and finally came across this product. Basically I have 3 output devices (Xbox One, Xbox 360, PC) and two input devices (surround sound system and wireless headsets), but the problem is that the input devices only have one optical input each. This little thing came to the rescue, now I have all three plugged into this matrix, and I can switch between inputs/outputs at the touch of a button on the matrix itself or on the remote controller it comes with. You can plug up to 4 input devices into this, and switch between two output devices. When they says "Premium Quality" they really mean it, it is made of a metal casing and it certainly feels hefty and premium. Sound quality is still amazing out of both my sound system and the headsets, I have not noticed any loss of quality. The only minor gripe I have is that the red and green lights that show which inputs/outputs are active are extremely bright, they can be distracting. But this is nothing major, just a tiny thing they could fix in future versions of this product by using smaller LEDs. Overall, its an excellent product and I highly recommend it.

The unit seems to work just fine. Easy to install and use. 4 stars is because the remote couldn't be any cheaper and still work.. flimsy as can be. Just aware if you buy it. Remote can be easily broken.

the unit works flawlessly well made,there is no volume control.

I was looking for a way to feed multiple toslink inputs into my receiver as one mixed signal. This product indicated that it was a "true matrix", i.e. capable of feeding any input to any output. It failed to mention that it acted only as a spliter, with no mixing capacity. If you're looking for a versatile spliter with a a ir remote this product will be perfect for you. It has excellent build quality, no noticeable sound degradation, and a handy LED indicators for active channels.

Well made product, nevertheless, the remote didn't work in my case. I was using the product to connect audio from my various devices, e.g., TV to my Bose soundbar and my hearing aid streamer. In my case, I need a reliable remote to switch between audio inputs without having to walk over to the unit to manually change input or turn the unit off/on. A reliable working remote is what was missing in my case.
