J-Tech Digital 8x8 HDMI Matrix Switch Switcher HDMI 2.0 HDR 4K@60Hz YUV 4:4:4, HDCP 2.2/1.4, 18Gbps, EDID, IP/Ethernet Control, Compatible with Control4 Driver [JTECH-8x8-H20]

I have a two large stereo speakers outside on the patio and two large stereo speakers inside my room.In order to play the outside, I would have to pull out my receiver & switch the speaker wires from the inside ones to the outside ones. It was a pain in the neck.With this, I just plugged all four speakers into it, then ran two speaker wires to my receiver and BAM! Now, I can push a button and play just the inside speakers or just the outside speakers or even both & I no longer have to pull out anything or switch any wires around!I have had no issues of any sort-no distortion or reduced sound quality, etc.In the future, if I decide to add more speakers to a different location outside or inside, I have room to add four more speakers!

The J-Tech Digital 4-Channel Power Stereo Speaker Selector is a very fine product for what it is. The term "Digital" is misleading since this speaker selector is a simply a set of four switches that allows each of the four speaker pairs to be connected in parallel to each other. There is an optional power resistor that can be added in series (by a switch) with the parallel speaker network to prevent the load impedance from dropping too much as speaker pairs are added to the electrical network. However, the individual components that make up the box are conservatively specified which should make for a very reliable product. There will be no noticeably loss of output audio levels as long as the user does not need to push the audio power amp to its high-end power limits. If this is the case, it might be recommended to use four separate auxiliary audio power amp boxes to drive each of the 4-channels separately.

This worked well with the speakers, but the 12 gauge wiring had to be modified down to 14 gauge as the springs kept popping off

Great product.....everything worked as it should when I connected my four speakers that were powered by my Pyle Amp that had only one set of speaker output terminals. No loss of power whatsoever. My garage never sounded so good. At this price its a steal. Lastly, I had no problems at all with the connectors as some reviewers have stated. I used metal pin connectors crimped to my 16 gauge wire. They held very well. All in all....a great purchase.

When you spend almost a grand for a 8x8 switch you kind of expect a few things like . . .- Documentation that matches your product. Seems stupid not to be able to find the web login and password and then have to call in for it.- A serial port that you can set to something other than 115,200. That rate is not supported in some legacy equipment like older Global Cache Units.- Alternatively an API to use to make the switching calls.- commands that are not translated well into English. If I want the same input showing on all outputs (via the serial) the command actually sets 1 to 1, 2 to 2, etc.- since EDID is noted it would be nice to block a user to trying to send a 4k60z feed down to a 1080p,- only supports 3 EDID values.It is a decent unit, just not well positioned and documented.

I have 3 sets of Stereo Speakers, My back yard, the sun room and the family room. With the simple flip of a switch I have great sound in one two or all three areas. The connections were clearly labeled which made it easy to install. The ability to match speaker impedance based on the number of speakers selected prevents the Stereo system from overloading. I would highly recommend this Speaker Selector Switch.

Excellent audio quality with full metal casing and pinch connectors. Does not require batteries or ac power. Much better than the screw connectors which come loose. Nice heavy unit which allows for 4 sets of speakers to be split off a single wired pair input. Speaker pairs 1-4, can be selected individually or all together. A great unit for a very economic price. This unit is not comparable with the Realistic Radio Shack version which is plastic with screw type connectors which come loose. I've owned both units and highly recommend the J-Tech Digital unit.

EASY TO BREAK WIRING CONNECTORS ON BACK!!! I broke several of the connectors because I kept trying to help the spring loaded squeeze connectors to close after inserting wire. I was going to give this a one star review and throw the unit in the garbage but J-Tech was very courteous on the phone and shipped me a new unit right away which I received in two days! The reason I gave it another shot was that the unit passes audio beautifully to my new Polk speaker sets via my Niles volume controls. I CAREFULLY WIRED THE REPLACEMENT UNIT MAKING SURE NOT TO HELP THE SPRING LOADED CONNECTORS (which hold the wire fine without any help) AND IT WORKS GREAT!

The unit is working as expected, delivery was fast.
