I have the KanaaN 4K UltraHD HDMI 4x2 Matrix Switch | Remote Control | Audio output: 5.1 Surround SPDIF optical / stereo 3.5mm jack | ARC | MHL port for streaming from mobile | FullHD, UHD, 4K, 4K * 2K compatible | HDMI 1.4 standard of the Company Leicke free obtain for testing. This HDMI switch came well packaged in a smart box with me. Included in the delivery was the KanaaN 4x2 4K UHD Switch, an associated 5 V power supply, an infrared remote control, MHL Cable for smartphones, tablets, cameras with Mirco USB slot and an instruction manual, which is only available in English and Japanese. But this is not a problem because, as you can download the German Manual on leicke.de. The HDMI switch has dimensions of 23.8 cm x 15.8 cm x 6.2 cm and weighs 699 grams straight times. The splitter is finished in black with gold lettering, I do not like the design so much but it must indeed be useful and not just look smart. I assume that it consists of Alumium which is good as this can not be so hot. The remote control is made of plastic and you can use it to control everything from your couch. So now to the terminals, it has an MHL / HDMI connection even where that is connected Smarthphone / Tablet incidentally loaded plus a total of 3 HDMI inputs and of course, he still has 2 HDMI outputs (channel A and channel B). Add to that a headphone output and a SPDIF (audio input). Very many LEDs are red, blue and green, which indicates the condition of each HDMI connections in the colors on the front. This was at the beginning a bit confusing for me but over time you get used to it. Front is also the power button, switch on the HDMI output channels A and B, ARC (Audio output), optical audio output and the audio button. I have connected on the basis of which the on my TV is not enough HDMI inputs are available, and the reposition can be really annoying. My devices: DVD player, PC, TV, SMARTHPHONE / Tablet, sky reciever, home theater system and PlayStation 4. The switch makes it possible one of up to four HDMI input sources simultaneously to two output devices ausgzugeben.Ich have switched the unit and off we went , I really have to say the image quality suffers not a bit under the use of the splitter, which is sometimes the case, but here you do not. The switches of the input channels to 2 output devices work fine if you change the device's display is briefly interrupted to display with new setting again, the whole takes about 2-5 seconds. Playback with 3D works fine. The device has also a built-in CEC support, which means that all devices with CEC vote on one another in an on and off. I am very pleased with the KanaaN 4K UltraHD HDMI 4x2 Matrix Switch as it works even in my sky reciver where do many other issues. The price of 99, I like to give out for as a good device.
