Hi guys, I've recently bought a new build house and wanted all my rooms networked with Cat 6 cables to distribute HDMI over cat 6. Just thought I'd share my lessons learnt with you. I was shocked to learn that the builder "David Wilson Homes" had never been asked (on our site anyway) to run multiple Cat6 cables to each room, so I was expecting a massive bill as I has 2 * cat6 to the following rooms: Lounge Kitchen Study Bathroom 6 bedrooms So as you can imagine a lot of cabling! I had no idea what the builder was going to charge me for this but was very pleasantly surprised when they came back with £200 for the whole wiring of the cat 6 plus brush plates included all to be located to a central media cupboard. I would definitely recommend getting at least 3 cat 6 cables run as my 4*4 matrix uses 2 so there's no redundancy should one fail or should I want to use a ethernet switch in the rooms. Also if your getting this done, I'm sure it's been mentioned in other threads, but don't get face plates use brush plates so there's no break in the cables! School boy error when getting the builder to install cables for the bathroom tv, I had power for TV from a fused switched spur, my 2 cat 6 cables, speaker cables, and a standard aerial cable. What I'd forgot to run in was the 5v power cable for the receiver for the matrix switcher! This leaves me with only free view in the bathroom for now but I have a plan to either get a 12v to 5v transformer so I can use the TV's 12v power supply or just leave it as is. The tv wall brackets I got off amazon and are an amazing bargain at only £6.99 for the 32" brackets and £7.99 for the 55" and 46" brackets. After a little bit of research I found a 4*4 matrix switch from a company in Durham, it was very reasonable at £459, so my plans are to have 2 of these to make up a 8*8 matrix. Not sure I'm allowed to mention there website but if you want details PM me. Here's a list of my the gear for the complete set up: Lounge: Samsung UE55F8000 Sonos playbar Sonos sub 2 * play 3 speakers Kitchen: Samsung UE46F8000 Media cupboard: Digital climax 4*4 matrix (soon to be joined by another to give 8*8) 2* Sky HD boxes Blue ray player Sonos bridge Bt infinity router Bathroom: 19" videospa waterproof TV 2*Roof mounted speakers 6 bedrooms: Panasonic TX-L32E6B Sonos play 3 speakers The setup is working well just need more time to get my 19" rack in media cupboard and another 4*4 matrix to complete Hope you like the photos.
