Home cinema wiring
I'm about to wreck our dining room and it will soon re-emerge as a cosy
living room (estate agents would call it a "family room"). Eventually I'll be installing a home cinema setup, and I'd like to get some fixed wiring in place before decorating. The trouble is I know nothing about home cinema gear so I don't know what sort of wiring I'm going to need. Our TV, which hasn't been switched on in years, is one of those fat heavy glass eyes with a mains plug and an aerial socket. I'm aware that things have moved on since then but I haven't kept up. I'm thinking of a big flat screen in the middle of one wall, speakers in the four corners (how high?), and a collection of black boxes near the screen to make it all work. I have no idea what provision I should make for connecting the boxes to the screen and speakers, other than knowing I don't want wires trailing all over the place. Any advice appreciated. I have little interest in broadcast TV but it would be daft not to have any connection with the outside world. I'll be providing an internet connection for the black boxes and I know how to do that. It's possible that I'll get a satellite dish installed at some stage (there's no prospect of cable) and I assume that the satellite wiring would enter through the outside wall. That's nowhere near where the black boxes will be - so how might I prepare for it? Or would I be wasting my time with satellite when the internet is taking over? The room's about 4 metres square, by the way, with a concrete floor which will be carpeted, and thick stone walls. -- Mike Barnes |

Run several mains style cables (for audio) and a lot of CAT 5 (for anything it might be useful for, like a home network) and coax (to the TV from the loft amplifier/distributor) to wherever you might want to have bits of the setup. SEPARATELY run a mains ring. Now even if you leave the cables coiled up inside a backing box, at least the cables are there if you need them. Its generally no big deal to hack out for another backing box and put a socket next door to one that exists, and ,if there is enough cable, extend a particular service. |

I have no idea what provision I should make for connecting the boxes to the screen and speakers, other than knowing I don't want wires trailing all over the place. Any advice appreciated. IME, you will want a TV with at least 4 HDMI inputs (everything is going HDMI and the cables are fairly thin). So you will want to the TV - probably: 1) Mains 2) several audio cables back to amp 3) ethernet to TV (yes, really - modern TVs can do iPlayer direct - I would not be surprised if some will eventually do Netflix direct too). 4) Aerial to TV 5) HDMI for DVD 6) HDMI to Sky box if required - or BT Ondemand or Virgin box 7) Component or composite video (3-5 cables) to WII or some other games console. Note Games Console may be able to provide Netflix streaming service (my WII can). So the potential for lots of cables is high. A big lump of D-Line trunking looks pretty neat between the TV and the cupboard with the rest of the gear. Then you'll need said cupboard - with a glass front to let the remotes work. Will you build in a cupboard or use a free standing one? Get or make one with lots of shelves, vertical void in the back for cabling and as mentioned, glass doors. And ventilation. I have little interest in broadcast TV but it would be daft not to have any connection with the outside world. I'll be providing an internet connection for the black boxes and I know how to do that. It's possible that I'll get a satellite dish installed at some stage (there's no prospect of cable) and I assume that the satellite wiring would enter through the outside wall. That's nowhere near where the black boxes will be - so how might I prepare for it? Or would I be wasting my time with satellite when the internet is taking over? Satellite will always have 100's of channels - but we are fast moving towards the time when on line streaming will provide anything you want over a 2+Mbit connection. Netflix is already technically pretty good. Their catalogue is weak but to be fair they have only just started with UK streaming and I am seeing stuff being added every day - so it is only a matter of time. The room's about 4 metres square, by the way, with a concrete floor which will be carpeted, and thick stone walls. Given that particular scenario - I would bolt the TV to the middle of the best wall for viewing. Then in the corner I would build a quality (but could be "rustic looking" wooden cabinet to house the kit. The cabinet would have a PDU for mains (you'll need loads of sockets here but not many amps). Heavy bit of D-Line or some suitable trunking[1] across to the TV (direct - or along the skirting area then up). I would allow 4 square inches of cable area in this - seems a lot but it will fill). The cabinet will end up with a load of piles of surplus cable so it would be a good idea to have a 4" deep void behind the shelves with some tie back points for tie wraps or velcro bands. The other solution is to get custom cables. Given you will have to buy HDMI cables for your kit, go to google and locate the best source, Do NOT buy from COMET, Dixons, Curries etc - they will charge you 5-10 times the price. Flat HDMI cable is easier to route and you can buy it to the nearest metre. You could also shorten all mains cables in the cabinet and even put IEC plugs on as IEC PDUs are more compact than 13A. As far as the sat goes, get it taken in at ceiling height and drop it down to the cabinet from the floor void above. You would do well to drop some conduit (20mm round) down to the sit eof the cabinet - perhaps 6 lenghts to 3 double back boxes. This should give you more than enough for mains, aerial, sat, network and mabey speaker cables back up. You didn't say of your stone walls were plastered? My solution is only one of a thousand possibles - it may not suit what you were thinking of - other will have other ideas... -- Tim Watts |

You can, but its not low enough resistance for decent bass. (Cat5 as speaker cable) True enough but not an issue with most domestic home cinema systems where the "sub woofer" also handles the LF from the other five channels via "bass management". This avoids the requirement of trying to place 5 full range (ie large) speaker boxes in the room. As for the OP it's probably easier to buy an AV Amp of some sort to stick in the pile of black boxes and everything goes through that. All the telly needs is a single HDMI and mains. No interest in broadcast telly so there isn't a requirement to get an audio signal back from the telly's reciever(s) to the AV amp. Some hint of DSAT but that would go through the AV Amp... I'd be wary of mounting a TV up on a wall, too easy to get it too high and a crick in the neck watching it. Cabling position really depends on the layout of the room and location of the viewing listening position. Each corner wouldn't really be very good if the listening position screen line is on a diagonal of the room for instance. -- Cheers Dave. |

It's impossible to work all this out without knowing the exact equipment
you'll be buying. All I can suggest if you wish to make provision before doing this is to run in adequate trunking to take all the cables etc when you do decide what to get. -- *It was all so different before everything changed. Dave Plowman London SW To e-mail, change noise into sound. |

You can hide anything behind it then, and get behind it fairly easily (depending on how you build it). Much easier than channelling into stone walls. Cheers, David. |

The room's about 4 metres square, by the way, with a concrete floor which will be carpeted, and thick stone walls. I'm following up my own posting to thank everyone who's responded and clarify a few things. Sorry not to reply individually but there's so much overlapping information that this way makes most sense to me. I know some people like to go to town on their video systems but TBH I can't see that happening here. We don't watch TV at the moment and I can see this system being used for the occasional film on DVD or whatever or so that visitors can get the sports results, but not much else. There's another room for listening to music, with the obligatory monster speakers and cables. So I'm not looking for ultimate quality or something I can upgrade for fun, just something that works and doesn't look too conspicuous. Having said that surround sound would be nice and AFAICS won't be terribly difficult. Regarding the height of the speakers I'm tempted to put them on floor stands with low-level outlets so that the height is adjustable and the stands will mask the leads. I do like the idea of mains cable for the fixed speaker wiring because it's thin (especially if removed from the outer sheath) and it's manageable. The walls are plastered, but unfortunately the plaster is stippled. I wouldn't have chosen it but I can't be arsed to skim it all over so it's staying. I'm therefore looking at speaker wiring behind the skirting boards, or possibly on the floor next to the carpet grippers. But what sort of connectors would you expect to see at each end? I know wire binding posts would be cool but I'd prefer a plug-in connection. Knowing nothing about modern TVs I assumed that the topology would be like a PC, with all the intelligence and connectivity in a table-top box, and a screen that's *just* a screen with only two connections (mains and video). Looking at ads on the internet though, it seems that everything tends to come in one lump and if you want to put your screen on the wall you have to run all the bloody wires up there as well. Have I got that right? As I said I'm looking at a screen location in the centre of a wall. The room is littered with obstacles (two external windows, one internal window, fireplace, central heating radiator) so there isn't a great deal of choice. The location I had in mind is on chimney breast, and yes, the fire will be used. I don't know whether that's a bad idea, heat-wise. The fire is a cast iron wood-burning stove entirely contained within the fire opening (the front of stove is behind the plane of the wall) and the flue is lined so it could be worse I suppose. Looking on the bright side, there's an alcove to the left of the fire, 500mm deep, which would be ideal for the equipment cabinet, which I'd buy if possible or make if I can't find anything suitable. And if the wiring is in a surface conduit I could route it up the side of the chimney breast and sneak it round to the screen quite inconspicuously. I haven't decided on a screen size yet but 60 inches isn't out of the question and would just about fill the 1500mm width of the chimney breast anyway. Height-wise the fireplace containing the stove is only 800mm high so the screen wouldn't have to be particularly high off the floor. At the cinema I like to sit on the front row so I'm used to looking up! If rising hot air is likely to be a problem I might well fit a "decorative" shelf below the screen to deflect it but that wouldn't add too much to the height. The other possible location for the screen is across the corner in the aforementioned alcove but that would limit the screen size and I don't know how the surround sound would work with the screen in one corner and viewers in the opposite corner. Thanks for all the ideas, my thoughts are focusing nicely. Ideally I would spec out the equipment now, but I'm putting that off for as long as possible. One last question: satellite. Is it a simple coax cable like UHF or is there more to it than that? -- Mike Barnes |

If you want to use the TV's receivers they will obviously need their appropiate aerial feeds but if you are going satellite then that box will sit by the AV amp and be fed to the TV via that so you can get the full digital sound from the sat box to the amp, like wise the DVD/BluRay would plug into the AV amp.

There is an active box at the dish (the LNB) this converts the satellite siganl into frequencies that are easier to squirt down coax. It also selects polarisation and band under control of the satellite receiver. This means each satellite tuner needs it's own feed from the LNB. Note "tuner", to allow you to watch one channel and record another you need two feeds. If your TV has a satellite tuner that will also need it's own feed. -- Cheers Dave. |

We haven't touched on the actual telly spec side yet... ... presumably I'd be running all those speaker wires to the amp rather than the TV. Yes to the amp. Very few (if any?) TV's have built in surround amplifiers. You say "active" box at the dish so does it get its power from the tuner by DC across the coax? Yes it's powered from the satellite box. Is satellite a DIY sort of job or should I call in the specialists? Very DIYable the Dish just needs to be able to have a good clear view of the right bit of sky. That is roughly somewhere that is sunlit at about 20 past 11 (or is it 20 past 10?) in the morning. The sun will be quite a bit lower at this time of year and higher midsummer but it gives you a good idea for suitable places. The dish doesn't need to be a chimney height, ours it at about 8' above the ground high enough to be out of the way but low enough to be whacked with a broom handle to knock the ice off it when that stops it working. -- Cheers Dave. |

Leaving it open to interpretation by those who lobbied for it in the first place - like trade bodies. To their greater advantage. CORGI were notorious for this. But it does little to stop the cowboys. -- *Middle age is when it takes longer to rest than to get tired. Dave Plowman London SW To e-mail, change noise into sound. |

All I can suggest if you wish to make provision before doing this is to run in adequate trunking to take all the cables etc when you do decide what to get. Its not that hard for home cinema. The only thing you need on the wall is the screen and the centre speaker. You then use HDMI to connect to an AV amp and some T&E for the speaker and a mains lead. Then you need front speakers either side but probably not close to the screen. There are also rears and possibly side speakers and maybe even high speakers to add elsewhere. The LFE (subwoofer(s)) can go out the way somewhere. You can make it more complicated but I don't see why, the latest AV amps will transcode other video to HDMI so you never need to send composite, component or SCART to the screen. The only other things you may want is Ethernet if you want to use a smart TV as opposed to a smart blueray or a PC and/or an IR repeater if your screen doesn't send commands over its HDMI to control the AV amp, etc. |

The only thing you need on the wall is the screen and the centre speaker. You then use HDMI to connect to an AV amp and some T&E for the speaker and a mains lead. Far too simple. It is generally easier to route all your sources through the TV and then feed to the AV amp. Most displays require the audio to be delayed and a decent TV will do this for you. -- *When blondes have more fun, do they know it? Dave Plowman London SW To e-mail, change noise into sound. |

So will a good AV amp, and there is data in the HDMI data put out by the TV to suggest how much to do it by. In any case the audio wont be coming from the TV, it will be the master audio from the blueray player or the DD from other sources, it need (should!) never go anywhere near the TV. |

I've been encouraged to make up my mind what sort of gear I want, and I think I'll be getting something like this: http://www.trustedreviews.com/panaso...-System_review Plus a big screen of course. I've worked out how to get coax from the roof to the receiver without making a mess, so I'll just leave that for the time being, until a TV signal is wanted (which might be never). -- Mike Barnes |

I'd rather have a decent amp without all that crap. Unless it is only ever used for 'home cinema'. -- *If at first you do succeed, try not to look too astonished.
