My boss needs an AV receiver which can take 4 component inputs and output to component.

Or alternative, an AV receiver which can take multi source - component, hdmi etc and convert/upscale them to component out or hdmi digital out (not hdmi-a)

And I need one by Wednesday :(
 
personally think you will only ever find one type of hdmi socket on any a/v amp so not sure what you are trying to differentiate :)

not sure you will ever get hdmi > componant without losing a lot of the original signal but most £500+ av amps do multiple sources input to hdmi output (with some kind of upconversion) depends on the display though as to which will be better (sometimes the tv will up convert better than a cheaper amp, sometimes the amp will be better), depending on the specific componants

Just to clarify. It was the stupid cinema man who I sacked last week who told me that the hdmi output of the amp (an Onkyo 608) was incompatible with the input (DVI-D) of the projector. Googling it, he seems to be talking out of his ****

Just for info:

The TWO projectors have component or DVI-D inputs and no hdmi.

The Onkyo 608 has two components in only.

I am trying to connect the following items to the av receiver and then the projectors/sound sytem:

PS3
Wii
Humax Freesat
Blueray

Now all four of the above can be connected via component, however all four can't be connected by hdmi.

The sacked cinema man also said that if I tried to connect multi sources eg a mix of component and hdmi to the Onkyo and then have the amp output via hdmi, that there may be issues in the resolution changing between the inputs and it will mess it up.

Hence his suggestion to get an amp which could hand 4 components in and then output to the projectors via component (with a splitter of course)

Also is it true component > hdmi?

I know quite a lot about AV stuff but this has now gone above my head so excuse my ignorance or any stupid questions/remarks.

Component isn't better than HDMI, theoretically it's worse as it's an analogue format as opposed to HDMI, which is digital but in reality there really isn't any noticeable difference when watching HD. HDMI is more future proof though and can carry much more bandwidth so it can support 3D, ethernet, multiple audio channels and in the future higher resolutions such as 4k.

Don't know much about that amp though so can't really help you there.

DVI-D can be converted to HDMI reasonably easily , you should be able to find simple converters /plugs gooing from one to the other - at worst you can buy a pre-fabricated cable going from DVI-D on the projector to HDMI (out) for the amp

I would also suggest you get two HDMI switchers;

1 switch to choose between either projector (to buy an av amp with two outputs is a serious investment - ie give or take £1k +)

2nd switch to be used for inputs (depending whether its a PS3 AND seperate BR player, and an HDMI humax box similar to what I have, you may not have enough hdmi inputs on the amp)

you might also be able to look at componant /hdmi switchers (ie two componant inputs and two hdmi inputs on the switch and one output for the amp) - then you leave the amp permanantly on the switch input and use that to change source (and not the amp)

This would be very cheap option - and your sacked colleague could well be right about resolution not being great using a switch (but Im not familiar with the freesat box inparticular so I couldnt say)

unless its a freeest HD box it wont be that great through an HD projector anyway

depending on your boss though you could say - for eg - spend £100 - £200 on two good switches and some calbes to try with present amp, if he isnt happy he can still use one switch with a better amp if /when he wants to (rather than spending a fortune on an amp that can directly use two outputs - which is rare in lower spec amps) of course some if not all the cables can also be used

Edit - rarely if ever used componant but I think you have to use a seperate audio channel usually - whereas with hdmi the video and audio signal is combined in one cable

http://www.exceptional-av.co.uk/product.php?fdProductId=392

according to above 608 has 5 hdmi inputs and one hdmi output

so I would definitely get an hdmi switch for the two projectors (and hdmi>>>>dvi cables as mentioned above, by all means speak to a cable company but it shouldnt be hard to locate these, depending on distances between amp and projectors)

two spare componant connections - one for wii and one for humax freesat , I think the 608 should output that direct to hdmi without any issue but you can try and see how much a length of componant cable from the amp direct to the projector would cost as a test

Thanks for that Frank. Going off to do some more research/reading.

Just so you know, the idea is to output to both projectors at the same time. They are NEC 3250W and designed to work together.

The idea being you get 8000 lumens for the cost of under £4k.

In fact you can use 4 daisy chained together to get 16000 lumens.

ANother bonus is that NEC have just finished the 3d software for them and with two projectors plus £80 polarising filter for the lense, you can have 3d which works with the 50p passive glasses like the cinema.

But that's stage 2 project along with adding a NAS (the projectors can control a NAS directly and bring up a list of music/films etc)

I'll take some pics once I have it all up and running. So much for me being the company accountant! I hate the fact that my boss knows that I know far more about technology than him.

Now that we have sacked the cinema man, my next project will be the internal cinema system in the swimming pool which brings it's own problems........

Ever get the feeling a man can have too many tv's? My boss who lives with his two kids will have the following when the swimming pool is finished:

1 x outdoor 7m (275 inch) cinema screen with twin projectors
1 x 110" cinema system with 7.1 surround and hd sky
1 x 90" cinema system with 5.1 surround and hd sky plus ps3 and full racing seats with pedals and wheels
1 x 110" cinema system in the pool with 7.1 surround and ipod dock
1 x40" tv on the balcony in a waterproof enclosure with outdoor speaker system
7 x 40" tv in various rooms in the house

Total spend so far on the cinema systems is £37,000.

Why so many lumens for that size screen? Does 3d really require that much more?

It's outdoors so it needs to be bright enough to be seen early evening and should be bright enough to use on overcast days. Getting four would probable be good enough in sunshine as well.

:eek:

He must LOVE tv!

sorry nothing better to add but that made me go :eek:
 
3D requires mega amounts of light because you lose so much through the glasses etc.

A decent 3D projector that could offer enough light to make the depth of field believable would cost in the region of 10's of thousands. Bit of a double edge sword though, as the average punter would enjoy it, but couldn't afford it, which in turn means the manufacturers cannot get the prices down.
