    In total I reckon I've easily spent around 20+ hours scouring for a switch/hub/splitter/other-pseudonym that does something I consider very basic. Bar a trip to Maplins, I've all but given up and turn to you guys for help...

    Basically, I have 5 devices - DVD,DVR,SAT,VCR(S-VHS) & PS2.

    There are plenty of SCART switches around that will take all of these devices and output to a single SCART port on your telly. HOWEVER, what if you have the choice of two output source - in my case a TV and a Projector (Epson TW10H)?

    Well, I found some devices that seem to be able to do this (Trilogy 1 for example) BUT all of them output to only one SCART RGB whilst the other output is usually the dreaded compostite phono outs (usually designed to go the the VCR).

    If anyone out there is aware of a switch that can take 5 inputs and has 2 outputs and is all SCART RGB, please let me have the make/model. Cheers in advance for any info.


    PS: What does parallel SCART mean?
    PPS: The BT903 from TRITON appears to come close but only takes 3 inputs :(
    PPPS: Although I'm not on a shoestring budget, I'm nowhere near being a videophile either. I'm trying to avoid buying an dedicated amp for example.

    What you need is a video switcher unit, there are plenty around (including the one in your amp!) but you'll have to convert the signal to component RGB or S-video.. Extron make a load of switching units... Scart is a pretty defunct medium of connection these days.

    I had the same problem until yesterday. I went into a local tv installation shop and asked if they had anything that would split a signal for me so I could distribute it to my tv and my projector without using switches or changing plugs. He showed me a small scart splitter that looked like the cheap ones you can get off ebay and told me that it would work in reverse and split one signal into 2. I was rather sceptical of whether it would work at all and what the quality would be like but I was suprised it worked very well. It was only a tenner

    I now have the Joytech AV control center switching all my inputs which then connects to this small box. Then one output from it goes to my tv and the other to my projector and it works very well. I can now watch the same thing on my PJ and tv at the same time. You may need a different switch that would handle more than the four of the Joytech (although you could try daisy chaining stuff) but the small switch should work the same.

    Hope this helps.

    Tried a Scart box that had common outputs, found the brightness dropped significantly when both TV and PJ was plugged in (as anticipated), ended up having to buy a Scart buffer amp :mad:

    Youch - its £600!!!! The projector only cost me £450 (ebay), which lets face it is dirt cheap (though Dixons are doing it for £700). This means its unlikely I'll notice any improvement in quality.

    Having said the above the website you suggested might just have the answer in the form of http://www.progressive-av.co.uk/accessories/scart_da.htm
    It means I'd need this plugged into a regular 5>1 scart adapter. Appears to be a bit pricey for what it is but the DC in would suggest some sort of signal boost.

    I did initially think of this idea, getting a bog standard 5>1 from Argos and then using a 2>1 in reverse - but I wasn't sure of two things:
    1. The possibility for signal degradation seemed quite high.
    2. I wasn't sure whether the 2>1 would work in reverse (same sceptisicm).

    I have found a very expensive 1>2 (£70! - see other post here). So as I write this I;m at the info collecting stage. How does the quality compare to a direct connection?

    Hmmm, this is £20 cheaper, and is the one I ended up with

    http://www.maplin.co.uk/Module.aspx?ModuleNo=37672&TabID=1&source=15&WorldID=&doy=23m1

    Quality is fine, and you're quite right, the 2>1 in reverse don't work (see my earlier post - and you end up buggering up the impendance (twin 75 ohm loads in parallel = 37.5 ohm, signal strength is halved and you risk ringing)

    asgura,

    Try maplin code L63AB. I am using two in the config you require with no problems. The description on the maplin website is a little vague, give me a shout if you want to know more.

    According to the spec, the output is S-Video and/or composite; OP wasn't entirely clear what form of output he wanted, but did mention Scart-RGB.

    Suggest to OP to check the spec carefully, make sure that it is what you're after.

    hello mate, have checked the impact on the signal/quality of my cheap solution and to be honest I can't notice any difference. And I would say I'm quite picky about the picture I get. If only either the TV or the PJ are on then I imagine that the signal can only go down one cable at a time anyway so it's not split, merely routed?

    Give it a go, you may be pleasantly suprised, and at only £4 from ebay what do you have to lose?

    Or.... cover the cost of the postage and take mine. I did go down that avenue, now for composite maybe you'd have no problem, but for RGB and source switching I think you'll have problems (in my case, dull images, secondary display on or off); but if you want a 1->3 all-wired share-box then drop me PM with details.

    Thanks, though I';m under the impression that this device outputs in s-video and phono only, not RGB.

    Update: Also found a 2 port SCART distribution amplifier for £40 at http://www.scancom.plus.com or http://www.lektropacks.co.uk, £30 cheaper than the one I mentioned above from http://www.progressive-av.co.uk.

    So, choices so far:
    1. A 5>1 SCART switch connected to a SCART Distribution amp.
    2. B-Tech BT903 TRITON, only 3 ports (kinda) but I could daisy-chain some of my devices.

    So far option two looks better on value-for-money. I've yet to make a final decision thich I'll post here, but at the moment I'm still on the prowl for 'the mother of all switches'. A 4/5 port version of the BT903 would be spiffy.

    I had exactly the same problem and eventually found the B-Tech Quintro. Can take 4 RGB inputs and send them to two RGB outputs. So I have my DVD, Sky and PS2 outputing to the TV and Projector, RGB throughout. Does exactly what it says on the tin. Even remembers the order you switched things on and switches back to the last used device when you switch the current device off. And it's got a remote.

    http://www.b-tech-int.com/Welcome.html

    I bought mine from QED for £65 though I don't see it on their site anymore. Keene are doing it for £70 though.

    You may need to also get a splitter to sit in front of it to handle two of your devices as you want 5 inputs, though I think it has an S-Video input as well that should be good enough for the video.

    I think you have the Quintro+ BT945 - this initally appeared quire promising when came across it last week (prior to my orignal post). However, I crossed it off the list because it only has 1 RGB output. The other outputs are composite RCA phono and so video signals won't be as good. Is it this model you have and if so how are you getting dual RGB out?

    Addendum: Oooh! This form http://www.b-tech-int.com/UK Newsletter/Best Buy What Video small.jpg
    "There are 5 SCART inputs, 4 of which are RGB/S-VHS capable" so far, so ho-hum, but... "3 of which can ALSO be used as outputs" - Now that bit is interesting and I can't understand why B-Tech don't bother mentioning this on their website...I'm going to be having a closer look...

    Yup that's right, there is one dedicated RGB out but several of the other ports can be used as either inputs or outputs. I for one can't see any difference between using the dedicated and non dedicated outputs. I get a RGB signal to both my TV and projector.

    Like I said you would probably want to combine it with 1 or 2 simple SCART splitters. Getting lots of sources into a few inputs is the easy bit. It's getting more than one output from the same input that is tricky and this unit does that.

    Warning I've since established the following:

    The B-tech BT903 does have dual SCART outs, but only one is RGB capable whereas the other is S-VIDEO / Composite.

    The B-tech BT945 on the other hand 'officially' has one output, but one of the inputs can be configured for output and DOES support RGB.

    Hence both models support 3 in and 2 out (to TV and Projector) but the cheaper option will only output RGB on one socket.

    Bear in mind they are two different devices with different names!

    The BT903 is called the Triton while BT945 is called the Quintro+. It's the Quintro+ that has the ability to have multiple RGB outs.

    B-TECH QUINTRO FIVE WAY SCART SWITCHER BT945

    i can comfrim that this does have two rgb outputs, as i use it to send rgb to my tv and rgb + Composite to my projector in this mode you get 4 inputs and 2 outputs.

    I can also confirm that the B-Tech Quintro+ will take 4 RGB inputs and give 2 RGB outputs. One of the 5 inputs is designed to output RGB but not accept it as an input (as the pins are the same) I have mine feeding my TV and PJ RGB and RGBs respectively with no visible signal loss.

    From http://www.keene.co.uk/cgi-bin/bigcodesearch.pl?BT945 (£70 inc VAT +Del)
    The later model is identifiable by the inputs having numeric labels (1,2, etc) not names (VCR, SAT etc).


    Also available from http://cpc.farnell.com/jsp/endecaSearch/partDetail.jsp?SKU=AV09359&N=401 for £70 all in with next day delivery (as the order is over £30 ex VAT). I can recommend CPC as top quality suppliers but not necessarily AV specialists!

    You'd need to daisy chain one of your sources through the SAT box to gain the extra input you want but I would have thought you'd probably have one of your recorders set like that anyway?

    Does anyone know if the B-Tech Quintro Five Way SCART Switcher (http://www.keene.co.uk/pages/cat/05dup/05F.html) is exactly the same as the Vivanco SBX99SE SCART switchbox (http://www.keene.co.uk/pages/cat/05dup/05F.html)?

    Reason I ask is because a friend of mine needs to plug a few RGB Scart video sources (Sky and DVD mainly) and output them to a projector (RGB Scart -> RGBS) and a CRT TV (RGB Scart). He wants to do this as minimal cost and I can get hold of the Vivanco box cheaper than the B-Tech one.

    Or if someone else can suggest another means of attaching his equipment together so he has 2 RGB Scart inputs and 2 RGB Scart outputs?

    I do have a Joytech AV Control Centre (http://www.play.com/play247.asp?page=title&r=ELEC&title=171036&p=321&g=409&pa=sr) I would like to sell him, but at the moment one of the B-Tech / Vivanco boxes looks like it will work better s they have dual outputs where as the Joytech box doesn't.

    Nick_T - Your Keene links don't work mate.
    All I can say for sure is that the Quintro+ definitely works and I spent a lot of time searching for the right device!

    Sorry these are the proper links:

    Vivanco SBX99SE SCART switchbox (http://www.keene.co.uk/cgi-bin/codesearch.pl?SBX99SE)
    B-Tech Quintro Five Way SCART Switcher (http://www.keene.co.uk/cgi-bin/codesearch.pl?BT945)

    They just both look like near enough the same device so I was wondering if anyone had tried the Vivanco product.

    That would be perfect alongside the Joytech AV Control Center. Can you be certain that it duplicates an RGB Scart signal to both outputs? I doubt my mate would be able to notice any difference in video quality (he used his DVD player on 4:3 Pan&Scan for a whole year until I pointed this out to him and changed it to 16:9 for his Projector and wide screen TV :suicide: ).

    I swear I have seen the same product on the Maplin website, I will have to have a search.

    :thumbsup:
