Can switchers be used in both directions? In other words, when the specs say 3 or 4 inputs and one ouput, will it work the other way...as one output switching to 3 or 4 inputs. I ask because I am getting an Onkyo TX-NR708 and it has one HDMI output and one component output. I have 3 separate recorders..2 dvd and one vcr. My thought is to send the one output to the swiitcher and then choose to which recorder I want to use.


Thanks.

Yes that would work fine, that or a video distribution amp and you could record with all devices at the same time. I don't know anything about this amp but it's very inexpensive.

AFAIK HDMI switchers are the only type that cannot be used backwards, that is you cannot use a 4x1 switcher to feed 4 displays from one device, something about handshake issues I believe.

That is very inexpensive. A more complete, but more costly, solution would be this , if you want to avoid the "Y" cables for audio. Radio Shack used to have a very similar item for much less, but I can't find it on their site anymore.

B&H PhotoVideo has several switchers, three made by RF-Link. I just bought the 41i. It has four sets of inputs, each set has R/L audio, S-Video, and composite video. It also has a remote control. It cost $43. W/O the remote, it is $24. I haven't hooked it up yet.

What I linked to wasn't a switcher, but a distribution amplifier. What jjeff's link goes to is a distribution amplifier also. All outputs are active in an amplifier, where only one is active from a switcher. The OP was talking about a switcher, so your post was probably more on topic.

OK.... here comes one of my questions...


Could someone please explain to me in simple (Rose) language, what the heck you guys are talking about?



What are switchers, a video distribution amp and Y cables? I keep getting confused when I see "Y" on my connections.



How does this all come into play when connecting 2 dvds and one vcr?



Thanks!

Most devices such as cable company converter boxes and DVRs have several video outputs from which to choose but only a single set of white/red audio outputs. In one of my stacks there are two recorders, one set up to record S-Video and the other set up to record composite yellow video, and the TV itself takes up a component video output (blue, green, red). All of these connections require use of white/red audio.


What to do? I use "Y" cables (adapters) to split the Motorola HD cable converter's single white/red audio output pair into several feeds for recorders and the TV itself.


Here are typical "Y" cables:

 This is a Y cable. It is an extremely simple device that allows multiple outputs from a single one. It is no different in concept than the multiple outlets that you use when you have more than two things that need to be plugged into AC wall power at one place. The problem with a Y cable is it has no impedance matching or compensation, so every time you divide the output, you lower the level of the signal. this does not happen with 110V wall power, but it does with most electronic equipment.


A switcher allows a single source to feed several devices, but only one at a time. You would turn on the source, then select the deviceyou want to feed the signal to. It can also be used in reverse, so you can have multiple sources (like a VCR, a DVD recorder, etc) plugged into one side of the switch, and a television input plugged into the other side, so when you select the video input of your TV, you can then select from the box which source you really want to watch.


A distribution amplifier is like a switcher but all outputs are active simultaneously, (like the Y cable) but it has active circuitry to compensate for load and impedance, so the output level of any of the plugs is not changed no matter what or how many other items are plugged into it.


Naturally, the Y cable is very cheap, the switcher is more expensive, and the distribution amplifier is more expensive yet. The amplifier almost always has its own power supply and needs to be plugged in to work.

The original poster is actually looking for what is commonly called a routing switcher. The ability to send the output of a specific device (where there are several different output sources connected) to another targeted device or devices (in this case one or more DVD recorders) and are multi-directional. These are more complex (and expensive) than single direction switchers.

Hey Rose, another way you can use a switcher would be if you have limited number of INPUTs on the tv)... Just got a 2-way and a 3-way HDMI switcher - not sure which I'll use, but rather than piggyback two magnovox recorders, as they are now configured -- with one connected to the tv, and the other connected to the L1 input of the first recorder(so you have to have both on in order to watch stuff recorded on the second machine...) I will use the switcher to connect both recorder HDMI outs to ONE hdmi input on the tv, and then (I hope!) the signal from whichever maggie is on at any particular time should be the one showing up on that input. It's supposed to auto-switch. We'll see...


Plan B is to use one of these gizmos for an only occasionally used DVD/VHS recorder and one of the recorders, so I can have both connected to one input and the overlap is less likely to confuse it. That's the way these usually work -- the poster here was asking if you can use them in the opposite direction

Gentlemen, I cannot believe I am writing this...but, I found all of your explanations interesting! Oh no!!!
Am I becoming a student tech geek???



Seriously, I could read and understand what you were teaching me. I like to learn about these things, so I know there are other alternatives available. My problem is in remembering the details because I am learning from square one and there's alot of info to learn from your accumulated years of experience. I, Thank You, for taking your time to teach me... as I did not know about the existence of any of these items. This was very useful information. I also appreciate that you all contribute various examples of how and where I would use these items, along with how you are using them. Now I am beginning to better understand when viewing stacks of various devices....HOW you are able to connect so many.

Artwire.... I will be curious to learn if your Plan A worked. Thanks for sharing!


JeffWld... thank you for alerting me to the fact that there are more than one type of switchers to use. Small details as that, I am sure you all take for granted...where someone in my capacity would never know that.

Church AV Guy... the distribution amplifier- that is just plugged into a regular wall socket? I am not sure I have yet processed how that works...as a Y cable you would plug that into the back of your TV? But, that's OK... one day at a time.


DigaDo...Your photos are always so helpful! Is there anything that you don't have a photo of? Every question I ask, you have a photo to help me understand better. They are always appreciated.

Rose, since you are a PIP user, like me, I'll mention that I just bought a S-Video switcher, so I can use the second S-Video out from each of my DVDRs to go to it, then to the PIP on my TV, a 2007 56" Samsung DLP. I can watch the news on the main picture, and select either DVDR for the PIP, and edit recordings, while watching the news! Yeah, I know your Samsung won't take S-Video, so you can't use it for your PIP. Sorry.


That distribution amp probably has a small transformer/power supply that plugs into it, and the wall.

This is correct. The active circuitry requires external power. Usually this is in the form of a "wall wart" that then plugs into the amplifier.


Wall Wart: A blocky transformer that plugs into a 110V wall plug and is usually so large it covers two or more plugs.

You know for the life of me, I cannot understand for the amount of money I paid for that TV, why Samsung would omit a S-Video connection??!!??? I still have not tried any of the PIP connections you gave me. I ran into a small snag... would only happen to me!
I purchased a new Audio Rack, only to learn that Samsung placed all the connections to the extreme right on the back of the TV. Well, my Christmas Tree is to the RIGHT of my TV. The Audio Rack is to the left. So, instead of stretching wires and resetting everything up again, I will probably just wait till January. I really miss my PIP!!!

WRONG!



Wrong Wrong Wrong Wrong Wrong


I have had the same problem, more than once, in the past. It is NOT something that would only happen to you!

I too felt very stupid when I found the connectors on the "wrong" ends of the components. After stacking stuff up, and arranging components for an hour, to find a half dozen cables that were like, three inches too short (because of connector placement) is infuriating. I didn't want to add a 1 foot extension on six cables, but what other option was there? I pulled it all down and re-arranged it so the cables fit.


No, you are hardly alone in this. Most won't admit it though.

I liked my first flat screen tv so about six months later I bought a second slightly larger one for the bedroom. Same brand, but it ended up being the "upgraded " model ... Now, I'm not so sure. Remote has channel button and volume on the opposite side from where the first one had it ( so invariably I hit channel by accident when I want to change volume) ... And (wait for it) the side inputs and rear inputs are on the opposite side from where they are on the first one. The far side. All my cables were too short... And there was no other way to arrange peripherals. I did manage to swap some cables from the other tv to tide me over, but ended up buying some 10 foot vs. Six ft hdmi so it would more comfortably reach the extra distance. Tried out a new computer and discovered something equally annoying... They moved all the ports to the left side of the laptop so if you need to connect USB or FireWire ... Even a mouse or trackpad ... It has to plug in on the wrong (leftie's revenge?) side. Cord not long enough so extenders required! You are definitely not alone!


Too busy to set up switch test but will let you know if it works.

Luke and artwire,


I love and appreciate your stories!!
Is it just me or are the cord lenghths on all the components shorter then what they use to be?


It was stupid of me not to realize that the inputs of the new Samsung would be all to the right side because my other Samsung are all to the right side. Whatever happened to placing the inputs in the middle where it would be more practical on these large screen TV's????

Maybe others will come forth and share some of their stories, so we can all feel foolish together!




artwire,

Did you notice any type of degradation when you went to a 10 foot hdmi?

I have read that you should use shorter hdmi's because the longer cables will effect the quality of your picture.
