    What is the difference between a $17 and a $150 HDMI cable?

    Yes, source circuits in players differ, and so in a marginal situation you'll certainly find that some will get through where others won't. An installer really should not be putting a hard kink in a cable--that can do bad things in terms of impedance and return loss--but in most cases you'll be...

    What is the difference between a $17 and a $150 HDMI cable?

    Kurt here--hey, just to let you all know: if you've got HDMI cable questions, we're happy to answer them. We pride ourselves in not answering these in a way calculated to make a sale, but just being straight with people. On the subject of cheap-versus-expensive in HDMI cable: the most...

    testing DIY cables

    Ach! That's what I get for not reading closely....yes, of course one should get a 75 ohm resistance reading on those terminators.

    testing DIY cables

    Actually, with a VOM you shouldn't get 75 ohms on anything. The "75 ohms" in "75 ohm cable" or "75 ohm connector" isn't resistance; it's characteristic impedance, which you can't measure with a VOM. You should simply be testing for continuity of center conductor and shield, and non-shorting of...

    DIY cable problem - canare die/parts express crimp frame

    Two things come to mind. (1) Could you be losing some strands from the center conductor when you strip the cable? If the blades are set too deep, you can "shave" some outer strands, which will diminish the diameter of what remains, and if that gets too small, the pin won't crimp on tight...

    Does this S-video adapter exist?

    Actually, I think that's not really an s-video to component video converter; I believe some of the Infocus projectors output component video on a 7-pin mini-DIN plug and use this adapter to break it out to three RCAs. There are transcoders that'll do this, of course, but they're costly...

    Component to RGB?

    If that's all it says about that input in the manual, then it won't take a component video signal; as it indicates, it's set up for RGBHV, which is typical for a 15-pin plug, so you're right--a 15-pin to 3 RCA cable isn't going to do it for you. Your best bet would be to use a switch to allow...

    Idiot subcontractor cut my in-wall SPDIF!! PLEASE HELP ME!

    Ach! Contractors! You know, one of the most common mishaps we run into is the fella who says to the contractor, "hey, I'll need to run a/v cable, so put some conduit in from here to there"...and the contractor runs 3/4 inch conduit...into which are supposed to go an HDMI cable, a couple of...

    Component to RGB?

    Generally, if there's an input labeled "RGB," it's not going to accept component (Y/Pb/Pr) video unless the manual specifically references that it will. You'd want to see something that indicates that that specific input is able to accept it, and how that information would appear in the manual...

    I want to support our sponsors! (in-wall speaker wire)

    All of our Belden speaker wire is in-wall rated, actually. The only one we carry that isn't in-wall rated is the Canare 4S11. If you need more detail on what these ratings mean, there's an article on our site: In-wall speaker cable ratings Kurt Blue Jeans Cable

    Multi channel interconnects.

    One note on that... The Canare RCA plugs are really pretty grippy. We have found that most of the reports of them being too loose turn out to involve people not quite getting them on all the way. It seems that people sometimes mistake the initial resistance of the spring contacts during...

    upgrade component and s-video with BNC?

    There's a small theoretical advantage because you'll get a better impedance match with the BNCs than with s-video or RCA type connectors--but really, the length of the impedance mismatch is so short that it's very unlikely to matter in any perceptible way. I love BNCs--but I sure wouldn't want...

    Difference between coaxial/composite cables

    For unbalanced analog audio, impedance, as such, doesn't really matter. Most of the time in unbalanced audio circuitry the input and output impedances aren't even matched, and a lot of devices are outputting low impedance into high impedance inputs; there's actually a saying about this, which is...

    How to? DVI to YCrCb

    Unfortunately, there's really no way to do that--none, anyhow, that are remotely cost-effective. ATI does make a lot of cards that provide component video out, and you could use one of those to make this connection.

    Looking For Thinner, Flexible Interconnects and Component Video Cables

    How would Belden 7787A be? It's a three-cable bundle of 1855A, which is a really nice mini-coax. We actually have that on hand, and have been about to introduce it on our site, but haven't had a chance to take photos of it yet. Outer jacket diameter is .432 inch, so it's not the big, thick...
