Several XLRs vs none

[sonare]

Reading the thread asking about delays in shorter cables made me wonder what real or imagined side effects there might be with 4 25ft cables vs 1 100ft cable-- (or 8 25s vs 2 100s) if all are the same brand/type and the XLRs are good quality (Neutrik or equiv).

If I weren't so lazy I would do it and report, but perhaps its already been done....

I would imagine that there would be some degradation of the signal. Every time there is a connector, I think there would be a slight impedance change since you are going from copper to nickel and then back again.

Possible, but can you hear it? I've had to patch into some of the crudiest stage boxes and gotten great results through a few hundred feet of cable, though my sensabilities said "no way". This whole dialogue reminds me of the Biblical proverb of "straining the gnat, but letting the camel through". Use the best connections possible, but there are far more worrisome issues than cable length or connectors, unless you're comparing 5ft. to 5Kft., corroded to clean connectors, etc.

[Jim vanBergen]

just as there is a tiny change in capacitance and frequency response, yes- but we are talking hundred-thousands of a second, picofarads, and thousands of a decibel.

[bishopthomas]

With that many point of failure I would be more worries about losing signal completely before I thought about impedance and capacitance.

FWIW: I just bought some Redco XLR connectors, and at $2 a pop, they are fantastic. MUCH better than other cheap XLR connectors I've used in the past.

If you are recording a stereo pair and you have one channel running through a 50' cable and the other through a 100', one channel IS taking twice as long to get back to you.

I time align my spots to my main pair by using longer cables. Works like a charm.

Bingo! We have a winner.

The last concert I recorded used 4 mics in a 2400+seat concert hall. They were connected to their respective cables and then put into a multi channel stage box. The cables for the box traveled to the back of the hall where the were input into a midas mixer, that mixer output a stereo signal to a sub mixer (mackie) in a different room where it was outputted again into a distribution amplifier. The output of the distribution amp was put into another mutli channel box and sent again to the back stage area of the hall where I was recording.

If there was any noise or signal loss due to multiple connections, I didn't notice it.

[juanpz]

everytime you put more than one cable together to make a run, you give interference a chance to degrade your signal at the connection point.

A great example would be a multiple mic cable run that happens to be just be the right wavelenght to pick up a local high power radio station.

I wouldn't worry about signals arriving at different times using varying length cables unless you are running 1000'+

If you do get to that point an Esnake over cat5 wouldn't have any problems.

I think that it is more likely a language/cultural translation issue than spam

[grindx]

When daisy chained, the connectors are also a point where noise might get in. Most folks don't solder the shield to the XLR tab which means the shielding stops at the solder cups. Use one continuous cable when possible.

I don't know how anyone could think that is spam but to explain the Enzo quote (founder of SPA Ferrari -- the famous car maker), if there are no extra connectors, it's impossible to have those connectors be points of fault. It's directly applicable to the conversation.

Mr. Rich, i've never heard nor seen you curse, Sir. You are coming out of your shell.

I've got some interesting files pertaining to this very topic. WIll post them in the next day or so.

[7rojo7]

No, I'm an American living in italy.
Yes, it means that if there weren't the connections then those problems pertaining to such connections would no longer influence the operation of a 100' run.
It's an allusion to another highly technical and precise profession, a modern day parable if you will. It has something to do with Murphy's Law and that makes it mystical.
Hope you don't ask me for my resume' or something
RFI problems may also become more likely to happen across the connections but it's also possible that EMI from AC lines could happen if the run were to cross one over a connection. same shit if it don't exist, it can't break. I try to make everything as simple as possible so that when something goes wrong, F Murphy, I can find it and resolve for Pi now (take a crack at that if you can)
what is spam anyway, My mom would heat it up in a pan and put it on toast in a pinch back in the 60's, it's better with mustard

Nothing quite like miscellaneous pork parts and gelatin stuffed into a can. Always cooked it with brown sugar here. YYYUUUUUUUMMMM! Sugar coated Spam.
I understand that Spam is still really popular in Hawaii.

Uh, really? What is the speed of light divided by 50 feet? It is NOT sound, it is electricity. Please provide the math to demonstrate it (and I'm really bad at math, so make it simple...).

My technique only work in halls that are east-facing, so that the waves are actually traveling faster than the speed of sound because of the additional velocity imparted by the rotation of the earth. I also check solar flare forecasts, so that everything stays linear phase coherent.

[loujudson]

Got it! I used to time align speakers with big rolls of cable, beacuse the closer ones with short cords sounded too fast! Gotta slow them down a bit...

kind of a transformer, but less wordy. TFG it's friday, even though it's saturday. lets not get all wound up like St. Ives

[Petrus]

The best way to time-align signals is to send the main stereo pair feed from the stagebox to recorder via geostationary satellite link, actually cheaper than renting the required 50+ miles of cable.

[aussie_techie]

multiple connectors can be a point of failure, however if its likely that a connector will get treated so badly that it likely to fail then multiple cables chained together will mean you only have to replace a short length when it does fail. especially when talking about installed cables just replacing the single cable on the end is much easier than replacing entire installed lines.

Anyway as long as things are similar on each channel and distances arnt to great the differences in any of this will be so small that its much more important to have a practical solution than worrying about these things.

[bishopthomas]

But finding the one 20' cable in a hundred foot run often takes longer than replacing one 100' cable. Either way, string 'em together; Ido it all the time with great success

Why don't you just time align the signal with Flux Capacitors. They pop up on ebay once in a while. The problem is the ending date is usually before the starting date!

You guys need to stop goofing around and start being a little more helpful. Everyone knows that a Flux Capacitor adds a serious amount of latency to the signal regardless of the time displacement. That and I have never been able to find a 1.21 gigawatt outlet at any concert hall I've been to.

Lets get real guys...
