Muddle over left/right channel of TRS plug

P

Peter

Guest
I have a 3.5mm TRS plug which is prewired. It looks like this

http://www.mycablemart.com/store/images/products/1085_large.jpg

The tip of that TRS plug is connected to the red wire (RIGHT
channel).

Has that been done correctly? I thought the tip of the TRS plug is
the LEFT channel.

(I also have a 3.5mm TRS socket which is prewired and the red wire is
also the tip.)

Does it matter? If it's backwards then just reverse the RCA's?

The tip is normally left - as left is conventionally follows mono as
regards wiring convention.

As to colours, in the UK some pro stuff uses red and green as per the
naval convention - ie red (port) left, green (starboard) right. Whereas in
domestic stuff red is usually right. Just to add to the confusion.

As far as the RCA plugs are concerned, the Red plug has long been Right.

Pro gear doesn't use RCA plugs. But can use TRS.

As a mnemonic, I think of it as a political thing (right=red, left=blue
[i.e., not-red]).

Does it matter? Can you tell "right" from "left" by ear? Lessee, strings
on the left, brass on the right, percussion in back...

Of course if it's wrong, just fire up the ol' soldering iron, and swap
them. Takes about four minutes.

Cheers!

That's a recent innovation that came with Bush II. Historically, the "Reds"
have been the commies. ;-)

Is "TRS" a mnemonic for something? All I can think of when I see it is
the Radio Shack/Tandy TRS-80, pronounced "Trash 80". ;-)

Thanks,

Tip ring sleeve. Unbalanced stereo or balanced mono. Or sometimes a mono
in and out on a mixer.

I'd guess originally designed for telephone exchanges. In the UK, the
telephone one is known as a type 316 and has a smaller tip than stereo
jack plugs. And is still in use - must have been designed over 100 years
ago. Dunno if the US one is the same.

Oh, yes - the US has been using "Tip & Ring" for about as long as there
have been telephone exchanges. (a hundred years?) :)

My cousin Owen inherited Uncle Dick's farm - they still have a
wall-mounted crank-style phone with the separate earpiece similar to this:
http://youngandthewireless.com/emptying-nests/wp-content/uploads/2009/05/old_telephone.jpg
[mind the wrap]
and they have an early phone book - most of the phone numbers were two
digits! (Circuit & phone). (it wasn't a very big town. ;-)

If you're curious, it's Lake Crystal, MN.

Cheers!

But, I think, more commomly known as a "Jack plug". Usually available in
2.5mm, 3.5mm and 1/4". The P.O. type 316 is 1/4", as are the ones more
commonly used in the applications Dave has suggested.

In telephone usage, the 1/4" variety can frequently be found with more
contacts in the form of additional rings when used, for example, with a
headset.

"jack plug" seems to be a British usage - elsewhere it is an oxymoron
- a plug is inserted into a jack, so you can't have a "jack plug". In
the US and Canada, the connectors are more commonly known as "phone
plug" (male) and "phone jack" (female).

I recall seeing a version slightly smaller than 1/4" (0.216?)
somewhere.

The telco versions have a different tip shape than the commercial
versions.

Seems strange to me as 'Jack' is a common name denoting male. Jack rabbit,
jack tar, etc. Wonder what the root is in this case?
But would they *really* talk about a 'phone plug' in a telephone exchange?
You don't in a sound studio where such things are used in a patch bay -
known as a jackfield. The leads with a plug on both ends are known as
patch cords or double enders. But of course jargon varies even in the same
country - never mine different ones.

If it's the telecom or pro version, called bantam.

The telco versions have a different tip shape than the commercial
versions.

One thing to note is if you insert a 1/4 stereo to a jack socket designed
for a telco type it can short things out - it pushes the tip contact onto
the frame.
