AUX input TRS or TRRS

Freel2,

I recently replace my AUX input because my Daughter was complaining that it wasn't working.

I did read on here that the new socket had to be separated but it was not obvious what to. I did figure it out.

Upon removal I noticed that the connector has 4 conductors.

For those that don't know

TRS --> has three segments

TRRS --> has four segments

I bought a TRRS cable and it works really well.

It could be that the cable is just made better but I'm going to assume that its the preferred choice until someone can prove me wrong.

I did check the wiring diagram and eventually the extra conductor does connect to ground but it goes a significant distance with two twisted pairs.

Do I know for sure that TRRS will eliminate the ground loop buzzing.......No

But I am 100% sticking with the TRRS cable.

Happy motoring

Paul

AFAIK there are two types of TRRS connecting. CTIA and OMTP ; where the Ground and Mic are swapped.

Your pic is TRRS in the CTIA arrangement Jules

From your Circuit Diagram I believe that you only need TRS Cable, you are not using the Mic feed.

Unlike the TS cables, both TRS and TRRS contain separate shielded audio conductors (for Left, Right Speakers [and Mic TRRS) if necessary. Like most things the price decides quality of materials and manufacture.

Some links to internet ---

What is the difference between TS, TRS and TRRS?
TS, TRS and TRRS are abbreviations for Tip/Sleeve, Tip/Ring/Sleeve and Tip/Ring/Ring/Sleeve. These often refer to the amount of contacts on the end of an Auxiliary cable or Quarter Inch cable. A TS cable is often thought of as mono, as it only has one contact and is only going to give one solid sound signal. A TRS is often though of as stereo, as the addition of the ring gives us two contacts allowing us a left and right audio channel. Finally, a TRRS cable is usually going to include both a left and right channel as well as a microphone channel. These TRRS cable are often found at the end of headset or earbud sets that include an inline controller and allow You to speak using a small built in microphone. The easiest way to identify the three of these is to count the number of black rings on the head of the cable. One ring for TS, two for TRS and three for TRRS.

There are variations on the way the conductors are shielded and there can be twisted pairs, single shielded, or shielded twisted pairs. (plus I am sure other configurations)

Good feedback!!!!

Thanks

I did drive my Daughters LR2 today (it was mine but not anymore) and it has a Bluetooth device for Apple Car Play and the sound quality is excellent.

Having said that I do believe that the more expensive TRRS cable is just better quality and that a well made TRS cable would likely work just as well.

If I really want to know then I would need to do an A --> B comparison of CTIA and OMTP made by the same vendor and a TRS cable as well (A --> B then the winner take on C).

I don't need to know that bad so I am just keeping what works.

Here is what my Son bought for my daughter in case anyone is interested

It is not expensive at all

Take care
