How Can You Tell If Your Input Jack Is Stereo Or Mono?

3 terminals is Stereo Hot/Ground/Battery
2 terminals is Mono Hot/Ground

 

Stereo jacks have 3 lugs for wire connections, mono have 2.

I wouldn't sweat it unless your repair guy is a complete moron.

I'd recommend you take a crack at that type of repair yourself. Very simply to do. It'd cost you like a $1.50 for the jack and take maybe 15 minutes. Then, you don't have to let someone else muck with it!

 

Yes (of course you have to know how to solder). Also btw it has nothing to do with active/passive...

 

It does indeed, it's common to use a stereo jack as a switch on active basses to switch of the pre-amp when no jack is in....

 

and they're also used sometimes with recessed mounting for a cleaner profile.

 

I hate to be a stickler here, but the jack on your bass is an output jack, not an input jack. I know even Stewart McDonald, who should know better, call them that, but it is still wrong.

The signal is moving from the pickups, out the jack to the amp, not the other way around.

Just one of my pet peeves. Sorry, I'm just an old electronics tech.....

 

But, it's a 1/4" input jack because it's a female for the insertion of a 1/4" cable. The jack doesn't care whether the signal is coming, or going. It's about what kind of connection takes place.

 

Nope. Take a look at an effects pedal. You have an input jack and an output jack. They are generally identical, both female. "Input", as an electronics term, refers to the direction the signal is going. It has nothing to do with whether it is female or male.

 

What are? Barrel type input jacks? I think they come in mono too.

 

So, by this logic, should we see electronics stores selling identical jacks (input and output) as separate items simply because of how they are going to be used?

 

I suppose if one wanted to get technical, the signal is a closed loop or electrons would not flow. Therefore any electron flow moving one direction in one wire will be moving the other direction in the other. Soooo, One could call it what they want but yes, the bass is a source.

Now you've got me thinking, but I don't think I've seen a 'barrel' type mono 'in/out' jack.

 

Actually, when sold as a part they are just jacks. 1/4 female jacks. No need to specify input or output.
