1/4" phone jack replacement for Behringer 215 speaker.

This Behringer 215 speaker has two 1/4" phone jacks that are wired in
parallel. It also has two Speakon jacks wired in parallel to facilitate
adding extra speakers to the system. The unit came to me with one broken
1/4" phone jack. The picture of the pc board is here.
http://webpages.charter.net/mrfixiter/images/Electronics/Behringer/pc-board.jpg
The Speakon jacks were fastened to the back panel of the cabinet with two
screws per jack. On the other end of the screw was a nut. Unfortunately, the
nut wasn't anchored to anything so it was futile to try and remove the
screw. The circuit board prevented me from inserting any tool in there to
hold the nut while I was turning the screw. You can see the results. I
replaced the Speakon jacks, no problem.

With the help of a Mouser telephone tech to match the original part, I
ordered replacement 1/4" phone jacks, manufacturer part number NYS232.
http://www.mouser.com/ProductDetail/REAN/NYS232/?qs=%2fha2pyFadujcNYWYyUSyMSHhOqDb3buvV%252b7cmiFFRuQ%3d
The owner suggested I replaced both of them as long as I had it apart. The
parts arrived and I installed them. I wired everything back in place.
Something told me to check the input impedance of the speaker with a
multimeter just to make sure it was wired probably. It was a good thing I
did. It measured a direct short from the speaker plug input. After searching
up and down for a short, I didn't find any until I inserted the phone plug
into the jack. That's when an internal contact in the jack switched to a
different position and shorted out the plug. Ok, I guess this jack will not
work on this pc board. I called Behringer's parts department and had them
research the original part. After a day or two of researching, I received a
call back from Behringer and ordered the parts. I received the parts today.
Excited to finally get the speaker repaired, I removed the Mouser jacks and
put in the Behringer jacks, same thing. Direct short across the input
terminals. Then I looked inside and noticed there wasn't any difference in
the terminal configuration between the Mouser jack and the replacement
Behringer jack. I will call Behringer back on Monday to discuss this
situation but meanwhile, do any of you know what kind of 1/4" phone jack is
supposed to fit on this pc board?

Thanks for your reply.

The jack sockets should be "mono" versions - stereo ones will short
out as you have found.

Thanks for the confirmation of the mono plug and the trick to remove the

Another piece of information here. If I plug in a stereo phone plug, then
there is no short circuit. Is there some industry standard to use stereo
phone plugs in this type of application?

** No way.

Mono plugs are always used for speaker leads.

Just a thought, are the outputs in antiphase and just one of them is
exhibiting this "fault" if you check to chassis ground?
 
It's amazing Fran Allyson didn't jump all over you.

The 1/4" phone jack is (supposedly) a balanced line-level input. If you plug a
mono plug into it, the plug's sleeve will short the jack's ring to ground.
This is normal; there's nothing inherently wrong with this. It's one way
unbalanced signals can be connected to balanced inputs.

I suspect you have a problem that isn't really a problem.

Hi William,

I think if you take an ohmmeter and connect it to a speaker input, and it
measures the lowest reading that it can display, that would be cause for
concern. The only time this happens is when the stereo plug is inserted into
the jack even when the plug isn't connected to anything. How do you perceive
that this isn't a problem?

Thanks for your reply.

I'm not sure what you mean by outputs. Do you mean the amplifier outputs? I
have not connected it to any amplifier as of yet. I'm just measuring the dc
resistance of the speaker at the input jack.

As far as I can tell, this isn't a speaker input -- it's a balanced amplifier
input. There is no reason why a mono plug or stereo plug should show a short.

Your description of what's going on seems inconsistent and confused.

Hi William,

The are two Speakon and two 1/4" phone jacks wired in parallel that are
situated in the back of the speaker cabinet. It's not a powered speaker. The
inside of the speaker cabinet contains a crossover pc board, a woofer, and a
midrange speaker. When I replaced the damaged 1/4" phone jack and checked
continuity across the pc board input with the speakers disconnected, it
measured open circuit. When I put a monaural phone plug into the jack, I
rechecked the continuity and it was shorted. The monaural phone plug was not
connected to anything on the other end so the short had to becoming from the
jack itself. Does that make sense?

William, why do you keep doing this?

If you had bothered to do your research properly you will have discovered
that the Behringer B215 is a loudspeaker.
It has no internal amplifiers, the jack sockets are simply in parallel with
the Speakon sockets and do exactly the same job.

Clearly there is a problem with the replacement jack socket that seems to
provide a short with a mono jack plug inserted in it.


David, my usual technique where the original socket cannot easily be
replaced is to simply use a chassis mounted switched jack socket hard wired
to the PCB, if space allows it, after carefully working out what connections
to connect to where.

Hi Gareth,

There is lots of space to drill a new hole and mount another jack. Then it
doesn't have to fit the pc board directly. Why would it have to be a
switched jack? What would it be switching?

A switched jack will just cover all possibilities. You can use the
switching or ignore it, the cost is pretty much the same.

I can't see how a switched jack might be used in this unit, but nor can I
see how inserting a mono jack plug into the replacement socket can cause a
short, so something in the wiring is amiss.

You might not need to drill a new hole, you may be able to fit the chassis
mounting socket in the original hole, and just run wires from it to the PCB.
Hot melt glue or silicone sealant will secure and insulate it.

I did do my research properly, because I knew I would be subjected to this

SPEAKER, and the 1/4" phone jack is a balanced input. READ WHAT IT SAYS on

** The B215 is a passive speaker - as stated at the top of the first page
of the link.

http://www.behringer.com/EN/Products/B215.aspx

Says: " * 2 professional speaker connectors (compatible with Neutrik Speakon
connectors) plus ź'' jack connectors."


The "details" tab give you a different model - the B215D which
incorporates a class D amplifier.

The OP made it VERY clear which model he was on about.

If there's something wrong, it's with Berenger's product sheet -- not my
ability to read or understand it. Or perhaps David Farber gave the wrong model
number. This might very well be the case, because the drawing doesn't show a
