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/mrfixite...r/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/...7cmiFF RuQ%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?

there is no short circuit. Is there some industry standard to use stereo

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.

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

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?

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

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.

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.

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
Speakon connection.

I normally don't ask for apologies -- but in this case, I'll make an

It may be easiest in this case to use this "wrong" socket by modifying the
PCB traces, thus retaining the mounting between PCB and backplate and having
an easily replaceable part in the future.

It is not uncommon now to find chinese manufactured parts that look very
similar to off the shelf western parts but having different pinouts. I seem
to remember our Mr Cook reporting something along these lines here a while
ago (TRS = RTS?)

One I saw recently was a PCB mount switched jack socket where the switched
terminals were on the opposite side of the socket to just about every other
switched jack socket in existance, so the switching action would not work
with a generic replacement, even though it fitted perfectly.
(this was either a Laney or Crate guitar combo)

Seems this may be the case here.

Luckily, it was possible to remove the metal parts from the socket and
reverse them.

Seems both Re-An and Cliff can supply mirror image versions - if you want
them.

I did do my research properly, because I knew I would be subjected to this
crap. Did you look at the B215 link I supplied? The B215 is A POWERED
SPEAKER, and the 1/4" phone jack is a balanced input. READ WHAT IT SAYS on
the Details tab.

** 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 ¼'' 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.


Maybe. You will perhaps forgive me for making the not-unreasonable assumption
that a product sheet is supposed to be about one product, not two. (Yes, I saw
the B215D model number on the Details page.)

I'm still wondering why any company would use a stereo connector for a mono
circuit -- but who said the world is rational?

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.

David,

I have just found a switched jack socket in my workshop similar to the
Switchcraft style ones in your photo.
Looking at the left PCB print in your photo, the one I have here connects
the jack centre pin to the "12 O'clock" contact and the jack ground to the
"7 O'clock contact. However, inserting the jack also connects the jack
ground to the "3 O'clock" contact, meaning jack centre pin and ground are
shorted together since the PCB has 12 O'clock and 3 O'clock positions
shorted.
Remove this shorting on the PCB and your socket will probably work OK.

Alternatively, just remove the 3 Oclock pin from the socket, though the
first method is much safer and more sensible.


Cheers,

Gareth.

Hi Gareth,

I called Behringer parts back this morning and told them I received the
wrong parts and why they were the wrong parts. I got a call back after some
research was done and they are shipping me the correct parts this time. They
can't mess this order up twice, can they? (-:

The pc board is multi-layered so I really don't want to mess with that.
Let's see if the replacement parts are the correct ones.

Thanks for your reply.

I received the new jacks and they were the correct ones. The speaker works
fine now. I did notice one strange thing about the midrange driver. When I
went to push the connectors onto the terminal block, the driver started to
rotate in its mount. I didn't see any mounting screws that would hold it
securely in place. This can't be normal can it?

Thanks for your reply.

In my experience with Behringer, having anything of theirs operate correctly for an expected period of time is abnormal. I am not surprised they sent you the wrong part, I am surprised you apparently spoke with a live human on-shore about it.
