William, why do you keep doing this?

** The Sommerwanker fails to read his own words, let alone other's.


If you had bothered to do your research properly you will have discovered
that the Behringer B215 is a loudspeaker.

** The heading alone makes that clear.

Then the pic backs it up.

It has no internal amplifiers, the jack sockets are simply in parallel
with the Speakon sockets and do exactly the same job.

** But Speakons do it way better and are not prone to shorting.


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

** Yep - it a stereo jack with the ring contact wired to the tip contact
via the PCB.

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.

** Seen the exact same thing myself.

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.

Gotta be smarter then the "average bear" if repairs are you game .....

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 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.


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.
