Monitor Plug Help! What kind of plug is this?

It goes to my new JBL LSR 4328P

It came 1 per monitor.



The manual reads:


AC POWER CONNECTIONS

The LSR4300 voltage is set at the factory for use with either 100V-125V (U.S.) or 200V-250V. The ground terminal of the IEC plug is required by wiring codes and regulations. It must always be connected to the electrical installation safety ground. CAUTION: Do not use three-pin-to-two-pin AC adapters to defeat the ground.

The LSR4300-Series units have carefully designed internal grounding and balanced inputs and outputs to reduce the possiblity of ground loops (hum). If hum occurs, see Appendix C on page 34 in this manual for suggested audio signal wiring, system grounding hits and other preventive measures.


Help!? [X(]

post deleted after read your post properly. Not entirely sure now, what the problem is.

If it's come with a euro power cable, I'd assume it's set at the factory to 240V (euro), and absolutely no use to you whatsoever.

Thanks!

So basically I need one of these?




Secondly, I don't see a switch to change the voltage/power. Here's the back of the speaker:




What'cha think? Also, I thought I would need a USA 3-prong for this type of thing? Do they make EURO to 3-prong adapters, or is this not necessary?

Thanks!!!

Actually... all you need is a standard 120 VAC IEC A/C cable. They are the same ones that are common with most pro audio gear and high end appliances. You can actually buy them at Best Buy and places like that.

The monitors should "see" the correct voltage and no switching will be required.

Ummm. Actually it appears that the 4328"P" designation may be for 230 Volt use.... Hmmmmm

I have the "P" and I thought it was just for "powered" - anyway, mine is US model with standard US IEC plugs.

If the monitor is configured to use 230V, you can't just use a prong-adapter.

You shouldn't listen to anything here, really - you should call JBL and get it from the horse's mouth.

Did you buy these used? From a US buyer? Why did they come with that Euro plug? Call JBL. Don't fry your shit.

@SRS: From his OP you can see that the monitors come "factory configured" for one or the other voltage, so even if it has a standard US 3 prong input, if it's configured for the higher voltage he could have problems. (although to me having it be the other way around would be more likely to hurt the speaker).

The above post is true. Just call JBL and ask them for clarification. The good thing is... you won't fry your monitors if you plug them in to 120 VAC and they are configured for 230. They probably just won't work, or it will be obvious that the voltage is wrong. The other way around... I CERTAINLY would not recommend that. Mine came with both the Euro style and the US IEC. They were purchased directly from JBL in Northridge, CA.

Thanks everyone. This is actually encouraging, perhaps this means that both will work for my monitors? If yours had both plugs, and work with the USA (lower voltage), perhaps that means mine will too?

I actually got these from a dealer in NYC (whom I've contacted), and they were shipped from southern Cali. Brand new in the box. It's a dealer I've dealt with before on eBay, and I've contacted them before and have gotten good response from them. Perhaps it was a mis pack at the factory.

I'll definitely call JBL tomorrow though and get the scoop. I'll post the findings here.

Thanks again everybody.

I may be screwed. The plug back says 230V~.50Hz, the one in the picture above says 120V~.60Hz. Mine say 130W as well below.

Monitor Plug Help! What kind of plug is this?

Yes. The cable and plug end is rated for that level of voltage. That's just a voltage rating indication.
I'm sure JBL or a dealer will be able to clear this up today for you. Shipped new from the factory in Northridge to NY is very encouraging that they are for the US market/voltages.

Everyone, here is an update:

I contacted JBL today and there are definitely 2 different models, one a 120 and the other a 220. I was mistakenly sent the 220; the 220 will obviously not work with a 120 outlet.

It was also a mispick that the package included the Euro cable. Whether or not it would have worked with an adapter is moot; the voltage would have been a bust.

SO. . . . here's to working with a good company! I'm packing them up, they're sending me a FedEx receipt, and are sending replacements. These things happen. I'm not pissed, I still got my mounts up and ready, and hell, I'm going to get all that wood stained this weekend and finished and ready for the speakers when they DO get here!

What's another week to a lifetime of waiting!? Inconvenient, but that's how the cookie crumbles sometimes!!

Thank you all for your help; maybe it was a learning experience for all.

Here's how they'll look up and mounted (but the wood will be stained!)

Try reading it twice before giving that advice. I wrote what you've written before backspacing it all.



Like I said mate, your speakers seem to have been supplied as 250V AC, and you'll need to get them swapped for 110V speakers else you'll do some damage.

I do have a concern that unless you're very very tall (and feel like going deaf), your speakers are both very close and very high up, and the sound will start to 'form up' quite far behind you. From where you're sat, the bass particularly will be quite wrong.

My room is 11 x 9. My mix position is at 38% from the back/front of the room. The speakers are at the same distance from each other as they are to my mix position. I don't have to mix at maximum volume, and these speakers have the room treatment technology; I also have tons of bass trapping treatment done. I think the picture is deceptive as to how high they really are.

You do the best with what you have.

Best

No sweat BigD. Not a big "backspacer" on GS. I stick with what I wrote, but sometimes add too it if needed. I feel confident that plugging a 230 or 250 volt appliance into 120 volts will not cause any damage. The other way around, as I said before, could cause a problem, but even then likely not as the protection circuit/fuse would more than likely protect them. Hence my advice. The OP did the right thing and verified it with JBL and all is well.

As far as the mounting position... I would be just as concerned with that position too, as it appears odd for nearfields. Unless your intention is midfield, which you implied it was not.

Here's a better pic; if you could see me in the picture, you'll see that they're not very high above my head.

Im actually living in america and want to order them for EU. I am a bit confused, is there a different model I need to order or does every model have the switch for either country and I just need to get the plug. Spindle box could you let me know where you purchased yours on ebay? thanks.

OH, Anna, I get you now. Yeah, you need to get the EURO plug pictured in THIS thread. Make sure that you tell them you need it. I know at one point they did. In fact, they were in my house! LOL.

It will be the same model, but the plug will be different, and I think there is some sort of wiring they do differently, but am not totally sure. I know it wasn't just a simple plug or adapter fix.
