Hey Guys , I am wanting to hook this horn up to a amp like this one below, Is this possible to do this or do i need a totally different amp. and do these horns have the same ohms rating as the speakers from a cabinet. Its obvious i know nothing about these as far as hooking them up. so please forgive my dumbness.

Jimmy, can you get us a pic of the actual horn, particularly any stickers or name plate that shows any connection information? Most likely on the back...
 
Re: how to hook this horn up?

Hello

First we need information of the horn.
Make - model - somewhere back should be information of it being 50/70/100V or perhaps even 8 ohms - possible switch for different power-settings - simply all you can find .

Amp sem to be Behringer Europower - which one of the two models.

Finally - please tell us what you wish to achieve with this setup. Single horn or multiple horns ? Coverage area - desired SPL - speech/music/what - etc etc

Generally - YES - it can be done - but as some here say - "it depends"
 
Re: how to hook this horn up?

I would use 2 wires- one from the + of the amp to the + of the horn.

And one from the - of the amp to the- of the horn.


Now-as others have said-what you get out of it depends on a lot of other missing information.

But my way will "make sound"-is that all you are interested in? Or does quality-level etc matter?
 
Re: how to hook this horn up?

I don't have the horn , so I can't look on the back of it yet. I haven't ordered a thing . I was just wanting to know if it could be done .i am planning on doing a speaking event (10k or5k run ) . The coverage will be about 1500 people on one city block. They do this thing rain or shine Nd IOC it's raining then I can't set my cabs up like I usually do . I am needing another option to doing this . I will find out what type of amp the behringer amp is , it's more than likely the smallest amp that they make from the one pictured. But I will find the make and model for y'all .

If it's something you are only likely to use once a year, why not hire in the kit you need? For that type of application I'd be looking at multiple horns with 100V line (or whatever is used down your way) transformers and matching PA amp.
 
Re: how to hook this horn up?

HELLO

NOW we have a starting point.

Impedance of such horns is usually quite high - a 50W horn on 50V line has impedance of 50ohms - so you could connect 6 horns parallel using just about any old wire - naturally heavier is better, but these things work with almost anything... 6 horns parallel would be 8.3ohms / 300W - so 2x150W@4ohms amp would be enough - although as usually - the bigger the better ( as long operator is sane...)

Now horn connection is nice in that you do not have to calculate impedances - as long they all are using same voltage, just add their powers up - so you can use 50W 30W 10W and even 2W simply connecting them parallel - as long you do not exeed the amplifiers capacity

If those speakers operate @ 70 V line, then they have higher impedance - at 100V it is still higher

To determine wich voltage your amp is capable driving " VOLTAGE = square root of ( POWER multiplied by IMPEDANCE ) " in case of 2x150W@4ohm = 1x300W@8ohm bridged we get square root of 2400 = 48,99V = close enough for nominal 50V line. 2x300W@4ohms = 600W8ohms - sqr of 4800 is 69,3V - and finally dual 600W@4ohm amp is capable of providing 100V line

Naturally you could drive 100V horn with ten watt mono amp, but then you would only get some 6volts to it... very quiet

So find out how many horns you are going to use and the voltage they use - naturally you can use bigger amps - easier on them amps, of course -

City block is what - about 150 yards - try to get them horns - about a dozen - really high - some ten meters/yards/ 33ft should be great - point them down to victims - fire away.

Do not expect any hifi - but right adjusted - speech clarity and announcements can be quite satisfactory - low cut 200-400Hz - depending of your horns


We did once an esplanade party with speakers podium in center and speakers all along up two 200 meters both direction - we aimed all speakers away from center to avoid situation, where folks hear same sound from front and back - luckily we had enogh amps and delays, so we could set time sync for them, too.

If you only have one amp - your choices might be one cluster in the middle of block high as you reasonably can - pointing along street both ways - or then distribute them evenly along block - aiming them from streetside across to othe side - here too higher is better ( of course if it is in Manhattan, there is possibility hanging them way too high... ).



There is this wonderful book - you might find it in your library - Sound System Engineering by Don & Carolyn Davis - Howard W. Sams&Co
- pages 331-341 gives you idea of speaker density = how many speakers you should use
- pages 401-405 give you math cocerning amps etc

That book has lots of other very useful information - along with mathematics.


After all this - please inform us afterwards how your street party turned out.

Have fun

So what is the photo of-if you don't have the gear?

Was this given to you? Or are you planning on getting something that "looks" like this?

Why were these products chosen?

But to be simple-they hook like every other loudspeaker.

The particulars of WHERE to hook up the wires (amp and speakers) depends on the specific products being used. So without that information it is tough to even start to guess.

Hey Ivan,

This is just a photo of what i am planning on getting something that looks like this, Why i choose these is because of them being weather proof and also because of loudness. I feel like it will do the job i am looking for. that is just my opinion though . I am open for suggestions.
 
Re: how to hook this horn up?

one thing i need to ask without sounding too stupid is, Does the driver come seperate from the horn lens on these or is it the horn lens and driver too in one thing?

Then since you don't already have it-you should investigate what is needed before you buy it.

You can't buy just by looks alone.

Without a specific model of both the speaker-the number of desired speakers-the specific amplifier there is no way to tell you how to specifically hook it up.

You many need to bridge the amp to get 70V, the taps will depend on the number of speakers and the size of the amp etc.

FIRST you define the needs-THEN select a product to fill those needs. You don't get the product and then "hope" it will do the job. It is a little late then.

Yes and yes. There are all kinds of different versions of "outdoor" paging speakers.

Some are more flexible than others. THere is also a pretty wide price range. It would help to know what sort of money you are looking to spend.
 
Re: how to hook this horn up?

I try to forget that end of the public address spectrum. Scratchy paging horns, even at low levels sound like they are about to explode.

If the system sounds bad it's because the components were chosen poorly and/or installed incorrectly and/or adjusted improperly and/or operated without much skill.

The same applies to "real" PA systems, too.

70V paging horn systems can sound very good and do their job effectively, it just doesn't happen very often.

The general population seems to accept poor quality public address sound, even when the system is in place for important information or even emergency warnings. Any jackass with 300 bucks and zero experience can buy a 30W 70V amp and eight small horns, and then attempt to provide sound reinforcement for a race track. Most people would not try to use the same budget for gear to run a band or DJ setup.

Edit: I'm not referring to the OP as a jackass! The jackass is likely someone's mom or dad or your brother-in-law with no audio experience whatsoever. Sorry if my comments sounded angry or unclear.

LOL No Offense Taken , I see what your saying , Not everybody in the world can do what we do. You have to be experienced enough to know what your doing and do the job right. Thats why i am here asking yall about it, I just want to make sure i do it right. :)
