SOURCE: behringer eurolive b1520 pro speakers duller than the other

Hi,

Best and safest is to have a good electronicus check it out.
i've worked on these kind off things, and i assure you not everything can be simply solved without experience, especially when talking about a decent type like Behringer ;)...

Hope this is helpful, and greetings,

Olivier.

SOURCE: clip light

It sounds like one side of the power amp has shorted. May be hazardous to the speaker so best take it to a shop for repair. If speaker stills sounds OK, probably the clip detector transistors have failed.

SOURCE: I have a 1200watt amp

I'd need to know more about the amp, but don't forget, amps are rated as their max power...
So lets take a 300W/channel stereo amp at 8 ohms.
Ok, it's stereo, so there's 600W
But the amp is capable of 4 ohm loads...well, now you can deliver 600W/channel, for a total of 1200W
In this scenario, your amp is doing exactly what it was designed to do with those speakers.
If you wanted to get the full 1200W out of the amp, you'd have to hook up 2 more speakers in parallel to the ones already there. This drops the impedance to 4 ohms per channel = 600W / channel.
Yes, the power is split among the apeakers...300W per speaker into 4 speakers = 1200W
so any way you look at it, there's your 1200W

Behringer b212 power keeps shutting off


What a surprise! This is not unusual. If you drive these hard they do tend to shut down. If you are not driving it hard and are not running into clipping there is obviously a fault and it will have to go back to Behringer.

How to wire up outboard effects, poweramps to mixer. Out to sub, mains, monitors each with own poweramp, and several outboard effects, eq's, comp/lim/gate, sonic maximizer, quadraverb, crossover.


I'd need to know what mixer you have, to know if there is a [line out] connection socket and an [internal amp in] connection socket.

"each with own poweramp" I presume means the ep1500's and NOT that the speakers are active (ie containing amps)

***If any of your speakers are active, ask the question again, with more detail.***

So if all your speakers are passive, I offer the following.

I assume there is [effect send] and [effect return] on the mixer

effect send>quadraverb>effect return

mixer line out > eq > compressor > sonic maximizer > crossover

sub output of crossover> amp > sub
high output of crossover to mixer's internal amp input
mixer's speaker output > main speakers

monitor output > other side of eq (>other side of compressor if desired, but use sparingly ) > other side of sonic max if it is true stereo , otherwise skip > amp > monitors

If your mixer doesn't have an input to its internal amp, we are "back to the drawing board"
With questions like this it pays to give as much detail as possible; model and make of each component etc
I have done my best with the the info you have provided.
Don't feed amp outputs into powered speakers

Behringer Xenyx 1622FX - How do i get a passive stage monitor to work?


You need to send your signal from the mixer to an amplifier and then go from the amp to your speakers.

Alternatively, buy a pair of active speakers.

Just bought. New b205d power is on but no sound


These are a nice unit... just bought three of them that were dead... I have repaired one so far. I assume you mean the blue LED is on indicating power is on. What I want you to test is if injecting signal on the BACK of the unit jack (power amp in) will create sound. If it won't then better exercise your warranty. The one unit I have completed repair had a bad 15 volt regulator in it... the second that is almost fixed somebody had blasted the input circuits... probably connected to a speaker output... don't do it... these are LINE and MIC level units. If you need to tap off a speaker output, use a DI box with the unit. The third unit I have not received yet. Drummer used the repaired one as monitor last night and was impressed with the power this unit has.

I want to connect two passive b212 and 6 active b215 , i will use two active b215 for monitors ..... i am using a PMP 3000 Please advice,also where can i get a detailed numbered illustrations sheet for...


The passive speakers connect to the main outputs using Speakon connectors on the back.

You will use Balanced connections (TRS) to the main L and R connections on top to the active speakers. Daisy chain 3 active on each of the L and R top connectors.

You can download a user manual if you don't have one.

http://www.behringer.com/EN/downloads/pdf/PMP1000_P0566_M_EN.pdf

ALSO PLEASE read my tip regarding a hazard when using Speakon to 1/4 inch speaker cables on channel "A" in the FIXYA tips for PMP mixers. The barrel of the channel A 1/4 inch is the HOT side of the signal to the speaker instead of the tip.

Sound from monitor speakers distorted and high-pitched


Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages.
Good Luck!
