Need schmatic for ep2500

Ch 1 has very shrill sound no yellow led action...start to turn up vol and red led lights right away......i suspect blown input on that ch.......also ch 1 bleeds into ch 2 output and causes red led to light up with no input to ch 2 just a 1kc tone on ch 1. are there any schematics in pdf form that i can download anywhere?....please help...thank you...ted kay

Http:// is a similar product, ie perfectly identical in most respects. This may not be trivial. Good luck.

Check preamps small parts! maybe you have change value capacitors and resistors!

The Amp clip light is always ON only the left channel and the same channel is not functioning by giving sound, please help

I looked at a schematic for EP2500 which is same but has a lower buss voltage than the EP4000. Below, the drive signal to the power stage is full wave rectified to illuminate the LED, d-c is presented to the LED if R128 & R138 has an a-c return. There is a line that can push-up the a-c return. It goes off to a connector that is unknown. I suspect the push-up voltage is not there. It could mean anything. I think its coming from the main transformer, Check for blow fuses.

Also the speaker output is protected with a "Crowbar" circuit. It is simply a Triac device (light dimmer) or two SCRs to prevent d-c from shorted output devices being applied to the speakers. which would cook the speaker coils. This may be activated when amp is turned on. Then there is the possibility of the output power devices - one or more shorted.
The amp needs to be checked out by a repair technician.

Im a candidate sound engineer, im strugling to set the bass drum from the mixer. how do i set it?

Bass drum by convention is ch1 on the board.
You need a good drum and a good mic

First set eq flat and pfl ch1, set gain control so drum just hits peak/or red when hit hard.

Send ch to drum group (1+2) on board, or route to master (L+R), depending on type board. Then listen to drum ONLY through the system, and adjust eq so it sounds good at low level then turn it up and keep it sounding good.
If it keeps peaking the ch then turn down gain.

There are toys (inserts) you can use noise gates and compressors if available,

Sound is objective and can not be learnt without doing it , good luck. remember good low level sound will always be better than really bad lound sound, start low make it good then make it loud.

Good drums do not need much eq. Get the drum right first.

Hope this helps
Thanks for using FixYa

Behringer EP2500 Clip light Channel 2 stays on & heatsink HOT!

There are so many components that can fail that troubleshooting this can be an expensive problem.

HINT: Put a 150 Watt light bulb in series with the power going into to limit current for/during troubleshooting.

Go through and compare the voltages on the teo channels. If power amp transistors have failed, likely the driver transistors also are gone.

Testing components in-circuit is very dificult. Resistors are pretty reliable and usually show damage by discoloration.

Furhter use before repairing MAY cause further damage.

Both fuses burnt and both clip and signal led on? seems to have full power behringer ep2500

Suspect an overload in either the power supply section or the devices on the main heat sink. In the power supply you are either looking at a transformer problem or semi-conductors associated with it. However since the clip and signal lights are on, I would go to the amp devices on the heat sink. If they are transistors test them with a Ohm Meter on the 1K setting in circuit even! You will soon notice which ones are gone! The meter will show like you had touch the test probes together!

The fuses have blown due to a short circuit, ie some part acting like it was a piece of wire. The chances are (with the LED's showing) it's the main amp semiconductors (on the heatsink) that have gone. The cause is either connecting a wrong (unsuitable) speaker(s) for the job, or letting the two wires (to each speaker) touch each other.

Trips on power up

It has a short circuit on the final steps of the outputs, maybe the common called "final transistors or power amplification IC (integrated Circuits)"are blown. You don't have the ability to resolve this problem, so take the unit to a facility authorized repair.

Behringer EP2500 trips immediately when turned on

Power supply section is overloading probably because of audio power amp problem.

Behringer EP2500 no output on CHANNEL 1

check all op amps for correct voltage swing +-should be equal,test output of op amps no voltage should be present, use chasis gnd as tester neg.check voltage regulation especially 12v or 15v +-.note some amps show unequal led indications when only 1 channel connected to a load.I will try to get some more info on this specific amp because i don't know this circuit well,keep in touch as you update though.
