Please check first your input source and confirm it is ok.-check speaker button is pressed(if you have one)-speaker cables are connected firmly-from amp side and speaker side-check mute button(also if you have one)is not pressed.-make reset for your system(power off and on).
if all above can not fix your problem you have to ask for help from service center.

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.

My amp has a protection light on need to know how to fix. When I pull the fuses out the power comes in but when I put the fuse back in the protection light comes back on


From the description your audio output transistors or ic's have a short causing a load problem activating the protection circuit. Turn volume right down, power off, remove speaker wires from the back, power on! if protection kicks on it is the audio outputs in the receiver, if not! check speaker wires for shorts, hook back one at a time until defective wire or speaker is located. The audio outputs will need to be addressed by a technician since there is complexity involved.

Hey, i bought a new pair of samson auro D415 speakers and i connect them in parallel because one of my main mixer outputs ain't working.but even if al my signal gains and fader levels are low,the peak...


Check only one active speaker at the mixer output and report the results.
Connect only one of the audio inputs from the power amp at the mixer output (and the passive speakers at the output) and report the results.
Sometimes (in parallel connections) there are interferences from the volume controls.

In case of a problem or clarification or further details needed, don't hesitate to post me a reply before rejecting my answer.
If you are satisfied, rate my solution with the "thumbs" or (even better) add a testimonial.

Check you inputs to verify you have a signal coming in, if signal then check outputs try a speaker that you know is working and plug it in if that speaker plays then the subs/ or speaker wiring is bad, if it doens't play then you probably have a blown output transistor on the amp or possibly a terminal ground/positive has come loose on the inside..

Brand New MRP-M500 light is on but there is no sound


Try making sure your sound input to the amp is good (could be a bad output from the radio or RCA cable), could also be a bad input from the amp, bad outputs from the amp or even a bad sub. You have to check each of these and eliminate the problem. I would make sure you have a good audio signal to the amp first.

NO sound through the AMP even though the power light comes on


Not a fuse. First thing, to check your speaker (amp unplugged, of course), touch the + and - speaker connections to a 9V battery. If you don't hear a pop sound then your speaker is blown. Thus, no output sound. If speaker is OK, then the output IC is your problem.

MPA-101 Amplifier powers on, receives source signal, the fuse is not blown inside, but no sound comes out of the amplifier. The amp is pretty new, doesn't even have dust inside the unit.


Hello, is this a Radio Shack PA amp or Jamo amp? The unit is probably in "Protect" mode. Is this a PA system or a receiver...receivers have a protection circuit that will not let the speaker relay activate if the amplifier output section is shorted and sending voltage towards the speakers...so they won't fry!!The speaker relay should activate within 3 to 5 seconds if your output section is ok.

Amp no longer turning on


Do the speakers push out or pull in when power is applied?

If not, how did you determine that is has DC on the speaker outputs?

My amp is not working


For the visonik, you should check your speakers. You can use a D-cell battery. Remove the speaker wires from the amp and connect each speaker across the battery (for no longer than a few seconds). The speaker should pop each time the wires are touched to the battery. If they don't, the speaker is defective (assuming the battery isn't dead).

If the speakers are OK, you need to confirm that you have a good signal feeding the amp. You can use the RCA cables from another working amp in the vehicle. Do this with the amp that had the power light lit.

If you have signal going to the amp and the speakers are OK, the only two things left are the power supply feeding the amp (from the battery) and the amp. If you have B+ and remote voltage AND a good ground, the amp is defective.







For the pyramid, the amplifier probably has shorted output transistors. The amplifier will have to be repaired.
