Troubleshooting
After powered without any response
Measure the outlet with a multimeter to check if there is power available and when no multimeter, you can have a test pencil. If the power supply is normal and the amplifier still no response when powered then there is something wrong with the amplifier, need a professional person to check it.
No signal output
- First, check if the signal input is right.
Check the connect of XLR, if the 2 and 3 reverted or the ground is reliable. Different circuitry designs will have different connect ways to the XLR, please follow the 2+, 3- to soldering. It can not be judged by comparing it with other amplifiers (including other amplifiers in the same factory). - The signal light doesn’t light up
If all the signal input is fine and the signal light doesn’t light up then may the amplifier has failed, you need to ask the professional person to check it. - Signal input normal but no sound
The signal light will flash with the change of input Volume, but now sound out, then you can check the connect of speakon if it is connected good and the wires are connected right(some times the problem of the wires connect, check its±1 and ±2 connect), after the check above if still no sound out, please change a speaker cable and check again. Because some times also caused by the bad quality of the Speakon connector problem of the amplifier. Through experience, it may be caused by the bad connection of some plugs and the socket.
Output sound distortion
- After checking, the signal and loudspeaker are fine and still can hear distortion when small sound, then may the amplifier has failed, need a professional person to check it.
- Some frequency band has distortion
First, check if the loudspeaker is already overloaded, normally judge it in 95-105dB for higher SPL we don’t comment here. Here we just think about the failure recovery of the amplifier. If in the middle have some rupture sound and smaller volume more obvious, then it should be crossover distortion of the amplifier and this kind of distortion is easy to confuse with the failure of the loudspeaker itself. If the amplifier has a problem then you should send it back to the manufacturer for repair. - Distortion is High SPL
If the sound is normal when small volume and then you need to check the limit SPL of the loudspeaker. You can listen to it at a suitable volume and if the clip light works, then you need to reduce the output. Both loudspeakers and amplifiers have limited, you should use them within their limit if in very high SPL they have distortion you should take care of them and reduce the output to the right position.
The protection light blinks
When the PROT light works, the amplifier into the protection mode.
- Maybe the temperature is too high or output short or near short and they are not failures they can recover after you can use them normally. But overheating will take more time to recover. Also when overheating happened you should check the fan and the temperature of the install environment, if you should solve the problem then can use an amplifier. If you think the speaker was short, you can with a multimeter to check if the resist is lower than 2 ohms or 1 ohm with DC(Please calibrate the multimeter to measure for accuracy because of the small resistance).
- If the PROT light always lights up then it should be the problem with the amplifier, you should send it back to professional person for repair.
Hum in the system
- Hum exists even when there is no signal Please keep the amplifier away from the earth wire of power supply cables, just connect the firewire and zero wire, no ground wire. If the hum is still existing, it can be judged that there are some problems with the amplifier. Please get in touch with professionals.
- Hum exists when the system is completely connected This is caused by the different ground voltages in different devices in the system and mainly happens when the power supply is under a three-phase distribution condition, each device is connected to a different phase. This is not caused by the amplifier.
Solution experiences, just for reference
A. Combing the electricity, the power distribution box using the same one for all if possible.
B. Make sure the grounding wire potential is zero and force the different grounding wires to the same level, if the grounding wire Itself is charged, indicating that the wire may be connected with the zero line. Please solve this problem.
C. If unavailable above, then only disconnect the ground wires of all devices, which helps to reduce the AC. But this is not meet the safe use of electricity, users must know what will happen if to do in this way. We do not recommend floating use.
The amplifier is required maintenance in the condition below:
- If the amplifier smokes or smells burning.
- If the cabinet has severe indentation and deformation
- If the amplifier is dipped into the water
- If the internal components loosen
- If the AC breaker skips out when the current increases.
