What is the reason why the mixer s power indicator keeps flashing and not always on?

1.The output must be relayed before it can reach the speaker. Level.

Generally speaking, the front board is good, and the power amplifier board should also be good, and it is most likely that there is a problem with the delay protection circuit.

The mixer's power indicator keeps flashing and not always on. The reason should be that there is a fault in the display indicator where this switch is controlled. You should ask a professional to do it.

The power indicator of the mixer, if it is normal. It means that the frequency you adjust is normal, if he keeps flashing, it means that he is not within this frequency range and the signal is not good.

The flashing power indicator is generally caused by poor contact or voltage instability.

The total volume of the mixer generally has two level lights to indicate the left and right channels respectively, and the inconsistency of the flashing means that the volume of the left and right channels is not the same, and it may be that your fader is not consistent.

The black mode button on the upper left of the main push is hit to normal (solo); In the source area at the top left of the mode button, only the main mix is pressed, and the level indicates the master volume (after the main fader). The reason for the situation you described is that when the mode key is pressed (pfl:

Pre-fader listening), when the solo key of a channel is pressed, the level is indicated as the pre-fader (post-gain) signal of that channel.

What is the reason why the mechanical motor of the power supply of the dispatching station does not flash brightly? That's ruthless enough, but it's actually a relatively simple truth. If he doesn't shine, it's sunny.

What is the reason why the power indicator light of the mixer has flashed and is not always on? The indicator light on the roof is flashing, but there is electricity.

The speaker power indicator is not on, if you can determine that the power socket has power, then the possible reasons are:

6. There is a component on the circuit board that is broken (brokendown) and the power supply part or fuse is damaged.

A speaker is a device that converts an audio signal into sound. Generally speaking, it means that the speaker host cabinet or subwoofer cabinet has its own power amplifier, and the audio signal is amplified and the sound is played back by the speaker itself, making it louder.

The speaker is the terminal of the entire audio system, and its function is to convert the audio electrical energy into the corresponding sound energy and radiate it into the space. It is an extremely important part of the sound system, and it is responsible for converting electrical signals into acoustic signals for direct listening by the human ear.

Don't worry, the speaker power indicator is not on, if you can determine that the power socket has electricity, the possible reasons are: 1, the speaker power switch is damaged 2, the AC fuse is burned 3, the power transformer is damaged 4, the rectifier circuit is damaged 5, the DC fuse is burned 6, and the circuit board has a component open circuit (breakdown) that causes damage to the power supply part or the fuse.

If you can determine that there is electricity at the electrical outlet, the possible reasons are:

1. The speaker power switch is damaged.

2. The AC fuse is burned.

3. The power transformer is damaged.

4. The rectifier circuit is damaged.

5. The DC fuse is burned.

The transformer does not transmit 11V electricity, is the transformer broken?

Summary. The light on the mixer is still flashing, so it may be that the mixer hasn't turned off yet.

However, due to the high requirements for sound quality of the mixer, the filter capacitor used in the power supply consideration circuit is larger, and some power will be stored after shutdown, so that some indicators will glow, and the lights will naturally go out with the passage of discharge time.

The mixer light flashed and flashed.

The light on the mixer is still flashing, it may be that the tuning is not turned off. However, due to the high requirements for sound quality of the mixer, the filter capacitor used in the power supply consideration circuit is larger, and some power will be stored after shutdown, so that some indicators will glow, and the lights will naturally go out with the chaos of the discharge time.

Show where the red light is on.

You check if the monitor button is pressed, you have to press it up to light up, and the main road fader has to be pushed.

Show which red light is going on and what's going on.

See if it's overloaded.

Numbers used to be displayed are no longer available.

The digital type is not displayed, because there is a problem with the CNC panel.

Check the CNC battery is OK.

The clip is lit to indicate that the peak clipping circuit of the amplifier has played a protective role. Protection occurs when the signal input amplitude is too large.

First confirm whether it is the mixer, the amplifier, and the wiring contact problem.

1. Turn off the machine, unplug the cable, turn off the volume potentiometer to the end, and then turn on the power amplifier to see if the light is on, if it is bright, it is a power amplifier problem, see that your machine has a lot of dust, clean it up first, the dust may cause a local short circuit. If it is not lit, turn on the loud volume to see if it will be lit and judge whether the fault is in front of the back.

2. After the power amplifier is fine, focus on checking the signal line grounding, and poor grounding will often cause overload protection. Plug in the signal cable, turn on the volume, and if the light is on, rotate the signal cable plug around.

3. Use other power amplifiers or computer speakers to try the mixer, the purpose is to confirm whether there is a problem with the mixer.

4. Switch the signal cable from the mixer to the power amplifier to the left and right to see if the left and right are balanced.

Check the amplification circuit from the volume potentiometer to the output.

This electronic thing needs to be looked at step by step.
