1. Check sequence for electrified phenomenon in equipment shell
The housing of the equipment is electrified—whether the power supply line is damaged—whether the phase of the line is correct—whether the equipment is grounded correctly—whether the voltage used is correct
2. Insufficient sound system volume
Insufficient volume of the equipment—whether the line level setting of the power amplifier and the speaker is correct—whether the speaker wire is connected firmly—whether the phase of the power amplifier and the speaker is the same—whether the attenuation amplitude of the equalizer is appropriate—whether the start control level of the compressor is correct
3. Resonance and feedback in the sound field
Resonance and acoustic feedback occur-check whether the room frequency response has peaks-whether the room structure and decoration are reasonable-whether the crossover point and bass gain are reasonable-whether the room reverberation time is too long
4. Produce interference noise
The sound system is noisy-dimming interference-whether the audio and lighting power supplies are separated-whether the lighting power and control lines are too close to the audio signal line-whether the silicon box is too close to the audio equipment and the speaker system is noisy-whether the signal transmission is reasonable-all signal lines Whether the shielding of the audio equipment is appropriate—whether the signal grounding is correct—the power phases of all audio equipment are consistent
5. The lights are out of control
The light is out of control—whether the program of the controller is correct—whether the address code of the lamp is correct—whether the control line is connected correctly—whether the shielding of the control line is bad or interfered—whether the limit adjustment of the lamp is proper—whether the light power switch is in good contact
6. The bulbs of computer lights are often damaged (750 hours)
The bulb is easy to break-whether it is installed firmly, whether it is contaminated with dust and moisture-whether the heat dissipation of the bulb is good-whether the voltage is normal-whether the power switch is frequent
7. The video image is abnormal
The video image is abnormal—whether the program format is correct—whether the equipment casing is charged—whether the signal shield is interfered with by high level—whether the projection tube is normal—whether the performance of the liquid crystal projection bulb is poor.
8. The sound of the wireless microphone is unstable
Unstable sound-Is there a source of high-frequency interference in the system-Is the antenna connected correctly-Is the receiver fine-tuned correctly-Is the number of microphones excessive-Is the microphone battery low.
