        Stage lighting and audio commonly used knowledge
        Date: Publisher:

        1. The device housing has a charging phenomenon check sequence
        The equipment casing is charged - the power supply line is damaged - the 
        line phase is correct - the equipment is grounded correctly - the voltage is 
        correct
        2, the sound system is not enough volume
        Insufficient device volume - Is the line level setting of the amplifier and 
        the speaker correct Is the speaker cable connected firmly Is the phase of 
        the amplifier and the speaker consistent Is the equalizer attenuation 
        amplitude appropriate Is the control level of the compressor limited
        3. Resonance and feedback occur in the sound field
        Resonance and Acoustic Feedback - Check if there is a peak in the room 
        frequency response - Is the room structure and decoration reasonable Is the 
        crossover point and bass gain reasonable Is the room reverberation time too 
        long
        4, generate interference noise
        The sound system has noise - dimming interference - whether the sound and 
        lighting power supply are separate - whether the lighting power supply and 
        control lines are too close to the audio signal line - whether the silicon 
        box is too close to the audio equipment
        The speaker system is noisy—is the signal transmitted properly—whether 
        the shielding of all signal lines is appropriate—whether the signal is 
        grounded correctly—the power phases of all audio devices are consistent
        5, the light is out of control
        The light is out of control - the controller's program is correct - the 
        address code of the luminaire is correct - the control line is connected 
        correctly - the shielding of the control line is bad or interfered - whether 
        the limit adjustment of the luminaire is appropriate - the light supply 
        switch is in good contact
        6, the lamp of the computer light is often damaged (750 hours)
        The bulb is fragile—whether the installation is secure or not, whether 
        it is contaminated with dust and moisture—whether the bulb is well cooled— 
        whether the voltage is normal—whether the power switch is frequent
        7, the video image is not normal
        Video image is not normal - whether the program format is correct - 
        whether the device casing is charged - whether the signal shielding is 
        affected by high level - whether the projection tube is normal - whether the 
        performance of the liquid crystal projection lamp is poor
        8, the wireless microphone sound is unstable
        Unstable sound—whether there is a high-frequency interference source in 
        the system—is the antenna connection correct—is the receiver fine-tuned 
        correct—the number of microphones is excessive—the microphone battery is 
        low.
