Common problems and solutions in the use of stage lighting equipment!


Stage lighting and sound system common problem analysis and inspection methods, stage lighting and sound equipment are the key factors for the success of the performance. Therefore, we need to regularly inspect and maintain stage equipment such as lighting and sound, and maintain problematic equipment in time to avoid accidents. The following are common problems and inspection methods of stage lighting and sound equipment (for reference).

  1. Stage lighting and sound system

The order of the live inspection of the equipment shell: first check whether the power cord is damaged; secondly check whether the line phase is correct; finally check whether the equipment grounding and voltage are normal. Detection of interference noise in audio equipment. If the professional audio equipment has noise, first check the dimming interference and whether the sound and light power supply is disconnected. Secondly, check whether the lighting power supply and control circuit are too close to the audio signal line, and whether the silicon box is too close to the audio equipment.

  2. How to check the resonance and feedback of the sound field

If resonance and sound feedback occur in professional audio equipment, you should first check whether the room frequency response has a peak, whether the room structure and decoration are reasonable, whether the frequency division point and bass gain are reasonable, and whether the room reverberation time is too long.

  3. Check whether the volume of professional sound system is insufficient

Under normal circumstances, if the volume of professional audio equipment is not enough, you must check whether the power amplifier and speaker line level settings are correct. Secondly, it is necessary to know whether the speaker circuit is firmly connected, whether the phase of the power amplifier and the speaker is consistent, whether the attenuation amplitude of the equalizer is within the normal range, and whether the starting control level of the limiter is appropriate.

  4. Inspection method of lighting equipment in out-of-control stage

If the stage lamp is out of control, it is necessary to check whether there is any problem with the controller program, whether there is any problem with the address code of the lamp, whether the control line is connected correctly, whether the control line is interfered by bad signals, and whether the limit adjustment of the lamp is appropriate.

  5. Inspection for damage of Class 6 bulb

In stage lighting, because the bulb takes a long time to light up, and the temperature of the bulb is very high, it is easy to damage the bulb. Therefore, it is necessary to check whether the installed bulb is firm, whether it is contaminated by dust and moisture, whether the heat dissipation of the bulb is within the normal range, and finally check whether the voltage is within the normal range, and whether the power switch has been used frequently.

  6. Unstable voice of wireless microphone in professional audio equipment

If the wireless microphone is unstable, first check the cause of the unstable sound, whether it is the source of high-frequency interference in the system or the problem of equipment connection, such as incorrect antenna connection, receiver fine-tuning, and microphone battery power.
