1. The sound of wireless microphones in professional audio equipment is unstable

If the wireless microphone is unstable, first check the cause of the unstable sound, which is caused by high-frequency interference sources in the system, or the connection error of the antenna, the fine adjustment of the receiver, the battery power of the microphone, etc.

2. Inspection of video images in audio and video systems
If the video image is not normal in the professional audio equipment, first check whether the program format is in the correct range, whether the device casing is charged or not, and secondly check whether the signal shielding is susceptible to high-level interference. It is better to check whether the projection tube is in the normal range, and there is no problem in the performance of the liquid crystal projection bulb.
Realizing the interaction between the environment and the sound is also a skill that cannot be ignored for audio device users. Tuning and enjoying music also requires a correct listening environment.  Sinray continues to innovate, gradually simplifying the complicated system configuration in the past, and launching its own flagship product to meet the needs of users, making the entire conference room sound reinforcement system simple and powerful, more convenient to operate, and more perfect.

1. Checking the sequence of insufficient volume in the professional audio system

Under normal circumstances, if there is insufficient volume in the professional audio equipment, it is necessary to check whether the line level setting of the amplifier and the speaker is correct, and then understand whether the speaker cable connection is firm and whether the phase of the amplifier and the speaker are consistent. Is the equalizer attenuation amplitude in the normal range? Is the control level of the compressor appropriate?

2. Inspection method for out of control of lights
When the light is out of control, it is necessary to check whether the controller’s program has any problems. Is there any problem with the address code of the lamp? Is the connection of the control line correct? There is also a need to check whether the control line is shielded or not, and the limit of the lamp is limited. Whether the adjustment is appropriate, etc.
3. Computer light bulb damage check
In the stage sound lighting, it is easy to appear that the light is easy to break, so if there is a problem, it is necessary to check whether the installed light bulb is secure, whether it is contaminated with dust and moisture, and whether it is to check whether the heat dissipation of the light bulb is in the normal range. It is better to check whether the voltage is within the normal range and whether the power switch is used too frequently.

Here is Stage Chain Electric Hoist Wholesaler talking about 8 Tips Help You Solve The Stage Equipment Failure In Minutes.
If you have any idea about Small Size Aluminum Electric Hoist, welcome to contact us and discuss.
As we all know, the normality of the stage sound and light directly affects the effect of the performance, so both professional audio equipment and stage lighting equipment need to be maintained and maintained, and the faulty lines and equipment should be repaired in time to avoid accidents. appear. Today, sinray Technology will share 8 tips for you to quickly solve the stage sound and lighting equipment failures and solve the on-site problems in minutes.

1. The order of the stage sound lighting equipment housing has a charging phenomenon
The order of the electrical inspection of the equipment casing is first to check whether the power supply line is damaged, and secondly, whether the line phase is correct, and then to know whether the equipment grounding and voltage are correct.
2. How to check the resonance and acoustic feedback in the sound field
If resonance and acoustic feedback occur in professional audio equipment, first check whether the room frequency response has peaked and whether it is necessary to check whether the room structure and decoration are reasonable, and also check whether the crossover point and bass gain are reasonable. Whether the room reverberation time has been too long.
3. Inspection method for generating interference noise
If there is noise in professional audio equipment, first check the dimming interference, whether the audio and lighting power supply is disconnected, and then check whether the lighting power supply and control circuit are too close to the audio signal line, and there is no silicon box. The audio device is too close.
Under normal circumstances, there is noise in the speaker system, which is usually caused by unreasonable signal transmission. Therefore, when there is a problem with the shielding of the signal line, or the grounding of the signal is not correct, noise interference is likely to occur.

It can be seen in some concerts, theaters and various mobile stages. On the stage, the stage electric hoist can provide a variety of beautiful effects on the stage. This is just one of the small advantages of the stage electric hoist.

The China Stage Chain Electric Hoist has the following eight advantages:

Advantages 1. Flexible to use, can be used upside down, or installed as self-climbing. Can be arbitrarily matched according to the use environment and occasions.

Advantages 2. The China Stage Chain Electric Hoist is generally used by group cranes. Due to the high speed, the motor speed requirement is very high, requiring no error or little error.

Advantages 3. The deceleration of the stage electric hoist is decelerated by the cycloidal needle without any noise and strong braking.

Advantages 4. The appearance of the gourd head is frosted and sprayed, the color is black, which is more beautiful, does not reflect light, and does not affect the stage effect.

Advantages 5. The core of the stage electric hoist is the motor. The motor uses 60 矽 steel sheet, which has slow heat production, high power and long working time.

Advantages 6. The chain is fully enclosed, which ensures smooth chaining, dustproof effect, and long service life.

Advantage 7. Use a wire-cut chain guide.

Advantages 8. The gear material is 40 chrome, which is ground and therefore finer and less noisy.

The Stage Machinery is special mechanical equipment for the stage performance, which is used to create special effects in the live performance. In fact, as early as the 5th century BC, when the Greeks invented Deus ex machina (Latin: “God of Machines”) Live performances have already been used on stage machines, and the actor is lowered from a height to the stage by a crane. The Romans also introduced these devices in detail, adding traps (similar to the lift stage) and underground pumping systems to perform water performances on the outdoor stage, while in some mysterious plays of the Middle Ages, similar to WIA and lifts were used. Stage machinery for mysterious appearances of demons and angel characters.

▲ early stage machinery
Stage machinery can be divided into two categories: permanent machinery, that is, equipment that is part of the theater structure; and temporary machinery, that is, equipment that enters the theater and stage and is used in conjunction with specific production. The use of a large number of stage machines enhances the visibility of live performances and promotes the diversity of live performances, which is the future trend of stage performances.
Stage mechanical control system
The control system is an important part of the live performance stage machinery. The control system mechanically moves, tilts, and rotates the screen, set, and performers on the stage to bring an ever-changing performance to the scene.
Different from the early manual control system, the stage machine has realized intelligent CNC, PLC programmable control system and servo control system are often used in today’s stage machinery control. The PLC programmable control system and the integrated technology of machine, electricity, and liquid realize the movement of stage lifting, translation, telescopic, etc., so as to achieve the coordinated change of stage and dance, actors, scenes and lights.
A servo control system is a feedback control system used to accurately follow or reproduce a process whose purpose is to accurately track the input by the mechanical displacement (or corner) of the output. The main indicators to measure the performance of the servo control system are reflected in the system accuracy, stability, response characteristics, and operating frequency, especially in terms of bandwidth and accuracy. It is able to achieve precise movements on the stage, screens, actors, etc., perfect for performances.
Stage lift
More and more stages are designed to add stage lifts, which have a variety of functions such as lifting, rotating, tilting and so on. It can be used to quickly switch scenes, change stage shapes, create special stage effects, and meet the needs of dance design and choreographers who create exciting effects and dramatic displays by enhancing artists, band equipment and props. It is important.
The stage lifts can be seen everywhere in the current performance scene. Whether it is a large concert, a conference or a theater, you can see the stage lifts. It brings more possibilities to the performance and is an indispensable part of the stage machinery.

Stage Electric Chain Hoist plays an important role in stage construction and stage performance. Among them, the chain hoist is used for stage construction and lifting of objects and can lift, position or pull the load from almost any angle even in a narrow space. It can keep workers safely away from the load during operation and can effectively prevent accidents and injuries.
Stage Electric Chain Hoists are more used for stage performances, such as the ups and downs of large screens, the lifting, and tilting of lamps and stage props, etc. The CM Lodestar electric chain hoist like COLUMBUS MCKINNON has excellent performance and operation. Quiet, high-load cycle, first-class safety features, often used in large concerts and event performances.
Robotic Arm
Mechanical arm, robot, and other machinery are more applicable to industrial manufacturing, intelligent machinery and other aspects than the application on the stage. But this does not prevent the robotic arm from becoming the new favorite of stage machinery in recent years. The robotic arm can quickly rotate large screens on the stage, move the props on the stage, and even interact with the performers.
The use of robotic arms on the stage is an innovative stage performance that adds more futuristic and visibility to live performances.
The Stage Performances are more and more diversified, including the lights, indoor drones, 3D Mapping, holography, etc., all of which are constantly injecting new blood into the stage, bringing together the audio-visual feast again and again.
