How to do the test report? Why do you need to do product inspection? Third-party testing institutions provide product testing services in various industries, and there are many cooperative laboratories across the country, mainly serving companies, enterprises, individual businesses, universities and scientific research.
Testing process
1, sending samples
2, checking requirements
3, targeted quotation
4, both parties determine, sign a contract, start
the experiment5, complete the experiment: the testing cycle (can be expedited) will be changed according to the sample and its testing items / methods, you can consult the engineer
6, issue a test report, and provide post-service.
Both professional audio equipment and stage lighting equipment should be well maintained. Fault lines and equipment should be repaired in a timely manner to avoid accidents. So how do you check if the audio equipment is suitable? Below, the editor will share with you some of the repair tips, hoping to be helpful to everyone
1. Inspection sequence for charging phenomena in the casing of stage audio and lighting equipmentThe electrical inspection sequence of the equipment casing should first check whether the power cord is damaged, whether the phase of the circuit is correct, whether the equipment is grounded, and whether the voltage is correct.
2. In the case of insufficient volume check for professional audio systems
Under normal circumstances, if the volume of professional audio systems is insufficient, it is necessary to promptly check whether the amplifier and speaker circuit level settings are correct.
. Secondly, it is important to understand whether the speaker wiring is securely connected. And the amplifier is in phase with the speaker. Is the amplitude of the equalizer decaying within the normal range, and is the initial control level of the compressor appropriate
