2. The frequency adjustment problem of the illustrated balancer: There are three kinds of spectral wave patterns of the swallow-type mountain-type wave type. The above waveforms are all imagined by the tuner. In fact, it is not the waveform of the sound field practice requirements. We know that The ideal sound field frequency characteristic curve should be relatively flat. If the artificial sound field frequency characteristic curve is artificially imagined, the unbelievable result is counterproductive.
3, the limiter adjustment problem: it is common to do the display basically does not work and the role of excessive reaction. The former can make use of it, the latter will bring about a serious impact on the dynamics of the system, as the sound can not be emitted, the obvious performance is that the stronger the accompaniment sound, the natural weakening makes the singer feel at a loss.
4, system level problem: First of all, the power amplifier flexibility control switch is lack of open, and secondly the system does not make zero level adjustment. Sometimes the mixer channel pushes a little bit of output, which can affect the dynamics and distortion of the system.
5, bass signal disposal: the first type does not do electronic crossover with full frequency signal directly to the amplifier to promote the speaker; the second does not know where to extract the bass signal from the system for disposal. Assume that the full-frequency signal is not used for the electronic crossover to directly push the amplifier to the speaker. Although the speaker has sound and does not burn out the unit, it is unbelievable to send the full-range sound in its low unit; but if the signal is obtained from an inappropriate position in the system, On-site control brings unnecessary trouble.
6. Effect loop disposal: The post signal of the fader should be taken to prevent the uncontrollable effect from causing the microphone to scream and return to the conditional occupied one channel, so that the debugging is more convenient.
7. Line connection process: The common system communication interference sound is that the line connection process is not formed well, and there are certain imbalances in the system and the unbalanced to balanced connection must be connected according to the specifications. Also don't use inferior connectors.
8. Control problem: The mixer is the control center of the system. Sometimes the high, medium and low EQ balance on the mixer is equally enhanced or attenuated. The system is not adjusted. The system needs to be re-tuned. Taiwan's EQ.
Common problems and solutions for audio engineering installation
[Audio Network Information] 1. Signal distribution problem: In the case of several sets of speakers in the sound field, a balancer is often used to distribute signals to multiple amplifiers. But at the same time, it may be that the power amplifiers and speakers of different brands are mixed together, so that the distribution signal brings many problems, whether the impedance can be matched, whether the level distribution can be balanced, whether the power obtained by the speaker is normal, and the balance is very good. It is difficult to adjust the frequency characteristics of the sound field and the speaker.
