A sound system of feedback suppressor several connection methods

Yuan hua chi

1, like equalizer and other peripheral equipment concatenated in the sound system, the advantage of this connection is: connection and simple operation, suitable for simple system. But the disadvantage is that: the connection method in the inhibition of microphone sound feedback is also affected by other audio signal feedback suppressor; And we put a feedback suppressor concatenated in the mixer's main output, that at this point the feedback suppressor can suppress the signal channel acoustic feedback, to other channels such as AUX output, the output of marshalling is not effective.

2, the use of the INS in the mixer channel insert/plug out of the interface will feedback suppressor concatenated in the corresponding channel, the advantage of this connection is: can adjust feedback suppressor, utmost don't affect other audio source. Defect is: using the method of the connection a feedback suppressor can control most mixer 2 channels, equipment is not fully utilized.

3, using the INS in the mixer marshalling insert/plug out of the interface will feedback suppressor concatenated in the corresponding marshalling tunnels, the advantage of this connection is: to make up into the organization of the microphone for centralized processing, also need not affect the other sound source. Disadvantage is: easy to produce wrong operation, such as: a mixer 1-8 road is a microphone, we put the 8-way 1-2 marshalling of the microphone in the mixer for centralized processing, but if 1-8 microphone in any way not carefully and make up to 3-4 marshalling, if three or four marshalling and no feedback suppressor, that at this time also might have an acoustic feedback. So to the mixer is understanding, and seriously only can use this method to operate. In total because this method can make full use of feedback suppressor, therefore also be connected by the most current methods.

4, if there are some marshalling channel mixer, no INS insert/plug out of the interface, we don't want to put the feedback suppressor concatenated in the main output channels, and think to centralized control over the microphone, that we can use a don't look too standard, textbooks do not have method, such as: a mixer 1-8 road is a microphone, we can put the microphone volume 8 road through the corresponding AUX sent to feedback suppressor, if be AUX5-6 channels. Through feedback suppressor again after processing flow back to the corresponding channel mixer, if be 23-24 channels. This connection method and a wireless connection, require AUX will send after setting in the pusher, also requires AUX5-6 in the 23-24 channels cannot be opened again, otherwise it will produce signal circuits; But the difference is 1-8 channel volume at this time cannot be included in any organization and the main channel, also is the main channel of L - R, marshalling channel 1 or 2, 3-4, 5-6... Single channel and so on the corresponding button don't dim down, let the eight channel volume of pure through the AUX5 - only 6 send out, and then after 23-24 road with mixer, the mixer again through the corresponding signal channel output. Such can also have very good effect, but it feels this way is a bit eccentric, but my point is always stressed: flexible and practical.

5, and another way is to use two electric mixer, a dedicated connection microphone, through feedback suppressor handle the volume again after input to mixer in the other one. The advantage is that the maximum to the centralized control the microphone, and completely avoid the interference with other sound source; Defect is: dedicated to the processing of microphone is usually small mixer, its quality is better than general big units, and function also is not rich, so on the processing quality may not be ideal; There is two mixer to operate some trouble, not skilled technicians is often make a fuss.
