SHURE SH680 Wired Microphone – replica
If the microphone head is covered by hand or the microphone is aprosched to the speaker, a howling sound may be generated this phenomenon of howling is caused by the microphone picking up the sound output from the speaker, To prevent this, first decrease the volume, then place the microphone so that it is not pointed to the speaker and that there is a sufficient distance between the microphone and speaker
Do not store microphone in a place with high temperature or humidity.
The optimum distance between the microphone and mouth is from 5 to 10 centimeters. If the microphone is too close to the mouth, the sound may be unclear with too-much enhanced bass(proximity effect) or may be uncomfortable to ears with pop generated every time the singer breathes in and out.
