Some context in the general 'room' level. Other noise has contributed to adaptions in sound design.
A good operator can hear if a mic has moved. This shows it is important to constantly be listening to the room to learn the mix and notice small changes.
The visibility of a mic is another factor to consider, hiding mics closeby still gives a good distance from the mouth.
Having lavs in the hairline gives a good consistent distance from the mouth to the mic. Due to the lavs being omnidirectional, having vocals in foldback speakers can cause many problems including feedback.
A con of this method is having sweat and hair products get into the mic.
A way of getting around this could be by adding handheld mics in on larger numbers. This allows the vocal to be in the foldback as handheld mics have a cardioid pickup pattern.
However, having a handheld mic on stage can ruin the immersive atmosphere and also limit the performer's movement with only one hand free.
In the tech rehearsal, setting levels, EQ and compressors where necessary.
The recommended method of attaching mics to performers is in the hairline, held in with micropore tape and hair clips. It is important to use micropore tape on the skin as it will not cause irritation.
Attach the pack at the waist in a belt, run the mic cable up the back to the head. Ensure there is enough slack to allow movement of the head.Â
If hairline placement is not possible, creating an ear hanger is another option.
Another option is using a lavalier mic attached to the costume. This results in distance between the mic and mouth changing.
Use micropore tape to secure the mic cable, not covering the capsule, taping with the head tilted forward. The main thing to be aware of is allowing enough cable length.
