Rarely can we ever experience perfect conditions with, well anything, we do. We usually experience far-from-perfect conditions more often than not when putting on large events with all types of variables that require to return together. There might not be an ideal spot for your speaker on the small indoor stage, or it starts raining during your park event and therefore the only place for a speaker is under a tent during a less-than-ideal location.
While these are obviously things out of our control, there are certain things we will do in order to maximise your sound system’s performance.
We’ve talked about the way to found out your speakers on a stage during a previous blog post, so let’s cover another component: the way to hold your microphone, properly.
Seems pretty basic, right? you’d think so, but how many times have you ever seen someone holding a mic with their thumb over the top of their microphone? Or worse, their entire hand?! While it’s going to cause you to look “cool”, it’ll actually ruin the dynamics of the microphone and the way it had been designed to perform, possibly leading to , dun …. feedback!
Holding a microphone too low can cause similar issues. Generally speaking, the antenna for the microphone transmitter is found at the bottom of a microphone, an equivalent place you’d find the cable connected during a wired mic.
So if you set these two tips together then the sole remaining section left to carry on the microphone is within the middle.
How Much Movement is possible With A Handheld Microphone?
Holding a handheld mic (rather than speaking into a mic on a mic stand) comes with the liberty to maneuver around. Let’s discuss some general guidelines for moving around with a handheld microphone.
In order to stay a uniform microphone signal, it’s imperative to stay the microphone pointed at your mouth and at an unchanging distance and angle. So once you turn your head, move the microphone relative to your head turn, and vice versa!
If the microphone is wired, caution should be taken to avoid tripping over the audio cable. Wireless microphones are often utilized in presentations for improved user experience and safety.
Avoid stepping ahead of the loudspeakers (in an edge where the speaker points toward the highest of the mic). This poses an enormous risk for the awful sound of microphone feedback.
Feedback happens when a mic captures sound emanating from the loudspeakers, which sends more signal to the loudspeakers and thus more to the microphone. This loop stacks up quickly and therefore the system overloads, resulting in a terrible squeal from the loudspeakers.
The last guideline to the touch on has got to do with the range of a wireless system.
Unless the presentation takes place over a mile-long stage, this probably won’t be a drag . However, it’s worth noting that wireless microphone signals will only travel thus far from their receivers before they begin losing signal strength and ultimately cutting out.
It’s also imperative that you simply find a wireless frequency with no interference during which to work .
The Microphone is a few Distance From Your Mouth
Holding the mic beyond your mouth will reduce the danger of plosives for an equivalent reason. The larger distance between the mouth and capsule allows plosive energy to dissipate before hitting the mic capsule.
If you happen to note your voice “popping” on the microphone, try readjusting the microphone angle and maybe increasing the space between the mic and your mouth.
It’s not the top of the planet if there are plosives within the mic but they will become annoying. If perfection is being strived for, knowing these techniques will work wonders!
I wanted to say a couple of more details about the standard cardioid polar pattern of “presentation microphones.”
The cardioid polar pattern is that the commonest directional microphone pattern. The diaphragm is hospitable external instantaneous sound pressure on each side .
Here’s a visible 360º representation of the cardioid polar pattern. The further out the pattern line is, the more sensitive the mic is, ideally (on-axis/0º is at 12 o’clock):
