1) As a general guideline, it can be said that dynamic microphones are best suited for live sound work, and that condenser microphones are more suited for use in a recording studio. What do you think? Give technical and practical reasons for why this may, or may not, be a valid statement (include diagrams if necessary).
Dynamic Microphone
Dynamic microphones are the most common microphones used in live sound work/live performances. They are made of a Diaphragm, a magnet and a copper wire. The dynamic microphones are good because it can handle loud sounds, and it can be used for hours, it works fine with loud sounds and the Dynamic microphones doesn't need external power for it to work but the Dynamic microphone has to be connected to a pre-amp because it has a low output level.
The design of the dynamic microphone is really simple but it has a really strong material because if you drop it, it wont completely break into pieces. Dynamic microphones are usually cardioid or hyper cardioid which means they will only capture sounds from on specific direction.
Condenser Microphone
Condenser microphones are usually found in recording studios and different front the dynamic microphones, they are more sensitive, have a higher output level than the dynamic and have greater high frequency response giving a clear sound for the recording. Different from the dynamic microphone, the condenser microphone requires external power (phantom power) so that's why this type of mics are usually found in recording studios, because using them in a live performance would not be a good idea.
One of the bad things about the condenser microphone is that they are not ship at all and they are fragile and can break easily so that’t why you need to be careful when setting it up and while using it.
2) What are the three main polar patterns found on microphones?
Describe the differences and give examples of how each could be used (based on your own experiences if possible).
There are three different main polar patterns found on microphones and three of them, captures the sound in different ways, and they are:
Omni - The Omni is very different from the cardoid and the Bi-Direction, and the reason why is because it captures sound from all directions, front, back and sides. One good example of this microphone being used is when there's a group of singers performing together, best known as choir because not everybody can have their one microphone to sing on it so the Omni will be the best choice, because it will pick up all the choir singers and instruments.
Uni-Directional (Cardoid) - The cardoid which has the shape of a heart can only capture sounds from on direction, so something like a vocal line because the singer only sings in one direction which will be where the mic is. They'd be found in recording studios.
Bi-Directional - The Bi-directional which has the shape of an 8 can capture sounds from both front and back of its diaphragm and captures two focused sounds with some ambiance. This polar pattern is not really used like the other two. They can be found in a recording studio or while someones having an interview, because we'd capture both voices.
3) Dynamic and condenser microphones are the two most commonly used type of microphone found in the studio. Can you name any other types? Include their basic technical features and how, or why, they might be used.
Shotgun Microphone - The shotgun is a different microphone and usually used in films, interview, TV stuff and video production. They are really good to capture the frequencies the human voice produces. Different from the other mics, this microphone has a different shape because it is a long, cylindrical microphone and with microphones people normal hold them with their hands but this one will be attached to a long metal pole and the person holding it will have to follow the actor/actress if it's being used in a movie or just staying still if it's in a interview, the person holding it can't be more than three feet away or the audio will sound distant and they need to hold it high above the person's head where it doesn't appear on the cameras.
With this microphone, you won't have problems capturing the sound you need if you're outside and for example it is windy, because you can still capture the sound you need and the reason why is because this mic has a special fur material which preventing the wind, rain, etc from intruding the sounds/audio you want to capture.
4) Give suggestions as to what you might use the following microphones for and explain your answer:
Audix D6
The
Audix D6 is the most common microphone used in recording studios or live recording environments. The D6 is used to pick up the bass drum on a drum kit, it picks up a clean attack sound of the kick drum. The D6 has also a Uni-directional pick up pattern which means that the mic will only pick up a focused sound, so you need to put it in the right place so it picks up the right sound.
SE Electronics Titan
The SE Electronics Titan are the most large-diaphragm condenser microphones which are great choices if they are being used in a recording studio to record a singer or an acoustic guitar. The Titan provides a clear sounds of vocals, it doesn’t distort and it will pick up any sound, it doesn't matter if the singer sings high or low.
Microtech Gefell M300
The Microtech Gefell M300 are the best choices for recording instruments, for example, if you use it to record an acoustic guitar and put one of the mics pointing directly at the neck of the guitar and another one pointing directly at the body of the guitar you will get the sounds effects of the guitar when is being strummed or the fingers moving up and down. The M300 can be used in recording studios and also in live performances.
5) When using microphones, why is a mic pre-amp necessary? What features would you expect to find on a professional pre-amp (either standalone or as a part of a mixing desk)?
A pre-amp is necessary for a microphone because it gives to it a boost, because the output of a microphone is very low and without the use of the pre-amp, the microphone can't be heard. On a pre-amp, you can add reverb, it can add tone, change the EQ and change the gain.
