Unit 9 Key Properties Condenser Microphone Dynamic Microphone Polar Patterns / Directional response in Microphones Definition & Instrument Use Advantages Disadvantages The condenser microphone is also very sensitive, preferred for vocal recordings. called a capacitor microphone because it uses a capacitor. The microphone requires power from a battery or external source. very sensitive – could pick up background noise. The dynamic microphone uses a wire coil and magnet to create the audio signal. need to use a mic preamp. Doesn't need a battery or power supply and they are durable as well as fairly inexpensive. Polar patterns / Directional response in Unidirectional Picks up sound Omnidirectional is a more predominantly from one direction. general and unfocused type Microphones are how well the microphone picks up sound from different directions and Bidirectional there are different types that pick up sound Picks up sound from two opposite directions good for around a certain area. duets. of polar pattern which mean that you will need to know what type will be better for a.

Key Properties Microphones with Phantom Power Proximity effect of Microphones Frequency response of microphones Definition & Instrument Use Advantages Disadvantages phantom power can just be labelled as ‘phantom’, and occasionally ‘+48 v’. It is a direct current of 48 volts supplied through a microphone cable. it powers the mic with the same Microphones that operate on voltages from 9 – 48 lead that is used to record so volts. These mic’s don’t there is less wires needed. Proximity effect is a change in the frequency response of a mic having a directional pickup pattern. proximity effect can result in a boost of up to 6 d. B adds a sense of depth to the voice increases the bass or low frequency's. unidirectional do not exhibit proximity effects. is the amount of gain that a microphone produces in response to all the various frequencies. there is more than one type of frequency response there's tailored which allows you to enhance a sound source and there's flat which is better where the sound source has to be replayed without changing. because of proximity effect, if a sound source is more than a few inches from the capsule it can have less bass. get benefit with higher phantom voltages.

1. 2 Sound source How will a Microphone make life harder for the performer / Audience Frequency (Low / High frequencies or a mixture) Input signal (will the volume remain the same? ) having a microphone in your hand a mid ranged to high are good as an actor limits you to one hand. frequency's. The input signal won’t stay the same because the actor might be shouting or whispering at different points. All have to surround the microphone. A mid ranged frequency's is good. There could be a section of high pitched signers and a section of low pitched singers can be too loud for the people up front or to quiet for the people in the middle. any frequency is good depending on what the music is. You can expect some dynamic changes depending on if everyone is singing at the same time. Kick Drum could be awkward to set up or could get background noise. for a kick drum a high mid range frequency is good. you can expect some loud and soft dynamics from different styles of playing as well as if there any effects used Snare drum could use the wrong mic for the place microphone. like the kick drum a high mid range frequency is good. Some dynamics like drum rolls will be consistently loud. Actor Group of singers Amplifier (Gtr / Keys)

Sound source The best Mic Why this mic? What other Mics did you consider and why did you not use them Shure SM 58 microphone it is a good mic for vocals because it is unidirectional, has a pop filter and is £ 87. 00 Shure SM 7 B Dynamic Studio Recording Microphone it doesn’t have a pop filter and is £ 315. 00 Se Electronics se x 1 Vocal Pack Microphone It’s a condenser so in a large group it is a good mic but costs £ 115. 00 it is also good for instrumentals and has a pop filter. Qtx CCM 1 Studio Condenser Microphone although it is cheaper it isn't good instrumentals and doesn’t have a pop filter Shure SM 57, Sennheiser MD 421 It has a frequency response which suits the range of a guitar amp & because of it’s shape you can get it close to the speaker. Shure SM 58, they are similar but the shape of the grill on the SM 58 means you cant get as close to the speaker for the full bass AKG D 112, Audix D 6 The mic is designed to pick up low frequencies & handle loud sound sources. A condenser mic would pick up the low frequencies but might not be able to handle the inside of the drum very well. Shure SM 57 If you pick a model with a small size like the SM 57 you can get it close to the drum. A small diaphragm condenser would be more sensitive to bleed from other sources.
