TYPES OF CONNECTIONS AND CABLING USED IN THE STUDIOS

Balanced and Unbalanced Connections:

The balanced connections uses three conductors; one for the positive and one for the

negative phase of the signal and one for the ground. It protects it from humming and

interference.

The unbalanced connections use two conductors; one for signal and the other for ground

but they are likely to hum and interfere with the connectors; these are usually used by the

consumers.

Digital Connectors: Digital Connectors are also known as audio connectors are electrical

connectors that are designed and used for audio frequencies.

Computer Connectors: Computer connectors are part of the cable that would be plugged

into the port or the interface to connect to a device to another. It has a male side which

would have the pins and the female side would have holes for the male part to insert.

Patch Leads: Patch Leads groups all of the inputs into one location on the Mesa. For

example with keyboard instruments it can be connected without going around the rack or

the instrument and trying to find the right jack.

DEFINITION EXPLANATION OF STUDIO EQUIPMENT/SIGNALS

Audio Interface: Is an external hardrive unit that is connected using a USB cable or FireWire.

It takes all various audio inputs and converts them to digital data. Its like a soundcard

where it handles all the audio input and output signals.

Signal Levels: They can be found in audio recording or a radio frequency communication

where it measures the level of signal thats being received. It relates to signal-to-noise ratio

which measures the radio between random signal level and noise and it can be used to send

information.

Direct Injection: Direct Injection or DI box is a device that is used in recording studios which

is connected to a high-impedance, line level, and unbalanced output signal to a low-

impedance microphone level balanced input with a XLR connector. It can be used on the

electric guitar or bass to mixers mic input. It can match, balance and either active buffering

or passive impedance matching and it can minimize noise, distortion and ground loops. It

can take high impedance, unbalanced signal and converts them to low impedance which

would balance the signal. For it to work with an instrument it needs to be connected with an

XLR input.

Patch Bay: Patch Bay is a device that collects the inputs and outputs of all the instruments

which connects all the equipment in the studio. It can be used for recording and broadcast

studios. They route the connection of the microphones/preamps, compressors, EQ,

amplifiers and other devices. The short patch cables for the jacks are put in the front; they

also have jacks at the back of the patch bay to connect hardware permanently. When thejacks are inserted at the top they are routed to the outputs and the bottom are routed to

the inputs.

VU Meter:VU or volume units measure the volume of a source of an audio. It doesnt tell

you about the loudness of the sound through the speakers but it represents the volume of

sound thats recorded off of tape. Some VU meters have a needle bouncing but others have

a series of red and green lights. This means the display changes according to the volume of

the incoming sound. For example when recording audio, the needle has to be pointing

straight up. It would bounce both a little below and a little above.

Noise Gate: Noise gate gets rid of unwanted noise that is audible when the signal level is

low. It is useful to remove background noise, crosstalk from other signal sources and also

lowers the humming sounds. This works by allowing signals above the threshold level to

pass unchecked while reducing signals below the threshold level. It gets rid of the lower-

level parts of the signal, while it allows the necessary parts of audio can be used.

Parametric EQ: Parametric EQ/equalizers are multi-band variable equalizers that allow us to

control their three primary parameters which are the amplitude, centre frequency and

bandwidth. Each band is controlled and the centre frequency can be shifted and bandwidth

can either widen or narrowed. They are also used in sound recording and live sound

reinforcement. Another option of the parametric equalizer is the semi-parametric equalizer.This controls both the amplitude and the frequency but uses a pre-set bandwidth of the

centre frequency.

Shelf EQ: Shelf EQ can either boost or reduce the energy at the set frequency. For example ifthe frequency has maximum boost will be the most extreme frequency between 20 kHz for

a high shelf and 20 Hz for a low-shelf. The turnover frequency would have 3dB less boost

than the extreme frequency if the EQ was set to its maximum boost.

Outboard Equipment: The outboard equipment alters how a musical instruments sound. It

can be used for live performances or recording studios. Its separates it from the effects

applied by using the mixer or the audio interface. It has the typical early units like the

Wah-wah pedal to produce phasing effects for the electric guitar. It can be also used on

vocals using an echo effect or pitch transformation of the singers voice. Its designed to

compress or expand the duration of sound and alters the speed of length of the original

sound.

HEALTH AND SAFETY FOR WORKING IN THE STUDIOS

The following rules to apply to when working in the studios:

You must carry out a noise risk assessment and assess the risk Then write, distribute and monitor a noise policy for the studio Control, reduce and monitor peoples exposure to noise in studios Performance noise should be kept down irrespective of the balance of the mixing

desk

Plan sessions and access to studio areas Clarify the responsibilities and confirm arrangements Ensure people have a hearing health check and provide hearing protection if needed

in certain places

Note down who exposes noise and provide feedback when needed Reduce monitor speaker levels in the control room Position people and equipment to avoid accidents Provide training, information and instructions to musicians and techies to be aware

of their own problems

TYPES OF MICROPHONES

There are different types of microphones that are used in the studios. These are:

Dynamic Microphone: It has an advantage of the electromagnetic effect. When the magnet

moves past a wire, the magnet will induce its current to flow in the wire. Its diaphragm can

move either a magnet or the coil when the sound waves hit the diaphragm. An example of

a dynamic microphone is the F14 Audix-Bass Drum-Dynamic mic (large diaphragm).

Condenser Microphone: Its a capacitor with one plate moving in response to the sound

waves. This type of microphone would need a small battery to provide a voltage across the

capacitor at times. An example of a condenser microphone is the 3 neumann Mics- 1 large

diaphragm and the F15 HIGH HATS-CONDENSER MICS

Pencil /Overheads Microphone: These are used in sound recording and live sound

reproduction to pick up ambient sounds and the overall blend of the instruments. They are

mainly used to record a full drum kit as a stereo. When positioning them they are angled at

an XY 90 degree. An example of overheads microphone in the studio is the 2 pencils

condenser (LM184)-overhead.

HOW TO ROUTE SIGNAL FROM THE LIVE ROOM TO THE DESK THEN

TO THE COMPUTER VIA AN EXTERNAL COMPRESSOR?

Routing signal from the Live Room

Inside the Live Room, the condenser microphone is set up and one end of the XLR is inserted

in the microphone and the other is inserted into the stage box at its chosen channel input

which is input 1.

3 DISTINCT STUDIO ROLES

Mastering Engineer Job Role:

To edit songs in proper order Sorting out the spaces between songs Crossfading between songs Fading in and out songs to a perfect digital silence Fading out songs earlier or fading in songs that have weaker starts Going through each songs individually so it sounds the same as the others in terms

of volume and EQ

Adjusting volume of sections of a song e.g. the guitar solo for the intro and acousticguitar are too loud

Doing dynamic process so that the finished production plays back at the propervolume

Doing dynamic processing so the lower-powered playback systems doesnt distortthe medium-loud levels

Sorting out EQ levels to make changes in the mix like bringing vocals up and bassdown

Removing clicks, pops and glitches that occurred during the recording. Editing two or more mixes of the same song to assemble the perfect mix. Editing the song in sections to either shorten it repeated or lengthens it.

Adding ambience to broaden and deepen the stereo field.

Reverse or replace unpleasant words for a radio version of the song Adjusting the EQ so it matches the major label releases.

21/28

Record Producer Job Role:

They help the artist by coaching and working with them to get the recording thatthey need.

They have to assist the audio engineers with the mixing and recording process They also carry out other job roles like an arranger, composer or songwriter so they

can be fresh ideas to the tracks.

They take full responsibility of the creative mix. Usually the laise with the soundengineer who would focus on the technical aspects of recording and the producer

focuses on the overall projects marketability like ensuring that the business is

successful and they kept within their budget.

At times they help find contacts to help promote the artists music and advice theyon publishing and royalties and other aspects of the music industry.

They work in different ways e.g. some could take full control of the project; otherswould work with other artist, musicians and technicians as a creative partner to

produce the best track possible.

They oversee all the process of the recording session from the planning of thesessions to the finished product.

They have to provide instruments, scheduling studio time, handling funding, costsand negotiations

They need to create quality sounds that match both the musicians and producersplans.

Composer Job Role:

They create music that can be performed for voices, groups of musicians or soloists.Their compositions can be done in different styles such as opera, blues, big band and

soul

They also create music for films, radio, computer and any other media.


22/28

Some composers may use electronic tools like computers and synthesizers to helpthem write. They need to be aware that there are possibilities and limitations of

each instruments and human voices.

If they working for film productions they need to be able to compose in differentstyles and improvise and create themes to meet deadlines. They need to listen toinstructions and translate their vision to musical terms.

Develops the pattern of harmony and applying knowledge of music theory Transcribe or records musical ideas to notes on a scored music paper. Creates original music They use synthesizes for the melody of the musical scores for the band They file appropriate compliance reports with regulatory agencies

PROCESS OF DRUM RECORDING

1) Setting Up the Drum Kit:

The drum kit is already set up. So we just need to mic it up. We get all the drum microphones from the cupboard like the F14 Audix, LM184 First we the kick drum-using the F14 Audix and placed it inside of the bass drum and then

connected it with an XLR and put it into the stage box in input 1.

Then we did the snare-using the Shure SM57 dynamic and we plugged it in the stage box ininput 2.

Then hi-hats- using the F15 Audix and positioned it on the tip of the hi-hat and plugged itinto the stage box in input 3.

Overheads- using the 2 pencils condenser (LM184) - these we positioned at an XY angle overthe crash symbols and then they plugged into the stage box in input 7 and 8.

2) Routing and Sorting out Signals: As you seen from the diagram of how to route signal fromthe live room to the compressor we did this process again. Then we are going to sort out the

channels on logic. We also sent signals from the patch bay to the computer. During this

process we had a bit of difficulty using the patch bays because we kept putting the patch

leads in the wrong inputs.

4) Recording and SamplingMy group task was to record a drum kit using 3 channels at the same time. We experiment the

overheads and the kick drums by recording them.

Then we did some sampling use all the parts of the drum kit. All had their own channel so that it

would be easy to edit on if there were mistakes made after the recording. Also we did a full run

through as a full drum recording as well as just hitting each part of the drum as a signal test. Also

added vocals from our tutors.

We had to do a multi-track by testing out the mics for our drum recordings.

We also did Signal Test with different instruments-we did a least 2 takes with each instruments and

then added some vocals (which our tutors volunteered to do).

We also did drum samplings and made our own library of samples
