Notes:

microphone is held by mic sand, has boom (lever at top)....onstage stands....need mic clip, allows mic to clip on to boom meaning mic stand

?xlr cable is a standered cable used with most microphones, has low inpedence? (how fast or slow signle travels inside a cable)

?low impedince cable has less signal loss

Female and male of xlr, female always goes into mike....you can wrap cable with clip on bottom of stand, for saftey

To roll up, make loop, spin fingers, memory is bad

XLR connecter end with a regular patch cord end, cord called quarter inch, usually high impeidence

Longer cable has both quarter inch connectors, long, high impedience

Female end and quarter inch end, has extra ring on quarter inch end (valence), used for headphones usually, will give you left and right signal

Hook in back of amp or speaker, called speakon cable, locks in place

RCA cables used for CD players, ipod adapters, (radio corperation of america), has left and right audio, sometimes video (yello)

Duel adapter, balenced quarter inch connecter,

Wind screen, goes over hand held recorder so it doesnt create wind things (noise?)

Banana clip, allows you not to have to use regular stereo wire, commenly used in back of amplifier

Balenced patch cable, used on patch bays

Connector for RCA (from RCA to big amplifier maybe)

Xlr to quarter inch patch balenced

TRS balence (tip ring sleeve)

Eighth inch jack, get left right signal, used mostly for small audio devices

Male RCA splits to two female RCA's

Split set of headphones, stereo on both sides

High z unbalced, low z balenced, converter that changes impeteince from high z to low z, impediance transformer

XLR male to male

Adapter that tells if outlet has ground

Converter from XLR to quarter inch, impediance converter

Direct box, quarter inch jacks on one side, XLR on other side

impedance converter, splits single so you can use on stage amps as monitors

Cable tester, tests if cable works or not

Pop filter, gets rid of explosive noise (while talking?)

Dynamic microphone, SM58 the industry standered most indestructable microphone ever built

Omnidirectional mic tests room sound, condenser mic

Audio tectica, microphone, low cut means that low frequency will no be picked up when button on on, pad button reduces decibels going into mic, condenser mic, mic clip for this gives less chance of getting every vibration in room

Phantom power box, gives mic power when plugged into mic and outlet

Condenser needs power to operate, dynamic doesn't (vibration between two metal plates)

Proixmity affect, closer you are to sound source, more bass....father away, less bass

Polar pattern is a pickup pattern

Cardioid is a pickup pattern in the shape of a heart

Omni directional means all hearing, pickup pattern or type of microphone, sounds same no mattter direction

Super cardioid, tend to get tail off back of mic, on bottom o mic there is a pickup pattern, make skinner heart

Shotgun, much narrower pattern than omni cardion or super cardiod, high frequency pickup directly behind microphone, best pickup pattern is directly in front of microphone

Condenser mic is almost all directional

AKG414 condenser mic, can adjust polar pattern, very sensitive, cleaner sound when recording

Electronic pickups on guitars and basses are used by PZM mic

Impedance is measured with "z"

Wavelab Software Mobile recording Devices

Any device that generates a voltage has an output impedance

Anything that is receiving a voltage has a degree of impedance

Amount of water pressure in a tube is measured in volts

As water:

The amount of flow of the water is the current and it is measured in amps

Current is based on impedance

Size of water pipe is impedance

Low impedance to high is better than high to low

Line level means high impedance, mic means low impedance

Pre amp amplifies current to high impedance

Distortion is created by pre amp

Impedance metaphor:



Low impedance High impedance

Impedance is a lot like your heart and veins. Your heart is pumping all this blood to your veins, so it is low impedance, but your veins are high impedance because they can only fit so much blood in them.

Logic Tricks:

Recorded something in mono? Need to split the track into left and right?



Remember to Disconnect the new split file!

Clarinet Recording Project:



**1. Microphone choice -** You can use many microphones on a clarinet, and there's no real standard. A high quality cardioid condenser microphone is recommended, although in a pinch a Shure SM57 or similar dynamic microphone will work fairly well. Since the clarinet has a fairly low tone, you'll want a microphone that can faithfully reproduce that, although it's not low enough to require a specialized microphone

Choice- Cardioid Condenser Mic (AKG)


 * 2. Microphone placement -** The sound of the clarinet can be reliably recorded by putting a microphone about a foot away from the bottom half of the instrument, angled towards the finger holes

The practical sonic spectrum of the clarinet sound is somewhere between 147 Hz and 12,000 Hz. distance of of 6 inches to 1 foot.

the most "true" sound comes from placing the microphone a few inches above the left hand fingers at about the second or third tone hole from the bottom.
