Stefan Grove - Lesson 4Posted by Stefan Grove on 2013-11-07

Here are my notes for Lesson 4: Chapter 4 Section 1: - Path of guitar soundwaves:     - Vibrations from guitar goto the pickups or "The guitars microphones"     - Pickups convert vibrations to low level electric voltage     - Goes to amp, amp boosts the current     - Goes to microphone placed in front of amp, coverts back to low level electric voltage     - Goes through a microphone preamplifier, increases voltage from mic level to line level     - Goes to analog to digital converter     - Goes to protools     - Goes to digital to analog converter     - Then you can listen to it again - Signal flow = The path a signal takes, from beginning to end - Standard audio connectors:     - Two conductor connectors:         - NL2 (Speakon)         - Double Banana         - Unbalanced 1/4" TS (Tip-Sleeve)         - RCA         - BNC     - Three conductor connectors:         - XLR         - Balanced 1/4" TRS (Tip-ring-sleeve)         - TRS MIL         - TT/Bantam         - 1/8" Mini     - Multi-pin connectors:         - ELCO         - DL         - D-SUB/DB25         - CAT 5 Review Questions: XLR: 3 "pins" Blue end and black "Hollow" end RCA: Normal connection for cable tv TRS: Silver with black end, has 2 rings on front - Analog Cables:     - Speaker wire     - Coaxial     - Singles conductor wire with conductive shield     - 2 conductor wire with conductive shield     - Multi-Conductor - Analog = "Low voltage electricity - Common voltage levels:     - Microphone level = -60 db     - Instrument level = -30 db     - "Consumer" line level = -10 db     - "Pro" line level = +4 db - Balanced connections allow signals to travel a longer distance without degrading, as well as offering a higher degree of noise isolation - (A+noise)-(-A+noise) = A+noise +A-noise = 2A - Balanced connections are 6 db louder than unbalanced connections Review Questions: - Microphone level is "-60 dbu - Pro audio level is "+4 dbu - A unbalanced connection has three conductors and transmits a signal out of phase which eliminates unwanted noise that could be picked up on a cable run: False Unbalaced cables:     - RCA cables: mostly used for consumer grade audio components, unbalanced line level signals (-10 db or lower) Pin in center is hot, outer prongs connect  to ground     - Instrument cables: used for electric guitars, and keyboards, (-30 db to -10 db)...

Stefan Grove - Lesson 2Posted by Stefan Grove on 2013-11-07

Here are my notes for Lesson 2: Chapter 2 Section 1: - All matter is composed of atoms - An atom is made up of neutrons, protons, and electrons - Nucleus (Center of an atom) is made up of protons and neutrons - Electrons = Negative charge - Protons = Positive charge - Neutrons = No charge - If the atom has same number of protons and electrons, it is said to be "stable" - resistance is the measure of resistance to the flow of electricity measured in ohms - Current = Measure of the amount of electric charge passing a point in an electric circuit per unit of time - 3 basic measurements of electricity =      - Voltage (V)     - Current (I)     - Resistance (R) - Ohm's law     - V=IR (Voltage = Current times resistance     - Variations of above: current = Voltage divided by resistance     - Variations of above: Resistance = Voltage divided by current Chapter 2 Section 2: - Analog circuit = Circuit that carries a voltage that is either continuous or changing     - Analog in 2 categories:         - Series         - Parallel - Digital Circuit = transmits information, can transmit binary values in the form of an on or an off signal - Power Plant, Step-up Tansformer, Tower, Transmission Substation, Distribution Substation, Transformers, Home Review: - Voltage is the measure of electromotive force in the electronic circuit - Resistance is the measure of the opposition to the flow of electricity - Electricity is the flow of free electrons from atom to atom - Current is the measure of the amount of electric charge passing a point in an electric circuit per unit of time - If an atom has more protons than electrons it is said to be positively charged - Analog circuits transmit voltage to components - Alternating current is current that flows in both directions - Electricity loses energy over long distance so low voltage transmissions help to extend voltage over a long distance, false - Electronic circuits can be broken down into to types: Analog and Digital - A digital circuit transmitts information in two values on (1) or off (0), True Read More >>
