Regarding microphones, what is meant by Frequency Response? What is happening when a sound is diffracted? Definition of Sound Reflections: Flat Smooth Convex Concave Corner Definition of Acoustics: Acoustic Isolation Frequency Balance Acoustic Separation Reverberation Cost Factors What are the two main factors when considering Transmission Loss in a room. The terms Live Room and Dead Room mean: What is the function of an ISO room/booth? How many untreated parallel walls should a good recording studio have? Parallel Walls are (good / not good) to have because they help produce: The best way to deal with Parallel Walls is to: In a control room which wall pair should be Reflective/Diffused and Absorptive – in that order? Without reconstructing the room, what is a cost effective way to limit Flutter Echos or Slap Echos? What is a Bass Trap’s function? Quarter-wavelength, Pressure-zone and Function traps are all types of: Define: Direct sound Early reflection Reverb What kind of materials absorb high frequencies? What kind of materials absorb low frequencies? What is required by a condenser mic that is not required for a dynamic mic? Microphones – Define the characteristics of the following: Dynamic Mic Ribbon Mic

Condenser Mic What percentage of your room should be Diffusion and Absorptive surfaces. Feedback – what is going on that makes audio feedback? What is the thing called in dynamic and condenser mic that moves, converting SPL into electricity. What Microphone pattern picks up mostly in Front of where the microphone is pointed? What Microphone pattern picks up everywhere no matter where the microphone is pointed? What switch would you turn on when someone is overdriving the pre-amp regularly? Which kind of microphone is less susceptible to being overdriven or takes a whole lot of energy to overdrive this kind of microphone? Why is a balanced (XLR) better than an unbalanced cable (1/4” & RCA)? What is meant by a “Flat Response”? Microphone Pick-up Patterns (p122) – Match them up

What is meant by “The Proximity Effect”? What meant by the “Transient Response”? What does a Pop Filter do? What is the 3:1 rule? What are the three main stereo recording techniques? What is the minimum number of microphones are required for a Mid/Side stereo recording? What is the function of a DI box? Four Questions regarding Microphone Techniques: What are the characteristics of: Distant Micing Close Micing Accent Micing Ambient Micing What are the fixes for microphone bleed through or leakage? (p133) What is the name of the kind of graphic shown here? What is this chart showing us about the microphone?

What is meant by Unity Gain? Be able to identify an XLR Jack and Connector Be able to identify a ¼” Jack and Connectror When to turn on Phantom Power? What is the angle tolerance of XY stereo mic technique. Where does one place a DI box in the audio chain?

Pro Tools Section: What is meant by “Region” or “Clip” in Pro Tools 10? Shuffle Mode means Slip Mode means Spot Mode means Grid Mode means New Session keyboard Shortcut: New Track keyboard Shortcut: In the new track window – how does one change the kind of track, e.g. Audio, Aux, Instrument… How do you close a Pro Tools session, but leave Pro Tools running? How many wires are required for a balanced connection.
