How can we balance the differences in levels? e. Once the levels are balanced, how do the signals vary in sound quality or timbre? 2. Levels and EQ a. What is a gain stage? b. What is unity gain? c. What is Equalization (EQ)? d. What is the significance of EQ when the signal is a pure sine wave? e. What is the significance of EQ when this signal is a complex wave? f. How have we used EQ in previous demonstrations? If so, how? 3. Panning and Routing a. What are the applications where one would send different levels of the same signal to different speakers? b. What is panning? c. What is pre‐fader listen (PFL)? d. What is after‐fader listen (AFL)? e. What are some of the applications of PFL? f. What are some of the applications of AFL? 4.
