Course Description
Work through the calculations AV projects actually depend on, from screen sizing and throw distance to loudspeaker impedance and decibel change, with enough practice to do them under exam conditions.
Who it’s for. Technicians, installers, and designers preparing for CTS, CTS-D, or CTS-I who want more practice with the math their prep classes assume they already have.
Learning outcomes.
Size displays and screens by working aspect ratios, diagonals, and the Pythagorean theorem into proportions
Convert scaled drawing measurements to real-world dimensions in both metric and U.S. customary systems
Calculate projector throw distance from a manufacturer's throw ratio and screen width
Apply Ohm's Law and power formulas to solve for voltage, current, resistance, or power in a circuit
Calculate total impedance for series, parallel, series/parallel, and distributed loudspeaker circuits
Determine decibel change using 10Log for power and 20Log for distance, voltage, and sound pressure
Calculate rack heat load in BTU and farthest-viewer distance for ADM and BDM viewing categories
