Audio Design Calculations in CTS-D Exam Guide
Looking for (more) clarification on pages 154-158 of the CTS-D Exam Guide Second Edition - Specifically on EPR calculation headroom and 70V Distributed Amplifier wattage Calculation
EPR Calc in CTS-D book incorrect?
Is the calculation shown on page 154 of the CTS-D exam guide incorrect?
70W Attenuator Wattage - Headroom Required?
Is a 100W 70V attenuator actually designed to pass 100W of 70V amplified signal to 100W*1.5 of networked 70V speakers?
Institutional Hallways - Standards
What do other people do when designing distributed speaker systems in institutional hallways? What I've seen in the real world meets none of the best practices.
Speaker and Amplifier HEADROOM Calculations
In calculating required amplifier channel wattage, there are two places where 'headroom' is involved. What is each headroom value intended for?
Speaker Coverage Patterns - From what is the % derived?
Common speaker coverage patterns include 50% (or edge-to-center) and 20% (Diagonal edge-to-edge), but what is it "20%" or "50%" of?
Question on EPR Calculation - Distance
Looking for insight on proper calculation of electrical power required - specifically which distance to use
