I need help with this assignment on gain structure. I have attached it for better viewing. Thx

Assignment 6: Gain Structure

For your final assignment this week, you will work out the following gain structure. Please show all your work. Credit will not be given for incomplete answers.

For this assignment, you will calculate audio signal levels within the following gain structure.

Use the following specifications:

• Source is 103 dB SPL @ 4 feet

• Mic is 18 feet from source

• Mic sensitivity: 1 pascal yields -42 dBV

• Mic pad reduces audio level by 12 dB

• Mic preamp boosts audio level by 62 dB

• Fader reduces audio level by 6 dB

• A 1.75 volt input to the power amp yields 52 watts into 8 ohms

• Speaker is rated at 4 Ω

• Speaker sensitivity: 1 watt yields 85 dB SPL @ 4 feet

• Listener is 10 feet from speaker

Calculate the signal level at each of the eight locations indicated in the diagram, using the required units (dB SPL, dBV, watts, etc.). For each location, include a complete set of formulas and calculations.
