Your Job: As the Audio Engineer, it is your job to gather information needed to solve Problem #3 being faced by the cast and crew of Annie, Jr. and use this information to propose a plan of action to solve this problem.

Problem #3- The schools amplification system for the stage microphones suddenly stopped working.  A new amplification system would cost $5000 dollars.  Hiring a professional to come in and repair the system would cost $2000.  The budget cannot pay for either of these options.  Is there something you can do to design a "make-shift" amplification system so that the audience will be able to hear the actors' performing their lines on opening night?
