Learn the best choices to make when building your sound system.
By Ken DeLoria

 

Questions to Ask Before Planning Your Configuration

  • Is the room deeper than it is wide, or vice versa?
  • Is Stereo really going to add an expanded dimension? Or is it going to cause coverage problems for many of the audience members? Have you checked carefully to be sure you know where all listeners will be seated, especially when the audience is extra-large for special events?
  •  
  • How reflective are the side walls?
  • If considering a L,C&R system, does the mixing console support the use of L,C,R (many do) or will it be problematic to route signals to three main loudspeaker clusters by using a matrix or Aux sends? Does the budget support the extra loudspeakers needed to provide three clusters for L,C&R? Or perhaps the best results on all fronts can be achieved with a single central cluster.
  • Is the desired end result intelligibility (i.e., speech clarity such as worship facilities, commencement ceremonies, political rallies, etc.)? Or a massive wall of sound (i.e., dance, rave, rock)? (Hint: massive walls of sound are not difficult to create; clear and distinct intelligibility requires very careful planning).
