•  Optional VLR 102SR Secondary receiver. One or more secondary receivers (VLR 102 SR) may be needed if any 
of the following conditions exist:
  The room is larger than 40' by 40'.
  Obstructions exist between the microphone and the receiver.
  The room is odd-shaped, e.g., L-shaped or long.
  The room has recessed or sheltered areas, such as alcoves or bays.
  The room has large windows or windows on multiple walls.
  Portions of the walls are dark and/or covered. Dark surfaces reduce signal reflection. Take the following into 
consideration:
  –  Wall art 
–  Curtains/blinds 
–  Acoustical panels 
–  Wall material/texture
