Reflection
Line of sight from the microphone to the receiver is ideal; however, reection of the IR
signal also plays a part in the coverage for most rooms. For example, if the speaker with
the microphone is facing a screen, the IR signal may reect off the screen surface to
the receiver in the middle of the room. Ideal conditions for reection are light colored,
smooth surfaces (for example, white drywall). Items to consider that may affect reection
include:
• Ceiling type (such as drop, spline, or hard lid)
• Wall type (such as drywall, cement, acoustical panel, or brick)
• Wall coverings (such as wall art, hangings, or dark colored paint)
• Curtains and blinds
• Furniture (such as bookcases or easels)
