Extron electronic VLM 2000, VLM 1000 Room considerations, Room configuration, Receiver location

Room considerations

Room factors to be considered should include, but are not confined to:

•Room configuration

Room size, orientation, and layout

Location of windows, doors, skylights, etc., for potential light interference

Alcoves, bays, or sheltered areas

Location of any dark or covered walls (Dark surfaces reduce reflection of the IR signal.)

–Wall art

–Curtains/blinds

–Acoustical panels

–Wall material/texture

•Line-of-sight obstructions between microphone and receiver

Existing movable furniture (desks, tables, podiums)

Existing installed furniture (bookcases, racks, cabinets, workbenches, sinks, etc.)

Support pillars

Projector

•Ceiling and wall type (important in assessing the installation hardware needed)

Ceiling type (drop, spline, hard lid, etc.); structural type (wood, concrete, trusses)

Wall type (drywall, cement, brick, etc.)

•Receiver location

Best location: on the ceiling, at the middle of the classroom

If ceiling mounting is not possible, place high and centered on the longest wall.

Locations to avoid:

–Places where line of sight could be obstructed; e.g., too close to the projector

–Corners of the room

–On walls, at less than 6' or more than 12' up from the base

–Areas that receive direct sunlight
