Room factors to be considered should include, but are not confined to:
•
Interference and noise sources
•
Line-of-sight obstructions between microphone and receiver
•
Reflective surfaces
•
Location of the VLR 102 receiver
•
Best location is 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; for example, too close to the
projector
•
Corners of the room
•
On walls, at less than 6 feet (1.8 m) or more than 12 feet (3.6 m) up from the
floor

Need for optional VLR 102SR Secondary Receiver
One or more secondary receivers (VLR 102SR) may be needed if:
•
The room is larger than 35 feet (10.6 m) by 35 feet (10.6 m).
•
Obstructions exist between the microphone and the receiver.
•
The room is odd-shaped; for example, 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 or covered. Dark surfaces reduce signal reflection.
