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

Need for optional VLR 102 SR secondary receiver
One or more secondary receivers (VLR 102 SR) may be needed if:
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
