Requirements and installation
We recommended that the SB115 be positioned far enough away from the audience, so
that the sound coverage is uniform over the entire audience. The distance separating the
SB115 from the closest listeners must be greater than the reverberation distance. Thus,
practically speaking, the SB115 must be placed at least 3 meters from the closest
audience members.
In terms of maximum sound level, the SB115 is designed to be aligned Step-Array column
loudspeakers. To maximize the power of the column loudspeakers, we recommend:
-
As many SB115 as there are SA180, SA250, R210
-
1 SB115 for 2 SA100 or 2 R110
When several SB115 are used to deliver the same signal, theoretically 3dB efficiency and
SPL may be gained by positioning them together (e.g. side by side or one on top of the
other). The maximum sound level obtained with two adjacent SB115s will then be 6dB
greater than that obtained with a single SB115. On the other hand, the sound coverage
may be more uniform if they are distributed around the room.
The SB115 can be placed horizontally on the floor, or vertically against a wall.
