2. Requirements and installation
We recommended that the SB110 be positioned far enough away from the audience, so
that the sound coverage is uniform over the entire audience. The distance separating the
SB110 from the closest listeners must be greater than the reverberation distance. Thus,
practically speaking, the SB110 must be placed at least 3 meters from the closest
audience members. The SB110 can be placed to the ceiling to if necessary.
In terms of maximum sound level, the SB110 is designed to be aligned Ray-On column
loudspeakers. To maximize the power of the column loudspeakers, we recommend:
-As many SB110 as there are R210
-1 SB110 for 2 R110
When several SB110 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 SB110s will then be 6dB
greater than that obtained with a single SB110. On the other hand, the sound coverage
may be more uniform if they are distributed around the room.
The SB110T is equipped with a 100V line transformer with a power of 100W. Its maximum
sound level is therefore lower than that of the SB110 (about 8dB less). The low cut-off of
the transformer is 35Hz.
The SB110 can be placed horizontally on the floor, or vertically against a wall using the
accessory SB110_KMV (figure 1).
