1. Introduction
The SB110 subwoofer is designed to extend the bass response of column louds-
peakers such as StepArray or Ray-On. It is passive, has no lter, and therefore
requires ltering upstream of the amplier.
SB110 is very compact, and can be positioned both horizontally and vertically
for optimal visual integration.
The high-end 10-inch loudspeaker is loaded with an enclosure operating in
interactive dual volume mode. It achieves a remarkably low cutoff in a small
volume, while yielding sharp and dynamic sound.
The NUT processor comprises modules for managing subwoofers, with presets
corresponding to the SB110.
The SB110 also exist in 70/100V version under the reference SB110T.
Applications
Background and foreground music, audio-visual programs, small live, in :
• Meeting and conference rooms
• Amphitheaters
• Places of worship
• …

2. Requirements and installation
We recommend that the SB110 be positioned far enough away from the au-
dience, so that the sound coverage is uniform over the entire audience. The dis-
tance 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 with Ste-
pArray and Ray-On column loudspeakers. To maximize the power of the column
loudspeakers, we recommend:
• as many SB110 as there are SA180, SA250, R200
• 1 SB110 for 2 SA100 or 2 Ray-On R100
When several SB110 are used to deliver the same signal, theoretically 3dB ef-
ciency 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 cutoff of the transformer is 35Hz.
The SB110 can be placed horizontally on the oor, or vertically against a wall
using the accessory SB110_KMV (Figure 1).

3. Wiring
For SB110, use 2 x 1.5 mm² cable when the distance between the amplier and
the SB110 is less than 50 m; 2 x 2.5 mm² for greater distances.
For SB110T, use a 2 x 0.75 mm² cable (minimum).
The SB110 / SB110T connector can be used to connect several subwoofers in
daisy chain conguration as shown in Figure 2. This naturally presupposes that
a suitable amplier is used. Thus, for N subs connected to the amplierin a
daisy chain conguration:
• In 100V mode: Amplier power ≥ N x 100W,
• In low impedance mode: The amplier must withstand a load impedance
of 8/N Ohms, and must deliver sufcient maximum power.

4. Filtering and settings in NUT
4.1. Recommended equalization
Table 1 gives the recommended equalization and crossover settings for the
SB110 used with StepArray and Ray-On column loudspeakers. The correspon-
ding response curves are given in Figure 3.
Cell # Type Frequency (Hz) Gain (dB) Width (oct)
1 Low-pass - 2nd order 160 Hz -8 dB
2 Low-pass - 2nd order 180 Hz -1 dB
3 Low-pass - 2nd order 180 Hz -2 dB
4 High-pass - 2nd order 40 Hz -1 dB
5 High-pass - 2nd order 40 Hz -2 dB
6 Parametric 40 Hz +6 dB 0,3 oct

4.2. Excursion limitation
High-amplitude signals with very low frequencies
cause large membrane excursion. Excessive excur-
sion causes harmonic distortion, which degrades the
sound quality and causes a risk of damage to the
loudspeaker.
It is desirable to limit the amplitude of the deections either by reducing the
amplitude of the applied signal or by placing a high-pass lter upstream of the
amplier, for example, a second order Butterworth lter at 80Hz.

4.3. NUT Processor settings
The following paragraphs describe the steps involved in setting up an installa-
tion using an SB110 and a NUT processor. It is of course possible to use other
processors. Under these circumstances, the settings below must be transposed
for the processor used.
Step 1 : Group the SUB channel with the main channel: To do this, assign
these two channels to a single group (Figure 4). The levels of the SB110 and the
high channel (here SA250P) are thus controlled by the group gain.
Figure 3 :
The SA250P and SB110 outputs are assigned to group B in the Vo-
lume settings block. The grouping of the outputs is also displayed on the right
of the main screen (right)

Step 2 : In the equalizer of the SB110 channel, select the desired setting. For
example, «SB110 subwoofer» (Figure 5). The lter thus selected includes the
equalization recommended previously.

ting with StepArray or Ray-On
Step 3 : In the equalizer of the main channel, select the desired setting. For
example, «StepArray with SB110 subwoofer», or «Ray-On with SB110 subwoo-
fer» (Figure 6).

Step 4 : In the «Volume Settings» window, set the relative levels of both
channels. For example -7dB for the main channel and 0dB for the SB110 chan-
nel (Figure 7). The gain difference (in dB) of the two channels depends of
course on the gain difference of the amps used for the main channel and the
SB110 channel. The easiest way to adjust these gains is to use a sound level
meter.
