Setting the Levels Between the RBN™118 Sub and an RBN™112 Full-Range Speaker System
The ideal location for placement of the RBN™112 full-range speakers is on top of the RBN™118 Sub pole. In that
close proximity, the following settings will provide the best results in the crossover region, and for tonal balance.
In order to set the levels of the subwoofer and the satellite full-range speaker to each other, you first set the
RBN™118 Sub gain control (6) to the straight up detent position. Then the RBN™112 gain knob should be set to
the following position for the following gain relationship:
12:30 clock face position (half-way between straight up and the first dot to the right): Sub set hot by approx. 6
dB, above the nominal level of the RBN™112.
1:30 clock face position (half-way between first dot to the right and the second dot): Sub set a little hot by ap-
prox. 3 dB, above the nominal level of the RBN™112.
2:30 clock face position (half-way between second dot to the right and the third dot): Flat setting, RBN™118 Sub
and RBN™112 equal output levels
This setting will provide the most natural reproduction of vocals and acoustic instruments, when the EQ Presets
are set to Flat
To adjust the overall level of both the Sub and the satellite, use the RBN™118 Sub gain knob (6) to adjust the
overall levels. Whatever relative levels exist between the Sub and the satellite speaker, will be maintained as the
overall levels go up or come down.
If the RBN™112 is located in a different position than on top of the RBN™118 Sub pole, then the polarity of the
RBN™112 may need to be changed for best results at the crossover region.
Setting the RBN™118 Sub Controls for Use with Other Satellite Speakers
As per the above section, overall level is set by the RBN™118 Sub gain knob (6), and relative gain is set by the
satellite speaker's gain or level knob.
For other speakers, several other adjustments may need to be made.
Speakers other than the RBN™112 may need a polarity reversal to be made, preferably at the satellite speaker,
rather than at the Sub.
The satellite speaker polarity should be tried both ways to assure the best performance in the crossover region.
The high pass crossover frequency can be adjusted between three choices:
100 Hz, 110 Hz, and 120 Hz.
Note that using the lowest frequency crossover point (100Hz) does not often make for the best results, in fact,
use of the 120 Hz setting is recommended in general over the other two choices, for best results in general.
Cables from the High Pass Processed Outputs (11)
The preferred method of connecting a full-range satellite speaker system to the RBN™118 Sub's High Pass Out-
puts (11), is to use a balanced XLR cable no longer than necessary to comfortably reach the satellite speaker
system.
If the satellite speaker is on top of a pole above the RBN™118 Sub, then a 6 foot cable will be plenty long. A 10, or
20 foot cable could also be used, but cables longer than that will only allow more interference pickup, and start to
loose high frequency information. Use of high quality, premium cables is recommended for the RBN™118 Sub,
as these usually have better shielding and materials and will provide greater long-term reliability. . It is usually
