are set to Flat
To adjust the overall level of both the Sub and the satellite, use the SP® 118P 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 with the Sub gain knob..
If the SP® 2P is located in a different position than on top of the SP® 118P Sub pole, then the polarity of the SP®
2P may need to be changed for best results at the crossover region.
Setting the Levels Between the SP® 118P Sub and an SP® 4P Full-Range Speaker System
In order to set the levels of the subwoofer and the satellite full-range speaker to each other, you first set the SP®
118P Sub gain control (6) to the straight up detent position. Then the SP® 4P gain knob should be set to the
following position for the following gain relationship:
10:00 clock face position (second dot to the left): Sub is hot by approx. 8 dB, above the nominal level of the SP®
4P.
11 clock face position (first dot to the left): Sub is a little hot by approx. 4 dB, above the nominal level of the SP®
4P.
12:00 clock face position (straight up): Flat setting, SP® 118P Sub and SP® 4P equal output levels.
This setting will provide the most natural reproduction of vocals and acoustic instruments, when the EQ Presets
are set to Flat.
These settings are for the SP® 4P set right next to the SP® 118P Sub, in the same plane as the Sub.
Setting the SP® 118P Sub Controls for Use with Other Satellite Speakers
As per the above section, overall level is set by the SP® 118P 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 SP® 2P/4P 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 overall.
Cables from the High Pass Processed Outputs (11)
The preferred method of connecting a full-range satellite speaker system to the SP® 118P 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 SP® 118P 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 SP® 118P Sub,
as these usually have better shielding and materials and will provide greater long-term reliability. . It is usually
a good idea to leave some slack at the output of the SP® 118P Sub, and also to tape the cables down or run them
under a cable guard to avoid anyone tripping over them or pulling the SP® 118P Sub over when it is holding a
speaker on top of it's pole.
