Use of the speaker
Both the SUB 115A and the 118A subwoofers are perfect for producing low frequencies, also known
as bass. The SUB 115A produces a sound that accentuates kicks and gives a bass-punch, while the
SUB 118A has a larger woofer and is more capable of reproducing the lowest bass sounds, providing
a deep, warm bass.The SUB-series subwoofers are equipped with their own amplifier module, which
eliminates the need of an external amplifier. This amplifier module matches perfectly with the
characteristics of the other components.
The subwoofers are equipped with an internal crossover, which can enhance your sound performance
and audio quality, when using active speakers for your high and mid frequencies. The internal
crossover takes the incoming signal (coming from your PA- or DJ-mixer) and takes out the low
frequencies. These low frequencies will be reproduced by the subwoofer itself. The high and mid
frequencies will be sent to your connected active speakers.
This system provides optimal performance, because your normal speakers do not have to reproduce
low frequencies anymore, leaving more room for your high and mid performance. The subwoofer also
receives the right frequencies, as your subwoofer can not reproduce high and mid frequencies.
The internal crossover is variable, so you can adjust the crossover point as you wish. This way you
can use any active speaker above this subwoofer, while changing the crossover frequency for optimal
performance and sound.
Make sure to connect the right audio sources to the right inputs and connect other active speakers
using the correct outputs. The subwoofer is capable of handling stereo signals, with XLR or 6.35mm
jack inputs. This way you can use one subwoofer with 2 active speakers, or one subwoofer on each
side if you prefer. The XLR outputs can be connected to most active speakers with a standard XLR-
XLR cable.
The internal 35mm distance pole adapter makes it possible to increase the distance between your
subwoofer and speakers. The subwoofer stays on the ground due to its weight and acoustical
benefits, while your speakers can be placed on a sufficient height. This way the high and mid
frequencies can be spread more evenly over your audience and the soundwaves will project further.
The built-in phase switch is provided for certain acoustic problems.
When placing the speakers at a slightly deviating parallel line,
your frequencies will be extinguishing each other, thus causing
certain frequency to be absent. This is also possible when using
active speakers and subwoofers that have certain frequencies in
common (as the crossover point is not a straight wall, but a
slightly deviating X-point.) The phase switch will shift the
frequencies slightly, thus placing the soundwaves of your
frequencies in perfect parallel shape. In use however, use your
ears to determine which sounds better. Do not use the switch
when not needed (try to place the subwoofers on a parallel line
first), but when you hear that certain frequencies are missing,
you might want to experiment with the phase switch.
