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.
Warranty is void when damage to this speaker is caused by improper use. When any damage to this
speaker occurs, please contact your local dealer for help.

Practical information and tips for optimal use of your speaker system
For optimal performance and a long lifespan of your speaker, please pay attention to the following
when using your Devine subwoofer:
- This speaker is equipped with a CLIP limiter, which prevents damage to the speaker. This CLIP
limiter will activate at excessive volume levels and a red LED shows when the CLIP limiter is active.
Prevent the activation of the CLIP limiter system and the indicating LED. The CLIP limiter protects the
system from permanent damage, but is only effective at peak signals. Long term exposure causes
distortion and power overload, with possible permanent damage to your speaker system.
- When using an external mixer (such as a PA-mixer or DJ-mixer, make sure your master channel
sends out signals at 0dB maximum. This will provide optimal signal quality and with the volume control
on the speaker you are able to turn up the volume, just before the CLIP limiter LED will slightly flash.
This way you are using the speaker to its full potential with optimal sound quality.
- When using the crossover system and adjusting the volume and/or frequency balance between your
speakers and subwoofer(s), keep the master volume on a medium, neutral level which is comfortable
to your ears.
- Do not remove the protective cover in front of the voltage-switch. The correct voltage is pre-defined
at 230V AC. When selecting the wrong voltage you may cause permanent damage to the speaker and
its internal components. Only select the 115V AC option when your local power source is capable of
delivering this voltage.
- Do not switch the power on and off frequently as this reduces the lifespan of the speaker and its
internal components. The speaker can be used for a whole day without any cooling-down time, if
sufficient cooling is provided.
- The speaker is equipped with an internal fuse, located directly above the IEC power input section. If
this fuse blows for any reason, only replace it with a fuse that has the same values as the original fuse.
Do not bridge the gap with any electrical wiring or whatsoever as this voids your warranty.
- Severe shocks and impact must be prevented as much as possible. Secure this speaker properly in
place during transport to prevent damage to the housing and the internal components of the speaker.
