Using the Subwoofer
The RX-10SA studio subwoofer is a great addition to a pair of RX studio monitors but also works well with
monitors from other manufacturers. By using this subwoofer it’s possible to get an honest and accurate
representation of the lower frequencies in your productions. The subwoofer is designed to produce subtly
present lows but can also be used to add more bass to casual listening sessions combined with a set of RX
monitors and connected to a computer or television or as a DJ console expansion.
The RX-10SA is designed to work alongside a pair of studio monitors and to take over the processing and
production of any low frequencies in the audio signal. Thanks to a variable crossover you can set the cut-off
limit anywhere between 50 Hz and120 Hz. Any frequencies above the set crossover point are then sent to
the speakers while the frequencies below the limit are handled by the subwoofer to give the speakers more
headroom improving their performance.
Subwoofers like these are ideally used in larger rooms and as an addition to a pair of regular monitors.
Warning Before Use
The Devine RX subwoofers are capable of producing volume levels that can cause temporary or permanent
hearing damage. Use these units with care and keep the volume at a reasonable level when possible. The
volume should ideally be set to a comfortable level when listening to music.
Devine cannot be held liable for any injuries or damage resulting from the use of this product.
Connecting the Subwoofer
The Devine RX-10SA is ideally placed somewhere on the floor but preferably not in a (far) corner to prevent
dense sound effects. A tight sound is what’s usually desired. Try out different positions in the room with a
basic set-up that can be easily moved around. The response of the room the acoustics can have a huge
effect on the sound and how much bass is ultimately shaped. Feel free to experiment with the settings to find
what best suits the situation.
If possible use balanced cables and connections. In general XLR cables and TRS jack cables (can be
recognised by the tip ring and sleeve) are what’s used in a professional set-up where the subwoofer is
combined with a DJ mixer/console or an audio interface.
It’s also possible to use unbalanced cables in this case RCA and TS jack cables. But bear in mind that
unbalanced signals require more amplification power and are more sensitive to external factors which
increases the risk of interference and noise.
Audio Technology and Set-Up
Sound Sources, Interface & DAC
Once your studio monitors are in the right position it's important to use a good-quality sound source for the
best possible results. This includes audio files that ideally should be the best-quality original material and
not converted files.
The hardware used to play audio should also be the best quality possible. When playing files via a computer
(PC or laptop) or a mobile device (smartphone recorder or tablet) it's a good idea to use an audio interface
or DAC (Digital to Analogue Converter) that will convert digital files into an analogue signal while retaining as
much of the original quality as possible. Built-in sound cards especially cheaper models and those found in
mobile devices tend to have a negative influence on the sound.
The audio interface or DAC you use should preferably have a relatively high output with plenty of headroom
to prevent problems with distortion and ensure the audio signal reaches your monitors at a sufficient volume
without the need for much extra amplification. Any extra amplification that's required can have a negative
influence on the audio signal.
Cables
The information in this user manual is subject to change at any time without notice.
Version 1.0 Date of creation and author's initials:21-07-2020 RV Revision date and author's initials: -

The type of cables used can also influence the quality of the sound. For best results use good-quality
balanced signal cables with TRS jack plugs or XLR connectors. Using unbalanced cables is also possible but
this can have a negative influence on the volume of the incoming signal and makes it more sensitive to
interference.
In general studio and recording equipment is always fitted with balanced outputs. Consumer products like
smartphones and laptops tend to have unbalanced outputs.
Making Volume Adjustments
These Devine studio monitors are equipped with a volume control that can regulate the incoming signal if
necessary. It is designed to be used to adjust the monitors not to correct issues with the incoming signal.
When using devices like a smartphone or laptop the incoming signal may be relatively weak. In this case a
DAC or a device that is capable of boosting the signal like an audio interface a mixer or a DI box should be
used.
Ideally you'll be able to control the volume of the signal your DAC or interface sends to your monitors. This
can also be software-controlled like the volume control on your computer laptop or mobile device for
instance. It could also be a separate passive or active volume controller that regulates the level of the
analogue signal. These often have simple 'dim' or 'mute' buttons that allow you to easily hal ve the sound or
mute it entirely. These features are handy when you need to discuss the sound with someone while listening
for example.
Crossover
The RX-10SA is equipped with a built-in low-pass crossover which filters the sound of the input signal and
takes out any lows up to a certain limit. This limit can be set between 50 Hz and 120 Hz using the crossover
control. Again feel free to experiment with the settings to find what best suits your set-up.
Thanks to the filtering and removing of the lows your regular speakers or monitors are able to focus on a
narrower frequency range. Since the reproduction of lows costs more energy than that of other frequencies
this not only boosts the performs of your complete set-up but the overall energy efficiency and the level of
definition in the audio.
Phase switch
The phase switch enables you to mirror the sound reproduction of the subwoofer by 180 degrees. This can
be useful when you’re dealing with a combination of factors including:
– Fading frequencies caused by the crossover not setting a hard dividing line but instead creates an X-
shaped gradient with a specific slope. This then causes certain frequencies to partly overlap.
– Acoustic interference that causes a ‘pounding’ sound effect.
Experiment with the settings to find what best suits the situation.
Status LED
The subwoofer is equipped with a status LED on the front (behind the Devine logo) that lights up when it is
powered on.
Overload and security
There is no overload indicator on this subwoofer because it is not designed to be used for listening at high
volume levels especially for longer periods of time. Pay careful attention when listening to the subwoofer to
determine whether it is set at a suitable volume level. If there is any distortion and/or crackling noises lower
the volume immediately to prevent damaging any components.
This subwoofer is not designed to perform continually at a high volume and should not be used for parties or
events. It should be used for its intended purpose only which is listening to audio at a comfortable volume.
This can include recreational activities like listening to background music or amplifying the sound from your
television.
Devine cannot be held responsible for any components damaged due to overload and as such any instance
of damage caused by overload is not covered under warranty.

Component and housing protection
This subwoofer is not designed for mobile use. If it needs to be transported it should be placed in the original
packaging or in a suitable flight case with a foam inlay of sufficient thickness to protect it against damage.
This subwoofer is not impact-resistant because it is designed to be placed in a permanent spot in your studio
and because any metal or plastic protective grilles can negatively influence the sound.
The bass port should be kept empty at all times and not used for storage.

Troubleshooting
If you have a problem with your subwoofer you can consult this troubleshooting section for possible
solutions. If after consulting this section the problem remains unresolved please contact your retailer for
more information and/or help.
This troubleshooting section contains information on how to solve the most common studio monitor
problems but it does not and cannot cover every eventuality. It is possible that you won't find your problem
cause and solution in this section due to differences between products.
Problem Possible cause Solution
The subwoofer won't turn on Cables are not (properly)
connected
Check the cable connection between the
subwoofer and the power socket
Inactive power socket Check that the socket is turned on and if
using an extension cable with a switch
check that this is also turned on.
Defective fuse Check the fuse next to the subwoofer’s
power connector. If the fuse is blown
replace it with the same type of fuse.
Volume is too low Output volume from the source
is too low
Check the volume on the source device and
turn it up if possible. It should not be
necessary to turn the volume level on the
subwoofer all the way up to bring the sound
up to an acceptable level. If changing the
volume on the source device is not possible
a good audio interface or preamplifier
should also be used.
Gain control is too low Turn up the gain control on the monitor
Certain frequencies are too
low or too high
The subwoofer has not been
placed in an optimal position
Experiment with the positioning of the
subwoofer. If not placed correctly this can
result in certain frequencies being amplified
or dampened.
EQ or sound transducers Some computers have built-in sound
controls with equalizers or sound presets.
These should not be used as they will
negatively influence the sound of the
subwoofer.
Audible interference Using unprotected cables Using unbalanced cables may cause
interference. Use balanced cables
whenever possible. If this is not possible
using a DI box directly after the output will
balance the signal.
High gain and weak signal It's possible that there may be interference
in the signal that is relatively loud compared
to the audio signal itself. This can happen
with a weak signal from the source which is
then amplified by the subwoofer
Ensure that the signal from the source is of
sufficient strength so that less amplification
is needed.
Interference in signal Unearthed power sockets Ensure that your subwoofer is always
connected using the included cable and that
an earthed power socket is used.
Equipment in the same power
group causing interference
Equipment including fridges freezers and
microwave ovens in the same power group
are capable of causing interference. Try to

connect all of your studio equipment to the
same power group with no other devices
attached. If this is not possible experiment
by connecting your devices to different
power groups to see if that solves the
interference problem.
Audible resonance or
vibrations
Speakers not isolated from
surfaces
When your speaker is placed on a surface
like a desk or a monitor stand it should be
isolated to prevent audible resonance or
vibrations. Monitor isolation pads are the
best solution for this.
Distorted clipping crackling
sound
Source device is transferring a
distorted signal
Check if any of the connected source
devices is transferring a distorted signal and
turn down the volume on the device if
necessary.
Volume control is too loud Turn the volume down
Woofer is defective If a subwoofer is exposed to a loud
distorted or clipped signal for a longer
period of time this can cause permanent
damage to its internal components. If you
suspect that the woofer is damaged contact
your local retailer for assistance.
