Using the Studio Monitor
The Devine RX Series studio monitors include three models available in black and white. These are the ideal
monitors for producers looking for a balanced and neutral sound so they can properly assess their mixes.
The RX Series includes 5”, 6” and 8” models, referring to the size of the built-in woofer. The differences in
size and matching power capacities make sure the perfect monitor can be selected for any preferred style of
music. The 5” RX-5A monitors are ideal as compact reference speakers for smaller studios, while the 8” RX8As are designed for larger rooms and offer enhanced bass reproduction thanks to the bigger woofer.
The soft-dome tweeter and woofer ensure a balanced reference sound intended to simulate smaller 2.0
speaker systems, much like the ones your listeners have, either next to their computer or built into their
television.
Each model can be expanded with a separately-available subwoofer to simulate 2.1 set-ups with a bigger
subwoofer, much like sound-bars, Hi-Fi systems and computer-related audio gear.
Warning Before Use
The Devine RX studio monitors 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 that may result from the use of this product.
Connecting A Set of Monitors
The Devine RX studio monitors can be set up on any flat and stable surface, usually next to your computer
or laptop with one speaker placed on the left side and the other on the right.
After the speakers have been positioned as preferred, plug the power cable into your monitors, then connect
up any correct signal cable, depending on the audio source. If you don’t have the right cables, you can
contact your retailer for advise.
Connecting an audio source is done using ONE of the possible connections. In this case, that includes
balanced 3-pin XLR, which is the recommended option because the plug is unable to rotate inside the socket
and doesn’t short-circuit when inserted. Naturally, the other inputs can be used as an alternative. It is
nonetheless advisable to work with balanced signals as much as possible. These are less sensitive to signal
interference caused by external factors.
Important: Always make sure to use only ONE connection at a time, so either XLR, the TRS jacks OR the
RCA inputs.
General Use
Placement and Positioning
Studio monitors are highly directionally sensitive speakers that come with a so-called ‘sweet-spot’ in terms of
sound dispersion, especially when it comes to the high frequencies. This is the position where the monitor
sounds best relative to where you sit and will give you the most accurate sound reproduction.
The ideal set-up can be achieved by creating an equilateral triangle where you are the third point. If y our setup allows for it, make sure each corner covers a 60° angle. The distance between each speaker and the
listener should be approximately 1 metre for near-field studio monitors like the Devine RX Series models.

Be aware that if your monitors are placed on a desk, they may not be positioned at the right height (ear
height).
Isolating and the Right Height Placement
Once your monitors are in the right place, it's important to ensure that they are also positioned at the right
height. Monitors placed on a desk are rarely positioned at the right height for you to be able to experience
the 'sweet spot', as they are usually not directed towards your ears.
In the most ideal scenario, you'll use studio monitor stands to ensure your monitors are at the perfect height.
When you're sitting at your desk, the woofer and tweeter should be at the same height as your ears. If this
setup simply isn't possible, you should consider investing in special isolation pads which can be placed
under your monitors and adjusted to the perfect angle. In this case, your monitors can be angled towards
your ears. Ideally, you'll be able to look directly at the status LED or speaker components.
In addition, using isolation pads gives you the added advantage of preventing vibrations from the woofer
being transferred to the surface they're standing on, resulting in a better, more neutral sound overall without
any interference.
Positioning in Relation to Walls
These studio monitors have a bass port on the front, which means that the low frequencies reproduced by
the woofer are delivered with more expression and presence in the overall sound. For an optimal sound, it’s
important that the studio monitors are placed close to a wall for improved bass spread via reflections. This
will give you noticeably better results and a fuller sound compared to a set-up in an open space.
It’s recommended to place the speakers roughly 30 to 100 cm away from the wall. Experiment with the
positioning to get optimal results.

Version 1.0 Date of creation and author's initials:21-07-2020 RV Revision date and author's initials: -
It’s not recommended to place one of the speakers in the corner of the room as this might create an
unbalanced overall sound. If corner placement is the only possibility, try to use the corner to create a
symmetrical configuration with a corner desk and have the bass ports directed at one of the walls.
The Long or Short Wall in a Room
In a rectangular room, it’s recommended to place the monitors next to one of the two shorter walls. This way,
the sound is better spread throughout the space and any reflections are broken up and diminished as much
as possible. This ensures that the sound that’s directly aimed at your ears is dominant and that the rest is
only barely (or subconsciously) heard.
If the room happens to be so small that the opposite wall is between 1 to 2 metres away from your listening
position, any problems with the acoustics might be solved by using acoustic absorbers that reduce any
sound reflections behind you. Since the placement of acoustic treatment requires a certain level of
knowledge and expertise, it’s recommended to contact a specialist for optimal results. The type of acoustic
treatment differs depending on the problem or purpose.
Other Tips for Monitor Placement
Take the time to find the optimal position for the monitors. A couple of centimetres can mean a world of
difference in terms of sound quality, considering reflections can easily reinforce or dampen certain
frequencies.
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 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 halve the sound or
mute it entirely. These features are handy when you need to discuss the sound with someone while listening,
for example. As such, no volume control has been fitted to the front of the RX monitors.
HF Trim
To match the performance of the speakers, the Devine RX Series monitors feature an HF trim control for
incremental adjustments of the tweeter level. If your monitors are close to a wall and produce unwanted and
annoying low frequencies, this can compensated for with the HF trim.
Status LED
The monitors are equipped with a status LED on the front (behind the Devine logo) that lights up when they
are powered on.
Overload and security
There is no overload indicator on this monitor 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 monitors to
determine whether they are set at a suitable volume level. If there is any distortion and/or crackling noises,
lower the volume immediately to prevent damaging any components.
These monitors are not designed to perform continually at a high volume and should not be used for parties
or events. They should be used for their 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 of
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
These monitors are not designed for mobile use. If they need to be transported, they should be placed in the
original packaging or in a suitable flight case with a foam inlay of sufficient thickness to protect them against
damage.
The monitors are not impact-resistant because they are designed to be placed in a permanent spot in your
studio and because any metal or plastic protective grilles can negatively influence the sound. Ensure that the
woofer and tweeter of both monitors remain untouched to prevent any damage.
The bass port should be kept empty at all times and not used for storage.
Devine cannot be held responsible for any dented woofers or tweeters and as such, any instance of dented
woofers or tweeters is not covered under warranty.

Studio Monitor Troubleshooting
If you have a problem with your studio monitors, please consult the 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
Monitors won't turn on Cables are not (properly)
connected
Check the cable connections between both
monitors 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 monitor'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
monitors 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 monitor has not been
placed in an optimal position
Experiment with the positioning of the
monitor. 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 your studio monitor's
neutral sound.
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 monitor.
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 monitors are 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

Version 1.0 Date of creation and author's initials:21-07-2020 RV Revision date and author's initials: -
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 or tweeter is defective If a studio monitor 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 or tweeter is
damaged, contact your local retailer for
assistance.
