Introduction
Thank you for purchasing a Devine D-series power amplifier. These versatile, compact, reliable power
amplifiers feature modern technologies, which makes them small in size but powerful in output.
The Devine D-series feature special electronic circuitry which ensures that incoming signals are amplified
perfectly with optimal efficiency. The class D design and power supply require less power to ensure the same
power output level as compared to normal class A B power amplifiers.
Devine's D-series amplifiers feature a metal housing and a clean front panel combined with ventilation slots
to ensure proper cooling. Fan-cooling ensures that the components do not overheat when they are working
at full capacity.
The D-series amplifiers are equipped with various protective circuits like clip LED indicators and protection
against short circuits and overheating.
The D-series power amplifiers are small in size and depth so they can be installed in a 19-inch effects rack or
flight case instead of bulky, deeper racks. Thanks to the class D circuitry, the D-series amplifiers are very
lightweight, making a complete rack of D-series easy to carry and transport.
The D-series works perfectly with most passive loudspeakers. Please keep in mind that a power amplifier
should be capable of delivering almost 2x the required maximum load of your speakers. This ensures proper
headroom, making it impossible for the amplifier to work at full capacity should your speakers reach their limit
first. Comply with this guideline to avoid causing permanent damage by overpowering your speakers.
A power amplifier which cannot deliver the maximum power capacity of your speakers is more likely to clip or
distort. Clipping takes place when the input of the power amplifier and the gain settings are turned up to the
maximum level, which causes the internal electronics to exceed their limit. As a result, they will distort when
driven with a volume increase. This may cause permanent damage to your power amplifier as well as your
speakers.
Devine strongly recommends adhering to the advice in this manual to ensure that your complete speaker
system (power amplifier and speakers) is capable of delivering optimal sound quality and sound pressure
level, thus preventing permanent damage. Clipping and distortion prevention will be explained in more detail
later on in the Using the amplifier section of this user manual.

Using the amplifier
The Devine D-series amplifiers are built to last. To get the most out of your speaker system, it is
recommended you read this manual thoroughly to familiarise yourself with all the options and features of this
amplifier. Correct use of the amplifier will ensure that the expected lifespan of this device remains
unchanged, as overload of this power amplifier may result in damage to your power amplifier and or speaker
system.
Power ratings
The Devine D-series are a complete range of digital class D power amplifiers, each with their own individual
power ratings. This way, you are able to select the right amplifier for the job! The D-series consist of the D-
200, D-400 and D-600. The D-200 is the most affordable version, with a relatively low power rating. This is
the ideal power amplifier for speakers that do not need a large amount of power. The most powerful version
is the D-600, which can be used to drive a large subwoofer in Bridge mode, or a couple of PA-speakers.
To be sure that this power amplifier is used safely to power the speakers you wish to connect, pay attention
to the power ratings of your speakers.
If the RMS power rating of the power amplifier is identical to or max. 2x as powerful as needed to drive your
speakers, then the amplifier is suitable to use. For optimal performance, it is recommended to use a power
amplifier which is capable of delivering full power to your speakers.
It is not recommended to drive a speaker with a 300W RMS power rating, using a power amplifier with a
maximum power rating of 200W RMS. An amplifier with a rating between 300W RMS and 600w RMS would
be ideal because:
- a more powerful amplifier does not need to perform at 100% capacity when the speaker is already driven
with a signal at maximum performance.
- a more powerful amplifier has more headroom when driving a speaker at its maximum power level. This
means peaks in the music will not cause clipping (or signal distortion and possible damage as a result of
exposure to long-term clipping).
- a more powerful amplifier can often be used if you choose to purchase new speakers with a higher
maximum power rating.
- the cause of defective 'blown up' speakers is usually when power amplifiers create too much signal
distortion due to frequent and long-term clipping.
- most speaker power ratings are based on measured or calculated sine waves. The audio signal consists of
peaks and dips in the music. Most speakers are capable of handling certain (short-term) peaks as well as
unexpected signal peaks. It is therefore safe to use a more powerful amplifier to drive your speakers.
- Clipping can cause permanent damage to both your speakers and power amplifier. A powerful amplifier is
more likely to provide sufficient headroom, while long-term exposure to excessive amplifier power can have
a negative effect on your speaker system.
How far can I turn up the volume on the amplifier?
Keep in mind that the power rating of your speaker system and power amplifiers is usually measured or
calculated with sine waves. As music is commonly played through your speaker system (which has a
dynamic character), you should always monitor your speaker performance. Audio distortion could cause a
loss of signal quality, and excessive amounts of power could cause other signal quality issues and possibly
permanent damage to your speakers.
To maintain optimal signal quality, use the following checklist. This is a handy way to adjust your speaker
system so it performs optimally, but without losing audio quality:
1. Make sure your signal source is not overdriving. When using a DJ or PA mixer, or a DJ controller with
audio interface, make sure it does not send a signal that exceeds 0dB. Any value higher than 0dB will cause
signal distortion.
2. After you have checked step 1, carefully turn the amplifier volume level up as far as possible.
WARNING: When increasing the volume controls of your amplifier, always listen carefully to the connected
speakers and keep an eye on the clip indicators on your amplifier. Decrease the volume level of the amplifier

channels when any of the following situations are noticed:
- The amplifier channel clip LED lights up frequently.
- The speaker produces a slight distorted sound there is a noticeable loss of audio quality and
clarity.
To be sure that slight peaks in music do not affect your signal quality or performance, set your signal source
to +3 dB. Then, set the optimal volume level of your amplifier and pay close attention to your speakers and
amplifiers (as described above in step 2 of the checklist). When your speaker system performs at full output
capacity without audio quality issues, decrease the audio signal source back to the 0dB position. Now, when
a slight audio peak is sent out through your signal source, it will not affect your speaker system.
Signal source is often the source of the problem!
In most cases, the signal source of your system (usually a DJ or PA mixer, or a DJ controller) is the source of
audio quality problems. This is commonly caused by improper gain structure or excessive input signals to
your channels. Make sure to monitor every processed audio signal in your system for an optimal audio
performance. Please note that every fault in your signal source will be processed and amplified by your
speaker system.
Always make sure that the master output of your signal source does not exceed 0dB. If it does, however, this
could result in noticeable audio quality loss and possible distortion. Even when your master volume setting
does not exceed 0dB, an overloaded signal could be present on your channel inputs when the gain is set too
high. Pay close attention to the gain settings on your channel inputs and do not allow the input signal to
exceed 0dB.
Front panel
The front panels of all D-amplifiers are equipped with just a few
buttons and LED indicators. This makes it possible for professionals
and amateurs alike to work with any of the D-series amplifiers.
The front panel has the following controls and indicators:
Controls:
- Volume control for each channel, 0-10 (used to set the desired
volume for each channel)
- Power ON OFF switch (to switch the device on and off)
Indicators:
- Green signal LED (lights up when an incoming audio signal is detected by the amplifier circuitry)
- Red Limiter LED (lights up when the limiter is active and overloading of the amplifier components is
detected)
- Blue Power LED (power 'On' status indicator)
Input section
The Devine D-series amplifiers are equipped with a clearly marked
signal input section on the rear of the amplifier. This input section is
suitable for one stereo input signal while the input of your choice is
in use. Proper inputs can be found on PA-mixers, DJ mixers, DJ
controllers, audio interfaces and many other devices which provide
high-quality stereo line output signals. The D-series amplifiers are
equipped with balanced XLR inputs, as well as balanced 6.35 mm
TRS jack inputs. This ensures optimal quality and will help prevent
hum and buzz noise issues.
Devine does not recommend connecting a signal source without a clear volume setting display (like on an
MP3-player or smartphone), as it is not possible to see if the signal is below or above 0dB. However, it is
possible to connect such a device to an audio mixer to see how high the outgoing volume level of your
device is.
Any information and illustrations shown in this user manual are subject to change without further notice.
User manual version: 4.0 Creation date + author initials: 11-12-2015 RV Revision date + author initials: 10-12-2015 RV

The inputs of this power amplifier may be used as signal pass connections to daisy-chain multiple amplifiers.
Devine does not recommend linking more than three D-series power amplifiers in a daisy-chain setup so as
to prevent any loss of signal level and quality.
WARNING! Do not send two signal inputs to the amplifier at the same time! The combination of two signal
inputs will exceed the signal of the preamp section of the amplifier. Improper use of the inputs may cause
loss of quality or even permanent damage to the amplifier.
Ground lift option
The ground lift option is used to remove the ground connection of any incoming balanced input signal. This
may help to remove noise caused by a flowing current in the ground shield. Usually, this is caused by un-
earthed equipment which is connected to the chain, or the use of different power circuits. Make sure all your
audio equipment is connected to the same grounded power circuit. Do not use ground lift when it is not
necessary to ensure optimal signal quality. The default setting on your power amplifier should be set to
'Ground'.
WARNING! Please be aware that removing the ground shield of your equipment may be dangerous. The
ground shield of your signal inputs makes sure that excessive currents are eliminated and removed through
the ground shield. Removing the ground shield increases the risk of (hazardous) electrical shocks on
conducting materials such as metal microphone housings.
Output section
The rear of the D-series amplifiers is equipped with a clearly
marked speaker output section. These outputs can be connected
to the inputs of passive speakers or subwoofers (correct usage is
explained in the section Crossover information on Subwoofers
in this user manual).
The output section of the amplifier makes use of speaker-lock
connectors (two black connectors, one red connector).
Speaker-lock
The black speaker-lock connectors are used for regular speakers in a standard stereo setup and are
compatible with similar products by many manufacturers. These connectors are used for mobile use when
the connectors are inserted and removed frequently. To connect one of these plugs, insert the connector into
the speaker-lock chassis and turn it clockwise. You will hear a 'click' sound, which means that the connector
is locked in place and connected perfectly.
This kind of connector is usually equipped with 4 pins (2-pin versions are available as well), divided into +1 -
1 and +2 -2. All D-amplifiers outputs are wired at +1 -1 for each channel.
The red speaker-lock connector is used for Bridge mode, but is technically identical to the black speaker-
lock connectors.
The Bridge output makes use of two amplifier channels and combines its power to one signal output. This
makes it possible to use all of the power from one D-series amplifier to drive one full range speaker or
subwoofer (correct usage is explained in the Bridge mode section of this user manual).
The Bridge output is also wired at +1 -1.
Bridge mode
The Devine D-series amplifiers are equipped with a switch to activate Bridge mode. Also, the output
connectors of the amplifier are prepared for Bridge mode setups. Bridge mode makes it possible to combine
the power from two channels on one amplifier to provide sufficient power for one large speaker or subwoofer
(correct usage isexplained in the Crossover information on Subwoofers section of this user manual). This
way, one single power amplifier provides sufficient power for one speaker, where in normal setups, two
speakers would be connected to one power amplifier. To use Bridge mode, the switch which is set to tereo
mode by default needs to be switched to Bridge mode. Both stereo and mono inputs can be connected to the
amplifier.
Any information and illustrations shown in this user manual are subject to change without further notice.
User manual version: 4.0 Creation date + author initials: 11-12-2015 RV Revision date + author initials: 10-12-2015 RV

When using the amplifier in Bridge mode, only connect speakers through the Bridge connectors.
Crossover information for subwoofers
Please be aware that D-series amplifiers do not have an on-board crossover switch. It is therefore not
recommended to connect a subwoofer without an internal filter to the outputs of this power amplifier. Doing
so may cause damage to your subwoofer.
It is possible, however, to use an external 19-inch crossover, a D-series amplifier and a subwoofer without an
internal filter when connected in this particular order. This way, any incoming signal must go through the
crossover first which will remove any high frequencies (these will be sent to different outputs for your full-
range speakers).
The crossover output for your subwoofer will send a signal to your amplifier inputs containing frequencies
that do not exceed the level you have set. This particular small group of frequencies will be reproduced
through the D-amplifiers and sent to your subwoofer through the speaker outputs. Never cross any signals
for subwoofers higher than 300 Hz.
Impedance
The Devine D-series are tough, professional PA-amplifiers, built to deliver continuous power to your
speakers.
However, the impedance of your connected loudspeakers is very important. An impedance that is too low
may cause serious damage.
The minimum impedance of a connected loudspeaker (chain) should be no less than 4 ohms. The D-
amplifiers are not 2 ohms-stable!
This means that there should be no speaker or speaker chain connected that has a smaller impedance than
4 ohms on each side. While in Bridge mode, connect only a speaker or speaker chain with a total minimum
impedance of 8 ohms.
In stereo mode, it is possible to connect:
- two PA-speakers, each with a minimum impedance of 4 ohms and connected to one of the amplifier
channels.
- four PA-speakers, each with a minimum impedance of 8 ohms, two of which directly connected to the
amplifier (each connected to one channel), and the other two speakers connected to the first two.
In Bridge mode, it is possible to connect:
- one PA-speaker or subwoofer with a minimum impedance of 8 ohms.
Installing the amplifier
To install the D-series amplifiers in a 19-inch rack or flight case, practical
mounting brackets are provided. Mounting points are on the front panel only,
due to the fact that these amplifiers are every light in weight. Thanks to a
minimal depth of only 18 cm, the amplifiers can be installed in racks or flight
cases with a limited depth. Each D-amplifier is only 1U high.
Stacking multiple amplifiers in a 19-inch rack is possible, and the individual positions of the amplifiers in the
rack is irrelevant due to the fact that they are very lightweight. If you want to mount heavier equipment than
these power amplifiers in your rack, Devine recommends installing them as low as
possible in the rack to keep the turnover point for gravity lower, preventing the case from
tipping over.
Power input, fuse and electrical information
When it comes to power connection, the Devine D-series units are identical, and all work
with a standard IEC C14 input which can also be found on devices such as desktop
computers. The protective fuse is installed directly next to the power input, as connected
Any information and illustrations shown in this user manual are subject to change without further notice.
User manual version: 4.0 Creation date + author initials: 11-12-2015 RV Revision date + author initials: 10-12-2015 RV

power signals will transfer through the fuse first. If the fuse should blow for any reason, disconnect the device
from any power source immediately and inspect the unit before replacing the fuse. If the fuse needs
replacement, use a fuse of the same type and rating and never bridge any gaps with any other conducting
materials. Doing otherwise may cause very dangerous situations and possible (lethal) injury. Devine can not
be held responsible for any injuries or damage caused by replacing fuses with wrong types ratings or other
conducting materials.
Furthermore, there is a 115V 230V AC switch provided. The default setting on this switch is 230V AC. Do
not alter this unless you are going to connect the amplifier to a 115V AC outlet! Do not remove the cover in
front of the switch unless you have to replace it.
Ventilation and cooling
D-series amplifiers from Devine can perform all day or night without requiring any cooling-down time. After
the device has been used, it should be turned off. Due to large conventional heat sinks and a cooling fan,
these amplifiers will not overheat under normal environment conditions. There are ventilation holes
perforated in the housing of the amplifier to allow fresh, cool air to enter the amplifier and hot air to escape.
for a perfect performance, do not block any of the ventilation gaps in any way. All ventilation slots are
equipped with a layer of foam behind the slots to prevent dust, dirt and small particles such as confetti from
getting inside the unit. These also protect the amplifier and keep its internal components clean. It is
recommended to use a vacuum cleaner to clean the ventilation slots regularly for a perfect airflow.
When mounted in a 19-inch rack or flight case, ensure that there is sufficient ventilation for the power
amplifiers. Keep in mind that heat rises, and that most flight cases and racks have closed rears. Therefore, it
is always recommended to install a ventilation panel above your amplifiers so excessive heat can escape.
The installed cooling fan is temperature-controlled and will only provide optimum results when the amplifier is
functioning at full power.
It is possible to stack amplifiers directly on top of one another when mounted in a rack or as desktop stack.
No more than three Devine amplifiers should be stacked on top of one another unless there is some extra
space between every three amplifiers. This will ensure proper heat dissipation and perfect performance
during use.
Built-in protection
The D-series amplifiers are equipped with different types of protection measures to ensure they continue to
perform in optimal condition and are protected against any influences which may cause serious damage to
the internal electronics.
The following measures have been taken:
- Temperature monitoring and protection (to prevent overheating)
- Protection of electronics (to prevent possible output short circuits)
- Prevention of DC current on the outputs (DC current on your speakers may cause permanent damage)
- AC protection (fuse)
- Limiter (to prevent overloading)
- VHF distortion prevention (to prevent wireless microphone systems from interrupting the signals inside the
amplifier)
- Soft Start (to prevent a current surge when turning on an amplifier rack or stack on and causing a power
peak, which could activate your circuit breaker)

Lack of high frequencies Playback of track without high
frequencies
Try playing a different reference
track that has low frequencies
through the speaker system
Treble level set to minimum Increase Treble level to neutral
position
Too much bass Bass level set to high Decrease Bass level to neutral
position
Too much high frequency Treble level set to high Decrease Treble level to neutral
position
CLIP limiter indicator keeps on
flickering or is constantly lit
CLIP limiter circuit is active to
prevent overloading of internal
components
Decrease volume settings (signal
source, signal source on mixer
panel or master volume)
Also set Treble and Bass levels to
neutral
Protect LED is lit Protection of the internal
components and blocking the
incoming outgoing signals due to
overloading
Turn off the amplifier and check if
your speaker impedance is
correct, if the signal source is
sending an overloading signal, or if
the amplifier has been turned up ,
exceeding its maximum capacity.
Buzzing noise coming from the
speaker
Un-earthed power connection Connect the speaker to a
grounded outlet
Un-earthed signal source Connect the signal source to a
grounded outlet
Interference from power cables Avoid placing power and signal
cables in a parallel structure and
keep them as far apart as
possible. If needed, cross cables
in an X-shape only.
Bad cables Remove replace the cable or
increase decrease the volume of
the speaker. If this stops the noise,
the problem is probably located
somewhere in your signal chain.
