Use of the amplifier
The Devine D-series amplifiers are built to last. To be able to get the most out of your speaker system, it is
recommended to read this section thoroughly, to become familiar with all the options and features of this
amplifier. Correct use of the amplifier will ensure that the expected lifespan of the amplifier remains
unchanged, as overload of this power amplifier may result in defects of 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 power
ratings. This way, you are able to select the right amplifier for any job! The D-series consist of the D-200, D400 and D-600, each with their own different power rating. The D-200 is the most affordable version, with a
relatively low power rating. This is the ideal power amplifier for speakers which do not need a large amount
of power. The most powerful version is the D-600, which can be used to power a large subwoofer in bridge
mode, or a couple of PA-speakers.
To be sure that this power amplifier can be 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 or max. 2x as powerful as needed to drive your
speakers, the amplifier is suitable. It is not recommended to use a power amplifier which is not capable of
delivering full power to drive your speakers for optimal performance.
For example, it is not recommended to drive a speaker with a 300W RMS power rating with a power amplifier
which is only capable of delivering a maximum power of 200W RMS. An amplifier with a power rating
between 300W RMS and 600w RMS would be perfect.
The reasons are:
- A more powerful amplifier does not need to perform at 100% of its capacity when the speaker is already
driven with a signal powerful enough to drive the speaker at maximum performance.
- A more powerful amplifier has more headroom when driving a speaker on its maximum level. Therefore,
peaks in the music will not cause clipping (and thus, signal distortion and possible damage when long-term
clipping exposure takes place)
- A more powerful amplifier can often be used again if you choose to purchase new speakers with a higher
maximum power rating.
- Defective speakers (often described as 'blown up') are mostly caused by power amplifiers which cause too
much signal distortion due to frequent and long-term clipping.
- Most speaker ratings are based on measured or theoretically calculated sine waves. As it is likely to play
music through your speaker system, the audio signal exists of peaks and dips in the music. Most speakers
are capable of handling certain (short-term) peaks, even when an unexpected signal peak is produced. It is
therefore safe to use a more powerful amplifier to drive your speakers.
- Clipping amplifiers can cause permanent damage to both your speakers and power amplifier. A powerful
amplifier is more likely to provide sufficient headroom and long-term exposure to excessive amplifier power
will only affect your speaker system.
How far can I turn the amplifier volume knobs?
Keep in mind that the power ratings of your speaker system and power amplifiers are mostly measured or
theoretically calculated with sine waves. As mostly music is played through your speaker system (which has
a dynamic character), you always need to monitor your speaker performance. Audio distortion may cause a
loss of signal quality and excessive power released to your speakers may cause signal quality issues and
possible permanent damage.
To be able to maintain optimal signal quality, make sure to use this checklist. This is a genuine way to adjust
your speaker system to perform at full performance, 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 which exceeds 0dB. Any higher values than 0dB will
cause signal distortion.

2. Make sure that after you checked step 1, the amplifier volume controls are carefully turned 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 of your amplifier. You need to decrease the volume level of
the amplifier channels when any of the following situations are noticed:
- Amplifier channel Clip LED lights up frequently
- Speaker produces a slight distorted sound / noticable loss of audio quality and clarity
To be sure that slight peaks in music do not affect your signal quality and performance, let your signal source
send an audio signal at +3 dB. Then, set the optimal volume control settings on your amplifier and pay
attention to your speakers and amplifiers (as described above in step 2). When your speaker system
performs on full output without audio quality issues, decrease the audio signal of your signal source back to
0dB. Now, when a slight audio peak is sent out through your signal source, it will not affect your speaker
system.
Signal source = mostly problem source!
The signal source of your system (mostly a DJ or PA mixer, or a DJ controller) is the source of audio quality
problems in most cases. This is mostly caused by improper gain structure and can be caused by excessive
input signals on your channels. Make sure to monitor every processed audio signal in your system for perfect
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 is not exceeding the 0dB point. If so,
noticeable audio quality loss and possible distortion could be present. Even when your master volume setting
does not exceed the 0dB point, it is possible that an overloaded signal is present on your channel inputs with
a gain set too high. Pay close attention to gain settings on your channel inputs and do not let the input signal
exceed 0dB as well.
Front panel
The front panel of any D-amplifier is equipped with just a few buttons
and LED indicators. This makes it possible for professionals and
amateurs to work with any of the D-series amplifiers. The front panel
has the following controls and indicators on board:
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 incomingaudio signal is noticed by the amplifier)
- Red Limiter LED (Lights up when the limiter is active and overloading of the amplifier components is
noticed)
- Blue Power LED (Power On status indicator)
Input section
The Devine D-series amplifiers is equipped with a signal input
section on the rear of the amplifier, clearly marked. This input
section is suitable for one stereo input signal, while using the input
of your choice. Examples of proper inputs are available from PAmixers, DJ mixers, DJ controllers, audio interfaces and many other
devices which provide high quality stereo line output signals. The Dseries are equipped with balanced XLR inputs, as well as balanced
6.35 mm TRS (jack) inputs. This ensures optimal quality and will
help to prevent hum and buzz noise issues.
Devine does not recommend to connect a signal source without clear volume setting display (such as an

MP3-player or smartphone) directly, as it is not possible to see if the signal is below or above the 0dB line.
However, it is possible to connect such a device to an audio mixer, to be able to see how high the outgoing
volume level of your device is set.
The inputs of this power amplifier may be used as 'signal pass' connections, to be able to connect multiple
amplifiers in a daisy chain setup. Devine recommends to link no more than three D-series power amplifiers in
a daisy chain setup, to prevent the loss of signal level and quality.
WARNING! Do not send two signal inputs to the amplifier at the same time, as the combination of two signal
inputs will drive the preamp section of the amplifier with a signal higher than allowed. Wrong use of the
inputs may cause loss of quality or even permanent damage.
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. Mostly this is caused by
unearthed equipment which is connected to the chain, or the use of different power circuits. Make sure all
your connected audio equipment is connected to the same grounded power circuit. Do not use ground lift
when not necessary to ensure optimal signal quality. The default setting on your power amplifier should be
'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 will be eliminated and removed
through the ground shield. Removing the ground shield improves 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 speaker
output section on the rear of the amplifier, clearly marked. These
outputs can be connected to the inputs of passive speakers or
subwoofers (when used correctly – explained later on 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 Neutrik
Speakon© compatible. These connectors are used for mobile use, where the connectors will be plugged in
and removed frequently. To connect one of these plugs, insert the connector in the Speaker-lock chassis and
turn the connector clockwise. You will hear a 'click', which means that the connector is locked in place and
perfectly connected.
This kind of connector is usually equipped with 4 pins (2 pin versions are available as well), divided in +1/-1
and +2/-2. The outputs for all D-amplifiers are wired on +1/-1 for each channel.
The red Speaker-lock connector is used for Bridge mode, but technically identical to the black Speakerlock connectors. Please be aware that the wiring is different!
The Bridge output makes use of the 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 (when used correctly – explained later on in this user manual).
The Bridge output is also wired on +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 be able to provide sufficient power for one large speaker or
subwoofer (when used correctly – explained later on in this user manual). This way, one single power
amplifier provides power for one speaker, where in normal setups two speakers would be connected to one

power amplifier. To use bridge mode, the switch which normally states Stereo mode needs to be switched to
Bridge mode. Stereo inputs can be connected to the amplifier, as well as mono inputs.
When using the amplifier in bridge mode, only connect speakers through the Bridge connectors.
Crossover information for subwoofers
Please be aware that the D-series amplifiers do not have an on-board switchable crossover. This means that
it is not recommended to connect a subwoofer without internal filter to the outputs of this power amplifier.
Doing so may cause damage to your subwoofer.
It is however possible to use an external 19 inch crossover, a D-series amplifier and a subwoofer without
internal filter, connected in this particular order. This way, any incoming signal must go through the crossover
first, thus removing any high frequencies from the signal (these will be sent to different outputs for your
fullrange speakers).
The crossover output for your subwoofer will send a signal to your amplifier inputs, containing frequencies
not higher than the level you have set. This particular small group of frequencies will be amplified 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 power to your speakers
continuously.
However, the impedance of your connected loudspeakers is very important, as an impedance which is too
low, may cause serious damage.
The minimum impedance of a connected loudspeaker (chain) should be no less than 4 Ohms, the Damplifiers are not 2 Ohms stable!
This means, that there should never be any speaker or speaker chain connected which has a smaller
impedance than 4 Ohms each side. In bridge mode, only a speaker or speaker chain with a total minimum
impedance of 8 Ohms should be connected.
In stereo mode, it is possible to connect:
- two PA-speakers, each with a minimum impedance of 4 Ohms, each connected to one of the amplifier
channels.
- four PA-speakers, each with a minimum impedance of 8 Ohms, whereas two speakers are directly
connected to the amplifier (each connected to one channel), the two others are connected to the first two
speakers.
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. There are only mounting points at the front
panel installed, due to the low weight of the amplifiers. Thanks to the minimal
depth of 18 cm, the amplifiers can be installed in racks or flight cases with
limited depth. Each D-amplifier is only 1U high.
Stacking multiple amplifiers while mounted in a 19 inch rack is possible, the
position of the amplifiers in the rack is not important thanks to the low weight of
each amplifier. If you have heavier equipment than these power amplifiers, it is
recommended to install them as low as possible into a rack, as the turnover
point for gravity will be positioned lower (thus preventing the case from tipping
over).

Power input, fuse and electrical information
The Devine D-series are identical in power connection, they all work with a standard IEC
input, also found on devices such as a desktop computer. The protective fuse is installed
directly next to the power input, as connected power signals will transfer through the fuse
first. When the fuse blows for any reason, disconnect the device from any power source
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 115 / 230V AC switch provided. The default setting is 230V AC, do not change 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 change the switch.
Ventilation and cooling
D-series amplifiers from Devine can perform all day or night without cooling-down time. Thanks to large
conventional heat sinks and fan cooling, the amplifiers will not overheat in normal environment conditions. To
make sure fresh, cool air is delivered to the amplifier and hot air is blown away from the fan, there are
ventilation holes perforated in the housing of the amplifier. Do not in any way block any of the ventilation
gaps, to ensure perfect performance. All ventilation slots are equipped with some foam behind the slots. This
prevents the buildup of dust, dirt and influences of small particles such as confetti inside the unit and will
keep the inside of the amplifier clean. It is recommended to use a vacuum cleaner to clean the ventilation
slots regularly, to provide a perfect airflow.
When mounted in a 19 inch flight case or rack, also ensure that there is sufficient ventilation for the power
amplifiers. Keep in mind that most flight cases and racks have closed backsides and hot air rises. Therefore,
it is always recommended to install a ventilation panel above your amplifiers, to get rid of excessive heat.
The installed cooling fan is temperature controlled and will only work at full potential when full power is
required from your amplifier.
Stacking amplifiers directly (when mounted in a rack or in use as desktop stack) is possible. No more than
three Devine amplifiers should be stacked, unless there is some included space between every three
amplifiers. This to 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 keep on
performing in optimal condition and are protected against any influence which may cause serious damage to
the internal electronics.
The following measures are provided:
- Temperature monitoring and protection (prevents from overheating)
- Electronical protection (protects from short circuits)
- DC current prevention on the outputs (DC current on your speaker may cause permanent damage)
- AC protection (fuse)
- Limiter (prevents from overloading)
- VHF distortion (prevents wireless microphone systems from interrupting the signals inside the amplifier)
- Soft Start (prevents a large amount of drawn current from your power circuit when turning a complete
amplifier rack or stack on – which could activate your circuit breaker)

Technical specifications
The Devine D-series amplifiers (D-200, D-400 and D-600) share almost the same electronic circuit. The
differences in the series are mostly the power ratings and in addition to this, the larger power supplies
installed in the devices. As the technical details are nearly identical, the table below describes the
specifications and values for all amplifiers next to each other. Some values and descriptions may be identical
