Use of t e amplifier
The Devine D-series amplifiers are built to last. To be able to get the most out of your spea er 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 spea er
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, D-
400 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 spea ers 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-spea ers.
To be sure that this power amplifier can be used safely to power the spea ers you wish to connect, pay
attention to the power ratings of your spea ers.
If the RMS power rating of the power amplifier is identical or max. 2x as powerful as needed to drive your
spea ers, the amplifier is suitable. It is not recommended to use a power amplifier which is not capable of
delivering full power to drive your spea ers for optimal performance.
For example, it is not recommended to drive a spea er 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 spea er is already
driven with a signal powerful enough to drive the spea er at maximum performance.
- A more powerful amplifier has more headroom when driving a spea er on its maximum level. Therefore,
pea s in the music will not cause clipping (and thus, signal distortion and possible damage when long-term
clipping exposure ta es place)
- A more powerful amplifier can often be used again if you choose to purchase new spea ers with a higher
maximum power rating.
- Defective spea ers (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 spea er ratings are based on measured or theoretically calculated sine waves. As it is li ely to play
music through your spea er system, the audio signal exists of pea s and dips in the music. Most spea ers
are capable of handling certain (short-term) pea s, even when an unexpected signal pea is produced. It is
therefore safe to use a more powerful amplifier to drive your spea ers.
- Clipping amplifiers can cause permanent damage to both your spea ers and power amplifier. A powerful
amplifier is more li ely to provide sufficient headroom and long-term exposure to excessive amplifier power
will only affect your spea er system.
How far can I turn t e amplifier volume knobs?
Keep in mind that the power ratings of your spea er system and power amplifiers are mostly measured or
theoretically calculated with sine waves. As mostly music is played through your spea er system (which has
a dynamic character), you always need to monitor your spea er performance. Audio distortion may cause a
loss of signal quality and excessive power released to your spea ers may cause signal quality issues and
possible permanent damage.
To be able to maintain optimal signal quality, ma e sure to use this chec list. This is a genuine way to adjust
your spea er system to perform at full performance, but without losing audio quality.
1. Ma e sure your signal source is not overdriving. When using a DJ or PA mixer, or a DJ controller with
audio interface, ma e sure it does not send a signal which exceeds 0dB. Any higher values than 0dB will
cause signal distortion.

2. Ma e sure that after you chec ed 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
spea ers and eep 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
- Spea er produces a slight distorted sound / noticable loss of audio quality and clarity
To be sure that slight pea s 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 spea ers and amplifiers (as described above in step 2). When your spea er system
performs on full output without audio quality issues, decrease the audio signal of your signal source bac to
0dB. Now, when a slight audio pea is sent out through your signal source, it will not affect your spea er
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. Ma e 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 spea er system.
Always ma e 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 ma es it possible for professionals and
amateurs to wor 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 mar ed. This input
section is suitable for one stereo input signal, while using the input
of your choice. Examples of proper inputs are available from PA-
mixers, DJ mixers, DJ controllers, audio interfaces and many other
devices which provide high quality stereo line output signals. The D-
series are equipped with balanced XLR inputs, as well as balanced
6.35 mm TRS (jac ) 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 lin 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. Ma e 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 ma es sure that excessive currents will be eliminated and removed
through the ground shield. Removing the ground shield improves the ris of (hazardous) electrical shoc s on
conducting materials such as metal microphone housings.
Output section
The rear of the D-series amplifiers is equipped with a spea er
output section on the rear of the amplifier, clearly mar ed. These
outputs can be connected to the inputs of passive spea ers or
subwoofers (when used correctly – explained later on in this user
manual).
The output section of the amplifier ma es use of spea er-loc
connectors (two blac connectors, one red connector).
Speaker-lock
The blac Spea er-loc connectors are used for regular spea ers 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 Spea er-loc chassis and
turn the connector cloc wise. You will hear a 'clic ', which means that the connector is loc ed in place and
perfectly connected.
This ind 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.
T e red Speaker-lock connector is used for Bridge mode, but technically identical to the blac Spea er-
loc connectors. Please be aware t at t e wiring is different!
The Bridge output ma es use of the two amplifier channels and combines its power to one signal output.
This ma es it possible to use all of the power from one D-series amplifier to drive one full range spea er 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 ma es it possible to combine
the power from two channels on one amplifier, to be able to provide sufficient power for one large spea er or
subwoofer (when used correctly – explained later on in this user manual). This way, one single power
amplifier provides power for one spea er, where in normal setups two spea ers would be connected to one
