Introduction
Thank you for purchasing the Devine DM 20 dynamic microphone kit. This kit consists of a microphone,
mounting clip and cable, and is designed for live vocal applications. The DM 20 kit can be connected directly
to a mixing board, audio interface, powered speaker or similar device.
The DM 20 microphone is a dynamic microphone which does not require phantom power. Thanks to its
super-cardioid, uni-directional polar pattern, it is suitable for live applications where feedback loops can often
occur. The specific polar pattern of the DM 20 means that nearly all sound is captured from the front of the
microphone. The sides and rear of this microphone are less sensitive (as shown in the polar pattern graph in
the Technical specifications section of this user manual.)
This DM 20 microphone is an ideal vocal partner on stage, especially when using wedge floor monitors. To
prevent feedback loops, floor monitors are best placed to the left and/or right of the vocalist due to this
microphone's sensitivity and polar pattern. This is explained in more detail in the Positioning the
microphone section in this user manual.
The sensitivity of this type of microphone is much lower than a condenser microphone, which is beneficial for
preventing feedback loops. It is essential, however, that the vocalist (presenter, singer, etc.) uses proper
microphone techniques. This user manual provides you with tips on how to make the most of this Devine
microphone.
The DM 20 is equipped with an ON/OFF switch so the user can manually turn the microphone off when it is
not in use. This is practical for MC's and hosts who keep the microphone with them at all times. By being
able to mute the microphone directly, the settings on the mixer or speaker do not need to be continually
adjusted.
The DM 20 is designed for use on the road thanks to its robust housing and sturdy grill, which protects its
components from potential damage by impact or falls. The DM 20 is equipped with an integrated foam
windshield behind the grill, which not only eliminates a lot of external noise, it also prevents moisture from
getting into the internal electronics.

Using the microphone
The Devine DM 20 dynamic microphone is suitable for live vocal applications. Thanks to the uni-directional
polar pattern, most of the sound is captured from directly in front of the microphone and not from the rear or
sides, which keeps feedback loops to a minimum.
IMPORTANT: Phantom power
This dynamic microphone can be connected to a mixing console or similar device which is capable of
delivering +48V phantom power. Even though the DM 20 is a dynamic microphone, it does not require +48V
phantom power to operate, but exposure to phantom power will not harm it in any way.
Connecting the cable
The Devine DM 20 comes with a microphone cable of approximately 3
metres long. It features a male and a female 3-pin XLR connection. One
end of the cable fits into the DM 20 microphone connector and the other
can be connected to a mixing console, for example.
The DM 20 microphone and included cable are equipped with a locking
mechanism. When the cable is connected to the microphone, an audible
'click' can be heard. That means the cable has locked to the microphone
connector and can not fall off. When you want to remove the cable from
the microphone, press the locking tab on the connector and gently pull it
loose.
The other end of the cable is compatible with most mixing boards that have 3-pin XLR connectors for
microphone inputs. If this is not the case with your mixer, and your microphone input is a jack connector, for
instance, you can use an XLR-to-jack adapter. You can also extend the cable with a separately available
XLR male – XLR female cable.
Positioning the microphone
Please note that the Devine DM 20 is a dynamic microphone with a uni-directional polar pattern (supercardioid) and is less sensitive than a condenser studio microphone. This can be beneficial during live
performances when there is a variety of different sounds and volumes on stage. The lower sensitivity and the
specific polar pattern of this microphone keep feedback loops to a minimum. Feedback loops are usually the
result of microphones being placed too close to speakers. The sound the microphone picks up from the
speakers is amplified and played back through these speakers, which is then captured by the microphone,
and so forth. This infinite loop can only be eliminated by feedback destroyers or by simply positioning the
microphone further away from the speakers.
During live applications, feedback loops often occur when wedge floor monitors are positioned without
paying attention to the characteristics of the microphone being used. When using a cardioid microphone, for
example, most of the sound is captured from directly in front of the microphone and some from the sides. It is
therefore ideal to place a wedge monitor in front of the vocalist (on the floor), in a direct line from the
microphone.
Because the DM 20 is a dynamic super-cardioid microphone, some sound is also captured from the rear of
the microphone. Therefore, placing a wedge monitor directly in front of the microphone, facing the vocalist, is
not recommended. Because the DM 20 doesn't pick up much audio from the sides, it would be better to
place one or two wedge monitors slightly to the left and/or right, facing the vocalist.
Using the microphone clip
The DM 20 also comes with a practical microphone stand clip for placing the microphone on a stand. This
clip is flexible and will hold the microphone firmly in place. Gently slide the microphone into the clip until the
ON/OFF switch is level with the opening on the clip. Do not attempt to force the microphone any further into
the clip, as this will not improve functionality and could cause the clip to break.
The microphone clip is equipped with 5/8” thread, which is compatible with most microphone stands. If your

stand differs, you may need a 3/8” (inner thread) to 5/8” (outer thread) adapter. These are available at your
local dealer.
Using the switch
The DM 20 is equipped with a practical ON/OFF switch and features a screw to adjust the switch tension.
Usually, the switch tension setting is high, so it can not accidentally be turned off or on.
Protecting the microphone:
This Devine microphone is equipped with sensitive electronics which provide optimal audio performance.
Make sure the microphone is not exposed to situations that may cause permanent damage as a result of
severe impacts, collision, or falls from high altitudes. Improper use of the microphone is not covered by
warranty. Always transport the microphone in the original packaging, or in a flight case with a fitted foam
inlay.
Connecting the microphone to a mixer or audio interface:
This microphone uses a 3-pin XLR to connect to a mixer or audio-interface (cable included). It is
recommended to check the following settings on your audio equipment before connecting the microphone:
Mixer/Audio interface:
- Gain is set to 0
- Compression/lo-cut set to 'Off' or neutral
- EQ set to neutral
- Pan/Balance set to neutral
- Volume fader or potentiometer set to the lowest possible position
Microphone:
- Make sure the microphone is stable and securely inserted into the included clip, or hand-held.
- Position the vocalist directly in front of the microphone as close as possible, and ensure proper microphone
technique is used.
Set the volume parameter (potentiometer or fader) to ‘0 dB’ for the best possible audio performance.
Gradually increase the gain until slight clipping or distortion is audible (usually indicated with a (LED) VU
meter or LED). Use your mixing console to apply EQing or other effects as desired.
