2.3 Correct use of microphone cable
The cable is usually longer than required for its actual purpose. Ensure that superfluous cable is
wound up in soft loops (preferably 6-8 cm in diameter). Avoid ’kinks’ on the cable.
Attention: Exposing the cable to stretching beyond its specifications or stressing it by winding it
tightly over sharp edges will reduce the microphone’s operational life.
Tip: Handling noise from the cable can be decreased by up to 30dB by making a loose knot
(diameter 3-4cm) on the cable as close to the microphone element as possible.
Tip: The part where the cable enters the MicroDot connector will sometimes be exposed to
excessive stress and after long term heavy-duty use the cable might show signs of wear at this
point. As a preventive maintenance procedure it may be advisable to replace the connector in this
instance. Contact the nearest DPA Microphones representative for maintenance advice or assistance.

the Miniature Microphone. Please
note the slack after the connector.

2.2 Correct use of microphone element
The diaphragm in the microphone element is the most sensitive part of the unit and must be left
untouched to preserve its original characteristics.
Attention: Do not spray substances - e.g. hair spray
directly into the microphone.
Note: Preferably avoid make-up and paint on the
microphone element and housing, as it may be difficult
to remove later without risking particles attaching to the
diaphragm.
Tip: In lapel or tie
placement it is
recommended that
the microphone
element and grid
point away from the mouth to decrease wind noises caused by
the mouth or nose of the performer. The microphone element is
completely omnidirectional for all frequencies, so this method
will not colorize the sound.
Tip: The protection grids are available in three standard
colours: Black, beige and white. Check if a different coloured
protection grid will be less visible before painting or colouring a
microphone grid.
