Introduction
The DPA d:screet™ Miniature Microphones are designed for
use with wired or wireless systems in theater, film, television,
conferences and instrument close-miking applications.
To ensure optimal performance of your d:screet™ Miniature
Microphone, please follow the simple care and maintenance
instructions below. Our d:screet Miniature Microphones are
designed to be resistant to humidity and moisture. Highly resist-
ant materials like gold plated stainless steel, and features like the
double-vent protection system, ensures that you avoid damage
by fluids. Keep your d:screet Miniature Mics away from water
and cleaning fluids, and keep the microphone element dry at all
times.
Cleaning guide
The cable and protection grid are the only parts that may be
cleaned. Do not use any kind of cleaning fluid other than demin-
eralized water. Avoid all kinds of spray or fluids containing chemi-
cal components to remove static electricity on or close to the
microphone as this could cause damage to the electret layer.
When mounting a d:screet Miniature Microphone directly on or
close to the skin of a performer, care should be taken to avoid
sweat from running into the microphone. If the microphone has
been exposed to sweat, it must be rinsed out in demineralized
water and left to dry out to recover its original specifications.
Drying out the microphone between exposures to humidity will
also help to extend its lifetime. If the microphone gets filled up
with water it will not be damaged, but possibly turn deaf while
the water is captured inside the microphone, behind the pro-
tection grid. Remove the water by shaking the microphone or
drying it with a piece of lint free cloth.
Cleaning the microphone grid
During use in environments where the microphone is exposed to
makeup or dusty materials, the grid may get clogged up. Remove
the microphone grid from the microphone element (not applicable
to SC4071, SCO71-H and 4080) and clean the grid using a soft
cloth and demineralized water only. Make sure the grid is dry before
re-mounting it on the microphone housing. For SC4071, SCO71-H
and 4080 (which do not feature removable grids) cleaning the grid
is done using a soft cloth and demineralized water.
Cleaning the microphone cable
Residue from tape, glue, or makeup on the cable must be re-
moved after use. Leaving these substances on the cable over
longer periods of time may etch into the cable jacket and will
make the cable more susceptible to breaks. The cable can easily
be cleaned using organic oil (e.g. olive oil) or lukewarm, dem-
ineralized water. Do not bend the cable or rub it harshly since
this may stress the inner cores of the cable and cause them to
break over time.
Microphone grids
The d:screet Miniature Microphones (SC4060/61/62/63 and
SCO60/61-H) are supplied with two dierent grids for acoustic
equalization, depending on the placement on the performer; a
soft boost grid (pre-fitted) giving a 3 dB soft boost at 8-20 kHz.
Alternatively, the high boost grid for chest mounting gives ap-
proximately 10 dB boost at 12 kHz. Without any grid mounted,
the microphone is linear, but unprotected against dirt.
The d:screet Miniature Microphones with presence boost
(SC4071 and SCO71-H) and the 4080 have a fixed presence
boost grid. These types are pre-equalized to provide optimal
speech intelligibility when using chest placement.
Mounting
Several mounting accessories are specially designed to mount,
place or conceal the d:screet Miniature Microphones. Refer to
www.dpamicrophones.com/dscreet for an up-to-date selection

4080
Special for the 4080 is that it is delivered with a pre-mounted pop-
filter in a holder with an integrated shock mount, fixed on the
DPA clip (fig. 1). The 4080 is designed to be always used in this
setup. When mounting the holder on to the clip, a small loop of
1.5 cm (0.6 in) (fig. 2) should be left between the microphone and
the holder. Press the cable gently into the cable trail and secure the
cable with the cable clamp (fig. 3). To ensure the optimal sound of
the 4080, the best position on the performer’s body is 20 - 25 cm
(8 – 10 in) from the speaker’s mouth (fig. 4). With its innovative
mounting solution it can easily be turned in all directions, upwards
and sidewards, to get the best sound. Furthermore, it ensures that
the 4080 fits both left and right buttoned shirts.
Microphone element
The diaphragm in the microphone element is the most sensi-
tive part of the unit, and must be left untouched to preserve its
original characteristics. Do not spray any substances such as hair
spray directly into the microphone and avoid getting makeup or
paint on the microphone element and housing.
Correct treatment of the microphone cable
The cable is usually longer than required for its actual purpose.
Make sure that superfluous cable is wound up in soft loops (pref-
erably 6 – 8 cm (2.4 – 3 in) in diameter). Avoid kinks in the cable.
Handling noise from the cable can be reduced significantly by
making a loose cable loop, as close to the microphone element
as possible.
Correct use of adapters and MicroDot connectors
To provide users with safe and compact mounting of connec-
tors, all our d:screet Miniature Microphones are fitted with the
MicroDot connector. A broad range of adapters is oered as
optional accessories for most wireless systems for professional
use. Never attempt to loosen or tighten the connector by the
cable or its strain relief. Some wireless systems require the use
of electronic components inside the adapter to optimize the
signal level, the DC-oset filtering, and powering of the built-in
microphone preamplifier.
Always use the adapters from DPA Microphones with the wire-
less systems to ensure the correct electronic circuit. Do not use
non-standard adapters or connectors as you might damage the
microphone preamplifier.

Miniature Cardioid Microphone, Lavalier,
Introduction
The DPA 4080 Miniature Cardioid Microphone, Lavalier, is
specifically developed to provide optimum speech intel-
ligibility within broadcast, conference, and other live per-
formances in the studio or in the field. To ensure optimal
performance with your 4080, please follow these simple
instructions for use, placement, and cleaning.
Correct use of 4080
The 4080 is designed to be mounted on the body of a
speaker. It is acoustically pre-equalized, offering a 4 dB
presence boost, which makes the voice more distinguish-
able and improves speech intelligibility and definition. The
4080 is delivered with a pre-mounted pop-filter in a
durable holder with an integrated shock mount, fixed
on the DPA clip (fig. 1). The 4080 is designed to be
always used in this setup and it is recommended not to
dismount it when not in use. If necesssary, the holder can
easily be mounted or dismounted from the clip (fig. 2).
When mounting the holder on to the clip, a small loop
of 1.5 cm (0.6 in) should be left between the microphone
and the holder. Press the cable gently into the cable trail
(fig. 3) and secure the cable with the cable clamp. Apart
from securing the holder even more, it will prevent han-
dling noise from the cable. The loop should not touch
the clothes of the performer (fig. 4). The cables should not
touch each other.
clean the microphone as it will be damaged. Avoid all
kinds of spray or fluids containing chemical components
to remove static electricity on or close to the microphone
as this could cause permanent damage to the electret
layer. The pop filter is optimized to perform under difficult
conditions, but should it need cleaning, distilled water will
wash away any dirt.
Use organic oil (e.g. olive oil) or lukewarm, distilled water
to remove residue from tape, glue, or make-up from the
cable after use. Use organic oil after cleaning to protect the
cable sleeve and prolonging its life.
Ensure that superfluous cable is wound up in soft loops
(preferably 6-8 cm (2.5 – 3 in) in diameter) which also
helps to reduce handling noise. Do not bend the cable or
rub it harshly, it may stress the inner cores of the cable and
cause them to break over time.
Correct use of adapters and MicroDot connectors
To provide users with safe and compact mounting of
connectors, all Miniature Microphones from DPA are fitted
with the MicroDot connector. A broad range of connec-
tion adapters is offered as optional accessories for most
VHF and UHF systems for professional use. A connector
tightening tool is supplied with each adapter and is the
only recommendable way to tighten the MicroDot (fig.
9).
3 pin XLR/phantom power use
If running directly into a recording system using 3 pin
XLR and phantom power, we recommend the DAD6024
Placement of 4080
To ensure the optimal sound of the 4080, the best posi-
tion on the performer’s body is 20-25 cm (8 – 10 in) from
the speaker’s mouth (fig. 6). With its innovative mounting
solution it can easily be turned in all directions, upwards
and sidewards, to get the best sound. Furthermore, it en-
sures that the 4080 fits both left and right buttoned shirts
(fig. 7 & 8).
Cleaning guide
Miniature Microphones from DPA are designed to be very
resistant to external stress. Highly resistant materials are
used in construction of the microphones. Do not try to
XLR adapter, designed for applications when microphone
placement is on the human body. When placing a micro-
phone on a performer’s chest, an acoustic lower midrange
boost will occur resulting in a muddy and indistinct sound,
compared to a free frontal placement. The adapter pro-
vides a 3 dB attenuation at 800 Hz for added clarity when
using the 4080 lavalier.
When using lavalier microphones it is always advisable to
insert a high-pass filter at e.g. 80 or 100 Hz in order to
avoid rumble from the speaker. You can find these settings
on most wireless transmitter equipment as well as on port-
able recorder units and mixing consoles.
