Miniature Cardioid Microphone, Lavalier

Introduction

The DPA 4080 Miniature Cardioid Microphone, Lavalier, is
specically developed to provide optimum speech intel­ligibility within broadcast, conference, and other live perfor­mances in the studio. 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 distinguish­able and improves speech intelligibility and denition.

The 4080 is delivered with a pre-mounted pop-lter in
a durable holder with an integrated shock mount, xed
on the DPA clip (g. 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 (g.

2). When mounting the holder on to the clip, a small
loop of 1.5 cm (0.6 in) (g. 3) should be left between the
microphone and the holder. Press the cable gently into
the cable trail (g. 3) and secure the cable with the cable

clamp (g. 5) Apart from securing the holder even more, it

will prevent handling noise from the cable.

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
clean the microphone as it will be damaged. Avoid all
kinds of spray or uids 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-lter is optimized to perform under difcult
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 super-uous 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.

3 pin XLR/phantom power use

If running directly into a recording system using 3 pin
XLR and phantom power, we recommend the DAD6024
XLR adapter, designed for applications when microphone
placement is on the human body.

When placing a microphone 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 provides 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 lter at e.g. 80 or 100 Hz in order to
avoid rumble from the performer. You can nd these set­tings on most wireless transmitter equipment as well as on
portable recorder units and mixing consoles.

The loop should not touch the clothes of the performer

and the cables should not touch each other.

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 (g. 6). 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 ts both left and right but­toned shirts (g. 7 & 8).

Correct use of adapters and MicroDot connectors

To provide users with safe and compact mounting of
connectors, all Miniature Microphones from DPA are
tted with the MicroDot connector. A broad range of
connection 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 (g. 9).
