Introduction
All the d:fineTM Headset Microphones provide a uniquely natural and open sound. Ultra-lightweight and adjustable, d:fineTM Headset Mics ensure a secure and comfortable fit in live performance environments. To ensure optimal performance of your d:fine Headset Mic, please follow the simple instructions below.
Placement of microphone
For discreet placement, you can bend the microphone boom slightly so that the
cap-sule is as close to the cheek as possible. Do not hold the capsule while
bending; bend the wire boom, making a smooth curve with your thumb to best fit
the profile of the face.
Mount a directional mic 2 – 3 cm (1 in) from the corner of the mouth to ensure
optimal sound quality compared to an omnidirectional mic that can be placed
further away from the mouth.
Omnidirectional characteristics
- The microphone is sensitive to sound from all directions.
- The sound remains more or less the same regardless of the distance between the sound source and the microphone.
- The positioning of microphones with omnidirectional characteristics is less critical than with directional.
- An omnidirectional microphone is generally not very sensitive to wind, breathing and handling noises
Directional characteristics
-
Rejects background noise and creates higher separation.
-
The microphone is most sensitive to sound on the side of the chevron.
-
The positioning of mics with directional characteristics is essential as the low-frequency level will change according to the distance to the mouth.
Choose a distance that yields the desired amount of bass. -
Care should be taken to protect against wind and pop noise e.g. by using a windscreen.
How to tell the difference between d:fineTM Headset Microphone capsules
Adjusting the d:fineTM 4065
4065 is pre-formed but may require adjustment in order to get a tight, fixed
position to the back of
the neck. Adjust the steel tube carefully at the curves.
A protection grid is mounted over the microphone head. If clogged with dirt or
make-up,
gently remove it and clean it with distilled water.
Adjusting the d:fineTM 4066, 4067, and 4088
The size of the headset mount can easily be adjusted. Change the standard bend
by carefully expanding
the distance between the ear hooks.
To change sides, simply click the boom out of the clips and switch it over to
the other side.
The remaining two clips are not used. The soft cable must not be attached into
the clips.
Adjusting the d:fineTM Omnidirectional, d:fineTM Directional, d:fineTM 66
and d:fineTM 88.
The directional characteristics of the microphone is indicated on the flat
microphone head with for omnidirectional and for directional as shown on page
3. This marking should always point towards the mouth. Mount a directional
headset 2 – 3 cm (1 in) from the corner of the mouth to ensure optimal sound
quality.
For the single-ear, just open the spring hook lightly, first place the slide
behind your earlobe (Pic. 1) and let go of the spring over your ear (Pic. 2).
For the dual-ear, place the headset behind your ears and place the springs
like for the single-ear. Adjust the headset mount by pulling or pushing the
wires until it fits tight (Pic. 3). The relief is pre-mounted with dual-ear
headsets and supplied with single-ear.
Correct placement behind the earlobe
See instruction video at
dpamicrophones.com/dfine
Position the microphone properly by pulling or pushing the boom along the slide.
Switch between left and right ear wearing style simply by rotating the microphone boom. Hold on to the earhook while gently turning the boom.
For the dual-ear versions, also rotate the two earhooks.
Adjust the microphone boom to follow the shape of your face by gently bending the soft steel on the cable hanger.
Adjust the angle of the cable run, also by gently bending the soft steel (see arrows). Position the cable as shown on the picture forsecuring the position of the microphone.
The cable relief on the dual-ear version should be fixed in the clip that also holds the two wires on the mount.
Always leave the protection grid on the d:fine Omnidirectional and d:fineTM Directional, as it protects the inner grid and offers protection against wind and breathing noise. The protection grid is replaceable.
Service connector for exchange of cables or booms on the d:fineTM
Omnidirectional, d:fineTM Directional,d:fineTM 66 and d:fineTM 88
These d:fineTM Headset Microphones offer exchange of cables or microphone
booms. Simply locate the service access
point, pull back the small protection cap and gently pull the boom away from
the cable hanger.
Windscreens
The enclosed windscreens offer additional protection against wind and pop
noise. Gently draw the windscreen over the microphone head.
For even better protection, bigger windscreens are available.
Sweat stop
The microphone is equipped with a transparent sweat stop around the microphone
boom to prevent sweat running along the microphone boom to the microphone
head.
Accessories (see more at
www.dpamicrophones.com)
Grids and windscreens, cables and adapters, booms and earhooks.
Protection cap
The d:fineTM Omnidirectional and d:fineTM Directional microphones come with a
red plastic cap which serves to protect the microphone head when putting on
make-up, hairspray and more.Remove the cap before use.
Color codes & cable steer
The d:fineTM Omnidirectional and d:fine Directional microphones come with a
number of cable steer clips in different colours. Mounted on the cable relief,
this clip allows for quick recognition of a specific headset microphone.
Clothing clip for d:fineTM Omnidirec-tional, d:fineTM Directional, d:fineTM
66 and d:fineTM 88.
The supplied clothing clip allows you to attach the cable to your clothes,
thus relieving the cable draw to the headset mic. This is essential on the
single-ear headset mic.
Correct use of microphone grids
The two different protection grids that are supplied with 4066, 4067, and
d:fine66 are for acoustical equalization, depending on the placement on the
performer. Remove the premounted soft boost grid before replacing it with the
high boost grid.
Cleaning the mic grid of d:fineTM 4065, 4066, 4067 and d:fineTM 66
Remove the microphone grid from the microphone element and clean the grid
using a soft cloth and distilled water only. Make sure the grid is dry before
remounting it on the microphone element. This is not possible on the 4088 and
d:fineTM 88 as the diaphragm is protected inside the microphone housing and
the protection grids are not removable. Therefore, no attempt should be made
to clean the grid surface and extreme care should be taken not to clog the
grids with makeup e.g.
Cable maintenance
The cable is usually longer than required. Make sure that superfluous cable is
wound up in soft figure-of-eight loops (preferably 6 – 8 cm (2.5 – 3 in)
diameter) and avoid kinks in the cable.
Use organic oil (e.g. olive oil) or lukewarm distilled water to remove residue
from tape, glue, or make-up on the cable. 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.
General Maintenance
The d:fine Headsets are resistant to high levels of humidity. However, care
must be taken to keep the headset microphone away from exposure to water and
cleaning fluids, and to keep the microphone head dry at all times. Do not use
spray or use fluid-containing chemicals that could remove static electricity
on or close to the microphone. This could cause permanent damage.
MicroDot connectors and adapters
To provide users with safe and compact mounting of connectors, all headsets
from DPA are fitted with the MicroDot connector as standard. A broad range of
connection adapters is offered as optional accessories for most wireless
systems for professional use. See
www.dpamicrophones.com/adapters
Use the supplied connector-tightening tool whenever the MicroDot connector
needs to be fastened to the adapter for long periods of time.
