The mechanical design
Types 4035, 4033, 4036 and 4037 are acoustically identical, but differ in
their mechanical design. Types 4033, 4036 and 4037 are delivered with 5m
of extremely flexible, high quality microphone cable as standard and the
Type 4035 is delivered with 3m cable. The 4037 has its cable mounted at
90o to the microphone axis, the 4036 has its cable mounted behind the axis
and the 4033 has a standard triaxial Lemo-connector for simple and safe
mounting and removal of the microphone.
Important: The Microphone will only meet its specifications
if powered correctly.

The cartridge
Types 4035, 4033, 4036 and 4037 are omnidirectional (pressure)
microphones which uses the same microphone capsule as the standard
microphones Types 4004 and 4007: A 12mm diameter prepolarized
condenser cartridge. The diaphragm is a nickel foil which has been coated
with a ultra-thin polymer layer for optimum corrosion resistance. The
microphone housing is of German silver, an alloy with a high content of
nickel to match the stable thermal qualities of the diaphragm. For optimum
stability the microphone cartridge has undergone a special pre-aging
process which releases all tensions in the materials and stabilizes the
polarization voltage.
The preamplifier
Types 4035, 4033, 4036 and 4037 use inbuilt ultra-small, thickfilm
preamplifiers with unity-gain, low noise FET-amplifier technology. The
thickfilm technology enables the microphone cartridge to be mounted on
exceptionally compact microphone housings with the preamplifiers mounted
directly behind the microphone cartridge. A circuit of passive components in
the standard 3-pin XLR connector adapts the P48 phantom powering,
separates the supply voltage from the audio signal and act as an impedance
balancing circuit for optimum noise immunity. The preamplifier has a cable
drive capability of up to 100 m after the XLR-connector (See Fig. 1 for pin
designation).
The Types 4035, 4033, 4036 and 4037 comes with an individual calibration
chart of the self noise, sensitivity and the individual frequency response.

1. Strap the microphone around the headbrace of the headphone so
the cable is also secured by the strap. Use the rubber block to
protect the cable, ensuring there is enough slack to allow the
microphone arm to be adjusted later. (see fig. 6)
2. Tighten the strap using a screwdriver.
3. Cut off any excess at the loose end of the strap.
4. Tape the microphone cable and the headphone cable together.
5. Make adjustments to the orientation of the headset unit.
6. When the headphones are worn, the microphone windscreen should
just touch the lips at the corner of the mouth (to avoid pop noise.)

Mounting the Headset Microphone Type 4035
User’s Manual

It is important to bear in mind the following points with regards to
mounting, microphone care and the use of accessories:
• The Types 4033, 4036 and 4037 are delivered in a rugged case
together with a reel for the cable. Inside the reel there is room for
both the microphone and the XLR-connector for maximum protection.
When packing the microphones, first place the microphone and the
XLR-connector inside the reel, then roll up the cable.

Care of Microphone
User’s Manual
•The microphone cartridge is tightly secured to the main body housing.
No attempt should be made to remove it. If a replacement cartridge is
required, contact your local DPA Microphones representative.
•Use of windscreen is recommended when microphones are used in dirty
or dusty environments.
•When not in use, the microphone should be disconnected and kept in
the case supplied.
