Attention: Never attempt to loosen or tighten the connector by
the cable or its strain relief! Despite the use of Kevlar, the cable
might be damaged if twisted with excessive force.
Attention: Tighten the MicroDot using finger torque or the
recommended tightening tool only. Never attempt to use glue.
3 Miniature Microphone Headbands
3.1 Adjusting the Type 4065 Headband
The Miniature Headband Type 4065 is pre-bent for your convenience. However, it needs minor
adjustments in order
to get a tight fixed position to the back of the neck.
Carefully bend the steel tube at the areas shown on the illustration (to the left) in order to get a
tight fixed position to the back of the neck.

Do not bend this part
of the headband and
be extra careful when

2.4 Correct use of the adapters and the MicroDot connectors
To provide our professional users the possibility for a safe and compact mounting of connectors,
all Miniature Microphones from DPA Microphones are fitted with the MicroDot connector as
standard. A broad range of connection adapters are then offered as optional accessories for most
VHF and UHF systems for professional use. The adapters are ultra-compact and will in most cases
take up no more space than the original connectors.
With each adapter comes a connector-tightening
tool, which should be employed whenever the
MicroDot connector needs to be tightened safely onto
the adapter for long periods of time.
Attention: Do not attempt to mount any other
connector onto the cable than the standard
MicroDot connector from DPA Microphones.
The DPA MicroDot connector is specially designed
for use with the Kevlar reinforced cable, ensuring the
maximum possible tensile strength in the design. In
case of failures,
MicroDot spare parts, assembly tool and
assembly guide can be acquired from DPA Microphones.
Attention: Various wireless systems require use of electronic components inside the adapter to
optimise the signal level, the DC-offset filtering and powering of the build-in microphone
preamplifier. Using the adapters from DPA Microphones ensures the correct electronic circuit with
the listed types of wireless systems at all times. No attempt to employ non-standard
adapters or
connectors should be made as damage might be done to the microphone preamplifier.
Attention: Do not use non-standard MicroDot male connectors on the adapters as the female part
on the adapter might be damaged.
