 The
Type 4065-BL is the black version of the headband mounted condenser
microphone Type 4065, bent to sit on the left side of the face. This type
uses a prepolarised omnidirectional cartridge element with a 5.4 mm
vertical diaphragm, which is acoustically identical with the cartridge
used in Type 4061. It is specially designed for maximum performance under
the often difficult conditions when mounted directly on the human body.
The band is easily bent to fit any head shape, in a tight fixed position.
Special attention has been paid in the design to the humidity problems
that often occur in theatrical applications and to the light weight
construction of the headband itself. A double vent protection system, a
drop stopper on the tube together with water resistant materials inside
the microphone, make it more than difficult for the humidity to cause the
Headband Microphone to fail. The sensitivity is 6 mV/Pa to match the level
of the human voice to the general input sensitivity of most wireless
transmitters.
If powered correctly the microphone will be able to handle sound pressure
levels up to 144 dB SPL before clipping occurs. A wide range of connection
adapters makes it possible to use the headband with close to any
professional wireless system available plus 48 V phantom.
Type 4065 is excellent for on-stage use as well as in the studio.
