The HS 4VXS is a
headset microphone for mounting to Beyer headphones of the DT 100 series
(for
example VXS Lg). Other headphones are also suitable. The HS 4VXS consists
of:
- the compact microphone CCM
4 VXS Lg (cardioid for extremely close pickup)
- a mounting plate with a fixed-angle bent tube microphone mount
- a foam-type popscreen B 5 (also the small foam cover B 1 can be used)
The HS 4VXS was developed
in collaboration with sound engineers of a TV station who demanded the
highest quality sound transmission even under the extreme conditions of
Formula-1 motor races. A closed-back headphone type has been chosen in
order to shield the speaker from environmental noise. This headset microphone
has been designed for much higher sound quality than is available from
typical subminiature microphones. The first users of the HS 4VXS
were willing to accept a higher weight in order to achieve the highest
sound quality.
The microphone has a substantial
bass roll-off and a slight high-frequency boost. It is designed for lateral
pickup close close to and immediately in front of the speaker's mouth.
Its bass roll-off is compensated by the close pickup (proximity effect).
Thus, except for the high-frequency boost, the microphone has a flat frequency
response for the speaker while it has a severe bass roll-off for all sound
coming from a greater distance. This attenuates the transmission of background
noise when compared to the speaker's voice.
The HS 4VXS can be easily
mounted to either the left or right side of the headphones. Since the
cable may be subjected to mechanical stress during use, it is connected
by way of a Lemo plug. This allows the cable to be replaced easily if
it should break. The microphone should be protected against popping by
a small standard foam-type windscreen such as the B 5 or the B 1. This
is recommended also for hygienic reasons. Instead of the cardioid CCM
4 VXSL, the CCM 2 SL (omni with slight high-frequency boost) can also
be used. The bent tube is also available separately, and bears the type
designation HB-L.
