Headsets
Headsets
HS 4VXS, HS 2S
– with cardioid (HS 4VXS) or omnidirectional (HS 2S)
microphone attached
– highest-quality pickup of speech
– HS 4VXS: effective suppression of noise from sur-
roundings
– excellent protection from vocal “popping” sounds
– The earpiece on the opposite side can be folded out
of the way of the ear.
These headsets are delivered as a complete set consist-
ing of:
– the CCM 4VXS Lg compact microphone (a cardioid
designed for extremely close pickup of speech) or
the CCM 2S Lg (omni); both have a matte gray sur-
face finish
– the HBL, a connecting rod for the microphone with
a fixed-angle suspension
– a foam popscreen B 5
– a pair of closed stereo headphones
The HCCM 4VXS Lg was developed in cooperation
with the sound engineers of a TV station who sought
the highest possible quality of sound even under the
extreme conditions of Formula 1 motor races.
A closed type of headphone was chosen to shield
the wearer from surrounding noise; it was also chosen
so that its size would accommodate the microphone.
The microphone of the HS 4VXS offers a strong bass
rolloff and a mild high-frequency boost. It is designed
for lateral sound pickup at the shortest possible dis-
tance, i.e. directly in front of the speaker’s mouth.
Proximity effect compensates for its low-frequency
rolloff such that the microphone has an even frequency
response for the person speaking, while background
noise encounters the full response rolloff and is greatly
reduced.
The microphone should be protected from vocal
“popping” noises by the use of a small, simple foam
windscreen such as the B 5; this is also recommended
for hygienic reasons.
Since the cable between the microphone and the
headset (KHS LI) is subjected to increased stress, it can
easily be exchanged if necessary.
In place of the cardioid microphone, an omnidirec-
tional microphone such as the CCM 2S Lg can be
used; the result (model HS 2S) would have lower sen-
sitivity to popping and handling noise.
For standard cable lengths and connectors, see illustra-
tion.
Other connectors (supplied by the customer) can be
installed at no extra charge if requested when ordering.
