Beyerdynamic DT-287-UNITE Specifications

APPLICATIONS

The lightweight, closed DT 297 headset has been developed for
professional broadcasting use.
The headphone features an efficient neodymium magnet system,
giving very precise reproduction and excellent intelligibility.
Another special feature is the wide frequency response of
10 - 30,000 Hz. The headsets are available with 80 Ω or 250 Ω
systems.
This headset is equipped with a condenser capsule with an extended
bass response. The microphone can be optimally positioned with
the flexible gooseneck. The optimum distance to the mouth is around
5 to 10 cm. The frequency response for this distance corresponds
to recommendations of the IRT (Institute for Radiotechnology in
Munich). The microphone holder is rotatable so that the micro­phone can be worn on the left or right side. The soft circumaural ear
pads and the fully adjustable padded headband offer a outstanding
comfort.
The cardioid polar pattern ensures high-gain-before feedback and
noise cancellation. The wide frequency response ensures clear and
precise speech reproduction and intelligibility.
All parts such as earpads, headband and gooseneck microphone
are easy to replace.
