Description
The DT 797 is a perfect combination of the closed DT 770 PRO headphone, the high-quality condenser microphone of the DT 297 headset and a new, pivoting gooseneck microphone boom. This headset has been developed especially for live performances in very loud surroundings such as sporting events etc., where ambient noise attenuation, durability and comfort are of utmost importance.
The powerful headphone systems with a frequency response of 5 - 30,000 Hz provide a perfect reproduction and a balanced sound characteristic. The noise attenuating housing and the soft, circumaural leatherette ear pads provide an excellent isolation from ambient noise. The new, pivoting gooseneck microphone boom can be set into any required position so that the microphone can be used from the right or left hand side. When not in use, the microphone can be turned to the upper position. The condenser microphone is provided with a larger capsule with improved bass response. The cardioid polar pattern ensures a high gain-before- feedback and noise cancellation. In order to avoid damages, the cables in the headband and gooseneck boom are covered. The single-sided cable provides a 6.35 mm stereo jack plug (1/4") and a 3-pin male XLR connector.
