DTP 640 REX

Reference class dual element microphone


Thanks to variably controlled dual element technology and finely tuned frequencies, our flagship among drum microphones, the DTP 640 REX, offers unparalleled and balanced high quality sound that will delight professional drummers and sound engineers alike. The DTP 640 REX is equipped with a high quality dynamic element and condenser element – the dynamic element ensures accurate reproduction of the bass drum kick, while the condenser element optimally captures the rich low frequency sound of the drum’s shell. In order to guaranty full control over the increase in sound of the two elements, they can be separately mixed on their own channels.
In 2012, the DTP 640 REX offers two more features. The dynamic element emphasizes frequency ranges relevant for the kick drum in the ‘Dynamic Enhanced Frequency Response’ setting switchable right on the microphone, while the condenser element captures the sound neutrally.
With ‘Three settings, switchable 'Enhanced Frequency Response'’, the character of the sound can be shaped even more individually – with this setting, the condenser element focuses on frequencies from 70 to 150 Hz and delivers a full body sound. The dynamic element provides the necessary power by focusing on the range between 3 and 5 kHz.
The combination of these features with the comprehensive tonal freedom of dual-element technology greatly increases the range of use, making the DTP 640 REX into a universal tool for bass-heavy applications.
