THE PRODUCT
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 DIP b4U REX OfTters two more reatures. Ine oynamic element emphasizes frequency ranges relevant tOr the kick drum in the Dynamic Ennanced Frequency Hesponse setung Switchadle rignt on the micropnone, wne the condenser element captures tne sound neutrally. With ‘Dual Enhanced Frequency Response’, the character of the sound can be shaped even more individully-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 povwer by focusing on the range between 3 and 5 kHz. he 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.

Dual Element Technology
Your DTP 640 REX is equipped with a high quality dynamic element and a 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. The enclosed DTP 40 Trs cable D connects the DTP 640 REX to two channels on your mixing board. The two channels can be mixed according to the sound quality you want.
Enhanced Frequency Response’ – EFR
The recessed EFR Slide switch (5) allows you to select different frequency
responses of the two elements.
ll= “Flat Frequency Response’ – FFR
FFR is especially suited for recording bass-heavy instruments and for placing
the DTP 640 REX outside the kick drum. With the FFR switch setting, both
elements offer a relatively neutral reproduction of sound.
=Dynamic Enhanced Frequency Response’-Dynamic EFR
Dynamic EFR emphasizes dynamic element frequency ranges relevant for the kick
drum sound. The condenser element makes the sound neutral again.
Dual Enhanced Frequency Response-Dual EFR
Dual EFR i5 especialy designed for recording kick drums. The condenser element
focuses on frequencies from 70 to 150 Hz and delivers a full body sound. The
dynamic element delivers an punchy attack by focusing on the range between 3
and 5 kHz.
Pre-attenuation level settings
You can select three settings for the pre-attenuation level by activating the
recessed sliding switch (6).
