Used literally once! This is a great kick mic with 2 capsules at once, dynamic and condenser.

7The  Lewitt DTP 640 REX is a high-performance, dual-element microphone designed specifically for capturing bass-heavy sources like kick drums and bass cabs. It features a dynamic and condenser capsule in a single housing, delivering the attack of a dynamic mic with the rich low-end of a condenser. 

Key Features & Specs

• Dual-Element Technology: Houses both dynamic and small-diaphragm condenser capsules, which are perfectly phase and time-aligned. [1, 2, 3]
• Dedicated Outputs: Uses a 5-pin XLR connection (via an included Y-cable) that splits into two separate standard XLR outputs so you can blend and mix both elements individually. [1]
• Switchable Sound Profiles: Built-in settings on the mic allow you to toggle between a flat frequency response, dynamic enhanced, or dual enhanced for boosted lows and high-end click. [1]
• Attenuation Pads: Includes -10 dB and -20 dB pads to accommodate extremely loud sound sources.[1, 2]

Use Cases

• Kick Drum: The go-to application. Dynamic captures the high-end "beater click" and punch, while the condenser captures the deep resonance and "boom" of the shell.
• Bass & Guitar Cabs: Often overlooked, but highly effective on bass amplifiers and electric guitars.
• Floor Toms: Performs excellently when you need that extra low-end weight on large toms. [1, 2, 3]
