AKG D40 Professional Dynamic Instrument Microphone

The AKG D40 is a compact dynamic microphone engineered for close-miking drums, percussion, and amplified instruments in live and studio environments. Its cardioid polar pattern delivers focused, isolated pickup with excellent rejection of off-axis sound—ideal for cutting through dense arrangements without picking up bleed from neighboring sources. Built with a patented Varimotion diaphragm and rugged metal construction, this mic combines professional SPL handling with portability for touring musicians and recording engineers.

Audio Performance & SPL Capability

The 50–20,000 Hz frequency response and 2.5 mV/Pa sensitivity capture full instrumental detail without coloration across drums, toms, snare, and guitar cabinets. Peak output reaches 156 dB SPL at 3% THD (147 dB at 1% THD), delivering headroom for high-impact sources and close-miking applications where transient punch matters.

Build & Ergonomic Design

The metal body with dark stage blue finish measures just 104mm length × 44mm diameter, making it unobtrusive on stage or in tight studio spaces. An integrated stand adapter and H440 mounting bracket simplify positioning on drums, snare stands, or mic clips—reducing setup time without sacrificing stability or isolation.
