With a frequency range of 50–20,000 Hz and a sensitivity of 52 dB, the AKG D40 Blue delivers a clear, full-bodied sound that reproduces low-end fundamentals and crisp highs, making it well suited for guitars, brass, and percussion.

The D40 is a wired studio microphone featuring a robust metal housing and a mini XLR (3-pin) interface for secure connections. Its output impedance of 2000 Ω and input impedance of 600 Ω ensure reliable matching with consoles and preamps.

Safety and interference control are supported by low RF power of 2.5 mW, and the wired connectivity guarantees consistent signal quality during performances or recordings. The included carrying case simplifies transport and protects the microphone between sessions.

Typical use cases include close-miking acoustic and electric guitar cabinets, miking brass and woodwind instruments, capturing percussion elements, and spot-miking on stage or in the studio. Its tonal balance and durability make it a reliable choice for engineers and performers alike.

Key selling points include the wide 50–20,000 Hz frequency response, 52 dB sensitivity, solid metal housing in blue, mini XLR connectivity, and the included carrying case for secure transport.
