AKG D40 Professional Dynamic Instrument Microphone
Description
AKG D40 Professional Dynamic Instrument Microphone
The AKG D40 is a compact, lightweight dynamic microphone purpose-built for capturing guitar rigs, drums, and percussion on stage and in the studio. Its ergonomic 104mm body and integrated stand adapter clamp securely to amplifiers and hardware, delivering tight, controlled pickup with minimal handling noise—essential reliability for touring and live gigging.
Design & Build Quality
Built tough with a metal body finished in distinctive dark stage blue, this microphone tips the scales at just 245g and measures 104mm in length with a 44mm diameter—small enough to position precisely on a guitar cabinet or drum without cluttering your rig. The patented Varimotion diaphragm uses unique laminated material to tame harsh high-frequency peaks and maintain smooth tone, while the wire-mesh cap shields the transducer from road knocks and dust.
Audio Performance & Specifications
The cardioid polar pattern locks onto your source and rejects bleed from the rest of the stage, crucial for keeping your guitar tone isolated in a loud band mix. Peak handling reaches 156 dB SPL at 3% THD, and the 50–20,000 Hz frequency response with 2.5 mV/Pa sensitivity captures every nuance of your playing without added coloration or artifacts.

Frequently Asked Questions
Is the D40 suitable for vocal recording?
No, the D40 is engineered specifically for instruments and percussion. Its tight, focused character and reduced proximity effect make it less ideal for vocals; consider a microphone voiced for vocal warmth instead.
What instruments does the D40 work best on?
The D40 excels on drums, percussion, guitar cabinets, and amplified instruments where isolation and high SPL handling are priorities. It is not recommended for close-miking unplugged acoustic guitars.
What comes included with the D40?
The microphone includes an integrated stand adapter and H440 mounting bracket, allowing you to mount it on a snare drum, tom, amp cabinet, or microphone stand right out of the box.
How does the D40 compare to the Shure SM57?
Both are cardioid instrument mics, but the D40 features AKG's patented Varimotion damping diaphragm for tighter high-frequency control and slightly higher SPL headroom (156 dB vs. SM57's 132 dB), making it better suited for extremely loud sources and reducing feedback in dense live settings.
Can the D40 handle very loud sources without distortion?
Yes, the D40 handles up to 156 dB SPL at 3% THD and 147 dB at 1% THD, making it one of the highest-SPL dynamic mics available. It is ideal for close-miking kick drums, power amplifiers, and other hot sources in live and studio work.
