Product Description
The AKG D 7 delivers the subtle, open, detailed sound of a condenser microphone, while maintaining the rugged reliability and ease of control of a dynamic microphone. At the heart of the D 7's design is AKG's new Laminate Varimotion diaphragm which allows precise response tuning without resonators. Thanks to the Laminate Varimotion diaphragm, the D 7 delivers beautifully-detailed sound, amazing response consistency at any SPL and absolutely incredible gain-before-feedback. The D 7 always sounds "right" even on the loudest stages.
The D 7 features a built-in high-pass filter that cuts out unwanted low frequencies, minimizes handling noise, and provides superior audio clarity and intelligibility. AKG's newest dynamic microphone also features a humbucking coil that greatly reduces interference from electrical devices, ensuring that only pure vocal sounds come through.
The D 7 features a super-strong, heavy-duty die-cast chassis with a thick, dent-resistant grille screen that can easily handle the inevitable accidents that happen in live performances on the road. The mic is also equipped with a gold-plated XLR-type output connector for loss-free signal transfer.
The AKG D 7 is a reference-quality dynamic microphone offering complete control for singers and speakers, leading to a better listening experience for audiences. Its precise, detailed sound quality, high gain-before-feedback, low handling noise, and road-tough reliability ensure its presence on stage with leading performers.
The European-built D 7 is backed by a two-year parts and labour warranty from AKG.

Diagram Descriptions
Frequency Response Chart
A graph illustrating the microphone's frequency response from 70 Hz to 20,000 Hz. It shows a relatively flat response across the mid-range, with a peak sensitivity around 5 kHz, and a gradual roll-off at higher frequencies. A low-frequency roll-off begins around 80 Hz, indicating the effect of the built-in high-pass filter.
Polar Pattern Charts
Multiple charts depict the microphone's directional pickup patterns at different frequencies: 125 Hz, 250 Hz, 500 Hz, 1 kHz, 2 kHz, 4 kHz, 8 kHz, and 16 kHz. These charts confirm a supercardioid pattern, characterized by strong directivity at the front and significant rejection of sound originating from the sides and rear (approximately 180 degrees).
