AKG Acoustics D7 S, D 7 LTD manual Dépannage

D 7 LTD, D7, D7 S specifications

AKG Acoustics, a renowned name in audio technology, has made a significant impact in the world of live sound with its D7 series of vocal microphones, specifically the D7 S, D7, and D 7 LTD models. Each of these microphones boasts distinctive features and advanced technologies aimed at delivering superior sound quality, making them favorites among vocalists and sound engineers alike.

The AKG D7 series is designed to meet the rigorous demands of professional use. At its core, the D7 employs a supercardioid polar pattern, which provides exceptional rejection of background noise and feedback. This characteristic is crucial for live performances, as it ensures that the focus is on the performer’s voice, allowing for clear and precise sound reproduction. The D7's frequency response is tailored to enhance vocal clarity, with a presence boost in the critical mid-frequency range that helps vocals cut through the mix.

One of the standout features of the D7 models is the patented Laminated Microphone Capsule Technology. This technology utilizes multiple layers in capsule construction to create a unique acoustic response. As a result, the D7 delivers a naturally rich sound, capable of maintaining warmth and detail even at high sound pressure levels.

The D7 S variant introduces an added convenience with its integrated on/off switch, providing vocalists with greater control during performances. This handy feature allows artists to easily mute their microphone when not in use, minimizing the risk of unwanted noise.

The D 7 LTD edition is designed with a focus on aesthetic appeal, featuring a striking finish that distinguishes it from the standard models. While maintaining the legendary performance characteristics of the D7, the LTD version is aimed at professionals who appreciate both function and form.

All D7 microphones come encased in durable all-metal housings, ensuring they withstand the wear and tear of frequent use. They also include a robust suspension mount to minimize handling noise, further enhancing the clarity of the audio produced.

In conclusion, the AKG Acoustics D7 series, comprising the D7 S, D7, and D 7 LTD, reflects a commitment to high-quality sound and innovative design. Their combination of advanced microphone technologies, superior build quality, and practical features make them an exceptional choice for professional vocalists seeking to elevate their performance and sound experience in any live setting.
