3.4 Retroalimentación

La retroalimentación significa que una parte del sonido emitido por el amplificador es captado por el micrófono, amplificado y devuelto a los altavoces. A partir de un determinado volumen acústico, el equipo aúlla y silba y sólo puede ponerse de nuevo bajo control reduciendo el volumen.

Para prevenir este riesgo, el micrófono tiene una característica direccional supercardioide: es lo más sensible al sonido proce- dente desde delante (p. ej. la voz), mientras reacciona apenas al sonido que llega desde los lados o desde atrás (p. ej. altavoces monitor).

La mayor seguridad contra la retroalimentación se consigue si- tuando los altavoces delante de los micrófonos, es decir, en el borde delantero del escenario.

Si se utilizan altavoces de monitor, el micrófono no debe estar orientado nunca directamente hacia los monitores o los altavo- ces de sonorización.

La retroalimentación puede ser provocada también por fenó- menos de resonancia (determinados por la acústica del recinto en cuestión), particularmente en la gama de frecuencias baja; es decir, de forma indirecta por el efecto de proximidad. En este caso basta a menudo con aumentar la distancia hacia el micró- fono para cortar la retroalimentación.

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.
