Recomendam-se os seguintes esquemas de conexão:

Circuito com transformador de entrada com derivação central (isolado da terra):

Circuito com transformador de entrada sem derivação central (isolado da terra):

Valores normalizados para Rv (ou 2 x 2):

Val.	Rv	2 x Rv
12 V ± 2 V	330 Ohm	680 Ohm
24 V ± 2 V	680 Ohm	1200 Ohm
48 V ± 4 V	3300 Ohm	6800 Ohm

Por razões de simetria as resistências 2 x Rv poderão possuir uma tole- rância de 0,5 % no máximo.

Se as entradas dos amplificadores estiverem ligadas à terra ou se não houver transformadores de entrada, deverão ser inseridos na linha áudio ou condensadores ou transformadores adicionais para evitar que as eta- pas de entrada possam ser prejudicados por correntes de fuga.

C 4000B specifications

The AKG Acoustics C 4000B is a sophisticated large-diaphragm condenser microphone, recognized for its exceptional versatility and sound quality. It is a popular choice among musicians, sound engineers, and recording studios, widely appreciated for its ability to handle a variety of sound sources with transparency and warmth.

One of the main features of the C 4000B is its multi-pattern capability, allowing users to switch between cardioid, omnidirectional, and figure-8 polar patterns. This flexibility makes it suitable for a range of applications, from solo vocal recordings to capturing ensemble performances. The ability to modify the pickup pattern enables the microphone to excel in various environments, adapting to different acoustic conditions and recording setups.

The microphone boasts a frequency response of 20 Hz to 20 kHz, ensuring it can capture both the deepest lows and the finest highs. This wide frequency range is particularly beneficial for nuanced applications such as vocals, acoustic instruments, and room ambiance. The C 4000B also includes an internal pop filter, which helps mitigate plosive sounds, enhancing the clarity of recordings.

Equipped with a high SPL handling of up to 150 dB, the C 4000B can easily capture loud sound sources, making it a reliable choice for miking guitar amplifiers, brass instruments, and drums. The microphone's low self-noise level ensures that it delivers pristine sound quality, crucial for professional recordings where interference needs to be minimized.

The build quality of the C 4000B reflects AKG’s commitment to durability and performance. The microphone features a robust metal housing that can withstand the rigors of both studio and live environments. This durability is complemented by a shock mount that reduces vibrations and handling noise, further contributing to the microphone’s overall performance.

In terms of technology, the AKG C 4000B utilizes a dual-diaphragm design that enhances the microphone's sensitivity and transient response. This design allows for a more dynamic and accurate representation of the sound source, providing an open and airy quality that is highly sought after in studio recordings.

Overall, the AKG Acoustics C 4000B is a well-engineered microphone that combines versatility, build quality, and superior sound performance, making it an essential tool for professionals and enthusiasts alike. Whether used in a studio or a live setting, the C 4000B stands out as an exceptional choice for capturing sound with precision and clarity.
