About AKG Blue Line Mic

When it comes to versatile and adaptable audio solutions, the Blue Line Series Microphone Kit, featuring the SE300B Powering Output Module and CK91 Cardioid Capsule, stands out as a top choice. This comprehensive system is designed to meet the evolving needs of the recording, broadcasting, sound reinforcement, and film industries with ease and efficiency.

The heart of this kit is the AKG SE-300B, a robust and lightweight power supply and signal output stage for the Blue Line series microphone capsules. This unit serves as the backbone of the series, supporting a variety of interchangeable capsules to adapt to changing applications. The SE-300B is engineered to maintain the integrity of the audio signal, offering a low noise floor and high output gain, ensuring studio-quality sound in every use.

To enhance audio clarity, the SE-300B features a preattenuation switch, which provides extra headroom and prevents distortion from excessively loud signals. Additionally, a low-frequency roll-off switch helps reduce noise caused by wind, ambiance, or poor grounding. This unit is powered by an external phantom power source ranging from 9 to 52 V.

Complementing the SE-300B is the AKG CK91, a cardioid capsule with signal characteristics suitable for a wide range of applications. This compact capsule boasts a flat wide frequency response from 20Hz to 20kHz, enabling smooth and accurate signal reproduction without coloration. Its cardioid polar pattern effectively eliminates off-axis noise and ambiance, minimizing feedback. This makes the CK91 ideal for spot capturing instruments and vocals for sound reinforcement and critical recording. The CK91 is powered seamlessly with the AKG SE-300B power supply.

In summary, the Blue Line Series Microphone Kit, including the SE300B Powering Output Module and CK91 Cardioid Capsule, offers a customizable, high-quality audio solution for a multitude of professional applications.
