FAQ
Q: Can other AKG Blue Line capsules be fitted to the C391 B?
A: Yes — the SE300 preamplifier body accepts the full range of AKG Blue Line Series capsules for different polar patterns and sound characteristics.
Q: What is the difference between the flat, 75 Hz, and 10 dB pad settings?
A: The flat setting provides full-range output; the 75 Hz roll-off reduces low-frequency rumble and proximity effect; the 10 dB pad attenuates the output for high-SPL sources.

Frequently Asked Questions
What is the difference between a small-diaphragm and large-diaphragm condenser microphone in broadcast recording?
Small-diaphragm condensers like the C391 B have a tighter, more directional pickup and faster transient response, making them ideal for isolating individual sound sources in busy broadcast environments. Large-diaphragm models capture more room ambience.
How does the CK91 Blue Line capsule enhance broadcast audio quality?
The CK91 Blue Line is optimized for critical speech and vocal recording, providing clarity and presence in the midrange. This is ideal for broadcast news, interviews, and announcements where intelligibility is paramount.
What does the SE300 preamplifier contribute to the C391 B microphone performance?
The SE300 preamplifier provides low-noise amplification and stable gain, ensuring clean audio even in demanding broadcast settings. The combination of the CK91 capsule and SE300 electronics creates a broadcast-grade microphone.
How does the switchable bass roll-off filter help in field broadcasting?
The bass roll-off removes wind noise, traffic rumble, and handling noise common in outdoor broadcast environments. This keeps the recorded voice clean and focused without requiring heavy post-processing EQ.
What is the interchangeable capsule system, and how does it extend the microphone's utility?
The C391 B supports swappable capsule modules, allowing you to adapt the microphone for different recording tasks. Additional CK capsules are available for specialized applications, making the C391 B a future-proof investment.
Is the C391 B suitable for outdoor field reporting, or must it stay in a studio?
The C391 B is explicitly designed for demanding broadcast applications including field reporting, location recording, and outdoor events. Its robust construction, switchable bass roll-off, and compact size make it ideal for mobile journalism.
