Frequently Asked Questions
What is the Blue Line Series, and what makes it suitable for live broadcast?
The Blue Line Series is AKG's professional modular condenser line for field broadcast and portable live sound; the CK91 cardioid capsule delivers broadcast-grade signal in a compact form factor ideal for news crews and touring productions.
How does the smooth and well-balanced frequency response support live broadcast?
A neutral frequency response prevents on-air tonal surprises and EQ artifacts, ensuring that announcers, reporters, and talent sound consistent across different microphone positions and broadcast sessions.
What does consistent cardioid pattern mean for a rotating live talent?
A stable cardioid pattern across all frequencies ensures that as a speaker turns their head or moves slightly, the microphone tone and feedback margin remain predictable—critical for live news and sports broadcasting.
Which AKG preamp does the CK91 require?
The CK91 is engineered for the SE300 B preamp, which provides phantom power, amplification, and phantom-powered wireless transmitter compatibility for broadcast field operations.
What is Modulock bayonet coupling, and why does it matter?
Modulock is a fast-connect bayonet-style coupling that allows field crews to swap capsules in seconds without tools, enabling quick reconfiguration between cardioid, omnidirectional, and hypercardioid configurations during a broadcast day.
Is the CK91 suitable for both on-camera and off-camera broadcast use?
Yes; the compact cardioid capsule works equally well as a lavalier, handheld reporter mic, or desk-mounted interview microphone, making it versatile for studio and field broadcast applications.
What are typical lead times for the CK91 from Procure.ae?
Contact Procure.ae to confirm stock availability and delivery timing for Blue Line Series capsules and compatible SE300 B preamp systems.
Does Procure.ae stock the SE300 B preamp and wireless transmitter integration?
Yes; Procure.ae supplies Blue Line broadcast systems for UAE and GCC media organizations—reach out to discuss a complete broadcast microphone setup.
What is included in the CK91 package?
You receive the cardioid condenser capsule and the W90 windscreen; the SE300 B preamp, cables, transmitter adapters, and mounting hardware are sourced separately.
Can multiple CK91 capsules be used interchangeably with one SE300 B preamp?
Yes; the Modulock coupling allows instant swapping, letting a single preamp support multiple Blue Line capsules (cardioid, omnidirectional, hypercardioid) throughout a broadcast shift.
What warranty does the CK91 include?
Contact Procure.ae for warranty period, coverage scope, and regional technical support for broadcast-grade Blue Line Series capsules.
