AKG CK63 ULS Reference Hypercardioid Condenser Microphone Capsule
The AKG CK63 ULS is a professional small-diaphragm hypercardioid condenser capsule from the Ultra Linear Series, delivering ruler-flat response, unmatched channel separation, exceptional off-axis rejection, and high gain before feedback for broadcast and studio use with the C480 B preamp.Overview
The AKG CK63 ULS is the hypercardioid member of the Ultra Linear Series capsule family, renowned in broadcast studios and live stages globally. Its tight hypercardioid polar pattern provides unmatched channel separation and exceptional off-axis rejection — essential in multi-microphone setups where spillover between channels must be minimised. The ruler-flat frequency response ensures that what is captured is an accurate, high-fidelity representation of the source, without colouration or distortion. The CK63 ULS is designed exclusively for use with the AKG C480 B preamp module.

FAQ
How does the CK63 compare to the CK61?
Both have ruler-flat responses, but the CK63 uses a hypercardioid pattern for greater off-axis rejection and channel separation, while the CK61 is cardioid — better for wider coverage with less coloration of off-axis sound.
Is the CK63 suitable for live stage use?
Yes — the hypercardioid pattern and high gain before feedback make it well suited for live stage microphone applications.

Frequently Asked Questions
When is hypercardioid better than cardioid in a recording studio?
Hypercardioid patterns provide tighter isolation than cardioid, making the CK63 ULS ideal for miking individual instruments in tight studio setups or separating drum kit components (kick, snare, toms) with minimal bleed.
What does exceptional off-axis rejection mean for studio and broadcast use?
The CK63 ULS heavily attenuates sound arriving from the sides and rear, allowing you to position it close to a drum or horn without picking up loud sounds from adjacent instruments—essential for detailed multi-track recording.
How does the CK63 ULS support unmatched channel separation in stereo recording?
When using a pair of CK63 ULS capsules in stereo (e.g., as drum overheads), the tight hypercardioid patterns prevent cross-channel bleed, giving you a more focused stereo image and better individual track control in the mix.
What is high gain before feedback, and why is it useful?
High gain before feedback means the capsule can be positioned closer to a monitor or speaker before it squeals, enabling more flexible microphone placement in live broadcast and live recording applications.
Is the CK63 ULS compatible with the C480 B preamp?
Yes; the CK63 ULS is engineered for the C480 B preamp and requires its phantom power and amplification for proper operation.
How do ruler-flat response and a tight polar pattern work together?
Ruler-flat response gives you accurate tone, while the hypercardioid pattern isolates that tone from nearby sources, allowing engineers to capture clean, detailed individual instrument tracks.
What is the typical lead time for the CK63 ULS through Procure.ae?
Contact Procure.ae to confirm current stock and delivery timing for this reference-grade hypercardioid capsule and compatible C480 B system components.
Does Procure.ae stock preamps and cables for a complete CK63 ULS recording setup?
Yes; Procure.ae supplies the full ecosystem of AKG professional recording equipment for UAE and GCC studios—reach out to discuss a tailored multi-capsule or complete system.
What is included in the CK63 ULS package?
You receive the hypercardioid small-diaphragm capsule; the C480 B preamp, mounting hardware, cables, shock mount, and windscreen are ordered separately.
Can I use two CK63 ULS capsules as a matched stereo pair?
Yes; the CK63 ULS is often used in matched pairs for overhead drum recording, stereo instrument miking, and tight stereo ambience—contact Procure.ae about stereo pair availability.
What warranty and technical support apply to the CK63 ULS?
Contact Procure.ae for warranty coverage, regional support, and repair options for this professional small-diaphragm capsule.
