AKG 2072Z00050 - Capsule for AKG C414 B-ULS

AKG 2072Z00050 - CK12 Capsule for C414 B-ULS (Original Replacement)

AKG reference 2072Z00050 is the original CK12 capsule specified by AKG for the C414 B-ULS large-diaphragm microphone. This is the dual-diaphragm mic element that enables the 414's multi-pattern configurations and, when installed in the C414 B-ULS body, returns the system to factory-prepared performance. It is an OEM replacement part verified by the HARMAN/AKG knowledge base and technical distributors, making it ideal for corrective maintenance or refurbishing units that have lost response due to aging, dirt, or physical damage.

As a large-diaphragm CK12 capsule, its installation in the C414 B-ULS maintains the ULS (Ultra Linear Series) philosophy: an extremely flat response across the entire audible range and access to four patterns (omni, cardioid, hypercardioid, and figure-eight) from the microphone’s switches. Reference values ​​for the C414 B-ULS assembly with this capsule include 20–20,000 Hz passband, 12.5 mV/Pa sensitivity , and 14 dB-A self-noise (terminated microphone data). This part adds no features or electronics— it replaces only the acoustic capsule and requires careful installation by qualified personnel.

Frequently Asked Questions

Does this capsule change the number of microphone patterns?
No. The available patterns (omni, cardioid, hypercardioid, figure-eight) are dependent on the C414 B-ULS body; the CK12 capsule allows for this multi-pattern operation, but does not add any additional features of its own.

Does it work for other versions of the 414?
Yes for C414 EB (same CK12: 2072Z00050). For C414 B-TLII , XLS or XLII the capsule is different (see “Compatibility and Cross References”).

Can I assemble it myself?
Installation by a technician following the service manual is recommended to avoid damage to diaphragms and connections.
