AKG 2230Z28010 - Capsule for C451B (Insulating Sleeve)

AKG 2230Z28010 - Insulation sleeve for the C451 B microphone capsule

The AKG 2230Z28010 is the original insulating sleeve for the AKG C451 B condenser microphone capsule. This part, identified in the exploded view as Insulation sleeve (position 6.1 ), is part of the capsule assembly and is mounted between the high impedance elements to ensure dielectric isolation and correct spacing of the membrane-electrode system, reducing the risk of discharges, leakage and noise due to contamination. It is an indispensable OEM spare part when rebuilding or maintaining the C451 B capsule together with the complete membrane 2230M09010 and the complete electrode 2895M06010 .

Because this is a high-precision component for the capsule area, AKG recommends that replacement be performed by qualified personnel . Improper handling can damage the diaphragm or compromise the microphone's response. The 2230Z28010 ensures that, after servicing, the capsule regains the factory-designed performance and electrical stability.

Main features

• Original AKG part for the C451 B, conforming to factory tolerances and materials.
• Isolation and distancing function when stacking the capsule (position 6.1 of the exploded view).
• Compatibility verified : C451 B (including variants documented in the service manual).
• Direct integration with capsule elements: Electrode, complete (2895M06010) and Membrane, complete (2230M09010).
• Quantity per microphone : 1 unit.

Product benefits

• Safe restoration of high-impedance isolation in the capsule, essential for maintaining the specified noise level and sensitivity.
• Long-term reliability when using the exact replacement part specified by AKG in its technical documentation.
• More efficient technical service : part identified and referenced, easy to order and integrate into the repair.

Use cases

• Complete refurbishment of the C451 B capsule for studios, broadcasting and rental purposes.
• Preventive replacement when degradation of the insulating material or internal contamination is detected.
• Capsule reconstruction combining membrane (2230M09010), electrode (2895M06010) and insulating sleeve (2230Z28010).

Frequently Asked Questions

Is it a complete capsule? No. It's the insulating sleeve that's part of the capsule. For a capsule reconstruction, AKG recommends using Electrode, complete 2895M06010 + Insulation sleeve 2230Z28010 + Membrane, complete 2230M09010.

Can I install it without experience? It's not recommended. The procedure requires opening the capsule area and handling very delicate components; it must be performed by a qualified technician.
