Product overview
The NEUMANN KK 104 U bk is a premium quality cardioid condenser capsule head for compatible handheld wireless transmitters, in black: Neumann sound for wireless systems.
Its precision manufactured condenser capsule offers transparent Neumann sound, combined with the freedom of wireless operation and all the virtues of a rugged stage microphone: excellent pop protection, enormous SPL capability, suppression of handling noise and high feedback resistance. Based on Neumann's KMS series of wired stage microphones, it is designed for vocals and speech on stage and in other feedback-prone environments.

Studio quality for wireless systems
The KK 104 U is equipped with a true condenser capsule offering the clarity that made Neumann studio microphones famous, while it possesses the ruggedness required for stage use. Its tight, frequency-independent cardioid pattern ensures high gain before feedback, and its smooth frequency response and airy top end give effortless intelligibility without the usual EQ boosts.
Made for close miking
The KK 104 U is optimised for close miking: a fixed low cut filter compensates for the proximity effect and ensures clear bass, even if the singer's lips touch the microphone. The hardened steel headgrille has a highly effective internal pop screen which also keeps moisture away from the capsule, while controlling sibilance.
On stage
Designed for vocals and speech on stage and in other feedback-prone environments, the KK 104 U is suited for in-ear monitoring as well as conventional monitoring systems.
