The KMS 104, KMS 104 plus, and KMS 105 microphones were specifically designed to provide optimal sound reproduction for the human voice in challenging live performance situations on stage. These microphones are globally recognized as the industry standard for high-quality stage microphones. With their high acoustic resolution and linear frequency response, performers can expect the best conditions for their work on stage. The low self-noise and uncolored sound of the KMS microphones allow for seamless integration with personal monitoring systems.
The KMS 104 and KMS 104 plus models have a cardioid polar pattern that effectively reduces rear sound. The KMS 105 features a supercardioid polar pattern, providing even greater suppression of off-axis sounds within a 180° hemisphere. Compared to the KMS 104, the KMS 104 plus offers enhanced low-frequency response and has been specifically optimized for female rock and pop vocals through collaboration with professional musicians and practical testing. This way, users can choose the microphone that suits their specific application area best.
Acoustic Characteristics:
The KMS series microphones utilize studio-grade condenser capsules, enabling them to accurately reproduce every nuance of the human voice. Unlike other stage microphones that are predominantly dynamic, the KMS series microphones provide high acoustic transparency, an extended frequency range, and more accurate transmission of the frontal signal. Carefully tuned acoustic filters and transformerless impedance converters allow the microphones to handle high sound pressure levels without distortion, even in the presence of strong gusts and explosive sounds. Sibilant and whistling sounds are naturally reproduced, which is a characteristic feature of condenser microphones. Additionally, the design of the acoustic filters enables the microphones to maintain their polar patterns even in the low-frequency range, offering protection against feedback when used near acoustic systems on the stage.
Electrical Characteristics:
To compensate for the proximity effect that occurs when vocal microphones are placed close to the sound source, the KMS series microphones use electronic circuits with corresponding capsule characteristics. The microphones also have low-cut filters with a fixed cutoff frequency of 120 Hz for attenuation in free field. The maximum sound pressure level of the KMS series microphones is 150 dB. With a low self-noise level not exceeding 18 dB-A, higher sensitivity can be used when working with the microphones. This allows performers to hold the microphone further from their mouth, providing greater freedom of movement on stage, which is crucial for artists. The transformerless output stages ensure the transmission of microphone signals over longer cables without any loss in quality.
The Legendary Sound of Neumann:
The KMS 104 brings studio-grade vocal microphone quality to the stage. Its precision condenser capsule delivers the true Neumann sound combined with the durability of a stage microphone. The KMS 104 offers excellent wind noise protection, low handling noise, high sound pressure level capability, and effective feedback suppression due to its narrow cardioid pattern. Unlike regular stage microphones that use dynamic capsules, the KMS 104 is equipped with a genuine condenser microphone capsule, providing superior clarity that has made Neumann studio microphones famous worldwide.
The KMS 104 can withstand sound pressure levels of up to 150 dB without limitations and its narrow, frequency-independent cardioid polar pattern ensures high gain before feedback occurs. Compared to dynamic microphones, the KMS 104 has a smoother frequency response and pronounced high frequencies. It also exhibits superior transient response characteristics, resulting in clearer and more emotional vocal sound. The microphone is easy to handle and does not require aggressive equalization, further enhancing its feedback resistance. The KMS 104 is optimized for close microphone use, compensating for the proximity effect and providing clean bass even when the singer's lips touch the microphone. The microphone's basket is made of hardened steel and has an effective internal anti-slip screen to prevent moisture and protect the capsule.
The transformerless circuit minimizes electromagnetic interference, while the microphone's low output impedance of 50 ohms allows for long cable runs of up to 300m without any loss in transmission quality. The KMS 104 is primarily designed as a portable vocal microphone but can also be used for other stage applications such as drums, saxophone, trumpet, trombone, harmonica, acoustic guitar, and guitar combo amplifiers, thanks to its high sound pressure level capability and wide dynamic range. Its excellent sound quality also makes it suitable for home recording and broadcasting. When used in untreated spaces, the KMS 104 captures a sufficiently dry sound with minimal room effect, which is a significant advantage.
Mechanical Specifications:
Stage microphones require a robust design, and the KMS 104, KMS 104 plus, and KMS 105 feature thick-walled metal housings to provide effective protection against structural noise. The microphones have protective grilles made of strong steel wire that can be easily unscrewed for cleaning the acoustic filters.
