Acoustic features

• When compared to other handheld vocal microphones, the KMS 105 offers a superior resolution of the voice, with extended frequency response and accurate transient detail. Sibilance problems common to other handheld condenser mics are eliminated.
• No foam is used in the basket, thus eliminating any "clouding" or "muffling" of the sound.
• Also, by using a DC-polarized studio condenser capsule, all the nuances of the voice come through with subtlety, power and focus.
• The K 105 capsule was developed from the K 50, found in the KMS 150, KM 150 and KM 185 microphones. The K 105 features a supercardioid pattern, achieved by specially modifying the response of the K 50 pressure gradient transducer.
• The frequency response characteristic is developed in the acoustic realm, allowing for accurate representation of transient details found in music and speech, and thus transmitting a very "open" and detailed capture of the human voice.
• Due to the tight supercardioid polar pattern and the coloration-free off axis response, a very high level of gain before feedback is achieved.
• This polar pattern offers the highest degree of isolation while still allowing for a generous "sweet spot" in front of the microphone.

Electrical features

• The dynamic range of the KMS 105 is 132 dB, allowing reproduction of the artist’s full expression, without restraint. The maximum SPL is 150 dB and with a low self noise of 18 dB-A, a greater gain can be used without risk of adding noise to the mix.
• This way, the artist is able to use the microphone at a greater distance therefore maintaining a wide range of creative freedom during the performance.
• Because of the superior resolution and linear high frequency response, it is very easy for the artist using in-ear monitors to identify whether or not he or she is "on mic" with the KMS 105. And by employing a transformerless output circuit, this microphone can incorporate long cable runs with no loss of signal quality or high-frequency response.

The microphone basket

• Most of the available vocalist microphones rely on the attenuating effects of foam layers inside the basket. Although this is certainly a cost-effective procedure, the detrimental effects of this foam layer can be shown quite easily. Treble frequencies are attenuated, and furthermore the polar pattern can be deformed.
• These drawbacks can be eliminated by selecting open mesh constructions. With careful dimensioning and selection of different mesh sizes, excellent pop and wind attenuation can be delivered, as is well known from the standard studio-use pop screens PS 10 and PS 20, made of two layers of spaced fabric.
• In the KMS 105 a combination of four wire meshes with different mesh sizes is used. The chosen combination yields a very constant polar pattern, while maintaining the capsule’s acoustic frontal frequency response.
• Naturally, the outer microphone basket is hardened steel, due to the required ruggedness for on-stage use.

  A visit to the excellent The Beat Goes On exhibition at the Liverpool World Museum can be very enlightening for music fans...as you can even see what gear was used to record The Beatles!

• Zutons tour with beyerdynamic classic mics

  Merseyside band The Zutons recently added to the collection of classic beyerdynamic mics in their touring arsenal. With several models now forming a solid backbone in the on-stage line-up, FOH engineer Martin Mittler explains how the different mics have enhanced the band’s live sound.
