The KS3 tube microphone system

The KS3 microphone has a hand built true pressure transducer with an all tube transformerless 
amplifier. The KS3 condenser microphone system is three-dimensional and transparent, has a 
fast impulse response and is absolutely phase correct.

The extremely thin pure aluminium diaphragm of this newly designed capsule is 1" in  diameter. 
This one of a kind capsule gives the KS3 a very unique and desirable sound.

The polar pattern of the KS3 is omnidirectional with a slight directionality in the high frequencies. 
Its small rise over 2kHz gives it a very natural sound. The microphone capsule has a solid and 
very flat frequency response down to the lowest frequencies.

Due to its unique design the KS3 is able to pick up the entire dynamic range and timbre of an 
orchestra. Therefore it is also well suited for recording acoustic instruments such as piano, 
acoustic guitar or violin. The KS3 is very well suited as a single overhead microphone on 
drum kits.

The KS3 is built to a very high standard.  With a very low self noise of 14 dB-A, more gain can be 
used without risk of adding noise to the final product.  The dynamic range of the KS3 is 132 dB 
(extended dynamic range is 159 dB SPL) allowing faithful reproduction of all musical expression.  
This microphone is able to accept sound pressure levels of up to a maximum of 173 dB, which 
corresponds to an effective sound pressure of 8934 Pa. That means you can record anything with 
this mic!

The all tube amplifier of this microphone allows for extremely fine reproduction of low level signals 
and low frequency information. Also, long cable runs can be used with no loss of signal quality.  

Similar to the RS1 and the VS2 the output can be either line level or microphone level.  Due to the 
line level output it is not necessary to use a mic pre-amp, but you can use a microphone preamp 
by adjusting the output level. With the gain adjustment in the power supply it is possible to drive line 
level recording equipment or A/D converters directly to ensure the highest quality audio without any 
loss. This unique gain control is accomplished by changing the capsule polarization voltage.   
Changing the gain results in no change in sound.

The KS3 has an integrated shock mount, that makes the mic very easy to handle. You don`t have 
to be afraid of the mic falling out of the mount!  

We only use handselected nonmicrophonic original German made NOS Special Quality longlife 
tubes.  

The capsule is temperature stabilized to make it suitable for outside recordings.  The housing, 
power supply and shock mount are made of solid milled high-grade steel.

The KS3 itself and all important parts of the microphone are all built in Germany! We are proud 
that even the entire capsule is designed and produced in our laboratory.  

There is a 5 year warranty.
