Decreased CO-100K

from Wikipedia, the free encyclopedia

The Sanken CO-100K is a condenser microphone from the Japanese microphone manufacturer Sanken Microphone .

The CO-100K was released in 2004 and is the first microphone with a frequency response of 20–100,000  Hz that was specially developed for use in sound recording rather than for measurement purposes .

It was developed by Sanken, in cooperation with the scientific and technical research department of the Japanese national broadcasting company, the NHK , and is part of the Sanken Chromatik series of studio microphones.

application

Initially, the microphone was used for traditional classical and ( Broadway ) theater recordings. Today the CO-100K is often used in recording studios as drum overhead and for recording grand pianos or in the Decca Tree microphone arrangement for orchestral recordings.

With a frequency response of up to 100,000 Hz, the CO-100K can also be used for recording original sound , Foley , Dolby Atmos and for sound effects , especially for sound design in the film and video game industry.

Technical specifications

The manufacturer specifies the frequency response of the microphone with a value of 20–100,000 Hz. The course of the frequency curve in the range of around 20-10,000 Hz is relatively linear, with minor deviations.

Since the CO-100K was designed for music recording, the frequency curve is not entirely flat. From around 16,000 Hz the frequencies are increased and from 50,000 Hz there is an increase of 20 deciBel , which Sanken describes as a "bump". This frequency response enables sound events in the high frequencies (over 10,000 Hz) to be recorded in detail despite the greater distance between the sound source and the microphone. This allows a Nahmikrofonierung be dispensed with (close miking).

Since sound waves develop a directionality in parallel with increasing amplitude , Sanken recommends pointing the microphone towards the sound source despite the spherical directional characteristic .

The sensitivity (Sensitivity) is nominally 1 kHz at 39.8  mV / Pa (−28 dB, 0 dB = 1 V / Pa); the maximum permissible sound pressure level is 125  dB SPL .

The weight of the microphone is 150 g.

equipment

The CO-100K is supplied with a vinyl cover, the KS-100 swing mount, the information sheet on the measurement results and the manual. The AC-100 aluminum case container and the KS-UNI swing bracket are available separately.

Awards

  • 2005: The CO-100K was awarded “One of the best devices at the exhibition” at the AES NY trade fair .
  • 2008: The CO-100K was awarded the "Technical Development Prize of the Acoustical Society of Japan".
