Small Size Microphone
  • CU-31:Cardioid Condenser Microphone (Axis Direction)
  • Small size, easy to set
  • Wide number of applications for various kinds of musical instruments
  • Beautiful cardioid pattern, and frequency response not only on-axis but at other angles

Small, high-resolution condenser microphones designed mainly for music recording, the CU-31 and CU-32 capture sound beautifully, not only for a full orchestra but also in solo musical instrument performances. A high transient response allows the
superb broadcast or recording of percussion, cymbal sounds and woodwind instruments.
The Sanken CU-31 and CU-32 are small, lightweight microphones for TV / radio broadcasting and studio recording. Delivering a natural, uncolored sound, they feature Sanken's original Push-Pull type capsule design, which gives them sensitivity 6dB higher than conventional microphones of the same size. As a result, they are particularly suited for cleanly capturing such explosive, high pressure sound sources as trumpets and drums. In addition to their high maximum SPL of 148dB at 1%THD, the CU-31 and CU-32 offer a very flat frequency response ( 20Hz to 18,000Hz ). Like all Sanken microphones, these mics come with a light, strong, corrosion-free one-micron titanium diaphragm which is immune to changes in temperature and humidity. These are very practical, proven microphones. The CU-31 and CU-32 are especially renowned not only for their quality, but for their reliability.
