CU-31 and CU-32
High Input SPL
High Transient Response
Compact Condenser Mics

Small, high-resolution condenser microphones designed for music recording. The CU-31 and CU-32 capture sound beautifully, from quiet nuanced performances to loud bombastic explosions.

A high transient response allows for the superb broadcast or recording of percussion, cymbal sounds and woodwind instruments.

They also feature 6dB higher sensitivity than conventional microphones. As a result, they are suited for cleanly capturing such explosive, high pressure sound sources as trumpets and drums, particularly in tight spaces.

CU-31 Maximum sensitivity: On-Axis
CU-32 Maximum sensitivity: Side-Firing

Two Compact Mics Delivering a Natural, Uncolored Sound

Wide number of applications for various kinds of musical instruments

The Sanken CU-31 and CU-32 are small, lightweight microphones for all recording applications. Delivering a natural, uncolored sound, they feature Sanken’s original Push-Pull type capsule design, which gives them increased sensitivity.

In addition to their high maximum SPL of 148dB at 1%THD, they offer a very flat frequency response ( 20Hz to 18,000Hz ).

Unique to Sanken microphones, these mics come with a light, strong, corrosion-free one-micron titanium diaphragm, therefore ensuring the mic is immune to changes in temperature and humidity. And you can choose from the on-axis CU-31 or the CU-32 with a side-firing pattern.

Consequently these are very practical and proven microphones. The CU-31 and CU-32 are especially renowned for their quality and for their reliability.
