The Sanken CU-41 (Used) is a professional large-diaphragm condenser microphone in used condition, designed to deliver extremely faithful and natural sound reproduction. Born from a collaboration between Sanken and the Japanese public broadcaster NHK, it remains one of the most innovative achievements in the world of studio microphones thanks to its exclusive dual-capsule technology.

Dual-Capsule Technology for an Extremely Linear Response

At the heart of the Sanken CU-41 is an exclusive Two-Way Capsule system, an extremely rare solution in the world of condenser microphones. Two independent capsules operate simultaneously:

• a small-diameter capsule dedicated to high frequencies;
• a large-diaphragm capsule responsible for low and mid-low frequencies.

The two signals are internally combined into a single mono output with a 1 kHz crossover, resulting in an extremely flat and consistent frequency response across the entire sound spectrum.

Titanium capsules for maximum stability

Both capsules use 1-micron titanium diaphragms, a design that makes the microphone particularly resistant to changes in temperature, humidity, and material aging.

This construction ensures consistent performance over time and high reliability even in the most demanding recording environments.

Ideal microphone for vocals, broadcast, and acoustic musicSanken CU-41 used for professional vocal recordings

Thanks to its extremely neutral frequency response and pure cardioid polar pattern, the CU-41 is particularly well-suited for:

• vocal recording;
• voice-overs and dubbing;
• radio and television broadcasting;
• film productions;
• orchestral ensembles;
• acoustic instruments and piano.

The microphone’s distinctive linear response is not limited to the on-axis direction but remains very uniform even off-axis, providing a natural reproduction of the environment and sound sources.

Professional construction by Sanken

The microphone body features a refined Satin Nickel finish and is equipped with a transformer-balanced output, a solution prized for its musical sound character and high reliability.

The microphone comes with a Rycote shock mount.
