Over 90 years of technological innovation and artist feedback have gone into the design of this unique microphone. No other manufacturer includes the features of the CU-51. What you hear in the studio is what you capture in the control room. The CU-51 offers a new dual-capsule design pioneered by Sanken, providing an exacting cardioid pattern ideal for vocals and a wide range of musical applications. The CU-51 also has a very low proximity effect making vocals and instruments seem bigger than life.
A very special characteristic of the CU-51 is its ability to maintain uniform response in both on-axis and off-axis positions. It is common knowledge that varying the direction of a microphone will change the frequency response and tone.
The tone and response of the CU-51 remains consistent through changes in the axis angle while maintaining the benefits of a large capsule design. The CU-51’s frequency response is truly flat at 90 degrees, essential in maintaining sonic transparency.
The CU-51’s specially designed double capsule has one diaphragm that is optimized for low frequencies, while the other one captures the higher frequencies with guaranteed phase coherency between the two capsules in a meticulously engineered microphone that achieves totally transparent high-resolution results. The PPS (Polyphenylene) membranes are immune to the effects of humidity and temperature change, resulting in consistent response, regardless of the recording environment.
The CU-51 consistently delivers a high transient, natural and uncolored sound with vivid sonic imagery.
