Sanken Chromatic CU-55

CU-55 A Great All Purpose Small Premium Quality Cardioid Mic


 Sanken Chromatic CU-55

Featuring a modern, compact design, the CU-55 provides a rich vintage sound in a small, lightweight, easy-to-position package. It is a great, affordable, all-purpose mic.

The CU-55 houses a side-firing 16mm capsule. Designed with a resonant chamber like the top-of-the-line CU-44X MK II, it has been tuned to create a perfect cardioid pattern and is omnidirectional below 50 kHz.

Small Mic Packs A Powerful Punch

Affordable premium quality mic perfect for all instruments, acoustic, electric, and percussion, in addition to vocals

This new generation microphone is flat even at 90 degrees, flat on the axis, with very little proximity effect. The CU-55 uses the same diaphragm material as Sanken Chromatic’s remarkable CU-100 and CUW-180 mics. Ideal for acoustic instruments like guitars, cello, harp, and piano, the CU-55 can also handle the explosive levels of big brass and pounding tympani. Try it on a snare drum, it fits nicely into tight spaces.

It features a built-in resonant chamber that mates with the capsule to optimize pattern and minimize proximity effects. Stereo pairs are truly matched.

The affordably priced CU-55 is a fitting addition to the Sanken line of fine studio microphones. The response is very warm and natural sounding, very musical, without any coloration or artificial boost. If you are wrestling with some high SPLs, have no fears – the little CU-55 can handle whatever you throw at it. It can also bring out the best in softer, subtler sounds, and as a compact side-address microphone, it is very easy to maneuver into tight spaces.

Like all Sanken microphones, the CU-55 provides optimum quality audio and reliability and is a solid investment for the ambitious recording engineer/producer.
