“The clarity and musicality of the 100k’s gave Joe Kraemer’s score great transparency, which allowed the music to emotionally enhance the film to its fullest.”

Bruce Botnick recorded the orchestral score of Tom Cruise’s “Jack Reacher” with five Sanken CO-100K microphones

“The CO-100K mics are the perfect match for the DSD formats in which I record, which is sampled at rates up to 11.2 MHz, and has frequency response out beyond 100K.”

GRAMMY©-winner, Michael Bishop, recording the “Cancer Blows” benefit concert.

“Godzilla’s original roar in 1954 was created using a double bass and a leather glove. Using the Sanken 100K mic, we recorded the friction of a glove going across the strings to reproduce that iconic Godzilla roar”

Erik Aadahl with the e2 sound design team at Warner Bros Studios

“My main orchestral sound came from 6 Sanken CO-100Ks, an LCR tree above the conductor, and 3 rear. These mics have a phenomenal response and a texture in the top that captures that high air in a warm way.”

Grammy Award-winning Frank Filipetti recording LA Philharmonic

“We loved the sound of acoustic guitar with the CU-55, and because they are small and side-address, they work very favorably when getting them into tight spots.”

Rob Jaczko, Chair of the Music Production and Engineering Department at Boston’s Berklee College of Music.

“I’ve been messing around with the CU-55 for about a year and just fell in love with it. I’ve used it on a lot of different instruments, the mic is fairly crisp, but not unnaturally so.”

Grammy Award-winning producer/engineer Chuck Ainlay recording JD & The Straight Shot.

“The CU-55s are small and unobtrusive, but they have a wonderful low frequency response while still providing super quick transients. You get a lot of air without harshness, and a really nice deep low end.”

Grammy Award-winning Frank Filipetti recording LA Philharmonic

“The CUW-180s perform wonderfully anywhere and everywhere, I use them as a pair over the stage for ambience. Eight feet up or so, at the lip of the stage angled at 45 degrees. I also use them for ensemble sections, as a section mic it is fabulous.”

Grammy and Emmy Award-winner Rob Macomber, Chief Engineer of the Music Studios at Jazz at Lincoln Center

The Original 80’s Dual Capsule Cardioid Featuring Titanium Diaphragm Material

Faithfully pick up everything from the pulsating lows of the deepest bass instruments to the piercing highs of a coloratura soprano

Tracking a band and need a versatile microphone that can handle drums, electric or acoustic guitar, a horn section, or big vocal sound? The CU-41R captures it all, with a transparent, very detailed and truly high-fidelity sound. On a grand piano, this mic gives clarity and low-end quality like no other. A rich, male baritone resonates through the speakers with unbelievable warmth.

Unlike conventional microphones, the CU-41R houses two condenser titanium capsules vertically mounted and transformer coupled. Sanken’s original circuitry combines the outputs from the two diaphragms to provide a totally pure sound without phase distortion. The microphone has a solid cardioid pattern with low proximity effect.

The titanium capsules are impervious to humidity and temperature, providing a very stable and consistent sound. It’s not easy to produce capsules using titanium, again Sanken provides a unique solution.

Suitable for a wide variety of applications in recording, broadcasting, television and motion picture studios, the CU-41R delivers flat response from 20Hz to 20KHz. It can faithfully pick up everything from the pulsating lows of the deepest bass instruments to the piercing highs of a coloratura soprano; from the gentlest whisper to the most deafening percussive sound – without clipping. Response is uniform over the full audible frequency range.

In the 80s this mic was very popular for vocals, then it also gained popularity as a spotlight mic for orchestral and then jazz.
