Long Reach Highly Directional Mono Shotgun Microphone with Switchable Rear Rejection

The Sanken CSR-2 combines the long acoustic tube and proprietary rectangular capsule design of the CS-2 for super-sharp directivity with a unique switchable rejection of the mid and low frequency range on the side and rear. In the off position, the switch provides a wider image and a warmer room tone.

This microphone rewards you with the best of both worlds. Thanks to Sanken’s original square capsule design which optimizes space efficiency in a long acoustic tube, the CSR-2 is a unique microphone that focuses on the sound source, even at some distance.

This high degree of directionality and flexibility is accomplished by using line microphone technology for narrow-angle directivity in the frequency range and canceling background sensitivity with two capsules in the low-mid frequency range.

Rich Natural Tone with Wide-Frequency Response

This mic delivers super sharp directivity over a wide frequency range, making it the ideal microphone to capture targeted sounds in location situations with noisy surrounding ambience or in tight spaces with unwanted wall reflections. In order to reduce the sensitivity at 90 degrees off-axis, the front capsule pattern is super-cardioid. It captures the low-mid frequencies that have a longer wave-length than the acoustic tube in the rear of the microphone, with no line microphone effects.

In addition, the CSR-2 uses a second-order pressure gradient array, comprised of two microphone capsules. Their output is added to the line (front) microphone signal when the rear rejection switch is in the “on” position to suppress low frequency background sensitivity.

A rich, natural sound makes the CSR-2 ideal for a wide range of uses, such as outdoor location sound, public interviews, sports, drama, variety shows, and much more.

Innovative technology in a short 10” long (250 mm), ultra-compact 6 oz (170g) housing, this model features a uniquely long reach, extended low frequency response, and low noise. Specifically designed for event DV as well as the film and television industries, it is ideal for mounting on video and film cameras.

It is easy to maneuver on boom poles and is also effective as a handheld shotgun mic. Sharp directivity delivers highly targeted sound while eliminating background noise through off-axis rejection. Uses standard 19mm accessories. 48 volt phantom power required.

Sanken CSR-2 Shotgun Microphone at NAB 2014 – B&H

Sanken’s CSR-2 shotgun microphone, introduced at NAB 2014, features a switch for rear rejection, in order to enable expanded reach for the shotgun. The CSR-2 has two unique rectangular capsules, one to pick up audio in front and the other to reject audio in the rear. Listen to B&H’s real-world demo of this mic on the show floor, and see a roundup of Sanken’s other mics with Jim Pace from Sanken US distributor plus24.
