  • 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.


    • Exceptionally narrow directivity with optimum reach
    • Suppresses background sensitivity using Sanken's exclusive rear cancellation technology
    • Proprietary rectangular capsule design for compact, super-sharp directivity
    • Flat frequency response 70Hz to 20 kHz
    • Easy to handle and operate using 48V phantom power

    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.

    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 €œon€ 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.
