You’ll love what the Earthworks SR40 high-definition cardioid mic does for your recordings and live performances. Its 30Hz-40kHz frequency response means you’re capturing a far wider range than most mics can touch. The result? Better depth and a truer sound that includes more high-frequency overtone content. You’ll also appreciate how well the SR40′s true cardioid pickup pattern rejects outside sources, and how it gives you impressive gain before feedback.
- Extended frequency response to 40kHz
- Multi-purpose directional microphone
- More gain before feedback than other microphones
- Less leakage
- Textbook perfect cardioid polar pattern with natural on- and off-axis performance
- Provides excellent results for both live performance and recording applications
- Extreme accuracy in the time domain for faithful reproduction and no smearing or distortion
- Transparent sound quality
- Shorter diaphragm settling time to prevent quieter attacks from being blurred by earlier louder attacks
- 30Hz – 40kHz frequency response, revealing subtleties in the sound that are non-existent from microphones with less high frequency range, and enabling musical performances to exhibit greater depth and realism
- The exceptional rear rejection performance enables the SR40 to easily isolate instruments in a recording or live performance setting, thus minimizing acoustic bleed
