Earthworks Audio
Looking to capture acoustic instruments, guitar cabinets, and choir sections with lifelike, studio-grade detail? The Earthworks SR30 is a professional cardioid condenser microphone engineered to deliver an ultra-wide 20Hz–30kHz frequency response with unbelievable impulse speed and dynamic clarity.
Capture the absolute pinnacle of acoustic realism, transparency, and detailed dynamics with the Earthworks SR30 Cardioid Instrument Microphone. Designed for elite studio tracking and demanding live stages, this high-definition small-diaphragm condenser microphone pairs an ultra-wide frequency response up to 30kHz with a lightning-fast impulse response, delivering true-to-life audio capture for instruments, percussion, and ensembles.
Why Choose the Earthworks SR30?
Standard instrument microphones often color off-axis sound or struggle to keep up with rapid, explosive transients. The Earthworks SR30 redefines expectations by utilizing a near-perfect cardioid polar pattern coupled to a dedicated transformerless preamplifier. It provides exceptional, uncolored rejection of sounds arriving off-axis, ensuring maximum gain-before-feedback on loud stages and pristine multi-mic isolation in dense studio environments. Whether tracking delicate acoustic guitars or powerful grand pianos, the SR30 offers an open, three-dimensional sonic window.
Key Performance Features
- Extended 20Hz to 30kHz Frequency Response: Captures the entire audible spectrum alongside extended high-frequency air and detail with absolute linearity.
- Lightning-Fast Impulse Response: Swiftly tracks rapid transients, percussive hits, and intricate dynamic shifts without smearing.
- Uniform Cardioid Polar Pattern: Maintains consistent directional characteristics across all frequencies, eliminating phase anomalies when blending multiple mics.
- High SPL Handling: Safely manages up to 139 dB SPL, making it robust enough for close-miking horns, drums, and high-output amplifiers.
- Low Output Impedance & Transformerless Design: Ensures transparent signal transfer over long cable runs without signal degradation.
- Individual Calibration Chart: Each microphone comes packaged with its own custom-measured frequency response curve.
