Sound Reinforcement Series

For recording quiet and loud sources
Earthworks® cardioid microphones are unlike all the rest, as they have patented near-perfect cardioid patterns. The sound across the entire front hemisphere is remarkably uniform and is flatter at 90 degrees than most microphones are on-axis. The SR Series have an incredible transparent sound quality, offering near-perfect polar response and high rejection of sounds at the rear of the microphone, resulting in less leakage and more gain before feedback. They effortlessly handle up to 145dB SPL while simultaneously revealing subtle details that other microphones mask. All SR models are a superb value and will provide excellent results for both live performance and recording applications.
Cardioid – 50Hz to 20kHz. The SR20 (same as the SR69) is an exceptional vocal microphone that provides pristine audio quality and more gain before feedback. Unscrew its windscreen and it is an excellent instrument microphone. It is priced to fit the working musician’s budget.
Cardioid – 50Hz to 25kHz. The SR25 was specifically designed for drums and is also ideal for a wide variety of other instruments. It’s high frequency response goes to 25kHz and costs less than the SR30. The SR25 is an integral part of our DK25/L DrumKit™ System.
Cardioid – 30Hz to 30kHz. The SR30 (same as the SR77) is the most accurate cardioid microphone on the market. With high frequency response to 30kHz it will capture incredible detail in music. It is the microphone of choice for a wide variety of musical instruments in remote and studio recording. It is also spectacular as an overhead choir microphone.
Hypercardioid – 30Hz to 30kHz. The SR30/HC (same as the SR78) offers all of the same characteristics and performance as the SR30, with a superb hypercardioid pick-up pattern. This is the microphone of choice for applications requiring the very best in audio quality and a tighter pick-up pattern where more off-axis rejection is needed.
Cardioid – 30Hz to 40kHz. The SR40 offers an extended high frequency response, extremely fast impulse response, short diaphragm settling time, exceptional cardioid polar pattern, and high rejection of sounds from the rear of the microphone. It is intended for a wide range of applications, ranging from drum overheads to miking a guitar cabinet, or as a solo microphone.
