Capturing acoustic instruments accurately requires microphones that offer a stable frequency response and controlled directional characteristics. The ECM-B9750UL45-201 electret microphone element is designed to meet these requirements, providing consistent and reliable performance for studio recordings, live performances, and portable setups. Its compact size of 9.7 × 5 mm allows for close placement to instruments without obstructing the performance or interfering with recording quality.
To address the real-world challenges of acoustic recording, such as ambient noise, room reflections, and spill from nearby instruments, the ECM-B9750UL45-201 features a balanced frequency response and unidirectional design to reduce interference while preserving the instrument’s natural character.

Frequency Response and Sound Characteristics
Within its frequency range of 100 Hz to 16 kHz, the microphone provides a smooth and even response. Lower frequencies are stable and controlled, avoiding boominess or muddiness, which is particularly beneficial for small string instruments such as violins, violas, and cellos. Midrange frequencies are natural and clear, ensuring accurate reproduction of the instrument’s core tones. Higher frequencies exhibit a gentle lift, capturing overtones and subtle harmonic details to enhance the brightness and clarity of recordings. Overall, the microphone offers a balanced sound that faithfully represents the instrument’s natural timbre.
Directional Characteristics and Noise Rejection
The directional characteristics also play a key role in capturing clear audio. The unidirectional (cardioid) pattern significantly reduces sounds coming from the sides and rear, helping to minimize interference from other instruments and environmental reflections. Slight additional attenuation in certain frequency regions further suppresses off-axis sound, which is especially useful in ensemble or multi-instrument recording settings. This focused pickup pattern allows engineers and musicians to capture the target instrument with greater precision while minimizing unwanted noise.
Applications in Instrument Recording
In practical use, the ECM-B9750UL45-201 is well-suited for a variety of acoustic instruments, including small strings, woodwinds, and light percussion. Its compact design enables close placement to the instrument, allowing detailed capture without affecting performance. It is also ideal for portable recording or close-miking scenarios where space is limited, providing consistent and reliable sound reproduction across different recording environments.
