SHURE 91A-X Condenser Microphone
SHURE BETA91A-X Dynamic Kick Drum Microphone
ไมโครโฟนสำหรับกระเดื่องกลอง SHURE BETA91A ชนิดคอนเดนเซอร์ Condenser (electret bias) รูปแบบการรับเสียง Cardioid เหมาะสำหรับใช้กับเครื่องดนตรีที่มีความถี่ต่ำ ตอบสนองความถี่ 20 – 20,000 Hz, Impedance 150 ohms (actual)
The Shure Beta 91A Kick Drum Microphone is designed to accurately capture the punch and attack of low-frequency instruments such as kick (bass) drums. It features a wide frequency response well suited for capturing a variety of audio signals such as organ and piano.
The flat, boundary design also aides in producing a strong, solid low-end response, as well as make it easy to mount inside of a bass drum. The Beta 91A is ideal for both recording and sound reinforcement alike.
Features:
- Uniform half-cardioid polar pattern for maximum gain-before-feedback and rejection of off-axis sound
- Precision-engineered low-profile design features integrated preamplifier and XLR connector to maximize setup efficiency while minimizing stage clutter
- Frequency response tailored for kick drum/low frequency applications with a wide dynamic range for use in high SPL environments
- Two-position contour switch to maximize attack and clarity depending on application: select the flat response setting for natural sound in most applications or the “low-mid scoop” setting for a strong low frequency “punch” with plenty of higher frequency attack
- Requires no external mounting or accessories for ease of use and storage
- Furnished with zipper pouch
