Description
The Shure RPM89/PRE replacement XLR preamp works with VP89S, VP89M, and VP89L end-address shotgun condenser microphones.
The VP89 is a professional shotgun microphone for use in critical A/V media production applications. Shure's premium modular shotgun microphone offers superior preamplifier design with RF immunity for pick-up of audience response, talk shows, and concerts. The microphone includes a low-cut filter switch, narrow pickup angle, and unmatched off-axis rejection.
Features
• Class A, discrete preamplifier provides transparent, extremely fast transient response with no crossover distortion and minimal harmonic and intermodulation distortion
• Selectable low-frequency response
• Lightweight, compact design accommodates prolonged operation, minimizing operator fatigue attributed to many shotgun microphones
• Aircraft-grade aluminum alloy construction resists wear and abuse
• Operates over a wide range of temperatures and humidity
• Switchable Polar Pattern (Hypercardioid / Lobar)
• Requires phantom power and performs best with a 48 V DC supply
