SM81

• 20 Hz to 20 kHz frequency response
• Flat response curve for accurate reproduction of sound sources
• Low noise and high output clipping level
• Low distortion over a wide range of load impedances
• Cardioid polar pattern, uniform with frequency and symmetric about axis, providing maximum rejection and minimum coloration of off-axis sounds
• Low RF susceptibility
• Selectable low-frequency response: flat, 6 or 18 dB/octave rolloff
• 0 dB/10 dB lockable attenuator switch
• Phantom powering (DIN 45 596 voltages of 12 to 48 Vdc)
• Rugged steel construction for durability
• Field-usable over wide range of temperature and humidity conditions

SM81是专业音乐人或录音师完美的原声乐器话筒，适用于原声吉他、钢琴和铜钹等乐器扩音。 它非常适合舞台演出，但因为品质极高，也可应用于录音室。 

KSM81有何特点？

SM81拥有平直的频率响应曲线，能够精确再现声源，也能够通过低音衰减开关塑造理想的声音。 0dB/10bB可锁式衰减开关为高音量声源扩音提供更多灵活性，且心形指向性隔离主要声源，同时有效降低手持噪音。
