0/15/25 dB Attenuation Switch Low Frequency Response Switch FIGURE 1. KSM137 GENERAL DESCRIPTION The Shure KSM137 is an end-address condenser microphone with a cardioid polar pattern. Designed for studio use, yet rugged enough for live applications, the KSM137 can withstand extremely high sound pressure levels (SPL). Its low self-noise and extended frequency response make it ideal for recording musical instruments. FEATURES A highly consistent cardioid polar pattern Ultra-thin, 2.5 m, 2

USING THE KSM137 Mounting the Microphone To secure the KSM137 to a floor stand or boom, thread the mount onto the microphone stand and insert the microphone into the microphone clip. Power Requirements The KSM137 requires phantom power and performs best with a 48 Vdc supply (IEC-268-15/DIN 45 596). It can operate on voltages as low as 11 Vdc, but headroom and sensitivity will be decreased slightly. NOTE: Most modern mixers provide phantom power. Cable Connections Use a cable with XLR connectors

Setting Attenuation The attenuation switch on the KSM137 lets you reduce the signal level by up to 25 dB without altering frequency response. This can prevent extremely loud sounds from overloading the microphone. Set the switch to the desired attenuation levels as follows: 0 dB – Move the switch to this position for “quiet” to “normal” sound levels. -15 dB – Move the switch to this position when the microphone is approximately 0.75 meters (2 feet) from sound sources such as a kick drum, snar
