USING THE KSM109
Mounting the Microphone
To secure the KSM109 to a floor stand or boom, thread the mount onto the microphone stand and insert the microphone into the mount.
Power Requirements
The KSM109 requires phantom power and performs best with a 48 Vdc supply
Note: Most modern mixers provide phantom power.
Cable Connections
Use a cable with XLR connectors at each end.
Load Impedance
Shure recommends a load impedance of at least 1000 Ω. When used with modern microphone preamplifiers rated at about 2500 Ω, the KSM109 provides higher maximum SPL capability and output clipping level. When the attenuation switch is set to the
Setting Attenuation
The attenuation switch on the KSM109 lets you reduce the signal level by up to 15 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.
0.75meters (2 feet) from sound sources such as a snare drum, or electric guitar cabinet.
