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 (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 at each en
