Load Impedance
Maximum SPL capability, output clipping level, and dynamic range vary
with the input load impedance of the preamplifier to which you connect the
microphone. Shure recommends a minimum input load impedance of 1000
Ω. Most modern microphone preamplifiers meet this requirement. Higher
impedance results in better performance for these specifications.
Power Requirements
This microphone requires phantom power and performs best with a 48 Vdc
supply (IEC-61938). However, it will operate with slightly decreased head-
room and sensitivity with supplies as low as 11 Vdc.
Most modern mixers provide phantom power. You must use a balanced mi-
crophone cable: XLR-to-XLR or XLR-to-TRS.
