Shure Beta 98A User Manual

Power Requirements
This microphone requires phantom power and performs best with a 48 Vdc supply (IEC-
61938). However, it will operate with slightly decreased headroom and sensitivity with
supplies as low as 11 Vdc.
Most modern mixers provide phantom power. You must use a balanced microphone
cable: XLR-to-XLR or XLR-to-TRS.

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 recom-

fiers meet this requirement. Higher impedance results in better performance for these
specifications.
