Power Requirements
MTQG 11–52 V DC phantom power, 4.8 mA
LEMO 11–52 V DC phantom power, 5.5 mA
All specifications measured with a 48 Vdc phantom power supply. The microphone operates at lower voltages, but with slight
ly decreased headroom and sensitivity.
1 Pa=94 dB SPL
S/N ratio is the difference between 94 dB SPL and equivalent SPL of self noise, A-weighted
THD of microphone preamplifier when applied input signal level is equivalent to cartridge output at specified SPL
