	156 grams (5.5 oz.) (see Figure 7)
Sensitivity (typical, at 1000 Hz;	–37 dBV/Pa
1 Pa = 94 dB SPL)
Self–noise (typical, equivalent SPL;	14 dB
A-weighted, IEC 651)
Maximum SPL	145 (160, 170) dB
5000 Wload (Attenuator on)
2500 Wload (Attenuator on)	139 (154, 164) dB
1000 Wload (Attenuator on)	134 (149, 159) dB
Output Clipping Level*	15 dBV
5000 Wload
2500 Wload	9 dBV
1000 Wload	3 dBV
Dynamic Range	131 dB
5000 Wload
2500 Wload	125 dB
1000 Wload	120 dB
Signal to Noise Ratio**	80 dB

*20 Hz to 20 kHz; THD < 1%. THD of the microphone preamplifier when applied input signal is equivalent to the cartridge output at specified SPL.

**S/N ratio is difference between 94 dB SPL and equivalent SPL of self-noise A-weighted.
