Sensitivity Changes vs. Phantom-Power Voltage

The CM-150 has different sensitivity at different phantom voltages. If you use phantom powering other than 48 volt, change the printed sensitivity of your unit by the amount shown in the right hand column below.

For example, if the sensitivity on your printout is 11 mV/Pa, and you are using the mic with 24-volt phantom, the correct sensitivity is 11-2.1 or 8.9 mV/Pa.

Phantom	Change in
	Printout Sensitivity
48 V	0 mV
(6.8K resistors)
24 V	–2.1 mV
(1200 ohm resistors)
18 V	–2.6 mV
18 V center tap trans-	–0.6 mV
former such as in PH-1A
12 V	– 3.6 mV
(680 ohm resistors)
