Power
The PZM11, PZM11LLPP and PZM11LLWRP can only be powered by Phantom Power.

The PZM11LL and PZM11LLWR can be powered by 24VAC or by 12 to 24VDC.

*The PZM11LL Can be modified to operate with Phantom Power by moving R14 to R13.
(R14 is a zero Ω resistor).
This can also be done by removing R14 and placing a Jumper across R13.
Gain Adjustment
By default R5 is 1KΩ resistor. The gain can be adjusted by swapping this resistor.
The mic comes with preloaded surface-mount resistors.
-1K minimum headroom
-2K 6 dB more headroom
-3.9K 12 dB more headroom
-8.2K 18 dB more headroom
-100K maximum headroom (mic level)
