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)
