original QM-WMIC Operations & Installation Guide (Doc. 6245). Specifically, this
addendum adds and corrects specifications for the Microphone Input Levels listed on
page 3.

Correction for Microphone Input Level Specifications

The specification table on page 3 is missing dBu specifications for the XLR Input
