AUDIO CONNECTIONS
POPS15a includes two male XLR connectors. This configuration differs from the
standard male input and female out/thru due the to water and moisture
requirements of the product. Both the input and output/thru XLR connectors on
the POPS15a are made by Neutrik and require use of Neutrik connectors
NC3FXX-HD-D. The supplied XLR to XLR audio cable has two of the NC3FXX-
HD-D connectors.
The image below illustrates the top portion of the POPS15a input plate. Both the
audio input and audio thru connectors are shown. In this image both connectors
are shown with their water covers in place.
POPS15a also includes a “signal present” indicator and is positioned immediately
below the Pilot light. This indicator will illuminate when an audio signal is present
at the input to the system. The threshold is approximately -25dBV.
