Alert Decoding Audio Configuration
Alert decoding occurs from active analysis of the audio input source on the
Main and Auxiliary audio devices. Each stereo input to an audio device allows
for two EAS decoder channels. Therefore the One-Net provides four
decoders. Under the
Alert Decoding Audio Configuration section, each
audio device available for the One-Net is shown with a table that displays:
Decoder Name Audio Input Level (1..100) Audio Level Status Decoder Enable
Under each of these columns is displayed information/controls per decoder.
The Decoder labels, shown for the Main Audio as LP1 and LP2, can be
changed by the user if desired. The interface allows the audio input level and
the decoder enable/disable to be changed per decoder. Changes become
effective immediately. The Audio Level Status is a very useful tool to test for
correct audio input levels. It will display if an audio signal is too low or high
or OK. It can also detect if an audio input is silent. The level status is updated
each time this page is redisplayed or when audio changes are submitted. Set
audio input levels until the Green OK level is achieved.
Snapshot
Clicking on any of the four “Snapshot” buttons will create an audio .wav file
for that specific decoder. This file contains the last three minutes of audio
detected by the decoder. You can click on the link below the decoder to play
the file. Snapshot is mainly used for troubleshooting purposes.
Placing a check mark in the “Decoded Alert Auto-Snapshot” box will create a
.wav file every time an alert is decoded. This feature is also used mainly for
troubleshooting purposes.
EAS Auto-scale
Placing a check mark in the “EAS Auto-scale” box will allow the One-Net to
automatically adjust the audio level to a decoder if the level is too high or too
low. This feature is used if signal levels from a source are not stable.
