Audio Setup - Monroe One-Net SE User Manual

AUDIO SETUP

Audio is at the heart of an EAS system. Because the EAS devices is configured ready for
average field situations, the Emergency Alert System requirements in your specific area
could require some special tuning:
• At a minimum, users will need to use the Setup > Audio screens to tune the Radio
stations used for EAS monitoring.
• You may need to adjust the decoder input levels for the selected stations, since
every station will vary in its signal strength.
• Audio output levels may need adjustment to fit with your broadcast parameters.
There are four tabbed sub-pages on the Setup > Audio page:
• Decoder Audio
• Encoder Audio
• Audio Output Levels/Tests
• Radio Tuners
Audio Output Levels/Tests: Direct Audio Output Levels and Tests
The Direct Audio Output Levels and Tests screen is used to configure:
• Audio output levels for device ports
• Audio Output sample rate and the audio preview devices group
Each audio output device results in an audio configuration interface on this page
-
- Audio WAV and MP3 files can be uploaded into the EAS device from this page
All standard EAS devices come from the factory with:
• Front Panel speaker
• Main audio output device
• One auxiliary audio output device.
A labeled configuration table is provided for each one of these output devices with:
• Controls for setting output levels from 0 to 100% and for running audio tests
• Indications of whether alert origination and forwarding will use the specific audio
output
• A main audio toggle control for enabling or disabling the analog audio pass-through
option
Testing and Calibrating Levels
Audio tones can be played through each available audio output to test audio connec-
tions and calibrate levels using audio test equipment:
• Configure the levels by entering numbers from 0 to 100 for any specific port.
• Output level values near 70 are a good starting point.
• Each audio device displays the same style of table for the control interface.
