audio pass-through circuit. This circuit controls analog audio input/output pass-through
on the screw terminal connector on the back of the EAS device. Pass-through audio
allows external balanced audio to be passed through the EAS device and interrupted
during an EAS audio activation.
• If the Main audio output is to be tested by playing a file or a tone, or if pass-
through audio is not needed, the Main Analog Audio Passthrough check box should
be disabled. This will enable full time output of internal audio.
• Otherwise, check to enable analog audio pass-through. When Pass-through is
Enabled, the only time EAS device generated audio is played on the Main audio
output port is during an EAS alert.
Tests:
• To test the Main and/or Auxiliary Audio outputs, attach speakers to the EAS device
audio output ports.
• Run the various tone test buttons.
Tests allow the EAS device to play each of the two single tones that comprise the dual-
tone EAS Attention Signal.
Alert Forwarding and Alert Origination
The Main and Auxiliary Audio tables display an active hyperlink showing whether the
forwarded and originated alert audio is output on the audio device.
To make changes to these states:
• Click the hyperlink to jump to the correct Decoder Audio or Encoder Audio setup
page.
• Modify the associated checkboxes.
Direct Audio Output Levels & Tests (Upload Audio .WAV Section)
Upload Audio .WAV file
The interface at the bottom of this screen allows .WAV and MP3 files to be uploaded
into the EAS device.

WAV files.
Uploaded audio files are available for tests as well as for encoding and manual
forwarding.
Radio Tuners

configured, tuned, and monitored using the
Setup > Audio >Radio Tuners
screen.
Each radio is tuned/configured via the web interface to any AM, FM, or NOAA
frequency.
Note
The EAS Attention signal
and WAV files can be
played as described
above for the front
panel speaker interface
table.
Note
External antennas are
usually required for
proper radio reception.
Antennas are connected
to a coax connector
on the back of the EAS
device. Antennas can
be purchased through
third party vendors.
