ENA Amplifier - Monitoring

The ENA Amplifier provides extensive monitoring capabilities.

What can be supervised?

Internal supervision of:

• Temperatures
• Internal voltages
• Amplifier shutdown
• Fan
• Software

External connections:

• Supply voltages (AC and/or DC)
• Ethernet port(s)
• Speaker Line (SLM) faults
• LET (Line End Transponder) faults
• Remote Control Input (RCI) faults
• Remote Control Output (RCO) faults
• Headphone disconnected
• Microphone fault

In the Monitoring and Lines tab, you can configure Speaker Line Monitoring, LET Monitoring, RCI and RCO monitoring and Line-In monitoring. This will report faults whenever there is something wrong with the amplifier or connected speaker lines.

Channel 1 is the main directory number for the amplifier. All monitoring is reported as an event at this directory number, with separate sub-events for each channel. All station faults that are configured to be reported will automatically show up in the System log of the AlphaCom server, and trigger Event 43 Station Fault Report, and the sub-event indicating what type of fault.

After configuring speaker line monitoring, the channel needs to be calibrated. This should not be done when there is a call active or audio on the speaker line. The option Suspend Monitoring will turn off monitoring when there is audio on the channel output.

Error reporting

• Fault Relay: The Fault Relay on the back of the amplifier will trigger whenever there is an error. The relay will remain triggered as long as one or more errors are present.
• Amplifier GUI display: The Amplifier GUI display will indicate with a red exclamation mark if there are any errors. Use the Menu Selecetion Knob in front of the amplifier to navigate to Service > Local Message List to view current error messages
• Amplifier web interface: In the Faults section in the Monitoring and Lines > Status menu there is a live update of current active faults. The page is automatically refreshed every 10 seconds.
• AlphaCom System Log: Amplifier errors are reported to the AlphaCom, which will forward the error reports to the System Log.
• AlphaCom Event Handler: Amplifier errors are reported to the Event Handler of the AlphaCom, event 43 - Station Fault Report. It is possible to use the "subevent" to filter by different fault types.
• SNMP Traps - from Amplifier: The amplifier can be configured to report errors as SNMP Traps, see SNMP Settings
