ENA Amplifier - Monitoring

The ENA Amplifier provides extensive monitoring capabilities.

What is supervised?

Internal supervision of:

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

External connections:

• Supply voltages (AC and/or DC)
• Ethernet port(s)
• Loudspeaker line faults
• LET (Line End Transponder) faults
• Remote Control Input (RCI) faults
• Remote Control Output (RCO) faults
• 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.
