The '''ENA2400-AC Amplifier''' is a 2 x 400 watt IP based amplifier that can register to the AlphaCom server over an IP network.

The ENA2400-AC amplifier operates from a 115/230 VAC supply and is designed to survive minor interruptions to the power supply.

The amplifier has two separate loudspeaker channels. Each channel can be addressed separately, i.e. belong to two different zones, or the two channels can be combined into one channel.

The amplifier monitors the speaker lines for shorts, overload and opens. A [[ELTSI-1|Line End Transponder (ELTSI)]] can be used for reliable detection of an open line. More than one ELTSI can be connected to the same line, allowing monitoring of several branches on the speaker line. The amplifier also monitors control inputs, power, temperature, network connections and every other component required for operation of essential services. Faults will be indicated locally on the [[ENA User Interface|amplifier display]] and fault relay, as well as reported to the AlphaCom server which can raise an event or forward the reports to syslog, SNMP and internal log.

The amplifier’s control inputs/outputs and audio inputs can be used locally by the amplifier (e.g. for PTT and audio from a handheld microphone) or can be controlled by the system (e.g. audio input for background music).
