ENA2200-AC2 Amplifier
From Zenitel Wiki
The ENA2200-AC2 Amplifier is a class D amplifier providing 2 x 200W that can register to the ICX-AlphaCom server or a SIP server over an IP network. It 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, each with a maximum 200W output. The two channels can alternatively be combined into one channel ("One Channel Mode") where the two loudspeaker channels play identical audio in phase. Furthermore, the two amplifier channels can be bridged to provide a single 400W load.
The amplifier monitors the speaker lines for shorts, overload and opens. 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 amplifier and are reported via SNMP. In case of ICX-AlphaCom server, an error will raise an event in the Event Handler, which can generate reports to e.g. syslog, SNMP and internal log.
Configurable control inputs/outputs and audio inputs can be utilized locally or controlled by the system, such as using audio input for background music. The audio line input can also be configured in a Hardware Bypass mode, forwarding audio to the 100V channels even without a server available, adding redundancy and flexibility to the amplifier's functionality.
