Suitable for retail outlets, banks, university campuses and other large-scale PA / BGM applications, the system connects via standard TCP/IP to a LAN or WAN, and is simple to operate and offers compatibility with a wide range of audio sources.
"Being IP-enabled, the new AOE212N brings PA systems right up to date," comments Chris Edwards, marketing director of CIE-Group. "The AOE212N device can distribute content locally and globally, whatever the requirement. It is extremely versatile and can be used as a full-on Audio-over-IP public address system or just a background music system, and is quick to set-up, monitor and control using a simple browser-based user interface."
The AOE212N offers bi-directional functionality which means it can operate as either a transmitter or receiver. It creates a distributed audio system by connecting up to eight audio sources (eg CD player, MP3 player, paging microphone or audio media streamer) to an AOE212N configured as the 'Transmitter'. This unit is then connected to a standard network via Cat 5e/6/6e cabling, transmitting both high quality audio and data (for device switching and RS-232) to up to 60 'remote' amplifier zones/sites over LAN or 20 over WAN. At each remote zone an AOE212N is configured as the receiver and is connected to a standard 100v line or low impedance amplifier.
When used in conjunction with the Inter-M PMU Series amplifiers, the AOE212N is only required as a transmitter device. The PMU amplifiers feature on-board AoIP connectivity and act as both amplifier and audio over Ethernet receiver. Furthermore power is via either AC or DC power allowing for uninterrupted signal broadcast using battery back-up, as well as supporting portable or temporary audio systems in applications such as outdoor events.
The AO212N also provides simultaneous data-over-ethernet to each channel, allowing for contact-closure device remote control or RS-232 control integration.
