Annuncicom PS1

Desktop/Wallmount IP Intercom and paging master station, headphone and gooseneck mic support.

The Barix Annuncicom PS1 is a universal IP Audio device, both compact and elegant, and gives broadcasters, commercial businesses, office buildings, educational institutions, medical facilities and others a simple, fully integrated hardware solution for paging and intercom over IP.

The Annuncicom PS1 features two backlit push-to-talk buttons, volume control and a built-in speaker and microphone, giving security guards, receptionists and other operators a simple way to make announcements to an entire facility. Two mini-jack connectors support the use of a headset, or a goose-neck microphone and headphones. The device connects to standard IP network, allowing systems integrators and end users to take advantage of existing infrastructure, reducing costs and equipment. Power over Ethernet (PoE) capability further simplifies installation, requiring only a single cable to the device.

The compact design of the Annuncicom PS1 accommodates wall-mount and desktop installations. Using the optional belt clip and a headset, the Annuncicom PS1 is the ideal choice for an IP based party-line intercom.

The Annuncicom PS1 can also integrate with background music systems — ideal for retailers, restaurants, hotels, clubs and other entertainment venues that wish to override a stream with announcements.

Bi-directional capability enables intercom for facility-wide, two-way communications — taking the PS1 beyond a basic paging device for ski areas, university campuses and other large areas that require talkback capability.

The supported codecs (PCM/G.711/G.722/MP3) and range of sample rates (8..48kHz) allow the optimization of the audio quality for the application. Up to CD/HiFi (mono only!) quality can be achieved.
