Wideband IP Speaker<\/h3>\n

The 8188 SIP Ceiling Speaker supports the Wideband G.722 HD voice codec. Consequently, there is high intelligibility and clarity of audio from the speaker for IP paging of voice announcements and emergency notification. The result is better STI-PA scores, which is important in meeting standards such as NFPA 72 and NEMA SB-40 for Emergency Communication in Education. For example, the 8188 IP speaker was measured to have a STI-PA intelligibility score of 0.95 in an office environment at 70 dBA level with ambient noise of 49 dBA.<\/p>\n

Clear, Crisp, Rich Audio – for Voice and Background Music<\/h3>\n

The 8188 is a music capable speaker supporting the Super-Wideband frequency response. Using the music input of the\u00a08301 IP Paging Adapter<\/a>, music can be streamed to the 8188 speaker as multicast. The music stream can be configured at a lower priority to allow voice paging, emergency alerts and scheduled tones \/ announcements to interrupt background music.<\/p>\n

Scale Algo IP Paging Speakers with Multicast<\/h3>\n

The 8188 SIP Ceiling Speaker supports multicast send or receive. As a result, many Algo IP speakers can be deployed to cover any size building, campus (e.g., classrooms in a school, college or university) or enterprise.\u00a0 There is no limit to the number of devices part of a multicast, and a minimum of network traffic activity is utilized.<\/p>\n

\"Algo<\/p>\n

A single registered 8188 can be configured to multicast to any number and mix of Algo IP speakers, strobe lights, paging adapters and multicast supported IP telephones.<\/p>\n

Multicast provides cost-effective scalability using a minimum of SIP registered endpoints, as only the endpoint designated to send the multicast needs to be registered. Devices configured to receive the multicast do not need registration.<\/p>\n

Support is available for RTP multicast, in addition to Polycom Group Page, Singlewire InformaCast (part no.\u00a08188-IC) and Syn-Apps Revolution.<\/p>\n

Any combination and number of Algo IP endpoints can be configured as a multicast for emergency alerting to cover any size room, building, campus or enterprise.<\/p>\n

Using Multicast for Zone Paging<\/h3>\n

Multicast zone paging for up to 50 zones can be configured from a single 8188 IP speaker. Zones can be selected one of two ways. One option is to map multicast page zones to individual SIP extensions on the speaker. Fifty (50) page extensions are available for this purpose. Alternatively, in order to minimize SIP registrations, multicast page zones can be configured in the SIP Audio Alerter as a DTMF key press selection using the dial pad of telephone making the page call.<\/p>\n

Note: Additional page zones can be configured by registering individual Algo IP speakers for specific room paging (e.g. school classroom). Speakers with SIP registrations can also be configured to be a member \/ receiver of multicast zones.<\/p>\n

Dynamic Volume Control & Talkback<\/h3>\n

Speaker volume can be configured via the web GUI of the endpoint. However, the 8188 speaker\u2019s microphone can also be used to monitor and adapt speaker volume according to background noise levels. This unique Algo feature is called Ambient Noise Compensation. Where many speakers are deployed in a room \/ hallway \/ common area, volume can self-adjust to the background noise levels at each speaker location. Ambient Noise Compensation helps to ensure that announcements and alerts are heard but never too loud. Talkback is supported in the 8188. This feature can be enabled for a page call using the speaker\u2019s microphone.<\/p>\n

Multi-Application SIP Extensions<\/h3>\n

Multiple SIP registrations are available in this IP speaker, including Page (50), Emergency Alert (10) and Ring (10) extensions. On Page, the speaker will auto-answer when called for making public address (PA) voice announcements. For Ring and Emergency Alert extensions the speaker will play a configurable WAV file from 1GB device memory when the extension is called (e.g., ring tones for telephone alerting, notification alerts for safety \/ security \/ emergency events and informational announcements).<\/p>\n

Emergency Notification Alerting<\/h3>\n

For notification alerting of safety, security and emergency events there are two activation options available:<\/p>\n
