The CyberData SIP-enabled VoIP V2 Loudspeaker Amplifier (AC-Powered) provides an easy
method for implementing an IP-based overhead paging system for both new and legacy
installations.
With up to 25 watts of driving power (802.3at), the Amplifier provides direct drive of a standard
Horn speaker and supports a line-out connector for connection to an external amplifier. The
interface is compatible with most SIP-based IP PBX servers that comply with the SIP RFC 3261. For
non-SIP environments, the Loudspeaker Amplifier can be configured to listen to multicast address
and port number combinations to form paging zones.
1.1 How to Identify This Product
To identify the VoIP V2 Loudspeaker Amplifier (AC-Powered), look for a model number label
similar to the one shown in
Figure 1-1. The model number on the label should be 011095.

RTFM Switch
To broadcast a Loudspeaker Amplifier’s current IP
address, press and hold the RTFM switch for a couple of
seconds and then release it.
To restore the factory defaults, complete the following
steps:
1. Press and hold the RTFM switch until you hear the
Loudspeaker Amplifier announce the words, “restoring
defaults” and “rebooting”.
2. Release the RTFM switch. The Loudspeaker Amplifier
will be restored to the factory default settings.
