For applications that incorporate 25/70v or 8 ohm speaker systems modular IP7- SS8/SS20 Audio Amplifiers are a perfect solution. The IP7 series can drive 8-Ohm speakers, or multiple speakers in an array. . With a maximum output of 20 watts the SS20 (8 Ohms) is capable of driving paging horns with sound pressure levels in excess of 120 db SPL. For low output applications (<8 watts) the SS8 and SE8 can use Power of Ethernet (POE).  

For specific applications that require unique coverage inside a building solutions Digital Acoustics offers the SPKR-11-VC-P Bi-directional Speaker. The design incorporates a completely self contained VoIP IP Amplifier and dual speaker paging system. The surface mounted enclosure projects sound side-to-side for maximum efficiency and coverage length. It only requires an Ethernet connection with PoE, no other wiring is required. It is intended for indoor wall or ceiling mount for corridor paging of voice, tones and music.
Bi-Directional VoIP Speaker 11-BD

  • One Bi-directional speaker can replace up to 10 ceiling mount speakers

  • Reduces installation labor up to 80%

  • Ideal for hallways with hard surface ceilings to limit buried conduit runs

  • High intelligibility dual 4 inch speaker system

  • Built in IP Amplifier simplifies wiring to just 1 Poe Ethernet connection per device

Audio Distribution  Systems, PA, Paging ... the IP advantage

PA/IP (PA over IP), SIP enabled VoIP paging provides unique advantages over analog paging systems

  • Proven cost saving over new single function wiring in deployment into existing buildings.
  • Spans multiple facilities inter-city, regionally and globally, without head-end hardware.
  • Scalable network topology facilitates expansion possibilities
  • Incorporates system wide capability to add intercom, 2 way-audio monitoring (reentrant capability) and remote monitoring functions.
  • Perfect for Retailers, Government  and School systems with complex inter-building distribution need. Multicast Protocol enables seamless, clear, low bandwidth audio distribution
  • Easily integrate into emergency systems.
  • Provides Ethernet network based redundancy for emergency broadcasts, and employee evacuation systems.
  • Design to integrate to SIP and VoIP enabled systems via TalkMaster(tm) software.

Emergency Preparedness / IP, VoIP and SIP Paging Systems

  • Provides supplemental reach to overhead IP paging, parking, inter-building and even individual desktop notification. Connectivity via SIP eases addressing in VoIP systems
  • Network based system provides integration path to meet needs and requirements for notifications to individuals with disabilities.
