System Designs

The core hardware component to Digital Acoustics' paging solution is the modular IP7- SS8/SS20 Audio Amplifier. The IP7 series can drive 8-Ohm speakers, or multiple speakers in an array. With the addition of a universal 25/70V transformer, a series of speakers can be powered by a single IP7 with the quantity of speakers determined by required output levels. 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).  

Every acoustic environment is unique and using the right speakers is important in providing intelligible public address solutions. Digital Acoustics' speaker offerings include:

• 8" Ceiling Mounts - Round and Square
• Surface Mounted Enclosures - Square and Sloped
• Internal Horns
• External Paging Horns
• Corrections Grade Solutions (Vandal Proof)
• Weather Proof & Flame-retardant
  

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

PA/IP (PA over IP) 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 (reentrant capability) and remote monitoring functions.
• Perfect for Retailers, Government  and School systems with complex inter-building distribution need.
• Easily integrate into emergency systems.
• Provides network based redundancy for emergency broadcasts, and employee evacuation systems.

Emergency Preparedness

• Provides supplemental reach to overhead paging, parking, inter-building and even individual desktop notification. 
• Network based system provides integration path to meet needs and requirements for notifications to individuals with disabilities.
• Cost effective means for compliance to Federal Emergency Decision and Notification Protocol OPM/GSA/NIH and other interagency requirements.

The flexible IP7 series product family supports paging over 25/70v line amps, desktop paging microphones and handsets. Hardware endpoint supports powering over PoE and daisy-chaining connections via dual-port RJ45  dual-port (SE8 only) and support for  horns, weatherproof enclosures , ceiling panels, wall panels, desktop and vandal proof speakers
