Easy Selection Considerations:

  • Determine Ceiling Heights & Type
  • Noise Levels
  • Style, Decor & Color


Speakers are generally used for interior environments and provide high quality music and voice reproduction. Speakers are designed to sound good and look good.  It¹s easy to use hundreds of One-Way speakers in a zone - large numbers of speakers simply require additional power (VPU’s) per area - see Step 3.


All One-Way speakers/horns will have an audio pair (line level) connection and a power pair (-24VDC) connection. Speakers can be networked together using standard telephone/datacom low voltage wiring (CAT 5/6).
The talkback feature is most suited in areas where people can have a normal conversation. Talkback is not recommended in noisy environments. Most talkback zones can have 2 Talkback speakers plus 40 One-Way speakers. All talkback speakers/horns will have only one audio pair connection and must be used with a Talkback page control unit.
