TIA568 Wiring Standards

How to decide which wiring pattern to use:

1. Does the job specification call out a wiring pattern?
2. Does the customer/end user have a preference for T568A or T568B?
3. Have patch panels already been purchased for the job? If so, they will probably be either T568A or T568B. The jacks should be wired to the same pattern as the panels.
4. Are you adding on to an existing wiring plant? If so, your new wiring should match the existing wiring.

If none of the factors above apply, either T568A or T568B may be used. It is important to ensure that the workstation connectors and the patch panels are wired to the same pattern. T568B is commonly used in commercial installations, while T568A is prevalent in residential installations.

FASUB70 Add Amazing, Extended, Low Frequency Response To Any Distributed 70.7V System!

Atlas FAPSUB 8" Tuned & Ported 60W @ 70.7V/100V Ceiling Subwoofer System (2 Pack)


The FAPSUB adds impressive low frequency response to any full range distributed system

The FAPSUB consists of a highly efficient 8", 8 ohm subwoofer designed and built by Atlas Sound to work optimality in the FAPSUB enclosure system. A highly efficient, 3-pole filtering network eliminates unwanted high frequencies from the woofer, while the 937 cubic inch, tuned and ported, deep drawn steel enclosure provides bass response down to 45Hz (±10dB).

A special low saturation 70.7V/100V transformer is included with 1.9, 3.8, 7.5, 15, 30 and 60 watt primary taps (@70.7V) to match and balance the subwoofer with full range speakers without the need for separate amplification. A convenient front mounted selector switch allows tap selection without the need to remove the speaker from the ceiling. This tap selector switch also includes a transformer bypass setting for 8 ohm direct coupled applications.

Features

  • Low crossover point greatly reduces localization (ability of listener to identify the subwoofer location)
  • Detachable, Phoenix style, locking, four-pole connector provides for easy daisy chain wiring
  • Uniquely designed, "easy access" input panel design allows for "thru" conduit runs using flexible or rigid conduit
  • Front mounted tap selector switch for easy system tuning adjustments includes transformer bypass setting for 8 ohm direct coupled operation
  • High efficiency, passive crossover network eliminates the need for dedicated amplifier and/or active crossover
  • Attractive grille and bezel matches aesthetics of other Atlas Sound FAP Series
  • Easy installation in drop tile or sheetrock ceilings via C-ring/V-rail tile bridge and "dog leg" mounting system (included)
