Atlas Sound SM82-W Architect And Engineer Specifications, AtlasSound.com, SM82 Frequency Response

Care should be taken to ensure that the chosen fixing point is strong enough to support the SM82. Care should also be taken to ensure that the SM82 is not exposed to direct precipitation. A 5⁄8"-27 threaded hole is provided on the C-bracket to allow the SM82 series speaker to be mounted on any Atlas Sound microphone stand for near-field live sound applications. Four brass inserts are also provided on the bottom of the SM82 to accommodate OMNIMOUNT™ 75 series brackets. All inserts for mounting knobs are standard 1⁄4"-20 to allow easy substitution of off-the-shelf vandal proof torx head or "one-way" hardware. Input connectors include a sealed 1⁄4" phone jack and touch-proof 5-way binding posts capable of accepting up to #12AWG cable. 1⁄4" jack and binding posts are paralleled to allow "daisy chain" connections between the two connector types.

A tongue-in-groove cover with rubber wire exit grommet is provided to insure input connections are protected. Systems are available in black or white and can be painted to accommodate any architectural considerations.
