OPERATION AND SERVICE INSTRUCTIONS

The Shure Model SR112W Speaker System is a woodgrain version of the Shure Model SR112. Most of the information about the SR112 in the accompanying data sheet (MODEL SR112 AND SR116 SPEAKER SYSTEMS) also applies to the SR112W. The differences are as follows.

DESCRIPTION

The SR112W is designed for permanent indoor installation only. It is constructed of 12.5 mm (1/2 in.) particleboard and covered in woodgrain, scuff-resist- ant vinyl. The grille is of rugged, brown acrylic fabric, with pull tabs for easy access to the speakers. For wall mounting, the SR112W can be used with the optional Shure Model A112D Wall Mount Swivel Bracket.
