DESCRIPTION The Shure Model SR112B and SR116B Speaker Systems are compact, rugged, heavy-duty, two-way units. They are designed for use with Shure Model SR105 or similar high-power amplifiers in studio monitor, night club or other applications requiring a small, wide range speaker system. When properly installed and connected, the SR112B and SR116B will provide outstanding performance in critical applications due to their wide frequency response, low distortion, and smooth dispersion characteristics. The Speakers have a nominal impedance of 8 ohms and are designed to operate with amplifiers capable of delivering up to 100 watts to an 8-ohm load. They can be used either direct-coupled or with a constant-voltage 25-volt line, or 70-volt line using a Shure A1 02A Transformer. Quality sound reproduction is achieved through the use of two 8-inch heavy-duty speakers and a high-frequency driver coupled to a 120" radial horn. The front-ported bass reflex design of the enclosure provides low-frequency enhancement. A built-in series-type passive crossover network provides 6 dB per octave rolloff for the lowfrequency speakers and 18 dB per octave rolloff for the high-frequency driver. A four-position attenuator switch allows high-frequency level adjustments of -4, -2, 0 and +2 dB. The SR112B (see Figure 1) is a weather-resistant unit, and is designed for permanent installation either indoors or in a protected outdoor environment such as under the roof of an open pavilion. Adhesives used in the SR112B are moisture-resistant, and trim and fastening hardware have a high corrosion resistance. The SR116B is a portable unit (see Figure 2), and is designed for temporary installation either indoors or in a MODEL SR116B SPEAKER SYSTEM FIGURE 2 protected outdoor environment. The SR116B is supplied with a 15m (50 ft), 18-gauge, rubber-jacketed connecting cable with locking phone plugs, and a black vinyl grille cover. The corners of the SR116B are equipped with steel protectors. A retractile handle and balanced design contribute to ease of transporting. Both units are constructed of 15.9 mm (5h in.) wood, and covered in black, scuff-resistant, textured vinyl. The attractive black sculptured fabric grille is rugged, cleanable, and replaceable if damaged. The radial horn and baffle board assembly is ruggedly constructed of shockresistant thermoplastic resin. Molded feet protect surfaces and permit stacking. The SR112B and SR116B may be operated vertically on their own feet, or in a tilted position using an appropriate support. The Shure A112A Tilt Bracket and the A112D Wall Mount Swivel Bracket provide for tilting on a horizontal surface or wall or ceiling mounting. A slip-on protective cover (Model A112C) is also available.
