[. . . ] makes no warranties, express or implied, including warranties of merchantability or fitness for a particular purpose. RETURN POLICY: Factory authorization MUST be obtained before returning any product. A 15% restocking charge will be issued on unused equipment (in original box) that is returned for credit. Credit is issued to the dealers account. [. . . ] All chassis components are precision machined from high quality aluminum and sheet steel stock. The entire package concept is directed toward maximum efficiency of space and structure, accounting for the unit's compact size and light weight. Installation All SMART amplifiers are designed for mounting in a standard 19 inch equipment rack, or one of the many rack type portable cases available on the market. The amplifiers require 3-1/2 inches of vertical panel space, with 13-1/2 inches required behind the panel. Total Certain conditions of operation (restricted airflow cooling, sustained high power operation into low impedance loads) can result in an increase in output device case temperature sufficient to affect any amplifiers performance. SMART power amplifiers are specified for operation from 120-240 Volt, 50-60 Hz mains supply. Equipment for domestic (USA) consumption includes a captive cord with a three pin polarized plug. In new installations and portable sound systems, or any situation in which the mains power is suspect, it is wise to confirm appropriate voltage and line polarity BEFORE connecting the instrument to power sources. Thermal Protection depth, Including handles, is 14-3/4 inches, Front panels are machined from solid aluminum stock with a black textured finish and sturdy rack mount handles. Placement of the amplifier is not critical for normal operating conditions, provided that sufficient air flow is allowed to reach the heat sink array. to be placed on a shelf, or a similar unenclosed area, allow four inches clearance behind the heat sink to permit vertical air flow through the array, For installation in a cabinet, allow an additional two inches above and one inch below the amplifier to permit air to be drawn around the back of the unit. NOTE: Channel Two's input becomes a signal output for use in Daisy Chaining additional amplifiers. 2) STEREO: This is the amplifiers standard mode of operation where channel inputs and outputs corresponds (Chan. 2 out. ) 3) BRIDGED: This mode is used to obtain the highest power output levels possible from the amplifier. Both Channels combine to form a single high power mono output. OUTPUT CONNECTIONS Output connections are made via five-way binding posts. Polarity is indicated by red and black terminals. We suggest the use of dual banana plugs for convenient and reliable hook-up. They also allow quick connection changes, when reversing polarity, as required during test and calibration of multilevel biamplified and triamplified systems. Heavy Class 11 wire may be used by unscrewing the large plastic portion of the output terminal and inserting the wire into the hole provided. EXTREMELY IMPORTANT: When making wire connections, Double Check that NO wire strands or ends touch an adjacent terminal, shorting the output. CAUTIONS: Never strap the two red output terminals together (in parallel). [. . . ] THERE ARE NO USER SERVICEABLE COMPONENTS INSIDE THE AMPLIFIER. AVOID POTENTIALLY DANGEROUS SHOCK HAZARDS. REMEMBER TO KEEP THE COVER CLOSED AT ALL TIMES. Set the INPUT SELECTOR SWITCH to BRIDGE. [. . . ]
