[. . . ] If air frieght is requested by the dealer, the difference between air and surface charges will be billed to the dealer. This limited warranty does not cover products that have been abused, altered, modified, or operated in other than specified conditions. Prior factory approval is required on all returns. Returned equipment or defective parts must be shipped freight prepaid to us by the dealer or customer. [. . . ] Total depth including the handles is 16-3/8" inches. Front panels are machined from solid aluminum stock, with a black powdercoat finish and sturdy rack mount handles. Placement of the amplifier is not critical for normal operation, provided sufficient airflow is allowed to reach the heatsink array. If the unit is to be placed on a shelf, or a similar unenclosed area, allow four inches of clearance behind the fan air intake to permit airflow through the array. If the amplifier is to be mounted in an equipment rack or cabinet with heat producing equipment, be sure that environmental operating temperatures do not exceed 55 degrees C (131F). Should overheating occur because of inadequate ventilation, the temperature protection circuitry will automatically protect the amplifier. When a safe operating temperature is restored, the amplifier will return to normal operation. INSTALLATION & OPERATION when the temperature drops below 95 C. Because the amplifiers are capable of delivering high power from a relatively small physical package, considerable heat can develop in cabinets containing several components. A good rule of thumb to adopt is to provide forced air cooling in any enclosure containing four or more electronic components. Fan Assist Cooling The SMART TA6300 is equipped with a convection cooling system utilizing massive heatsink extrusions and two fans. Soft Clip Speaker Protection SECTION 3 Features Power Connections The SMART TA6300 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 Certain conditions of operation (restricted airflow cooling, sustained high power operation into low impedance loads) can result in a rise in output device case temperature sufficient to affect the amplifier's performance. Should the heatsink reach 95 C, the output will automatically be disconnected from the load (loudspeaker) and will remain disconnected until the temperature drops below 95 C. The action of removing the load has the effect of eliminating output current. This, in turn, results in an immediate and rapid drop in temperature. The load will automatically be reconnected The SMART TA6300 incorporates Soft Clip Speaker circuitry. This circuitry prevents the amplifier from being driven into a hard clip state, which prevents speaker damage caused by the amplifier being over driven or into DC state. Selectable Input Sensitivity The SMART TA6300 is equipped with selectable input sensitivity. [. . . ] CAUTION: The TA6300 amplifier is a product of the most advanced technology and manufacturing techniques and is fully protected against overheating, input overload and shorted or mismatched loads. As is the case with any precision instrument, some care should be taken in the unit's operation. The following precautions should be noted and adhered to. Damage resulting from their omission is not covered under the terms of the warranty. [. . . ]
