[. . . ] Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. CAUTION: Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: Designed to fit into a standard 19-inch equipment rack, the unit takes up only two rack spaces. If amps are racked with spaces between them, solid non-vented rack panels are recommended between amps. provide standard rack-mount clearance of 2 inches on each side and 5 cm in the rear. This unit comes with a variable speed fan that auto-adjusts fan speed depending on the temperature of the unit during operation. Airflow is front to back, so do not place any object that may prevent heat from exiting the unit from its back vent. They are suited for applications such as churches, concert tours, stages, disco, pubs, or any place that requires amplifier installation. PARALLEL WIRING USING THE SPEAKON® CONNECTORS With this wiring, a signal sent to Channel 1 is paralleled to both channels so that it is reproduced by both speakers.
