[. . . ] To reduce the risk of dropping voltage to a minimum and to eliminate the danger of damaging the battery cables by thermal overload, these cables have to be at least 2. 5mm in diameter, each Switching the amplifier on or off is performed through the power switch (6). CONNECTING THE OUTPUT TERMINALS CAUTION TERMINALS marked with the symbol are HAZARDOUS LIVE and the external wiring connected to these TERMINALS requires installation by an INSTRUCTED PERSON or the use of ready-made lead or cords to avoid the risk of electrical shock, never touch the bare conductors leading to the output terminals of the amplifier when it is in operation. Under figures, show the possible connections of the " OUTPUT" speaker terminals accessible by removing the protective cover. Bear in mind the following rules: Constant impedance lines The total impedance of the speakers connected must correspond to that selected on the amplifier's output terminals. The sum of the power capacities of the speakers must be no lower than the amplifier's power capacity. [. . . ] For equipment life, you have to adjust the volume at a lower setting. Speakers and Electronics 6. "POWER" switch Using the POWER switch lets you turn the main power on or off. The setting of this control determines the output that is present at the loudspeaker OUTPUT. We recommend to generally adjust the MASTER and the input level controls at mediocre positions. extreme setting, where the MASTER is set to maximum output and the input controls nearly set to their minimum or vice versa are not recommendable. Clockwise this control enhances the high frequency reproduction, while turning it counter clockwise attenuates the treble frequencies. If the control is set to its center position, the overall frequency response is not being altered. Electro-Voice Speakers and Speaker Systems are guaranteed against malfunction due to defects in Materials or workmanship for a period of five (5) years from the date of original purchase. The Limited Warranty does not apply to burned voice coils or malfunctions such as cone and/or coil damage resulting from improperly designed enclosures. Electro-Voice active electronics associated with the speaker systems are guaranteed for three (3) years from the date of original purchase.

When the provided plug does not fit your outlet, consult an electrician for replacement of the obsolete outlet. Protect the power cord from being walked on or pinched particularly at plugs, convenient receptacles, and the point where they exit from thee apparatus. [. . . ] When in doubt, contact your dealer before you perform any connections. The terminal is meant for the connection of a small external loudspeaker that gets driven by an internal auxiliary power amplifier, providing a nominal output 1 watt. Only the mixed audio signal coming from "AUX1" , "AUX2" "CASSETTE" and "TUNER" are included in the output signal. In addition, the output signal is controlled only by the volume controls of the "AUX1", "AUX2", "TUNTER" and music signal level control(4). This function is toggle switch the "MONITOR OUTPUT"(4) additional loudspeaker. 1W / 8W Priority Aux. [. . . ]
