2 English www.pioneerelectronics.com IMPORTANT NOTICE: The serial number for the equipment is located on the rear of the product. Please write this serial number on the warranty sheet and keep it in a secure area for future reference. BEFORE USE • Thank you for buying this Pioneer® Elite® product. • To assure maximum performance from your new speakers, please read through this operating guide before you install or use them. After you have finished reading this operating guide, store it in a safe place for future reference. • The nominal impedance of this speaker system is 4 ohms. It must be connected only to an amplifier or receiver designed to drive 4-ohm loads. Connect the speaker system to an amplifier with a load impedance rating ranging from 4 to 16 ohms (a model with "4-16Ω" displayed on the speaker output terminals). • In order to prevent damage to the speaker resulting from input overload, please observe the following precautions: - Do not supply power to the speakers in excess of the maximum rated power. - When connecting or disconnecting cables, be sure amplifier power is OFF. - Do not use excessive amplifier volume if using a graphic equalizer to emphasize high or low frequencies. CONNECTING YOUR SPEAKERS IMPORTANT: Make sure all equipment is turned OFF before making any connections. Correct wiring of your speakers is essential for achieving the best sound quality. Be careful to ensure proper polarity ( +/- ) of connection. We recommend a minimum of 18 gauge for runs up to 25 feet, and thicker for longer runs. Most speakers cable is coded to ease this task. Typically the ribbed or striped side, or the side with the connector marked in red or white, is connected to the positive (red) terminal. Make sure that the amplifier positive (red) terminal is connected to the loudspeaker positive (red) terminal, and that the amplifier negative (black) terminal is connected to the loudspeaker negative (black) terminal. If the wires you're using are not already terminated with banana plugs, spade lugs, etc., strip off ½" of insulation from the ends of the cable, twist the bare strands and insert into the binding posts. Take care that no stray strands of wire short across between the terminals. Connect the cable from the front left or right channel, or the rear left or right surround channel, to the bottom set of binding posts on the speaker. If you are using the height channel drivers in the SP-EFS73 floorstanding speaker or SP-EBS73-LR bookshelf speaker for Dolby Atmos® or another surround sound technology with height channels, connect the cables for the corresponding height channel (left front height channel of the receiver or amp to the left front speaker's height channel input, right rear height channel of the receiver or amp to the right rear speaker, etc.) as seen to the right. INSTALLING AND REMOVING THE GRILLES With both the SP-EFS73 floorstanding speaker and the SP-EBS73-LR bookshelf speaker, the grilles covering the front drivers and the height drivers may be removed if desired, as seen below. To remove either or both grilles, pull gently on the grille near one of its mounting points. You don't need to pull the grille all the way out of its grommet at first. Work your way around the grille, gently working it loose around each mounting point. Once the grille is completely loosened, you can remove it. To reattach it, align the pegs on the grille with the holes in the speaker and press in slowly around the mounting points until the grill is pushed in all the way.
