Chapter 2: Getting Started Connecting speaker cables Speaker cables consist of two insulated wires running together. Speaker connections are polarized and use positive (+) and negative (-) terminals that are colorcoded red and black, respectively. To help you connect the wires correctly, the positive wire is usually marked with a stripe or some other identifier. All you need to do is to connect the marked wire to the positive (+) terminals on the DRX-730 and speakers, and connect the unmarked wire to the negative (-) terminals. If you get them crossed over, your speakers will be out of phase and the sound will be unnatural and lack bass, so take care. 1 Strip about 10 mm (3/8 in.) of insulation from the end of each wire, and twist the exposed strands together to prevent possible short circuits. 10 mm (3/8 in.) Connecting a powered subwoofer You can connect a powered subwoofer (sold separately) to the DRX-730's SUBWOOFER OUT jack for a really deep bass sound. Using an audio pin cable (sold separately), connect the DRX-730's SUBWOOFER OUT jack to the powered subwoofer's input jack.
