PREPARATION Connecting speakers Be sure to connect the left channel (L), right channel (R), "+" (red) and "-" (black) properly. If the connections are faulty, no sound will be heard from the speakers, and if the polarity of the speaker connections is incorrect, the sound will be unnatural and lack bass. CAUTION • Use speakers with the specified impedance shown on the rear panel of this unit. • Before connecting the speakers, make sure that this unit is turned off. • Do not let the bare speaker wires touch each other or do not let them touch any metal part of this unit. This could damage this unit and/or speakers. • Use magnetically shielded speakers. If this type of speakers still creates the interference with the monitor, place the speakers away from the monitor. (U.S.A. and Canada models only) If you are to use 6 ohm speakers, be sure to set the IMPEDANCE SELECTOR switch on the rear panel to the upper position using a straight slot screwdriver. Switch position Upper Lower Speaker FRONT A or B CENTER SURROUND FRONT A or B CENTER SURROUND Impedance level The impedance of each speaker must be 6 Ω or higher. The impedance of each speaker must be 8 Ω or higher. ■ Before connecting to the SPEAKERS terminal A speaker cord is actually a pair of insulated cables running side by side. Cables are colored or shaped differently, perhaps with a stripe, groove or ridges. Connect the striped (grooved, etc.) cable to the "+" (red) terminals of this unit and your speaker. Connect the plain cable to the "-" (black) terminals. Remove approximately 10 mm (3/8") of insulation from the end of each speaker cable and then twist the bare wires of the cable together to prevent short circuits. 10 mm (3/8") CONNECTIONS ■ Connecting to the FRONT A SPEAKERS terminals 2 1 3 Red: positive (+) Black: negative (-) 1 Loosen the knob. 2 Insert the bare end of the speaker wire into the hole on the terminal. 3 Tighten the knob to secure the wire. Connecting the banana plug (except U.K., Europe, Korea and Asia models) The banana plug is a single-pole electrical connector widely used to terminate speaker cables. First, tighten the knob and then insert the banana plug connector into the end of the corresponding terminal.
