PREPARATION ■ IMPEDANCE SELECTOR switch CAUTION Do not change the IMPEDANCE SELECTOR switch while the power of this unit is turned on, as doing so may damage the unit. If the unit fails to turn on, the IMPEDANCE SELECTOR switch may not be fully slid to either position. If this is the case, remove the power cable and slide the switch all the way to either position. Select the switch position (LOW or HIGH) according to the impedance of the speakers in your system. Switch position HIGH LOW Impedance level • If you use one set (A or B), the impedance of each speaker must be 6 Ω or higher (R-S700) or 8 Ω or higher (R-S500). • If you make bi-wire connections, the impedance of each speaker must be 6 Ω or higher (R-S700) or 8 Ω or higher (R-S500). See page 13 for Bi-wire connection. • If you use one set (A or B), the impedance of each speaker must be 4 Ω or higher. • If you use two sets (A and B) simultaneously, the impedance of each speaker must be 8 Ω or higher. • If you make bi-wire connections, the impedance of each speaker must be 4 Ω or higher. See page 13 for Bi-wire connection. ■ Connecting speaker cables Remove approximately 10 mm (3/8 in) of insulation from the end of each speaker cable. Note When inserting speaker cables into the speaker terminals, insert only the bare speaker wire. If insulated cable is inserted, the connection may be poor and sound may not be heard. ■ Connecting via banana plug Tighten the knob and then insert the banana plug into the end of the corresponding terminal. CONNECTIONS ■ Bi-wire connection Bi-wire connection separates the woofer from the combined midrange and tweeter section. A bi-wire compatible speaker has four binding post terminals. These two sets of terminals allow the speaker to be split into two independent sections. With these connections, the mid and high frequency drivers are connected to one set of terminals and the low frequency driver to another set of terminals. This unit Speaker Connect the other speaker to the other set of terminals in the same way. CAUTION When making bi-wire connections, set the IMPEDANCE SELECTOR switch to HIGH or LOW depending on the impedance of your speakers: 6 Ω or higher: HIGH (R-S700) 8 Ω or higher: HIGH (R-S500) 4 Ω or higher: LOW See page 13 for more information about the IMPEDANCE SELECTOR switch. Note When making bi-wire connections, remove the shorting bridges or cables on the speaker. y To use the bi-wire connections, press SPEAKERS A and SPEAKERS B on the front panel or on the remote control so that both SP A and B light up on the front panel display.
