ENGLISH Basic connections NOTE • Do not plug in the power cord until all connections have been completed. • When making connections, also refer to the operating instructions of the other components. • Be sure to connect the left and right channels properly (left with left, right with right). • Do not bundle power cords with connection cables. Doing so can result in humming or noise. • Do not turn up the volume without a turntable connected to the PHONO input terminals. Doing so will cause humming or noise.

Audio cables Analog connections (stereo) (White) L L (Red) R R Speaker connections Stereo pin-plug cable Speaker cables Connecting the audio equipment Cautions on playing SA(Super Audio) sources: When regular speakers not compatible with SA sources (DVD Audio discs, Super Audio CDs and other sources, including treble components above the audible range), set the properties of the player (DVD Audio player, Super Audio CD player, etc.) for use with regular speakers (or amplifiers). The speakers may be damaged if the volume is set too high when playing SA sources. For instructions on player settings, refer to the operating instructions included with the player. Connecting the speakers Connecting the speakers cables Carefully check the left (L) and right (R) channels and + (red) and - (black) polarities on the speakers being connected to the unit, and be sure to connect the channels and polarities correctly. 1 Peel off about 0.03 ft/10 mm of sheathing from the tip of the speaker cable, then either twist the core wire tightly or apply solder to it. 2 Turn the speaker terminal counterclockwise to loosen it. 3 Insert the speaker cable's core wire to all the way into the speaker terminal. 4 Turn the speaker terminal clockwise to tighten it. NOTE • Connect the speaker cables so they do not stick out of the speaker terminals. The protection circuit may be activated if the wires touch the rear panel or if the + and - sides touch each other (vpage 6 "Protection circuit"). • Never touch the speaker terminals while the power supply is connected. Doing so could result in electric shock. nnProtection circuit The protection circuit is be activated in the following situations: • If the speaker cable wire touches the rear panel or screws or if the speaker cable wire touches the speaker cable's + and - sides are touching • If the surrounding temperature is extremely high • If the inside of the amplifier gets hot to extended use at a high output If the protection circuit is activated, the speaker output is blocked and the STANDBY indicator flashes in red. If this happens, unplug the power cord, then check the connections of the speaker cables and input cables. If the unit becomes very hot, wait for it to cool off and improve the ventilation around it. After doing this, plug the power cord back in. If the protection circuit is activated even though there are no problems with the ventilation around the unit or in connections, the unit may be damaged. Turn off the power and then contact a marantz service center. 6
