While the A (Power) switch is in the up position, press the A AMP key on the remote control repeatedly to switch the power to the unit between on and standby mode. In addition, under either of the following conditions, the unit will enter standby mode.

• If the Auto Power Standby function is enabled. (➔ page 10)

• If you turn off the power to a device that has been set to trigger connection to this unit. (➔ page 20)

NOTICE

If you plan not to use the unit for an extended period of time, be sure to unplug the power plug from the AC outlet. Even when the power is turned off, a minimal amount of electric current is still flowing to the unit.

Note

• After you turn on the unit, it will take a few seconds before the unit can reproduce sound.

• Do not turn on the power to this unit again within 10 seconds after the power has been turned off. Doing so may generate noise.

• While the unit is in standby mode, to turn on power to the unit first set the A (Power) switch to the down position to turn the power off, then set the switch to the up position.

• While the unit is in standby mode, if you unplug the power cable from the AC outlet and then plug it in again, the power to the unit will be turned on.

Connecting speakers

Note

• Because this power amplifier is of the floating balanced type,

the following connections are not possible.

- Connecting between two “+” (or two “−”) terminals of the left and right channels (Fig. 1).

- Connecting each “−” terminal of the unit’s left and right channels to the opposite channel speakers (cross connection, Fig. 2).

- Connecting the left/right channel “−” terminals (or accidentally allowing them to come in contact) with the metal part of the rear panel of this unit.

–

• Do not connect an active subwoofer to the SPEAKERS L/R CH terminals. Connect the subwoofer to the unit’s PRE OUT jacks.

■ Using speaker cables

1 Remove approximately 10 mm of insulation

from the end of each speaker cable, and twist the exposed wires together tightly to prevent short circuits.

2 Unscrew the knob on each speaker

terminal, and then insert the bare wire into the side hole on the terminal.

3 Tighten the knob.

CAUTION

• Do not loosen the knob excessively. Otherwise, the knob may come off and a child may swallow it accidentally.

• To reduce the risk of electric shock, do not touch the speaker terminals while the power to the unit on.

NOTICE

• If the SPEAKERS terminals come into contact with a metallic rack, a short circuit may occur, resulting in damage to this unit. When installing the unit in a rack, maintain a sufficient clearance to prevent the SPEAKERS

terminals from coming into contact with the rack.

• Do not let the bare speaker wires touch each other, nor let them touch any metal part of this unit. Otherwise, the unit and/or the speakers may be damaged.

Note

All connections must be correct: L (left) to L, R (right) to R, “+” to “+”, and “−” to “−”. For information regarding the connection procedure, refer to the owner’s manual for your speakers.

■ Using banana plug cables

(Models for U.S.A., Canada, Australia, China, and Taiwan)

First tighten the knob on the SPEAKERS terminal, and then insert the banana plug into the head of the knob.

A bi-wired connection separates the woofer from the mid and high ranges. Speakers that support bi-wired connection feature two pairs of terminals (total four terminals). These two pairs of terminals can divide the speakers into two independent parts. To make this kind of connection, you need to connect mid and high range drivers to one pair of terminals, and low range drivers to the other pair of terminals.

1 Remove the shorting bars or bridges on the

speakers.

2 Connect this unit to the speakers as shown

in the figure below.

An example of left channel connection

■ Using Y-shaped lug cables

1 Unscrew the knob, and then sandwich the

Y-shaped lug between the ring part and base of the terminal.

2 Tighten the knob.

■ Operating the unit from another room

If you connect a commercially-available infrared receiver and transmitter to the unit’s REMOTE IN/OUT jacks, you will be able to operate the unit and/or external component from another room, using the supplied remote control.

When the power to the connected component is turned on, the power to this unit is also turned on. Simultaneously, the input source to the unit is set to MAIN DIRECT. If MAIN DIRECT has been selected as the input source for this unit, when the power to the connected component is turned off, this unit will enter standby mode.

Note

When the power switch on this unit is turned Off, the power to the unit will not be triggered.
