	Standby Lit dimly
Down position Off	Off

While the ⏻ (Power) switch is in the up position, press the ⏻ 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 ⏻ (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.

VOLUME AUDIO MUTE

② Remote control sensor

Receives signals from the remote control. (→ page 14)

③PHONES jack

Connect your headphones here.

Note

• Connecting the headphones here will result in the following:
• No sound will be heard from the connected speakers.
• Audio signals will not be output at the PRE OUT jacks.
• You will be unable to select MAIN DIRECT as the input source.
• If MAIN DIRECT is selected as the input source, audio signals will not be output at the PHONES jack.

④SPEAKERS selector

Switches sets of speakers connected to the SPEAKERS L/R CH A and B terminals on the rear panel as follows:

OFF: No audio signals will be output from the speakers.

A: Audio signals will be output from the set of speakers connected to the A terminals.

B: Audio signals will be output from the set of speakers connected to the B terminals.

A+B BI-WIRING: Audio signals will be output from the sets of speakers connected to the A and B terminals. Select this position when you plan to make a bi-wired connection. (→ page 19)

NOTICE

[Model for Asia]

If you connect two sets of speakers (A+B), use the speakers with an impedance of 12Ω or higher.

Connections

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.

Connecting speakers

■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.

10 mm

2Unscrew the knob on each speaker terminal, and then insert the bare wire into the side hole on the terminal.

Diagram showing a mechanical assembly process with labeled components and directional arrow

Diameter of the speaker cable wire hole: 6.0 mm

3Tighten 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.

Banana plug Diameter of the banana plug hole: 4.0 mm

■Using Y-shaped lug cables

1Unscrew the knob, and then sandwich the Y-shaped lug between the ring part and base of the terminal.

Y-shaped lug This is a part of the

Thickness of the terminal core: 5.8 mm

2Tighten the knob.

Bi-wired connection

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.

2Connect this unit to the speakers as shown in the figure below.

	The speaker cables are not connected properly.	Make sure that the speaker cables are connected properly.	18
The sound is suddenly muted.	The protection circuitry has been activated because of a short circuit, etc.	Make sure that the speaker wires are not touching each other or shorting out against the rear panel of the unit, and then turn on the power to the unit.	18
The volume level cannot be adjusted.	MAIN DIRECT is selected as the input source.	Adjust the volume level on the connected component.Alternatively, connect the external component to a pair of the input jacks other than the MAIN IN jacks, and then select the corresponding input source.	8
Only one channel speaker can be heard.	The playback component or speakers are not connected properly.	Make sure that they are connected properly. If the problem persists, the cables might be defective.	16
	The volume level balance between the left and right speakers is not adjusted properly.	Adjust the volume level balance between the left and right speakers properly using the BALANCE control.	8

Appendix

Problem Cause Remedy			See page
There is a lack of bass and no ambience.	The + and - wires are connected in reverse at the amplifier or the speakers.	Connect the speaker wires to the correct + and - phase.	18
A “humming” noise is heard.	Incorrect input or output cable connections.	Connect the cables properly. If the problem persists, the cables might be defective.	16
	The turntable is not grounded to the GND terminal.	Connect the turntable to the GND terminal of this unit.	16
Playback audio is distorted while you listen to a connected CD player or tape deck through headphones (that are connected to a CD player or tape deck).	The power to the unit is turned off. Turn on the power to the unit. 6
The volume level of the vinyl record is too low.	The MM/MC switch on the rear panel is set incorrectly.	Set the MM/MC switch to the MM or MC position according to the type of magnetic cartridge of the turntable.	10
The remote control does not work or function properly.	The remote control has been used out of the operating range.	The remote control must be used within a maximum distance of 6 m and no more than 30 degrees off-axis from the remote control sensor on the front panel.	14
	Direct sunlight or lighting (from an inverter type of fluorescent lamp, strobe light, etc.) is hitting the remote control sensor on the front panel.	Change the orientation of the lighting or reposition the unit.	—
	The batteries are weak. Replace all batteries. 14

Maintenance

Mirror-finish side panels

We recommend that you use a cleaning cloth such as those made for pianos.

Other surfaces

Do not use chemical agents, such as benzene or thinner for cleaning. Otherwise, the surfaces might be damaged. Wipe the surfaces using a soft dry cloth.
