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.

(2) Remote control sensor
Receives signals from the remote control. (→ page 14)
(3) PHONES 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.

(4) TRIM selector
Switches the headphone amp gain. Select the gain setting that is appropriate for your headphones.
Available gain: -6 dB, 0 dB, +6 dB, +12 dB

(5) SPEAKERS 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.

Connections

This section explains how to connect the unit to speakers and audio source components.

Connection diagram

CAUTION
Be sure to complete all connections before plugging in the power cable to an AC outlet. ( → page 22)

NOTICE
If a component is connected to the MAIN IN jacks, the unit’s volume level will be fixed. Therefore, do not connect a CD player or other components that do not feature volume adjustment to the MAIN IN jacks. Otherwise, a loud sound may be emitted, resulting in malfunction of the unit or damage to the 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.

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.

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.

■ 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.

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

An example of left channel connection

3 Set the SPEAKERS selector on the front panel to A+B BI-WIRING.

Balanced connection

You can connect a CD player or network player that features XLR-type balanced output jacks to the BAL input jacks of this unit. Use XLR-type balanced cables for this connection.
ATTENUATOR selector: Enables you to set the allowable input level at the balanced input jacks. Select ATT. (-6 dB) if the audio output from the connected component sounds distorted.
PHASE selector: Enables you to set the position (phase) of the HOT pin (pin #2: HOT or pin #3: HOT) at the balanced input jacks.

Refer to the instruction manual for the connected component to find out the position of the HOT pin at the balanced output jacks on the component.

Note

• Select NORMAL (pin #2 is HOT) for a Yamaha player.
• Do not use balanced and unbalanced connections for one component simultaneously. Doing so would create a ground loop that could generate static and noise.
• When connecting a cable, be sure to align the pins on the connector with the holes on the jack, and then insert the male XLR connector into the jack until you hear a click. To remove the cable, while pressing and holding down the lever on the BAL input jack, pull out the male XLR connector from the jack.

• For a balanced connection, select BAL as the input source.

Trigger connection

You can connect a Yamaha AV receiver or other component that supports the Trigger function. You can control this unit in sync with a connected component.
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.

Remote connection

■ 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.

■ Remote connection between Yamaha components

If you have another Yamaha component that supports remote connections, an infrared transmitter is not necessary. Connect an infrared receiver to the unit’s REMOTE IN/OUT jacks, as shown below. Up to 3 Yamaha components (including this unit) can be set up for remote connection.

Connecting the power cable

After all connections are complete, plug the power cable into the AC IN connector of the unit, and then plug the power plug into the AC outlet.
