bINPUT SELECT switch

This switch is located between the balanced input and single-ended RCA input for each channel. Use this switch to select the input type for its channel.

When setting the switch to the upper side, the bal- anced input is selected.

When setting the switch to the lower side, the RCA audio input is selected.

Notes:

•Do not change the INPUT SELECT switch setting when the amplifier is turned on.

•Make sure that connections have been made only to the inputs selected with the INPUT SELECT switches and nothing is connected to the other ones.

cUnbalanced Input (single end RCA input)

Connect AV controllers or control amplifiers with single-ended outputs.

RCA type

Notes:

•When using this single-ended connection for a spe- cific channel, set the INPUT SELECT switch to the lower side (the RCA audio input side), use commer- cial RCA audio pin cable and connect the single- ended outputs.

•Do not connect anything to the balanced input jack.

dOUTPUT (Speaker output and binding post)

These terminal posts are for connecting the front L/R, center, surround L/R, surround back L/R, and front high/wide L/R speakers.

The FRONT L/R and SURR BACK L/R terminal posts can be used with front speakers and surround back speakers respectively, or used to bi-amp the front speakers. See “Bi-amping the Front Speakers” on page 15.

eSPEAKER IMPEDANCE switch

Use this switch to select the speaker impedance. 4Ω: Select if the impedance of any speaker is

4 ohms or more but less than 6.

6Ω: Select if the impedances of all speakers are between 6 and 16 ohms.

fAUTO POWER DOWN switch

You can use the auto power-down function. If the amplifier receives no signal for 3 hours, it will auto- matically enter standby mode. Once the auto power- down function has been activated, the amplifier will not automatically turn on even if it receives the sig- nal. To turn on the amplifier, press the ON/STANDBY button manually. You can also dis- able the function by setting this switch to OFF side. Default setting: ON (European models), OFF

(North American and Asian models)

Notes:

•Regardless of the position of this switch, this function will not work when the amplifier has been turned on by the 12V trigger.

•Before entering standby mode by the auto power- down function, the amplifier notifies you by flashing the ON indicator for 10 seconds.

•Depending on some sources, the auto power-down function may activate during playback.

g12V TRIGGER IN

Connects to the 12V trigger output terminal on the other component to control the amplifier. This enables the amplifier to turn on or go into standby state based on the power on/standby status of the connected component.

Use the supplied or commercially available 1/8-inch mono cable to connect to the 12V trigger output ter- minal on the other device.

The tip polarity of the connectors are as shown below.

5 to 12 volts, positive tip polarity

hAC INLET

Plug the supplied power cord into this AC INLET and then into the power outlet on the wall.

Power cord (supplied)

To an AC wall outlet

•Do not plug the amplifier into the AC outlet other than an AC wall socket.

•Do not use a power cord other than the one supplied with the amplifier. The power cord supplied is designed for use with the amplifier and should not be used with any other device.

•Never have the power cord disconnected from the amplifier while the other end is plugged into the wall outlet. Doing so may cause an electric shock. Always connect by plugging into the wall outlet last and dis- connect by unplugging from the wall outlet first.

•Before you plug in the amplifier, confirm that all con- nections have been made properly.

•Turning on the power may cause a momentary power surge, which might interfere with other electrical equipment on the same circuit, such as computers. If this happens, use a wall outlet on a different circuit.
