CONTROLS AND FUNCTIONS

Installing batteries

Operation range
Point the remote control at the remote control sensor on this unit and remain within the operating range shown below.

Notes on remote control and batteries

• The area between the remote control and this unit must be clear of large obstacles.
• Be careful not to spill water or other liquids on the remote control.
• Be careful not to drop the remote control.
• Do not leave or store the remote control in the following conditions:
  • places of high humidity, such as near a bathroom
  • places of high temperatures, such as near a heater or stove
  • places of extremely low temperatures
  • dusty places
• Change all batteries if you notice the operation range of the remote control narrows.
• If the batteries run out, immediately remove them from the remote control to prevent an explosion or acid leak.
• If you find leaking batteries, discard the batteries immediately, taking care not to touch the leaked material. If the leaked material comes into contact with your skin or gets into your eyes or mouth, rinse it away immediately and consult a doctor. Clean the battery compartment thoroughly before installing new batteries.
• Do not use old batteries together with new ones. This may shorten the life of the new batteries or cause old batteries to leak.
• Do not use different types of batteries (such as alkaline and manganese batteries) together. Batteries that look the same may have a different specification.
• Dispose of batteries according to your regional regulations.
• Keep the batteries in a location out of reach of children. Batteries can be dangerous if a child were to put in his or her mouth.
• If you plan not to use this unit for a long period of time, remove the batteries from this unit. Otherwise, the batteries will wear out, possibly resulting in a leakage of battery liquid that may damage this unit.

CONNECTIONS

Connecting speakers and source components

Make sure to connect L (left) to L, R (right) to R, “+” to “+” and “–” to “–”. If the connections are faulty, no sound will be heard from the speakers, and if the polarity of the speaker connections is incorrect, the sound will be unnatural and lack bass. Refer to the owner’s manual for each of your components. Make sure to use RCA cables or optical cable to connect audio components

CAUTION
Do not connect this unit or other components to the main power until all connections between components are complete.

Only PCM signals can be input to the DIGITAL (OPTICAL/COAXIAL) jacks of this unit. For details on the supported PCM signals, see page 15.

The PHONO jacks are designed for connecting a turntable with an MM cartridge. Connect your turntable to the GND terminal to reduce noise in the signal. However, for some turntables, you may hear less noise without the GND connection.

REC jacks

• The audio signals are not output via the LINE 2 REC or LINE 3 REC output jacks when LINE 2 or LINE 3 is selected with the INPUT selector.
• The VOLUME, BASS, TREBLE, BALANCE and LOUDNESS controls and the CD DIRECT function (or the PURE DIRECT function) have no effect on the source being recorded.

Connecting speaker cables

• Remove approximately 10 mm (3/8 in) of insulation from the end of each speaker cable.
• Twist the bare wires of the cable firmly together.
• Unscrew the knob.
• Insert one bare wire into the hole in the side of each terminal.
• Tighten the knob to secure the wire.

CAUTION

• Set the IMPEDANCE SELECTOR switch according to the impedance of the speakers to be connected (see page 5).
• Do not let bare speaker wires touch each other or any metal part of this unit. This could damage this unit and/ or the speakers.

Connecting via banana plug (North America, General, China and Australia models only)

• Tighten the knob.
• Insert the banana plug into the end of the corresponding terminal.

Bi-wire connection
In the case of speakers supporting the bi-wiring connection, the tweeter/midrange unit and woofer of the speakers can be driven independently through connections shown in the following figure, allowing you to enjoy clear mid- and high-range sounds

Note

When making bi-wire connections, remove the shorting bridges or cables on the speaker. Refer to the speakers’ instruction manuals for more information. To use the bi-wire connections, set the SPEAKERS selector on the front panel to the A+B BI-WIRING position

Connecting power cable

General model only)

Before connecting the power cable, make sure you set VOLTAGE SELECTOR of this unit according to your local voltage. Improper setting of VOLTAGE SELECTOR may cause fire and damage to this unit.

AC IN (A-S701)
Connect the supplied power cable to AC IN after all other connections are complete.

Power cable (A-S501/S301)
Connect the power cable to an AC wall outlet after all other connections are complete

PLAYBACK

Playing a source

• Rotate the VOLUME control on the front panel fully counter-clockwise so as not to play sounds loud suddenly.
• Press A (power) switch on the front panel inward to turn on this unit.
• Rotate the INPUT selector on the front panel (or press one of the Input selector buttons on the remote control) to select the input source you want to listen to.
• The indicator for the selected input source lights up.
• Rotate the SPEAKERS selector on the front panel to select SPEAKERS A, B or A+B BIWIRING.
• Set the SPEAKERS selector to the A+B BI-WIRING position when two sets of speakers are connected using bi-wire connections, or when using two sets of speakers simultaneously (A and B).
• Play the selected input source.
• Rotate the VOLUME control on the front panel (or press VOLUME +/– on the remote control) to adjust the sound output level.
• You can adjust to the desired sound by using the BASS, TREBLE, BALANCE and LOUDNESS controls, the CD DIRECT AMP button, or the PURE DIRECT button on the front panel.
• When finished listening, press A (power) switch on the front panel outward to turn off this unit.
• If A AMP on the remote control is pressed while the A (power) switch on the front panel is in the on position, this unit enters standby mode. Press A AMP again to turn this unit on.

Adjusting to the desired sound

Making it easier to hear the high- and low-frequency ranges even at low volume (LOUDNESS)

Enjoy natural sound even at low volume by lowering the mid-range sound level and compensating for the human ears’ loss of sensitivity to high- and low-frequency ranges at low volume.

CAUTION
If the CD DIRECT AMP function (or the PURE DIRECT function) is turned on with the LOUDNESS control set at a certain level, the input signals bypass the loudness control, resulting in a sudden increase in the sound output level. To prevent your ears or the speakers from being damaged, be sure to press the CD DIRECT AMP button (or the PURE DIRECT button) AFTER lowering the sound output level or AFTER checking that the LOUDNESS control is properly set.

• Set the LOUDNESS control to the FLAT position.
• Rotate the VOLUME control on the front panel (or press VOLUME +/– on the remote control) to set the sound output level to the loudest listening level that you would listen to.
• Rotate the LOUDNESS control counterclockwise until the desired volume is obtained.

Reproducing pure, high fidelity sound (PURE DIRECT)
When the PURE DIRECT function is on, noise can be reduced by bypassing the circuit that the audio input signal is not using and stopping the power supply to the circuit. Therefore, in all input sources, you can enjoy music playback in straight and high quality sound. The indicator above the PURE DIRECT button lights up when this function is turned on.

Note
The BASS, TREBLE, BALANCE and LOUDNESS controls do not function while the PURE DIRECT function is turned on.

Reproducing CD sound with the highest sound quality (CD DIRECT AMP) (A-S701 only)

When selecting the input source other than CD, if you press the CD DIRECT AMP button, the input source switches to CD.

CD Direct Amp feature
Stop power supply to the unnecessary circuit for CD playback, convert the input signal to the normal phase and reverse phase, and balance transfer to the electronic volume. With the following effects, a more faithful sound to the original will be provided.

• improved signal-to-noise ratio
• external noise canceling
• reduced distortion

Notes

• The BASS, TREBLE, BALANCE and LOUDNESS controls do not function while the CD DIRECT AMP function is turned on.
• Be sure to connect the CD player to the CD input jacks if you use the CD direct function.
• The CD DIRECT AMP function is turned off if the following operation is performed.
• Select an input source other than CD for the INPUT selector.
• The PURE DIRECT function is turned on.
