IMPORTANT SAFETY INSTRUCTIONS

CAUTION

RISK OF ELECTRIC SHOCK

DO NOT OPEN

CAUTION: TO REDUCE THE RISK OF

ELECTRIC SHOCK, DO NOT REMOVE

COVER (OR BACK). NO USER-SERVICEABLE

PARTS INSIDE. REFER SERVICING TO

QUALIFIED SERVICE PERSONNEL.

• Explanation of Graphical Symbols

The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert you to the presence of uninsulated “dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons.

The exclamation point within an equilateral triangle is intended to alert you to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance.

IMPORTANT

Please record the serial number of this unit in the space below. MODEL: Serial No.: The serial number is located on the rear of the unit. Retain this Owner’s Manual in a safe place for future reference.

1 Read these instructions. 2 Keep these instructions. 3 Heed all warnings. 4 Follow all instructions. 5 Do not use this apparatus near water. 6 Clean only with dry cloth. 7 Do not block any ventilation openings. Install in accordance

with the manufacturer’s instructions.

8 Do not install near any heat sources such as radiators, heat

registers, stoves, or other apparatus (including amplifiers) that produce heat.

9 Do not defeat the safety purpose of the polarized or

grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide blade or the third prong are provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.

10 Protect the power cord from being walked on or pinched

particularly at plugs, convenience receptacles, and the point where they exit from the apparatus.

11 Only use attachments/accessories specified by the

manufacturer.

12 Use only with the cart, stand, tripod,

bracket, or table specified by the manufacturer, or sold with the apparatus. When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over.

13 Unplug this apparatus during lightning storms or when

unused for long periods of time.

14 Refer all servicing to qualified service personnel. Servicing

is required when the apparatus has been damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.

We Want You Listening For A Lifetime

YAMAHA and the Electronic Industries Association’s Consumer Electronics Group want you to get the most out of your equipment by playing it at a safe level. One that lets the sound come through loud and clear without annoying blaring or distortion – and, most importantly, without affecting your sensitive hearing. Since hearing damage from loud sounds is often undetectable until it is too late, YAMAHA and the Electronic Industries Association’s Consumer Electronics Group recommend you to avoid prolonged exposure from excessive volume levels.

Increases or decreases the low frequency response. The 0 position produces a flat response. See page 13 for details.

B TREBLE

Increases or decreases the high frequency response. The 0 position produces a flat response. See page 13 for details.

C BALANCE

Adjusts the sound output balance of the left and right speakers to compensate for sound imbalances caused by speaker locations or listening room conditions. See page 13 for details.

D LOUDNESS

Retains a full tonal range at any volume level to compensates for the human ears’ loss of sensitivity to high and low-frequency ranges at low volume. See page 13 for details.

E REC OUT selector

(AX-497 only)

Selects a source for recording to the MD recorder or the tape deck independently of the INPUT selector setting, allowing you to record the selected source while listening to another source. See page 14 for details.

F VOLUME

Installing batteries in the remote control

1 Open the battery compartment cover.

2 Insert two supplied batteries

(AAA, R03, UM-4) according to the polarity markings (+ and –) on the inside of the battery compartment.

3 Close the cover back.

■ Notes on batteries

• Change all of the batteries if you notice the following conditions; the operation range of the remote control decreases, the indicator does not flash or its light becomes dim.

• Use AAA, R03, UM-4 batteries.

• Make sure that the polarities are correct. See the illustration inside the battery compartment.

• Remove the batteries if the remote control is not used for an extended period of time.

• Do not use old batteries together with new ones.

• Do not use different types of batteries (such as alkaline and manganese batteries) together. Read the packaging carefully as these different types of batteries may have the same shape and color.

• We strongly recommend using alkaline batteries.

• If the batteries have leaked, dispose of them immediately. Avoid touching the leaked material or letting it come into contact with clothing, etc. Clean the battery compartment thoroughly before installing new batteries.

• Do not throw away batteries with general house waste; dispose of them correctly in accordance with your local regulations.

Using the remote control

The remote control transmits a directional infrared beam. Be sure to aim the remote control directly at the remote control sensor on the front panel of this unit during operation.

CONNECTIONS

Connecting speakers and other components

CAUTION

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

• Do not let the bare speaker wires touch each other or do not let them touch any metal part of this unit. This could damage this unit and/or the speakers.

• All connections must be correct: 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. Also, refer to the owner’s manual for each of your components.

• Use RCA type pin plug cables for audio/video units except speakers.

• Connect your turntable to the GND terminal to reduce noise in the signal. However, you may hear less noise without the connection to the GND terminal for some record players.

■ Adjusting the BALANCE control

Adjusts the sound output balance of the left and right speakers to compensate for sound imbalance caused by speaker locations or listening room conditions.

BALANCE

■ Using the CD/DVD DIRECT AMP switch

Routes input signals from your CD or DVD player directly to the specially built-in amplifier for the CD or DVD player. As a result, the input signals bypass the INPUT selector and the BASS, TREBLE, BALANCE and LOUDNESS controls (and the TAPE MONITOR switch for AX-397 only) and then sent to the power amplifier, thus eliminating any alterations to the CD or DVD signals and creating the purest possible sound.

CAUTION

If the CD/DVD DIRECT AMP switch (or the PURE DIRECT switch for AX-497 only) 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 undesirably damaged, be sure to press the CD/DVD DIRECT AMP switch (or the PURE DIRECT switch for AX-497 only) AFTER lowering the sound output level or AFTER checking that the LOUDNESS control is properly set.
