Adjusting the tonal quality

■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.

■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.

PLAYING AND RECORDING

■Adjusting the LOUDNESS control

Retains a full tonal range at any volume level, thus compensating for the human ears’ loss of sensitivity to high and low-frequency ranges at low volume.

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.

1Set the LOUDNESS control to the FLAT position.

AX-397, AX-497 specifications

The Yamaha AX-497 and AX-397 are two notable integrated amplifiers from Yamaha's renowned hi-fi audio lineup, designed to deliver exceptional sound quality and performance for audiophiles and music enthusiasts alike. While both models share a strong foundation, they exhibit distinct features and technologies that cater to different listening preferences.

The Yamaha AX-497 is the more advanced of the two, boasting a power output of 80 watts per channel at 8 ohms, which provides ample power for driving various speakers effectively. The AX-497 utilizes Yamaha's proprietary ToP-ART (Total Purity Audio Reproduction Technology) design, which focuses on preventing signal degradation and ensuring a clean, natural sound. This model features a discrete amplifier configuration, providing lower distortion levels and a more dynamic soundstage.

One of the standout features of the AX-497 is its comprehensive tone control system. Users can finely adjust the bass, treble, and balance, allowing for personalized sound tailored to individual preferences and room acoustics. Additionally, the AX-497 includes a direct input for bypassing tone controls during critical listening sessions, effectively providing an uncolored sound reproduction.

On the other hand, the Yamaha AX-397 offers a slightly reduced power output of 60 watts per channel at 8 ohms, making it suitable for smaller speaker systems and listening environments. Despite this lower output, the AX-397 still maintains an impressive sound quality, thanks to a similar ToP-ART design that ensures purity in audio reproduction.

The AX-397 is equipped with a high-quality phono stage, allowing for a seamless connection with turntables, which is becoming increasingly popular among vinyl enthusiasts. Additionally, it features a simple yet elegant user interface with easy-to-use controls for volume, input selection, and tone adjustments.

Both models utilize a robust build quality, reflecting Yamaha's commitment to durability and longevity. The sleek design of the amplifiers complements any audio setup, adding a touch of sophistication.

In summary, the Yamaha AX-497 and AX-397 integrated amplifiers are distinguished by their power outputs, features, and target users. The AX-497 is ideal for those seeking higher power and extensive control over sound, while the AX-397 suits casual listeners who appreciate quality sound in a more compact form. Regardless of the choice, both amplifiers exemplify Yamaha's dedication to delivering superior audio experiences.
