YHF-397BG Stereo Component System

High Quality Sound

Pure Direct Switch

When this switch is engaged, the signal
bypasses the tone, loudness, balance
controls, and other circuit, being fed
directly to the discrete power amplifier. It
travels in a straight line from the volume
control, through the high-gain short,
direct path for maximum signal purity.

Super Audio CD and DVD-Audio
Ready with Extended Frequency
Response

Rather than the usual 20Hz–20kHz
frequency response, Yamaha has given
the RX-397 the ability to handle
frequencies from 10Hz to100kHz (1dB).
Although the ear cannot hear the higher
frequencies, it has been proven that these
harmonics can affect sound reproduction
quality. Super Audio CD, DVD-Audio and
other new formats will be able to output
sound over this range, so the RX-397 is
fully compatible with products using thes e
formats.

Linear Damping

Level variations due to high amp
impedance tend to reduce an amplifier’s
damping factor, and frequency variations
cause it to fluctuate. This circuit cancels
the effect of these variations, maintaining
a high, stable damping factor, for superior
articulation of all sounds and better
frequency response.

High Dynamic Power, Low­Impedance Drive Capability

The RX-397B is capable of delivering
large amounts of reserve power for
accurate reproduction of high energy
peaks. This emphasizes the music’s
dynamic qualities and provides a
sharper sound image.

Discrete Amplifier Configuration

The CDX-397 ‘s CD buffer amplifier,
volume control amplifier and power
amplifier are all constructed from carefully
selected discrete parts. This configuration
provides superior signal quality.

Intelligent Digital Servo System

Conventional tracking servo circuitry
cannot completely overcome errors
caused by disc defects, war page, dust
and so on. This system uses a
microcomputer to monitor the signal,
adjusting pickup tracking and focus, as
well as spindle motor speed, to
compensate for any problems.

Low-Impedance Power Supply

Because every signal part affects sound
quality, Yamaha uses nothing but the
best. The special Low-Impedance Power
Supply, in the CDX-397B uses extra thick
wires to ensure that power is absolutely
stable even under low impedance
conditions.

Display Dimmer

The CDX-397’s front display dimmer
function lets you dim the display when

you darken the room to suit your mood
while listening to music. The brightness of
the display can be set to Normal, Slightly
Dim and Dim. Dimming the display also
reduces any chance of noise interference
from the LCD for highest audio quality.

Aluminium Front Panel

An aluminium front panel is used to
effectively shield sensitive low-level
circuitry from external noise and
electronic radiation generated by dimmer
switches, HVAC, fluorescent lighting and
video displays (CRT, LCD, Plasma).

Convenient Operation

CD-R/RW Playback

The CDX-397B CD players can handle CD­R and CD-RW discs with ordinary songs.
(Note that some discs may not play.)

Wealth of Playback Functions

In addition to ordinary play, there are a
variety of ways you can enjoy the musical
selections on your CDs. Random Play
plays all the songs in a random order. If
you want to hear them in a certain order,
you can use the 40-Track Program Play
function. There are also several repeat
modes: Single Track, Entire Disc, Random
Play, Programme Play and A-B (for
repeating all songs between two
points on the disc).

Auto Space Insert

Lets you add a short pause at the touch
of a button on the remote control while
recording to ensure that there is sufficient
space between selections.

3-Mode CD Text Display

Get information about the CD currently
playing right on the CD player’s display.
The 3-mode CD Text display shows the
CD’s title, the artist’s name and the title of
the track.

Peak Search

Gives you better sounding recording by
searching the disc for the loudness part
and playing it for a few seconds so you
can set the proper recording level.

CD-Tape Synchronised Record Start

You’ll have smooth recording starts each
time, because Synchronised Record Start
puts the deck into the recording mode a
few seconds before starting CD play.

RoHS Compliant

This environmentally friendly unit fully
complies with the EU’s RoHS (Restriction
of Hazardous Substances) standards.

Speaker Design

Speaker Cabinet Has New Design
with Innovative Cross-Bracing

The cabinet is built with internal cross­bracing having a unique wedge structure.
R-beveling reduces diffraction effects.
This type of cross braced structure is used
in top class speakers and Yamaha
engineers are able to make the most of its
advantages. It produces a tighter sound
and the increased strength cuts down
unwanted vibration.

Simply, Cosmetic Design Concept

This system provides Hi-Fi component-like
design that same dedication to sound and
design excellence is behind the creation of
the top-class component.

Beautiful Yamaha Piano Finish
Speakers

As the world’s leading piano
manufacturer, Yamaha has a long history
of woodworking expertise. The E810
speakers have the same luxurious and
environmentally friendly finish as
our grand pianos.
