Yamaha RX-397 用户指南

A VOLUME
Increases or decreases the sound output level.

This does not affect the OUT (REC) level.

B INPUT selector
Selects the input source you want to listen to.

C A/B/C/D/E
Selects the preset station group (A to E) when TUNER is 
selected as the input source (see page 22).

D PHONES jack
Outputs audio for private listening with your headphones.

Press SPEAKERS A and B so that the SP A/B indicators turn off 
before you connect your headphones to the PHONES jack.

E SPEAKERS A/B
Turns on or off the speaker set connected to the 
SPEAKERS A and/or SPEAKERS B terminals on the rear 
panel each time the corresponding button is pressed (see 
page 15).

F BASS
Increases or decreases the low frequency response. The 0 
position produces a flat response (see page 16).

G TREBLE
Increases or decreases the high frequency response. The 0 
position produces a flat response (see page 16).

H 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 
16).

I LOUDNESS
Retains a full tonal range at any volume level to 
compensate for the human ears’ loss of sensitivity to high 
and low-frequency ranges at a low volume level (see page 
16).

J Preset station number buttons 

Selects the preset station number (1 to 8) directly when 
TUNER is selected as the input source (see page 24).
