Yamaha R-S700BL ユーザーズマニュアル

■ Adjusting the BASS and TREBLE 

The BASS and TREBLE controls adjust high and low 
frequency response.
The center position produces a flat response.

BASS
When you feel there is not enough bass (low frequency 
sound), rotate clockwise to boost. When you feel there is 
too much bass, rotate counterclockwise to suppress.
Control range: –10 dB to +10 dB (20 Hz)

TREBLE
When you feel there is not enough treble (high frequency 
sound), rotate clockwise to boost. When you feel there is 
too much treble, rotate counterclockwise to suppress.
Control range: –10 dB to +10 dB (20 kHz)

■ Adjusting the BALANCE control

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.

■ Adjusting the LOUDNESS control

Retain 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.

If the CD DIRECT AMP switch (R-S700 only) or the 
PURE DIRECT switch 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 switch (R-S700 only) or the PURE DIRECT switch 
after lowering the sound output level or after checking that 
the LOUDNESS control is properly set.

y

After setting the LOUDNESS control, enjoy listening to music at 
your preferred volume level. If the effect of the LOUDNESS 
control setting is too strong or weak, readjust the LOUDNESS 
control.
