ADJUSTING LOW FREQUENCY SOUND
EFFECT(LFE)
The disc recorded in Dolby Digital surround contains special
signals called LFE to enhance low frequency sound effect. The
LFE signals are recorded in some particular parts on the disc
and output from the connected sub-woofer to reproduce
astonishingly powerful low sound.
The sound level of the LFE signals can be adjusted according to
your speakers connected while the Dolby Digital surround is
activated.

When connecting a sub-woofer, select “SUBW ON”
(see page 5).

1 Press the N (UP) or M (DOWN) button and hold
it down until “LFE” is displayed.
2 Press the N (UP) or M (DOWN) button
repeatedly or turn the MULTI JOG to adjust the
