In doing this, the apparent position between the front (left and right) speakers and subwoofer will appear equal to the driver. After performing above, you can change the positions of left and right speakers by delaying the time.

•If HPF, LPF, bass control and treble control are all set to ON, depending on the bass control and treble control settings, you may not be able to reinforce the sound effect.

•Except when the HPF and LPF is turned OFF, the subwoofer is in monaural mode.
