[AUDIO]
Controlling Sound [VOLUME/BASS/TREBLE/BALANCE]
Adjusts the volume, bass and treble level, left and right balance of the projector speaker and AUDIO OUT (Stereo
Mini Jack).
TIP:
[VOLUME]
• When no menus appear, the  and  buttons on the projector cabinet and the VOL. +/− buttons work as a volume control. ( →
page 30)
[BALANCE]
• When the left/monaural of the video/component audio input is connected, the right and left channel sound from the AUDIO OUT
(Stereo Mini Jack) is the same.
Enabling 3D Surround [3D SURROUND]
Turn on or off the 3D surround effect.
NOTE: When the AUDIO OUT (Stereo Mini Jack) of the projector is connected to an external equipment, audio control on the
external equipment may cause distorted or scratchy sound depending on the adjustments of BASS, TREBLE, BALANCE and 3D
SURROUND. If this happens, return the adjustments of the projector to the factory preset ("0" for [BASS], "0" for [TREBLE], and
"OFF" for [3D SURROUND]).
