From this point on the volume control on your receiver preamplifier will control the overall volume of your system including the subwoofers The front panel MUSIC VIDEO MODE switch and VIDEO BASS CONTOUR allow you to optimize the VT 3s for music listening or movie viewing giving you the best of both worlds When watching a movie there is often a disparity between the size of the sonic space and the size of the visual space presented to you Your eyes tell you that events are occurring in a large space for example while your ears tell you that events are occurring in a space roughly the size of your room Activating the rear firing drivers enhances the soundstage allowing a closer match between sonic and visual spaces The rear firing drivers can be switched off if the enhancement is not desired Similarly when listening to music many listen ers prefer a flat bass response that does not emphasize any individual frequencies Flat bass response more realistically reproduces the sound of live instruments However when watching movies in a home theater system many listeners pre fer a punchier boomier sound that emphasizes sounds like explosions and gunfire Subwoofers with more output in the mid bass region tend to deliver this punch at the expense of flat response The Music Video Mode switch allows you to add mid bass punch if you so desire The MUSIC VIDEO MODE switch determines the operating mode of the VT 3 In the MUSIC mode the VT 3
