5 KEY FEATURES
Digital Inputs, Outputs and Component Video
Many A/V receivers and TVs do not have multiple digital audio and component video inputs.
As a result, adding a new piece equipment can force the need for the entire system be
upgraded. The VS-712 EX handles both optical and co-axial digital audio, as well as high
bandwidth HDTV component video.
Automatic Input Sensing
When you turn on a piece of equipment, the VS-712 EX detects the new device, turns on and
automatically activates that input, without the need to push any buttons. Heres how:
Turn on your VCR and the VS-712 EX selects the VCR input and feeds it to the VIEW output.
Turn on your DVD unit and it will automatically select the DVD. Or select any input using
the I/R Remote or the front panel buttons. The RECORD output is dedicated to the manually
selected input, so recording is not interrupted by VIEW changes.
Automatic Volume Stabilization
Too often we strain to hear soft dialogue in the movies, but cringe when the special
effects kick in. Auto Volume Stabilization enables the VS-712 EX to generate a more
enjoyable balance by moderating the dynamic audio range. The volume compression setting
pulls loud and soft sounds toward a mid-point in the dynamic range. (Loud gets softer,
soft gets louder.) The volume expansion setting enhances the extremes. (Loud gets louder,
soft gets softer.)
Two Independent Output Channels
Two outputs let you select one source for viewing (like the DVD) to watch on your TV and a
second source for recording (like the DSS) to feed to your VCR for recording at the same
Video Up Converting
Unlike other low-end A/V switchers, the VS-712 EXs unique circuitry does video
signal conversion automatically. This is useful when the home theater has a combination of
composite video, s-video and component video signals. Composite video will be converted to
s-video and component, and s-video will be converted to component. This allows the
television to be set to one input, regardless of the video type.
