APPLICATIONS FEATURES

Extron’s SVS 100 is a four input, one output, video switcher that
improves presentation quality by providing seamless vertical
interval switching without the need to genlock the sources.
Applications such as videoconferencing, distance learning, video
editing, and staging benefit from the cost-effective SVS 100, which
makes glitch-free switches without using expensive genlocking
equipment. By eliminating loss of sync during switching and by
color matching inputs, the SVS 100 enhances the professional
look of your presentations. Without color correction, the appearance
of specific colors can differ dramatically from source to source.
Individual settings required by each input source are also saved
for consistent color, tint, brightness, and contrast levels, ensuring
that colors match between multiple sources. Video images are
routed from sources such as VCRs, DVD players, scan converted
PCs, laserdisc players, videoconferencing CODECs, or document
cameras. For routing audio associated with any video input, the
SVS 100 features a four input, one output stereo audio switcher
with audio attenuation/gain.

The SVS 100 is compatible with NTSC or PAL signals and offers
composite and S-video inputs. Each input also offers a loop-out
for a local monitor. Three outputs are available simultaneously as
two composite video outputs and one S-video output. For switching
between inputs, the SVS 100 provides a seamless “cut” and a variety
of “wipe,” “dissolve,” and “fade” effects. The 24 digital transition
effects include left to right, right to left, top to bottom, and so forth.
Each effect has a user-adjustable duration ranging up to five seconds.

Color, tint, contrast, and brightness controls are provided per
input for color correction of each source signal. The SVS 100
provides up to 128 user preset memories, which saves color
adjustment settings for use with matrix switchers. Extron’s easy­to-use Simple Instruction Set (SIS™) is provided to call up any
preset via RS-232 control. Unlike typical strings of lengthy,
tedious RS-232 programming code, SIS commands are
convenient and easy to enter. The use of the SVS 100’s presets
ensures consistent color, tint, brightness, and contrast levels
across all sources.

For system integration, the SVS 100 may be controlled through
RS- 232 control via Extron’s Windows®-based control program
or third-party control. Extron’s Simple Instruction Set™ is available
for calling up presets as well as all other functions of the SVS 100.
RS-422 control is also available.

■ Inputs – Accepts up to four NTSC or PAL video inputs. Two

inputs can be composite video or S-video, and two inputs are
composite video only. Each input also offers a loop-out for a
preview monitor.

■ Outputs – Three outputs provided simultaneously: two

composite video outputs on BNCs and one S-video output
on a 4-pin mini-DIN connector.

■ Seamless switching – A seamless “cut” reduces the amount of

noise caused by switching glitches. This noise reduction
reduces the load on a videoconference encoder, resulting in
better, transmitted video quality.

■ Digital effects – “Wipe,” “dissolve,” and “fade” effects are

provided to enhance the professional look of presentations.
“Wipe” effects may be hard “wipes” with clearly defined
edges or soft “wipes” with indistinct edges. 24 types of
transitions are available: left to right, right to left, top to
bottom, and so forth. Each effect provides a user-adjustable
duration ranging up to five seconds.

■ Picture controls – For color correction, the SVS 100 allows a

user to adjust the color, tint, brightness, and contrast of each
video input.

■ Blanking controls – Extron’s exclusive variable vertical

blanking adjustments allow a user to mask noise that
occasionally appears at the top and bottom of a processed
image or to crop unneeded portions of an image.

■ Audio switching – Features an internal, 4x1, balanced or

unbalanced stereo audio switcher on 3.5 mm conductor
terminals for selecting the desired audio of any video input.
Audio gain/attenuation is available.

■ User presets – Provides 128 user presets for saving color

adjustment settings per video input. Using presets, the SVS 100
ensures consistent color, tint, brightness, and contrast levels
across all sources.

■ Genlock – Features the ability to genlock to an external black

burst signal for use in broadcast or live environments that
require genlock.

■ RS-232/422 remote control – Extron’s Simple Instruction

Set™ is provided for RS-232 control via third-party control
or Extron’s Windows®-based control program. RS-422
control is also available.

■ Executive mode – Locks out picture controls, audio controls,

and genlock; all other functions remain active through
RS-232/422.

■ Power supply – Includes a worldwide, 100-240VAC,

50/60 Hz, auto-switchable internal power supply.

■ Rack-mountable – Housed in a 1U, one rack width, metal

enclosure.
