Extron’s VSC 75 high resolution computer-to-video scan converter uses

Extron’s exclusive advanced digital processing to convert high-

resolution computer-video images from as high as 1280 x 1024 @ 60 Hz

down to NTSC or PAL video for use in videoconferencing, video

recording, or viewing applications. Videoconferencing users at the near

end may integrate computer sources into their conferences by scan

converting higher-resolution signals down to composite video or

S-video for CODEC input. The VSC 75 utilizes 720 pixels per line

sampling to capture high-resolution information, ensuring sharp image

output. An internal test pattern generator outputs color bar patterns

for setting up color adjustments.

■ Autoscanning – Recognizes and converts computer images from

560 x 384 up to 1280 x 1024 @ 60 Hz.

■ VGA/Mac input – 15-pin D and HD connectors available for easy

connection to any Macintosh or IBM-compatible computer. The

passive local monitor output allows the user to display images on

the local monitor as video plays simultaneously on the display

device.

■ Outputs – Outputs NTSC or PAL video as composite video and

S-video outputs.

■ Memory locations– Includes 30 factory/user memory presets for

horizontal & vertical sizing, vertical filter, and horizontal &

vertical centering settings with autosave and auto-recall.

■ Internal test pattern generator – Outputs color bar patterns for

setting up color adjustments.

■ Picture controls – Freeze, horizontal & vertical sizing, zoom, and

horizontal & vertical centering/pan controls available.

■ Vertical filtering – Two user-selectable levels of vertical filtering

reduce flicker.

■ Simple Instruction Set (SIS™) – Extron’s SIS provided for

RS-232 control via Extron’s Windows®-based control program or

third-party control.

■ Rack-mountable – The rack-mountable VSC 75 is housed in a

1U high, 1/2 rack width enclosure.

■ Internal power supply – 100-240VAC, 50/60 Hz, auto-switchable

internal power supply included.

■ Cables included – Includes a VGA/Mac input adapter cable.
