Video to PC/HDTV Switching Scaler w/Audio

 

1. Introduction 

 

1.1 General 

The AC138A is a multiple format switching video scaler. It has 4 
different types of video inputs and a scaled output that can be switched 
to any of the inputs. 

Inputs are: Composite Video (NTSC or PAL), S-video (NTSC or 
PAL), Component Video (SD and HD from 480p to 1080i), and a PC 
(from VGA (640x480) to UXGA (1600x1200)). Audio inputs are line 
level 3.5mm stereo jacks, with adjustable volume control. 

The output format and resolution can be specified by the user as either 
PC (VGA (640x480) to SXGA (1280x1024)) or Component Video 
(YPbPr from 480p to 1080i - a VGA to 3 RCA adaptor cable is 
included).  The user can set the output to the optimal sweet-spot of 
your display and let the AC138A handle and convert various kinds of 
video inputs for your LCD.  

The Video Scaler can be controlled in many ways including: front 
panel lighted pushbuttons (with On-Screen Display menus), using the 
included IR remote control, or RS-232 Serial interface. The controls 
include: input switching, setting the output resolution, picture 
adjustment (tint, color, brightness, contrast, and sharpness), aspect ratio 
(Standard, 16:9 or 4:3), digital noise reduction, 3D comb filter ON/Off, 
volume control and many other advanced features.  

The AC138A is ideal for use with in boardrooms, classrooms, digital 
signage, and high end home-theatre applications. Its output can be set 
for any LCD projector, PC LCD monitor, plasma, or HDTV displays. 

The unit is shipped with all the required cables and adapters, IR 
remote, and also Windows® PC based RS-232 control software.
