    VP-23
Compatible with HDTV component video signals when used with a 
breakout cable such as the Kramer C-GM/3RVF. 

The 
Kramer VP-23 
is a 
high quality Presentation Switcher designed for a wide variety of presentation 
and multimedia applications. It combines the functions of a 4 x 1 switcher for 
composite video and audio, a 4 x 1 switcher for s-Video and audio, and a 4 x 1 
switcher for VGA-type signals with audio, all in a single high performance unit. 
The VP-23 
is designed to 
become a one-box solution for systems, which would otherwise require several 
separate products. Each section can be controlled independently from the others. 
The VP-23 
can be 
controlled by front panel buttons or by RS-232 serial commands transmitted by a 
touch screen system, personal computer, or other serial controller. The 
VP-23 
has an 
additional audio switching section which routes one of the pre-selected audio 
inputs from the other switching sections to a separate output. This switching 
section can insert an additional microphone channel - either by switching, 
mixing or talk-over. Front-panel controls allow adjustment of VGA/XGA output 
level and EQ., Master audio output level and Microphone level.
