Knox Video RSII - Manual (Page 6)

SECTION 1. GENERAL INFORMATION
1.1 INTRODUCTION
The KNOX RSII AUDIO/VIDEO ROUTING SWITCHER is a family of de-
vices, which accepts up to sixteen video sources and sixteen stereo audio sources.
The RSII connects any one of the sixteen inputs to one or more of the sixteen
outputs. The video signals may be switched independently or with the audio
signals.
The RSII family of switches consists of five basic models; Composite, Y/C,
YPbPr, RGB, SD SDI and HD SDI any of which can containbalanced, unbalanced
or no audio. Optional features include volume and tone control for the audio as
well as an Ethernet interface.
1.2 TECHNICAL DESCRIPTION
The RSII uses a single chip microprocessor with flash memory to drive a set
of monolithic digital latching crosspoint decoders.
Cross-point information is collected by the microprocessor from the optional
front panel controller (DFPC), from the RS232/RS422 inputs on the front or rear
panel, and from the optional ethernet I/O and distributed to the crosspoint decoders.
Audio and video may be routed together or separately.
The audio volume, tone, and balance may be adjusted if the VT option is
installed.
