This section describes the 

OMX-SW6x6. 

 

About the OMX-SW6x6 

 

The 

OMX-SW6x6 

is a broadcast quality high performance matrix switcher for composite video and 

unbalanced stereo audio signals. Switching during the vertical interval ensures glitch-free switching 

with  genlocked  sources.  It  is  a  true  matrix,  letting  you  route  any  input  to  any  or  all  outputs 

simultaneously.  

 

The 

OMX-SW6x6 

can  switch  stereo  audio  signals  in  "audio-follow-video"  mode  or  separately 

(breakaway). Also, the TAKE button lets you place multiple switches in a queue, and then activate 

them with one touch of this button or a single serial command. The 

OMX-SW6x6 

has manual, RS-

232  and  RS-485  controls.  Six  preset  memory  locations  are  provided  for  quick  access  to  common 

configurations,  and  the  non-volatile  memory  "remembers"  the  last  setting  prior  to  being  powered-

down. The machine has an external Sync/Genlock input as well, and may be programmed to switch 

according to the timing of either this input or of source number 1. 

 

It is dependable, rugged, and fits in two vertical spaces of a standard 19” rack. Video bandwidth of 

200MHz ensures that it remains transparent even in the most critical applications.

OMX-SW6x6. 

Figure 2 and Table 2 define
