MX2456RM

6-IN, 1-OUT VIDEO/AUDIO SWITCHER

The 

MX2456 RM 

is a video and audio switcher with 

six video inputs that can be connected to a single 
video output and has six balanced-stereo audio 
inputs. These six balanced-stereo audio inputs can 
be connected to a singe balanced-stereo audio 
output.  This allows for the non-simultaneous 
connection of up six computers or six video and six 
audio sources to a monitor or projector and to any 
audio system. 

The 

MX2456RM

can pass a variety of video signal 

types: RGBHV, RGBS, RGsB, Component Video 
(Y, R-Y, B-Y), S-Video and Composite Video. The 

MX2456RM

is controllable by using its built-in front 

panel or through RS-232. 

Each of the video inputs is ground loop isolated and 
can  promote individual equalization of video gain 
according to different cable lengths. 

The 

MX2456RM

has a video bandwidth of 300 MHz 

and an audio bandwidth of 40 kHz.
