1. Summarize
this chassis is used to match and connect the big screen LCD TV, it supports multi-system TV input signal ,
it can stored 128 TV programs at most, at the same time the highest resolution of this chassis can be up to
SXGA or appear R, G, B input signal of WXGA of 16:9 again, color appear again can support 24 bit, and it
can realize synchronous automatic check. It can support 1080P HD signal input at most, and includes two
rows CVBS signal, one row S terminal signal input, one row HDMI signal one row CVBS signal output.
Inbuilt 2x10W medium sound + 2x3W treble sound output, four rows two channels external audio signal
input, one row sound output. Support left and right sound balance, equalizer adjustment function.
Meanwhile, this chassis can support TV signal and digital display in HD signal at the same time, and there are
3A picture optimise, 3A demo.
