INTRODUCTION 

With only one cost effective CAT.X cable, the AV-GM03W3-S1 lets you extend Composite signals up 
to 330m (1,000ft). The devices are composed of a transmitter and a receiver. The transmitter is 
installed near the signal source, and the receiver AV-GM03W3-S1-RX is placed near the desired 
display. With built-in EQ and GAIN control, the transmission path can be adjusted to adapt the cable 
quality and video bandwidth. Furthermore, the Composite RGB delay control [de-skew] function 
provides the compensation among R, G, B signals due to long transmission or through normal LAN 
cable. Analog stereo audio signals can be sent along with high quality Composite signal over long 
distance LAN cable.
