TZM 423 is a 4 inputs and 2 indipendent outputs matrix suited for routing VGA/XGA signals with combined audio. TZM 423 can manage YUV, RGBS or RGBHsVs signals as well. May be very useful when, driving a main output, it’s necessary to keep a second source under monitoring control or when it’s needed to drive 2 destinations by 2 different signals

Two independent buses 250 MHz Video bandwidth Integrated keyboard Remote selection by dry contacts Control by RS 232 Mute function for each bus Suitable for YUV/RGBS/RGBHsVs
