1. Introduction
CHMX-24 is a high performance HDMI Matrix with remote control.
It offers you maximum convenience in HDMI signal distribution when you have
multiple HDMI sources and displays to connect together.
Each of the two HDMI sources can be directed to any one of the four outputs,
so four displays can show 4 identical or 2 pairs of different sources at the same time.
CHMX-24 provides a maximum of 8 possible connection scenarios between
sources and displays. When HDMI signal progresses through CHMX-24, it is re-timed,
level compensated, phase error corrected, and data jitter eliminated, so the
output is a regenerated brand new HDMI signal that can run for another 25 meters
and can be cascaded.
2. Features
1. HDMI 1.2, HDCP 1.1 and DVI 1.0 compliant.
2. HDMI input is compensated, clock / phase adjusted, and jitter eliminated so
the output is a well tuned standard HDMI signal.
3. Input source LED indicators on each output select.
4. Ideal for home theater integration, conference room and retail stores.
5. Compatible with all HDMI sources and displays.
6. Supports high resolution input/output:
PC: VGA, SVGA, XGA, SXGA and UXGA (1600X1200) &
HDTV: 480i, 576i, 480p, 576p, 1080i, and 1080p
7. RS-232 control.
8. IR remote control.
