Introduction
AT-HDMI-24M 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. AT-HDMI-24M
provides a maximum of 8 possible connection scenarios between sources and displays. When
HDMI™ signal progresses through AT-HDMI-24M, 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.
Features
1. HDMI™ version 1.3, 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.
