Description
Key Digital's KD-MS4x4G is an HDMI matrix switcher that performs independent audio switching, balanced and unbalanced audio, and audio de-embedding of analog pulse-code modulation (PCM). This matrix switcher supports 18Gbps of signal bandwidth. Using HDCP 2.2 for signal and routing distribution, the KD-MS4x4G ensures that your signals go to authorized devices only. This matrix switcher distributes 4 HDMI source signals to 4 displays of your choosing. Both analog and digital audio outputs are controlled individually. This ensures that HDMI outputs can be controlled independently, allowing you to employ them for other uses within your professional AV system.
The KD-MS4x4G ships complete with a 12V DC power supply, rack ears for mounting, a remote control, and a total of five 6-pin terminal blocks. Other key features of the KD-MS4x4G include the following:
