The MX2224AT is a 4-In 1-Out RGBHV switcher controllable using its built-in front panel or via RS-232. The MX2224AT utilizes relays internally for each component channel, enabling it to pass a wide variety of signal types, including RGBS, RGsB, Component Video (Y, R-Y, B-Y), S-video (Y/C), Composite Video, Mono or Stereo Audio, and even RS-232.

The MX2224AT can also be used bi-directionally; a signal can be routed "backwards" through the switcher to allow a single source to be connected to as many as four displays.

If desired, the MX2224AT can be operated in a Sync Delay switching mode to eliminate the "glitch" typically associated with switching between high resolution sources. This delay is factory preset at 2.5 seconds and can only be used when switching between RGBHV and RGBS format signals.

The MX2224AT offers Step Switching. Activated by a single button on the front panel, Step Switching allows the user to cycle through the inputs sequentially, making the MX2224AT perfect for monitoring applications. The MX2224AT also offers a Video Off feature. This disconnects the video portion of the selected signal but continues to feed sync so that the monitor or projector does not go into a "no display" mode.

Multiple MX2224AT units may be looped together to create a larger switcher with more inputs. By connecting together two pins on the control port of each switcher used, the multiple switchers will act as a single switcher when controlled from the front panel.

The MX2224AT delivers an extremely high bandwidth of 400 MHz, allowing it to remain transparent to even very high resolution signals. Its compact design requires only 1U of rack space and its great variety of features make it perfect for rental or permanent installation applications.

The MX2224AT may be rack-mounted using hardware supplied with the unit.
