4x4 HDMI Seamless Matrix - Crossbow™ By Salt

4x4 HDMI Seamless Matrix with 2x2 Video Wall Option

"Website is sweet - got my order in 2 business days."


Easily route 4 HDMI sources (e.g. your Blu-Ray player, streaming box, satellite receiver, and game system) to 4 HD displays in any combination using the Crossbow Seamless 4x4 HDMI Matrix by Sewell. Whether you're setting up a mission-critical install for a commercial setting, creating a 2x2 video wall, or if you're just wanting to route HDMI to multiple rooms in your house, the Crossbow 4x4 gets the job done with instantaneous (aka 'seamless') switching.

Instant 4x4 Matrix Switching

A lot of data is transferred in-between switching before an HDMI signal can successfully make it up on the screen from a new video source. The TV and the video source have to do what is called an EDID handshake where they negotiate the details of how the video image will be displayed. Resolution, refresh rate capabilities, and color specs are some of the things that are communicated between devices.

HDMI Video Wall

2x2 Video Wall Processor Option

In addition to being a 4x4 seamless matrix, The Crossbow 4x4 can optionally function as a 2x2 video wall controller. So if you have four large screens that you'd like to use to make up one giant video image, the Crossbow 4x4 is the cost-effective answer.

Multiple control options

The Crossbow comes with an IR remote control but to be honest it kind of sucks. The real power of IR can be unlocked with a "Logitech Harmony Remote". With the ease of Logitech and the tech of Sewell, you have just entered into the next level of entertainment.

RS-232 and IP Control

Whether you are doing rudimentary HDMI matrix routing or if you're wanting to switch to 2x2 video wall mode, doing everything on a computer screen makes this easy for even a beginner to take full control of all of the Crossbow's features.

  1. 4x4 Matrix mode - Switch Control
  2. 2x2 Video Wall mode control
  3. Toggle on/off HDMI Video Outputs
  4. Push changes live to Crossbow
RS-232 control

2x2 Video Wall Bezel (Border) Control

When setting up a 2x2 video wall, you'll want to have control over how well each of the 4 images fit together since almost all HDTVs and monitors have a bezel. The bezel is the border (usually plastic or metal) that surrounds the viewing area of your HDTV or monitor. There are many different-sized bezels out there and since there isn't a 'one-size-fits-all' bezel, the Crossbow 2x2 video wall option gives you the ability to adjust the number of pixels you want to include on each screen to ensure that the 2x2 video wall is giving the viewer a true 2x2 fused experience.

HDMI Matrix IP Control

Crossbow 4x4 takes all the time out of that handshake by doing it in the background while you watch one of the sources. The powerful processor inside processes multiple signals simultaneously and stores all of the EDID info making switching take about 100ms.

A Need for Zero Delay Switching

Pros: Very easy to setup. Works as advertised and is truly seamless.

Cons: Only wish the software was Mac compatible. You can workaround with Wine or other similar products but still a 'pita'. I was able to use the IP protocol through my home network but the system is installed where there is no network available.

Other: Overview -- Our club has monthly meetings where we hold demonstrations in woodturning. We record live and switch between 3 cameras. After the demonstration the recording is downloaded, edited and recorded to DVD for future viewing. We needed to eliminate a 3.5 second delay encountered when switching between the 3 cameras. Our system is HDMI. We output to 2 large 58" TV's for the viewers and 1 - 18" monitor for the demonstrator. After countless hours researching "Seamless" switching units I purchased this unit. The first unit arrived but I was unable to view any of the camera outputs. After contacting Support and a troubleshooting conversation it was determined to send another unit. Support sent the unit within 2 days. A quick setup at my home, fingers crossed, power on and SUCCESS! We now had our 3 camera output "instantaneous switching." I grabbed the unit and cameras and headed to our club to setup the system. Our monthly meeting was held on Tuesday. A resounding SUCCESS. The recording was downloaded and it also was successful with the seamless switching producing NO errors. I have passed along my review and assessment to other clubs with similar needs and equipment. I highly recommend this unit for those with similar needs.
