4-Port Component Composite Video Switch + Digital S/PDIF Stereo Audio Switcher
This professional audio video switcher allows users to switch between multiple HD or standard video devices with digital/stereo audio support. This HD/SD video audio routing switch supports all HD and SD resolutions from 480i up to 1080p, making it ideal for use in studios, A/V receiver, home theater system, post-production facilities, educational use, or any other setting that requires a high-quality solution.

This HD video audio routing switch can also be used as straight composite video audio switch for all SD devices of NTSC or PAL system. 

Its seamless switching and distribution of all audio video signals allows you to connect more audio/video devices than regular TVs or receivers can accommodate and virtually eliminates cable hassles. No more connecting and reconnecting cables every time change sources and never run out of video/audio inputs on your HDTV/LCD TV set or projector again. 

This multi-purposed video audio switcher is perfect for cable boxes, satellite receivers, DVD players, video game consoles, video cameras, home theater systems, CD players and other digital audio/video components. 

High-Bandwidth Performance
This switch offers an extremely wide bandwidth capacity of 650 MHz. Moreover, video bandwidth is flat +/- 3db to beyond 650 MHz, ensuring the audio and video output from this HD/SD video audio routing switch maintain the same signal quality as the original inputs with no loss for long distance transmission.

4-Channel HD Component Video Switch
This unit provides flawless and seamless switching between up to four HDTV video inputs in component video format. This audio/video switch box supports all HD video formats at resolutions of 480i,480p,540i,540p,720p,1080i or 1080p. It is also a great way to expand your HDTV with more component video inputs.

Multi-Channel Composite Video Switch
When used as a straight composite video switcher, each one of the green or blue or red RCA jack on the input side can be used as an individual composite video input and will be routed through the same colored RCA jack on the output end for composite video output. 

So there will be 12 composite video inputs(4 green-colored + 4 blue-colored + 4 red-colored) with 3 corresponding color-matching composite video outputs (1 green- colored + 1 blue-colored + 1 red-colored). Great way to expand your HDTV or regular SDTV with more composite video inputs. 

[Note]: The output video type and output resolution of this switcher will be the same as the original input of component video or composite video type. This unit can not convert video format from one to another so it does not allow mix of inputs with different video types to be connected together to the same display unless the display is able to support multiple video types.

Digital S/PDIF And Stereo Audio Selector
You can easily  expand your existing audio receiver with more digital S/PDIF inputs and stereo audio inputs by adding this switch to the setup. This audio video routing switch supports both stereo L/R and digital S/PDIF audio inputs. Featured with 4 stereo L/R inputs and 4 digital coaxial S/PDIF audio. Audio input can be unbalanced or balanced stereo or digital PCM, all S/PDIF, DTS Digital Surround, and Dolby Digital 5.1 digital signals.

Multiple Operation Controls
This HD/SD video audio switcher may be controlled via the push buttons on the front panel or IR remote controller. RS-232 console port control is also a standard feature for this HD/SD audio switch to be operated from distant location or further integrated with other A/V systems.
