Kramer VS-402XL 4x2 Video & Stereo Audio Switcher with RS232

The Kramer Dual Output Series is a family of high performance two output, vertical interval matrix switchers for composite video and stereo audio signals. Two of 12 inputs can be routed to either or both outputs simultaneously. Since switching is performed during the vertical interval, glitch-free transitions are provided when sources share a common reference sync. The design features two independent sets of input select buttons, one set for each output, making it ideal for real-time applications requiring the ability to preview any input before committing it to a main output.The "02" family is also great for any application requiring a true two-output matrix. They are designed to be easily expandable for larger switching requirements. All three versions include RS-232 control capability.
