The internal patch bay features your choice of banana jack or 1/8" mono jacks and includes in/out jacks and knobs to attenuate the amount of resistance between patch points. Patching combinations adds a variety of chaotic glitches, stutters, and hue alterations to any composite video source. Features two RCA in and output channels. Most settings will require a time base correction unit, if using a modern digital television or projector. Will include four patch cables. Please Note: The patchbay is for internal use only, external voltages from other gear will very likely damage the circuits, and is not recommended. Stills are processed footage from Preston Spurlock's fabulous 'Math Rock Countdown VHS'!
