Used for 1 show, selling it as it has been in the office for the past few years. Kept in box so the unit is clean. Compact and lightweight, the Datavideo SE-500 4-Channel Analog SD Video Switcher features composite and S-Video inputs and outputs for switching live events at houses of worship, conventions, educational institutions, small studios, and other venues. The four inputs can accept composite signals via BNC connectors and S-Video via mini-DIN connectors. Two program output sections each have composite and S-Video options as well. For previewing all four video feeds, an onboard multiplexer sends all four outputs to a single monitor over a composite video feed. Using both the S-Video and composite outputs, a single high-quality component video stream can be sent to a compatible DVD or memory recorder. Digital sources can also be connected to the SE-500 using separately available converter boxes. Up to four channels of audio can be input via one set of stereo RCA connectors and two unbalanced 1/4" jacks. Using the onboard faders and audio meters, the sound can be mixed and properly balanced to fit your program. Balanced audio sources will require a separately available impedance switching device in order to ensure proper operation. Once set up, use the T-bar and illuminated selection buttons to switch and apply effects to your video signals. Some built-in transitions include dissolves, fades, and wipes. The SE-500 can also be controlled via RS-232 (DIN-15 connector) and MIDI. Essential effects such as picture-in-picture (PiP), color processing, and split-screen are also integrated into the SE-500. To keep things simple, all inputs are internally synced by a 4-channel 4:2:2 time base corrector (TBC), so no genlock or external syncing is required for achieving smooth transitions.
