克萊默KRAMER-4K30 UHD DVI (HDCP)ProScale演示矩陣切換器/雙倍線器帶切換特技-VP-772

　　VP?772是一款8輸入高性能UHD（4K）雙倍線器，帶各種過渡特技，可用于舞臺租賃，現場直播等系統。它的接口為DVI?U輸入（支持模擬，DVI和HDMI信號）和平衡立體聲音頻信號。該設備將選擇的視頻音頻信號經過倍線處理之后輸出到兩個獨立的DVI?I輸出（主輸出和預覽輸出），并帶有平衡立體聲音頻輸出。

　　PixPerfect? Scaling Technology — Kramer’s extremely high performance, state–of–the–art scaling technology with extensive high–quality pull–down and de–interlacing algorithms, and full up–and down–scaling of the video inputs.

　　K–IIT XL? Picture–in–Picture Image Insertion Technology — Ultra–stable picture–in–picture, picture–and–picture, and split screen capability. Any video source can be inserted into or positioned next to any other video source with full window positioning and sizing controls.
