Switchblade LPU2 – 2U vMix Replay System with 4IN/1OUT SDI and Replay Controller

Switchblade LPU2 vMix Replay Server with RP400 Control Surface

An Affordable 4-Channel Instant Replay and Slow-Motion System

Multi-channel instant replay systems in sports are typically limited to professional and collegiate organizations due to their high costs. However, with the advanced capabilities of vMix Replay integrated into vMix Pro software, this financial barrier is effectively removed.

Nonetheless, operating a multi-camera replay system efficiently necessitates appropriate hardware. Switchblade Systems leverages extensive experience in designing broadcast-ready production systems, and with the LPU2 vMix Replay Server, concerns regarding compatibility and reliability are largely alleviated. The LPU2, paired with the RP400 replay controller, empowers sports broadcasters at all levels, from youth leagues to high schools, colleges, and beyond, to deliver eye-catching replays.

More About the Switchblade LPU2

The Switchblade LPU2 is a compact, rackmount video switcher and replay system based on vMix Pro live production software. The LPU2 packs all the essential features and I/O for running multi-camera replays from any location.

Today’s live events rely increasingly on a combination of traditional physical inputs like SDI and IP sources, including NDI and SRT. The LPU2 handles both with equal ease, packing four (4) 3G-SDI inputs, a separate SDI/HDMI output, and vMix’s native support for NDI, NDI|HX, SRT, RTMP, and RTSP network video sources.

The compact, short-depth 2U chassis makes this tiny rack-mountable platform ideal for smaller studio rack spaces and transportable flypacks. Even setups without rack cabinets will find its diminutive size small enough to use on top of a desk.
