Why It Helps

This is the kind of switcher that makes sense when your show is a mix of cameras, laptops, and IP sources, and you still want predictable signal flow. HDMI 2.0 and 12G-SDI let you bring in higher-resolution sources, while USB-C capture, USB-C record, and NDI give you practical ways to feed a computer workflow, record to media, or move video around a network without redesigning the whole system.

System Characteristics

Audio timing control: line-in delay is supported up to 8 frames, which helps when you are chasing lip sync across mixed sources
USB audio behavior: USB audio is linear PCM 16-bit/48 kHz, 2-channel, which is typical for computer capture paths
HDMI audio behavior: HDMI audio is linear PCM 24-bit/48 kHz, 2-channel
Latency expectation: video latency is rated under 4 frames, so it stays usable for live switching and operator monitoring
Deployment range: rated 0℃ to 45℃ and 10% to 85% RH, with a 1.48 kg chassis that is easy to rack-shelf or table-mount
