| DSC 3G-3G A | 3G-SDI to 3G-SDI Scaler | 60-1453-01 |
The Extron DSC 3G‑3G A is a high performance 3G‑SDI scaler that converts between 3G‑SDI, HD‑SDI, and SDI resolutions and frame rates. It accepts, scales, and outputs SMPTE video resolutions from 480i and 576i up to 1080p/60 and 2K. The DSC 3G‑3G A features advanced Extron video signal processing with deinterlacing of signals up to 1080i, and Deep Color processing. The DSC 3G‑3G A also provides flexible audio capability with analog audio embedding, de‑embedding, and level adjustments. Dual SDI outputs, genlock, and an input loop‑through facilitate integration in demanding professional environments, while the compact enclosure simplifies installation. The DSC 3G‑3G A is ideal for applications with professional video systems, including video editing and production, rental and staging, medical imaging, and large‑scale presentations.
