AXING UIM 1-00 Universal Input Modulator HDMI CVBS YPbPr to RF DVB-T/C

With a MER exceeding 35 dB and support for both DVB-T (COFDM) and DVB-C (QAM), the AXING UIM 1-00 delivers professional-grade signal conversion for any distribution network. This compact metal modulator accepts HDMI, CVBS, or YPbPr sources and outputs a robust RF signal across 47–862 MHz, making it a cornerstone for modern hospitality, education, and healthcare AV systems.

Overview

The UIM 1-00 is engineered for seamless integration into existing coaxial infrastructures. It automatically detects the active input, encodes video in H.264 up to 1080p, and modulates the stream into a selectable DVB-T or DVB-C channel. Configuration is straightforward via a USB connection, and the adjustable output level (70–100 dBµV) ensures optimal signal strength for any cable length or splitter configuration.

What stands out

• Dual modulation standard: DVB-T (COFDM) and DVB-C (QAM) with selectable constellations and bandwidths (6/7/8 MHz)
• High-quality encoding: H.264 video, MPEG1 Layer II/AAC audio, supporting up to 1080p resolution
