Tripp Lite's B132-100A-MR VGA with Audio over Cat5 Extender Receiver Unit is designed to work with Tripp Lite's B132-002A-2 and B132-004A-2 VGA with Audio over Cat5 Extender / Splitter Transmitter Units. Unlike the B132-100A Receiver Unit, which supports distances up to 305 m (1,000-ft.), the B132-100A-MR is a cost effective solution for distances up to 229 m (750-ft.) It extends a 1920 x 1080 video and audio signal up to 91 m (300-ft.) from the source, or a 1024 x 768 video and audio signal up to 229 m (750-ft.) Power is supplied via the included USB Micro-B cable, with no external power supply required. Connect the included Micro-B cables between the Receiver and a USB port on a computer, monitor, or USB wall charger, such as the Tripp Lite UAC-1B. It also features equalization and gain controls to adjust the video image. Audio connections are made with standard 3.5mm stereo cables (not included).
