Present with complete confidence at tradeshows, conferences or other larger venues. A high brightness level of 4500 lumens & a 2000:1 contrast level ensure that your presentation shows crisp & clear even in large meeting rooms & conference halls. This mobile projector is built for savings. The st&-by (low) mode consumes less than 1 watt, so you use less energy. Structurally semi-sealed, the XD600U eliminates the need for an intake filter under normal conditions & lowers cost. Increased estimated lamp life means lower maintenance & reduced operating cost. The XD600U mobile projector offers remarkably silent 29 decibel operation in low mode. A specially calibrated lens allows projection distance that is 1.5 times greater than standard. Images are brilliant & clear whether projected a short or long distance (from 68 inches to 102 inches using a 60-inch screen). Amplify your voice in real time with the optional wireless microphone. The built-in 10 watt speaker & audio mixer eliminate the need for an external speaker.
