(one on the front panel and the other on the rear panel), one composite
video input (on the rear panel) with an unbalanced stereo audio signal, and
a dynamic or condenser microphone input
•Includes an RGBHV output, a composite video output and two identical
audio outputs
•Includes bidirectional RS-232 and IR out for controlling the display device
