Both can take from the six digital inputs: three HDBaseT and three HDMI signals; while the first also includes analog inputs - for two computer graphics signals, two composite video and two analog TP inputs. Analog, digital and embedded audio are supported, and the unit also includes a microphone input and rich DSP features.
