connectors to your amplifier or powered speakers. See image call-out on Page 4, “Stereo In”.
The stereo output is a mix of program audio (audio extracted from the selected HDMI input)
and stereo audio line input (3.5mm jack). The default mix and level should be adequate for most
installations. However, gain and volume level adjustments are available through the RS-232
interface.
