Gefen EXT-WHDMI receiver, back panel

An HDMI output and an analog-audio output, plus a port for an IR blaster, comprise the receiver's back panel. Stereo audio on the transmitter can't be piped into the HDMI output on the receiver; you'll need to connect the audio output separately. But the provision of an analog-audio connection allows you to connect both component-video and legacy DVI devices that require a separate audio connection.
