speakers to hear audio from:
The -
ANT

A game or camcorder connected to the conve- -
nience input (
INPUT 3
).

setup sequence is:
Connect the HDMI cable.1.

If you connect to HDMI after performing
NetCommand setup for the A/V receiver, the
NetCommand setup will be lost.

A/V receiver may not be passed over the HDMI cable
to the TV speakers. In these cases you must use the
A/V receiver speakers to hear audio.
Multiple video inputs through a single HDMI cable. You can
connect multiple video devices to an A/V receiver that has
