NOTICE
When the Clavinova's AUX OUT jacks are connected to an external audio system, first turn on
the power to the Clavinova, then to the external audio system. Reverse this order when you turn
the power off.
The sound condition output from the internal speakers and the headphones
changes automatically to the appropriate settings depending on how the external
device is connected to the AUX OUT jacks (see chart below).

NOTE
Use cables and plugs with no
resistance.
NOTE
Do not route the output from the
[AUX OUT] jacks to the [AUX IN]
jacks. If you make this
connection, the signal input at the
[AUX IN] jacks is output from the
[AUX OUT] jacks. These
connections could result in a
feedback loop that will make
normal performance impossible,
and may even damage both
pieces of equipment.
NOTE
If you want to take a mono signal
via the AUX OUT jack, connect a
cable to the [L/L+R] jack.
