Connecting Audio Devices Using External Audio Devices for Playback You can connect a stereo system to amplify the instrument's sound by using the AUX OUT [L/L+R]/[R] jacks.

CAUTION When the instrument's sound is output to an external device, first turn on the power to the instrument, then to the external device. Reverse this order when you turn the power off. CAUTION 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.
