• Make sure a signal source is connected and producing sound

• Make sure the white power ON LED is illuminated on the front of the speaker.

• Confirm the included power supply is connected and the power switch is set to the ON position.

• Make sure the volume control is not set to the full counter clockwise position

• If the C2P Extension Speaker does not produce sound, make sure the extension speaker wire 1/4" plug is connected to the EXTENSION SPEAKER 1/4" output connector. Make sure the bare-wire end of the cable is connected to the extension speaker wire terminals.

• If the system sounds as if it lacks low frequency (bass) performance, confirm the bare wire is connected so the RED wire is connected to the RED speaker wire terminal, and the other wire is connected to the BLACK speaker wire terminal. If the above measures do not correct the problem, please contact JBL Professional NOTE: If the red LED on the front of the speaker flashes due to continuous over-driving of the system, overload-protection may be activated and no sound will be heard.
