What to do

• Using an AC outlet tester, test the AC outlet that the power stand is plugged into for

reversed or open (hot, neutral, and/or ground) contacts.

• If using an extension cord, make sure that the cord is also tested as above.

• Make sure you are using the included 4-wire B1 bass module cable.

• Make sure the B1 bass module cable is plugged into the Bass Module Out connector

and the cable plug is fully engaged in the connector.

• Try a different 4-wire cable.

• If available, try a different B1 bass module.

• Make sure you are using the B1 bass module 4-wire cable included with the B1 bass

module package.

• Make sure that the B1 bass module grille is facing forward toward the musicians and

audience.

• Make sure the L1 model II Cylindrical Radiator

seated in their connectors.

• Make sure connections are not bent or broken.

• Try cleaning the contacts on the loudspeaker top and bottom with electronic contact

spray cleaner.

• Make sure the Signal/Clip LED is not constantly red. If it is, lower the trim level.

• Try a different source or instrument.

• Try your source or instrument on another power stand.

• Unplug any B1 bass modules that may be connected to the power stand.

• The signal from the Bass - Line Out may be too high for the powered subwoofer; try

attenuating the signal using commercially available direct boxes or in-line pad devices.

• Try different connections to the third-party-powered subwoofer, such as balanced or

unbalanced cabling and/or a direct box.

• Check that the gain and input controls on the third-party-powered subwoofer are set

appropriately.

• If using a powered subwoofer with an adjustable crossover, set the crossover to 180Hz.

• Ensure that at least two B1 bass modules are directly connected to the Bass Module

Out connector on the power stand using a B1 bass module 4-wire cable.

• Check the gain settings on the third-party power amplifier. The volume level of the B1

bass modules powered by the power stand should be similar to the bass modules pow-

ered by the external amplifier.

• Orient the microphone so that it is not pointing directly at its respective L1 model II

Cylindrical Radiator

• Try a different microphone.

• Try a different position for the loudspeaker and/or vocalist on stage.

• Increase the distance from the loudspeaker to themicrophone.

• If using a vocal effects processor, make sure it is not contributing to the feedback

problem.
