SUSPENSION MOUNTING (FLYING)
The end caps of the column array are attached to the main frame with four metric M6 machine screws. Removing these screws and replac-

TROUBLE SHOOTING HINTS
HUM
The most common sources of system hum are the program source or an improper or poor ground on an audio signal line. Check the pro-
gram source to make sure the hum isn’t originating there. Carefully check all the audio connections to make sure they are properly made.
NOISE
Most noise problems are the result of improper grounding or of noise being induced into the audio signal line from adjacent noise sources,

and turn off all the lights and any other suspected noise sources to identify the source of the interference.
SUSPECTED TRANSDUCER FAILURE
Defective transducers are hard to locate in steerable column arrays because the transducers are so close together. If one is bad, it’s hard

transducer has failed or is just being driven at a much lower level than other transducers. No movement of the cone of a transducer is not
positive proof that the transducer is bad. It could be that beam steering is limiting the drive to the transducer or restricting its use to a nar-
row frequency band.
Because of this, in IC Live arrays Preset 00 is set to send an equal signal to all transducers. To check for a defective transducer, select
