SERVICING
GENERAL INFORMATION
Your Iconyx steerable column array contains no user-serviceable parts and all service should be referred to qualified serv-
ice personnel.
Great care was taken in its design, however, to allow it to be serviced in the field without being removed from its mounting
position. The tranducers can be replaced from the front of the column by removing the grille to expose the transducers
and their mounting screws.
The 8-channel digital amplifier/DSP and associated power supply that is the heart of each 8-channel module is one single
assembly (see below) that can easily be taken out and replaced by removing the module’s side panels.
TROUBLE SHOOTING HINTS
Hum
The most common sources of system hum are the program source or an improper or poor ground on the audio signal line.
Check the program souce 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 system from adjacent noise
sources, such as fluorescent lights, and close proximity of the audio signal lines to lines radiating noise. Carefully review all
the audio connections and turn off all the lights and any other suspected noise sources.
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 to tell which one it is. The digital steering also reduces the drive to some of the tranducers making it diffi-
cult to determine if a certain transducer has failed or is just being driven at a much lower level than other transducers.
