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-

ing them with eye bolts provides up to four attachment points for flying. We recommend using all four. If only 2 are used the column will not

hang straight. It will either tilt up or down.

TRIPOD STAND MOUNTING

If you plan to use your ICONYX IC8-R-II or IC16-R-II mounted on a heavy-duty tripod stand using our ICTRIPODKITR, be aware that you

must mount the top mounting bracket to the array before attaching the tripod socket to the bracket. Otherwise you will not have access to

all the bracket mounting screws.

SERVICING

GENERAL INFORMATION

Your Iconyx steerable column array contains no user-serviceable parts and all service should be referred to qualified service 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

transducers 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 are the heart of each 8-channel module are one single assembly

that can easily be taken out and replaced from the rear.

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,

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 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

to tell which one it is. The digital steering also reduces the drive to some of the transducers making it difficult to determine if a certain

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-R-II arrays Preset 00 is set to send an equal signal to all transducers. To check for a defective transducer, select

Preset 00, remove the grille from the module(s) and use your fingertips to feel for cone vibrations while music is being played through the

system.
