First-time Use
•
Switch off all equipment and turn down all level controls of the mixing console and the
power amplifiers.
•
Wire the SONA 6 systems.
•
Switch on the mixing console first, then the controller and the power amplifier. Always
use the before mentioned switching order. Otherwise switching noises may damage the
sound system.
•
If there is interference, turn off all appliances in the reverse order and check all cable
connections.
•
Successively turn up the individual power amplifier channels and send a signal with low
volume to the system. Check whether the audio is properly routed to the appropriate
speakers. Make sure no noise is heard through those speakers.
With controller: The SIGNAL LEDs of the CD 44 Controller will light up if the output
level is higher than -45 dB. Your system should now be ready for operation.
•
Turning down the input level controls may not always prevent distortions in the input
section of the power amplifier, especially if this section has a relatively low headroom.
A clipping signal may not be displayed by the clipping indicator then! To prevent signal
interruptions or damages to the speakers, turn the level controls of the power amplifier
to the maximum position, if possible. Set the output level of the mixing console or the
controller to a level that doesn't overload the power amplifiers or decrease the limiter
threshold of the controller.
•
When turning off the system, the input controls for the power amplifiers should be
turned down first followed by the power switches of the amplifiers. After that, the
other appliances can be turned off.
