10. Operating�the�Speakers
• Switch off all equipment and turn down all level controls of the mixing console and the power
amplifiers.
• Wire your SONA 5 systems according to the instructions in this manual.
• 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 connec-
tions.
• Successively turn up the individual power amplifier channels and send a signal with low vol-
ume to the system. Check to see if the desired signals are applied to the intended speakers and
make sure there is no interference.
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 possi-
ble. 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.
