4.2 Damping Factor in cable
Turbosound recommends that for large scale PA use the total system damping factor should be 15 or greater. Longer
cables will reduce the overall damping factor of the system. In order to keep the damping factor over 15 it will be
necessary to increase the impedance of the load to keep the damping factor. Therefore for long runs Turbosound
recommends no more than two enclosures per amplifier. Turbosound recommends using 4mm
2
cable as standard.
