When the subwoofer is used as a subwoofer extension, the level control is disabled and the MAIN display field is turned off. SUB Level control – Adjusts the volume balance between the subwoofer and the column speaker. When the sub- woofer is used as a subwoofer extension, the level control is disabled and the SUB display field is turned off. System Status Display - Provides visual feedback on oper- ating conditions. l PROTECT – Indicates that the system is overloaded or overheating. The amplifiers are muted automatically. Once normal operating conditions are restored, the unit returns to standard operation after a few minutes. GENERAL QUICK START GUIDE 4 l LIMIT – Indicates that the speaker system is operating near its upper limit. Brief illumination is not critical. To protect the system, excessive signal levels are smoothly reduced by the integrated limiter. If the lim- iter LED remains lit for longer or permanently, reduce the volume level. l SIGNAL – Indicates that the device is receiving an audio signal. The signal is detected before the main level con- trol. l POWER – Indicates that the device is properly connec- ted to the mains and switched on. l FOLLOW – Indicates that the columns have been de- tached from the system and the subwoofer is being used as a subwoofer extension. CARDIOID OFF Icon – Illustrates the correct MAIN and FOLLOW orientation when the cardioid preset is disabled.
