1. Output Level - The Output Level adjustment determines volume level strength. 2. Crossover Frequency - The Crossover Frequency adjustment determines the highest frequency the ARC SUB will reproduce. It allows a seamless transition from the subwoofer to the satellite speakers. 3. On (LED) - This LED will light green when the unit is plugged in and is receiving signal. When in standby mode the LED is red.
4. Low Level Input - These left and right Line Level Inputs are normally used when the receiver/processor has line-level �pre-amp out � or �subwoofer out� jacks. 5. Fuse - Use only a slow-blo 1.0A 250V GMC fuse. 6. High Level Inputs - These High Level Inputs are for receivers that do not have line-level �pre-amp out� or �subwoofer out� jacks. When a pair of main or satellite speakers are attached to the OUTPUT terminals, frequencies below 180 Hz are attenuated by the high-pass filter.
