1. Volume/Power - This knob controls the volume as well as the power status of the subwoofer. The Sub6/10 subwoofers incorporate an AutoTurn-On/Off Circuit. Turn the volume knob completely counterclockwise to turn the subwoofer OFF. 2. LED - Red/Green. This LED indicates the Mode status that the subwoofer is in. The LED will light Green when the Volume knob is turned clockwise to ON. The LED will light Red when the Volume knob is turned off (the knob turned fully clockwise) or the receiver/amplifier has been turned off for five minutes. The subwoofer will turn on when your receiver/amplifier begins playing again. 3. Crossover Frequency - The crossover frequency knob determines the highest frequency your subwoofer will reproduce. It allows a seamless transition from the subwoofer to the satellite speakers. 4. Phase - The phase switch is used to adjust the relative polarity of the subwoofer. 5. 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, they are driven the full range of frequencies as generated by the music source (receiver, amplifier, etc.) 6. 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. 7. Mono/Stereo - This setting of this switch affects the subwoofer when using the Low Level Input only. If you are using a dual (stereo) RCA cable, set the switch to STEREO; if using a single (mono) RCA cable, plug into the (R) Input Jack and set the switch to MONO. 8. Low/High - The setting of this switch depends on which method of Input Connection you will be using. When using the Low Level Input (RCA Connectors), set the switch to LOW; when using the High Level Input (Speaker Connectors), set the switch to HIGH. 9. Fuse - Use only same type of fuses. Use a 3.15A 250V fuse for the 120 volt American version and use a 4A 250V fuse for the 230 volt European version.
