When your receiver or amplifier is off, or is not sending program material to the sub- woofer, the subwoofer will be in Standby mode and the LED indicator on the top of the subwoofer will turn amber. When the subwoofer senses an audio signal, it will auto- matically turn itself on and the LED indicator will turn blue. If the subwoofer does not sense a signal after approximately 20 minutes, it will automatically go into Standby mode.

The trigger signal must be between 3 and 30 volts, although it may be an AC or DC signal, and an AC signal may be 50Hz or 60Hz.
If you’ll be away from home for an extended period of time, or if the subwoofer will not be used, switch the Master Power Switch ‚ to the OFF position.

Additional Bass Adjustments
In addition to the volume adjustments described previously, the
™that can be used to adjust the bass response to suit your listening environment or taste.
In most situations, the Phase Switch ∞ should be left in the NORMAL position. If you suspect that the subwoofer is playing out of phase with the other speakers, which would tend to diminish bass response, try placing this switch in the REVERSE position. There is no harm in experimenting, and you may return the switch to the NORMAL position at any time. If you rearrange your room and reposition the speakers, it would be a good idea to check whether they are in phase by flipping this switch.
The High-Cut (Low-Pass) Filter Switch
™limits the frequencies of the audio signal inputted to the subwoofer to the low fre- quencies that the subwoofer reproduces best. This allows the subwoofer to perform more efficiently, and with superior bass reproduction, minimizing distortion that might occur if the subwoofer attempted to repro- duce higher frequencies. This switch should be left in the ON position, except:
1.When the SUB Input § is being used, in which case it has no effect, or
2.When the
¶ are being used with a crossover or filter aboard the receiver or processor.
In these two circumstances, place the switch in the OFF position.
