INSTALLATION
Power
After making the audio connections, check the voltage switch on the back of the SUB105 to make sure it is set to the correct voltage for your area. Insert one end of the supplied power cable into the IEC receptacle next to the voltage switch and the other end into a live power receptacle.
Remove the grille from the front of the SUB105 to access the control panel. Slide the power switch to the Auto setting to place the SUB105 in standby mode or the On setting to place it in full on mode.
Adjustments
Crossover frequency
Set the crossover frequency to match the
•For main speakers with a full frequency range, set the crossover between 50 and 80 Hz.
•For main speakers with limited bass extension, set the crossover between 80 and 100 Hz.
•For main speakers that reproduce only midrange and high frequencies, set the crossover between 100 and 200 Hz.
Your receiver or processor may have a bass management feature with settings for large, medium, and small main speakers. Refer to your equipment manual to determine the appropriate crossover setting if you use this feature.
The goal is to set the crossover frequency at the point where the subwoofer reproduces the low frequencies

not reproduced by the main speakers, with very little overlap and no gaps in the overall response of the system. To make this adjustment precisely, you can use a calibration CD or DVD and a
Volume
Start with the volume set at minimum, raising it gradu- ally until output from the SUB105 sounds about the same volume as output from the main speakers. Again, you can use a
Phase
Depending on the location of the SUB105, its output at certain frequencies may be out of phase with the output of the main speakers. This is especially true when the subwoofer and main speakers are very different distances from the listeners.
To compensate for this, try setting the phase switch at both positions. You may find that one position provides smoother bass response than the other.
