about the same frequency you have set the High Pass Filter. For example, if the High Pass Filter sends only signals above 75Hz to your main speakers, begin with the Low Pass Filter set at 75Hz. See the “Fine Tuning” section for further adjustment guidelines.
If you are using Connection Method #2 or #4, your main speakers are reproducing the entire frequency range (including bass) and it is advantageous for the subwoofer to reproduce only those frequencies below the rated response of the main speakers. For example, if your main speakers have a rated low frequency response of 60Hz, begin with the
If you are using Connection Method #3, your main speakers are reproducing only frequencies above 100Hz, due to the fixed 100Hz high pass filter at the
The selectable HIGH PASS FILTER determines the range of frequencies that the main speakers (“satellites”) will reproduce. For example, a high pass setting of 50Hz means that the main speakers receive a signal con- taining only frequencies above 50Hz. The benefit of high pass filtering is improved dynamic range and lower distortion in the main speakers, as they are spared the task of low frequency reproduction. There are three available high pass settings: 50Hz, 75Hz and 110Hz.
The High Pass Filter should initially be set to a frequency above the rated low frequency limit of the main speak- ers. For example, if your speakers have a rated low frequency response of 40Hz, use the 50Hz
To select the appropriate high pass setting for your main speakers, check the owner’s manual for their rated low frequency response. If you are unable to obtain this information, here are some common

The SUBWOOFER PHASE selector sets the phase of the subwoofer at the 0° position (normal phase) and the 180° position (reverse phase). The ability to adjust subwoofer phase is a great advantage for achieving smooth bass response in your system. The combined low frequency sound waves from the subwoofer and the main speakers can sometimes cause peaks and dips in the frequency response at the listening position. In these cases, adjusting the subwoofer phase may improve the blending and overall performance of the system.
The optimal phase setting will differ according to room conditions and placement, and the main speakers used. Experiment with phase settings by listening to a familiar CD from the listening seat, alternating phase settings on the same track. Do not attempt to evaluate the best sound while standing above the subwoofer or amplifi- er, as the sound at the listening position will be significantly different.
The SUBWOOFER GAIN switch allows you to attenuate the
The SubOne i has a STANDBY MODE feature that is automatic and requires no user adjustment. When no signal is present for 45 minutes, the SubOne i goes into Standby Mode, and it will use a minimum of power to remain “asleep.” When the system is used again, it immediately turns on as soon as a signal is received. There is no need to turn the SubOne i on and off every time it is used.
