RECOMMENDED SETUP PROCEDURES (continued)
Subwoofer System Setup:
Once you have set the controls on your home theater receiver or preamp/ processor and on your Fathom(s) to the settings recommended on pages 26 and 27, you are ready to begin setting up your Fathom for optimum performance.
1) Level Setting
Using familiar music or movie material with deep bass content, adjust the subwoofer level to blend with the other speakers using your receiver or preamp / processor’s subwoofer level control. This method is more immune to tampering than using the Fathom’s “Master Level” knob (think toddlers or curious visitors). In the unlikely event that the subwoofer level control in your receiver or preamp/processor cannot be turned up enough to level match the Fathom, return
that control to “0”. Then, flip the Fathom’s “Level Mode” switch to “Variable” and with “0” as your reference point (REF mode gain and Variable “0” gain are identical) use the “Master Level” control to level match the subwoofer with the other speakers. MAKE NOTE OF THIS SETTING FOR FUTURE USE.
For more detailed information on your Fathom’s level setting controls, please refer to the “Level Mode” and “Master Level” sections on pages 15 - 16 of this manual.
2) Polarity and Phase Adjustment
It is often helpful to have a second person operating these controls so that you can easily hear the changes from the primary listening seat.
Listening to familiar source material (preferably music with good upper bass and midbass response), flip the “Polarity” switch from “0” to “180” and listen for differences. The correct setting will sound most natural with the best upper bass punch and articulation. If both sound similar, choose “0”.
Once Polarity is set, use the same music material to audition different “Phase” control settings and choose the one that further enhances the upper and midbass response. If you can’t hear a difference, set the control to “0.”
3) Experiment with alternative subwoofer locations (if necessary).
If you are satisfied with the basic performance of your subwoofer you are ready to move on to the next step. If not, we recommend that you experiment with the position of your subwoofer until you are pleased with its basic performance. Experimentating with placement is KEY to a superior sounding system. Moving the subwoofer just a few feet can have a significant effect on the smoothness of the bass. For each new position, start with the polarity and phase controls at “0” and repeat the setup process beginnng with Step 1.
