Unpacking the Subwoofer If you suspect damage from transit, report it immediately to your dealer. Keep the shipping carton and packing materials for future use. PLACEMENT Since the installation of a subwoofer can be somewhat more complicated than installing full-range speakers, it is essential that you read this section very carefully prior to connecting the subwoofer to your system. Should you have questions relating to your installation, it is advisable to call either your dealer or Infinity's Customer Service Department for advice. The performance of the subwoofer is directly related to its placement in the listening room and how you align the subwoofer with its satellite speakers. Setting the volume of the subwoofer in relation to the left and right speakers is also of critical importance because it is essential that the subwoofer integrate smoothly with the entire system. Setting the subwoofer's volume level too high will result in an overpowering, boomy bass. Setting the volume level too low will negate the benefits of the subwoofer. Here are several additional facts on installation that may prove useful. It is generally believed by most audio authorities that low frequencies (below 125Hz) are nondirectional and, therefore, placement of a subwoofer within any listening room is not critical. While in theory it is true that the larger wavelengths of extremely low frequencies are basically nondirectional, the fact is that, when installing a subwoofer within the limited confines of a room, reflections, standing waves and absorptions generated within the room will strongly influence the performance of any subwoofer system. As a result, the specific location of the subwoofer becomes important, and we strongly recommend that you experiment with placement before choosing a final location. Placement will depend upon your room and the amount and quality of bass required (for example, whether or not your room permits placement of the subwoofer near either satellite). Left Surround Channel Before deciding where to best place your speakers, survey your room and study Figures 1 and 2.

The volume control setting on your processor/preamp or receiver is not a specific indication of the overall loudness level of the speakers.The only important consideration is the loudness level at which the system can be played, regardless of where the volume control is set. Always turn down the volume control setting on your processor/ preamp or receiver when changing a cassette or CD, or switching inputs to AM or FM operation. Excessively loud transients (clicks or popping sounds) can damage the satellite speakers and possibly the subwoofer.

Some Dolby Digital-equipped receivers/processors offer different setup options for each source or surround mode, e.g., CD-stereo, videotape, Dolby or Pro Logic. In each case, follow your equipment's instructions to ensure that the subwoofer output is turned on and that the speakers are set to "Small" in each mode. Crossover Adjustment The Crossover Adjustment Control ¢ determines the highest frequency at which the subwoofer reproduces sounds. If your main/satellite speakers can comfortably reproduce some lowfrequency sounds, set this control to a lower frequency setting, between 50Hz and 100Hz.This will concentrate the subwoofer's efforts on the ultradeep bass sounds required by today's films and music. If you are using smaller speakers that do not extend to the lower bass frequencies, set the Crossover Adjustment control to a higher setting, between 120Hz and 150Hz. NOTE: This control will have no effect if the LFE/Normal Switch is set to LFE. If you have a Dolby Digital or DTS receiver/ processor, the Low-Pass Frequency is set by the receiver/ on the subwoofer to processor. Set the LFE/Normal Switch LFE. Consult your owner's manual to learn how to view or change this setting. A setting of 100Hz ­ 120Hz is recommended when using the TSS-SUB750 with Infinity Total Solution satellites. Power On Plug your subwoofer's AC cord into a wall outlet. Do not use the outlets on the back of the receiver. Initially set the Subwoofer Level Control to the"MIN" position. on the Turn on the subwoofer by pressing the Power Switch rear panel. Turn on your entire audio system and start a CD or movie soundtrack at a moderate level. Phase Control The Phase Switch determines whether the subwoofer speaker's piston-like action moves in and out with the main speakers, 0°, or opposite the main speakers, 180°. Proper phase adjustment depends on several variables such as room size, subwoofer placement and listener position. Adjust the phase switch to maximize bass output at the listening position. Auto On/Standby With the Power Switch in the ON position, the LED on the front panel will remain lit in red or green to indicate the On/Standby mode of the subwoofer. RED = STANDBY (No signal detected, amp off) GREEN = ON (Signal detected, amp on) The subwoofer will automatically enter the Standby mode after approximately 10 minutes when no signal is detected from your system.The subwoofer will then power on instantly when a signal is detected. During periods of normal use, the Power Switch can be left on.You may turn off the Power Switch for extended periods of nonoperation, e.g., when you are away on vacation.
