The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. WARNING: To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture. 2 PSW-8 (230V) Infinity PSW-8 ® The Infinity PSW-8 powered subwoofer continues the longstanding Infinity commitment to accurate sound reproduction. [. . . ] Be sure to leave a minimum of 15cm between the wall and the port on the subwoofer. Figure 1. This example shows the subwoofer positioned behind the right-channel satellite speaker to re-create the actual location of bass instruments in an orchestra and/or add impact to movie soundtracks. INSTALLING SPIKED FEET Four metal spikes are supplied for use when the subwoofer is to be placed on a carpeted surface to decouple the subwoofer from the floor and prevent unwanted damping. To insert the spikes, gently lay the subwoofer on its side on a soft, nonabrasive surface. Each spike then screws into the threaded insert, in the center of the foot. NEVER drag the speaker to move it, as this will damage the spikes, the feet, the wood cabinet itself, and/or the floor. Always lift the speaker and carry it to its new location.

In that case, it is recommended that you use a Y connector (not included) to maximize performance. PSW-8 (230V) 5 ENGLISH SUBWOOFER CONNECTIONS OPERATION POWER ON Plug your subwoofer's AC cord into a wall outlet. Initially set the Subwoofer-Level Control ¡ to the "min" position. Turn on your sub by pressing the Power Switch ¶ on the 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. CROSSOVER ADJUSTMENTS The Crossover Adjustment Control TM determines the highest frequency at which the subwoofer reproduces sounds. If your main speakers can comfortably reproduce some low-frequency 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 bookshelf 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 Input ¢ is used. If you have a Dolby Digital or DTS processor/receiver, the Low-Pass Frequency is set by the processor/receiver. Consult your owner's manual to learn how to view or change this setting. AUTO ON/STANDBY With the Power Switch ¶ in the ON position, the LED § on the rear 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. You may turn off the Power Switch ¶ for extended periods of nonoperation, e. g. , when you are away on vacation. If no sound emanates from the subwoofer, and the power LED is not on at all, check the AC-line cord. [. . . ] Adjust the Subwoofer-Level Control ¡ until you obtain a pleasing blend of bass. Bass response should not overpower the room but rather be adjusted so there is a harmonious blend across the entire musical range. Many users have a tendency to set the subwoofer volume too loud, adhering to the belief that a subwoofer is there to produce lots of bass. A subwoofer is there to enhance bass, extending the response of the entire system so the bass can be felt as well as heard. [. . . ]
