INTRODUCTION The Niles StageFront Pro15SW 15-inch High-Power Home Theater Powered Subwoofer is expressly designed for superior sonic quality in home theater and multi-channel music bass reinforcement applications. It employs advanced technology components that extract powerful bass in recorded music or the thunderous deep sound effects in a movie. The Pro15SW is the perfect choice wherever enhanced bass sound is the most important consideration.
IMPORTANT SAFETY INSTRUCTIONS CAUTION CAUTION: TO REDUCE THE RISK OF ELECTRICAL SHOCK, DO NOT REMOVE COVER. NO USER SERVICEABLE PARTS I N S I D E . R E F E R SERVICING TO QUALIFIED SERVICE PERSONNEL. 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.
FEATURES AND BENEFITS 15-INCH INTERLACED CARBON-FIBER WOOFER WITH CAST ALUMINUM FRAME AND BUTYL-RUBBER SURROUND The Pro15SW’s long-throw front-firing 15” woofer creates deep authoritative bass at sustained output levels. 1,000 WATT ADVANCED DIGITAL AMPLIFIER Niles uses the latest digital technology so bass response will be extremely fast and absolutely accurate, no matter what audio material is being reproduced. The efficient design means little heat is generated.
MUSIC SENSE AND 12 VOLT TRIGGER CIRCUITRY FOR AUTOMATIC POWER ON/OFF When enabled, the Pro15SW will turn on when an audio signal is present and remains on any of the audio inputs. The 12-volt System trigger input functions in the same fashion. Power will turn off when no signal is present after a delay of approximately 15 minutes for Music Sense or for the 12-volt trigger.
INSTALLATION CONSIDERATIONS RCA CABLE For line-level connections, use high-quality RCA cables that feature low impedance, double shielding and gold-plated connectors (see CONTROLS AND CONNECTORS on page 7). Consult your local Niles dealer for their recommendations. LOUDSPEAKER WIRE Use 2-conductor loudspeaker wire for loudspeaker-level connections to the Pro15SW and satellite loudspeakers (see CONTROLS AND CONNECTORS on page 7). For these applications, we recommend using 16-gauge wire.
INSTALLATION CONSIDERATIONS (CONTINUED) Because all rooms are unique and people have different expectations with regard to audio quality, some experimentation may be necessary with regard to placement and control settings. Figure 1. A standard placement with the subwoofer right of center. Figure 2. Placed in the front right of a home theater room.

CONTROLS AND CONNECTORS (CONTINUED) SIGNAL CONNECTORS AND POWER CONTROLS The Pro15SW’s signal connectors and power controls are located on the unit’s rear panel, as shown in Figure 4. They function as follows: NOTE: SEE APPLICATIONS STARTING ON PAGE 10 FOR DETAILED WIRING CONNECTIONS FOR YOUR APPLICATION. 2 3 1 53*((&34 4 4:45&. 0/ 0'' */ 065 .07*& .0%& */ 065 "-8":4 0/ 7 7%$ "$ %$ N" 7 7%$ "$ %$ N" .
NOTE: ON THE FRONT PANEL IF SETUP (SEE FIGURE 3 ON PAGE 7) SWITCH IS SET TO MUSIC, A 3 TO 30 VDC (OR VAC) TRIGGER SIGNAL WILL CHANGE OPERATION OVER TO THE MOVIE MODE. IF THE SETUP SWITCH IS ALREADY SET TO MOVIE, A TRIGGER SIGNAL HAS NO EFFECT, SINCE THE MODE IS ALREADY SET TO MOVIE. NOTE: FOR A HOME THEATER RECEIVER NOT EQUIPPED WITH A MOVIE/MUSIC TRIGGER OUTPUT, CONSIDER ADDING A NILES HOME THEATER AUTOMATION SYSTEM OR A NILES MAIN SYSTEM UNIT. SEE FIGURE 9 ON PAGE 14 FOR CONNECTION DETAILS. 3.
CONTROLS AND CONNECTORS (CONTINUED) APPLICATIONS The StageFront Pro15SW 15-inch High-Power Home Theater Powered Subwoofer is very flexible and can be configured for use in various applications with associated external audio components, as shown in Figures 5 through 9.

FINISHING THE INSTALLATION ADJUSTING THE FEET The Pro15SW is equipped with four adjustable spike feet that include large slip-on rubber covers. At the final placement site adjust the feet/spikes as follows: ■ On hard floors (e.g., wood, tile, etc.), check the Pro15SW’s stability and if needed, adjust the rubber feet one at a time until the cabinet is level. ■ On carpeted floors, tilt the Pro15SW up and remove each rubber cover.
■ HIGH PASS FREQUENCY control (if applicable) = 160 Hz (or value recommended by satellite loudspeaker manufacturer) ■ HIGH PASS ON/OFF switch = ON ■ LEVEL SETUP switch = MUSIC ■ MUSIC LEVEL control = 5 ■ MOVIE LEVEL control = 5 ■ LOW PASS FREQUENCY control = 120 Hz ■ PHASE control = 0° 3. While playing a favorite music track, adjust your system’s volume control to a comfortable level and listen to the bass level at your favorite listening position (e.g., couch).
Of course, there are some wires that appear completely identical. So be careful, or you might make a connection mistake. If you do, one satellite loudspeaker will be playing “out-of-phase” with the other loudspeaker. A pair of out-of-phase loudspeakers works against each other, and the sound of the two playing together will be lacking in bass and sound “phasey.” If you suspect the sound is not right, and you cannot see any markings on the wire, try this simple test: 1.
