ADJUSTABLE LOW-PASS, HIGH-PASS,
AND PHASE CONTROLS
Variable low-pass and high-pass filters divide the incoming stereo audio spectrum into separate signal paths for the mono subwoofer reproduction and stereo pass-through to a pair of satellite loudspeakers. A fully-adjustable (0-to-180 degree) phase control ensures optimal system integration, no matter where the SW300 is placed in the room.
MUSIC SENSE CIRCUITRY FOR AUTOMATIC POWER ON/OFF
When activated, the SW300’s music sense circuits will continually monitor the audio inputs and automatically power on the subwoofer when audio signals are detected. Conversely, the music sense circuits will automatically power off the subwoofer, after a preset time, when signals are no longer present. The SW300 also includes a POWER TRIGGER input that allows a 12 volt input to remotely power on/off the SW300 in the same way.
CASCADE AUDIO OUTPUTS FACILITATE EASY CONNECTION OF ADDITIONAL WOOFERS
For larger rooms, or stereo subwoofer applications, several SW300’s can be easily added to a home theater system using the cascading line-level audio outputs to feed additional SW300 audio inputs in a daisy-chain connection.
ATTRACTIVE, YET RIGID, COMPACT CABINET WITH REMOVABLE METAL GRILLE
The SW300 is housed in an attractive, compact, 11-layer no-void, birch-ply, cross-braced black cabinet that provides the ultimate in rigidity and sound clarity. The black perforated-metal grill is removable for those interested in showcasing the technology.
ADJUSTABLE ISOLATING FEET
The SW300 is equipped with four adjustable spike feet (pre-installed with large slip-on rubber covers) that mechanically couple the woofer cabinet to a hard floor. For carpet placement, the rubber covers can be removed to reveal the spikes.
DOLBY® DIGITAL READY
The SW300 is specifically designed for Home Theater Sound. This model exceeds the specifications set forth by Dolby Laboratories for the accurate reproduction of Dolby Digital-Encoded Sources.
INSTALLATION CONSIDERATIONS
RCA CABLE
For the best possible performance using the line-level connections, use high-quality RCA cables that feature low impedance and gold-plated connectors. Consult your local Niles dealer for their recommendations.
LOUDSPEAKER WIRE
Use 2-conductor loudspeaker wire when connecting loudspeakers to your receiver or amplifier. For most applications, we recommend using 16- or 18-gauge wire. For wiring runs longer than 80 feet, we recommend 14-gauge wire. The binding post terminals will accommodate up to 12-gauge wire directly. Larger sizes can be accommodated via pin connectors.
When running wire inside walls or ceilings, always use (CL-2 or CL-3) rated cable. In some areas, conduit is also required. For a trouble-free installation, low-voltage wire such as speaker wire must be run in accordance with the National Electrical Code and any applicable provisions of the local building code. If you are unsure of the correct installation techniques, wire jacket, or type of conduit to use, consult a professional audio/video installer, building contractor, or the local building and inspection department.
TECH TIP
Wire size is expressed by its AWG (American Wire Gauge) number – the lower the number, the larger the wire. For example, 12 AWG is physically larger than 14 AWG.
NOTE: THE NILES SW300 POWERED SUBWOOFER IS EXPRESSLY DESIGNED FOR USE IN HOME THEATER AND MUSIC APPLICATIONS. FOR HOME THEATER FRONT- OR CENTER-CHANNEL APPLICATIONS, WE RECOMMEND USING A NILES PHD, HDLCR, OR HDLCRBX LOUDSPEAKER. FOR REAR-CHANNEL APPLICATIONS, WE RECOMMEND USING A NILES HDFX, CM6HDFX, OR DS LOUDSPEAKER.
