Detailed instructions for use are in the User's Guide.

[. . . ] Care ­ From time to time you should wipe off the front and side panels and the cabinet with a soft cloth. Do not use rough material, thinners, alcohol or other chemical solvents or cloths since this may damage the finish or remove the panel lettering. Lightning ­ For added protection for the subwoofer during a lightning storm, or when left unattended and unused for a long period of time, unplug it from the wall outlet. This will prevent damage to the subwoofer due to a lightning strike and power-line surges. [. . . ] With its built-in amplifier, the R12DT fits into to any system, and is tuned for both stereo music audio and for a home theater surround setup. The R12DT filters out mid- and high-range frequencies by sending bass-only signals to its own amplifier via an active crossover network. Port Port DUAL TUNED PORT DESIGN The R12DT subwoofer ports are tuned to provide optimum bass reinforcement for systems designed primarily for home theater entertainment or for music listening. This tuning provides an increase in low frequency output which is more ideal for movies where explosions and other action sounds need greater impact. For music applications, one of the ports is blocked with the included plug. This tunes the enclosure for a flatter response with extended low frequency response. It will produce lower notes and do so more accurately. Woofer The front-firing 12-inch woofer has a 50mm diameter voice coil and vented pole piece for high power handling and more efficient operation. Subwoofer front (grille removed) CONNECTIONS When you make connections make sure the power switches of all components are off, including the subwoofer. Audio Cables If you are connecting your subwoofer into a system made up of separate components (preamps and power amps), you will need audio cables long enough to reach the subwoofer from the preamplifier and the power amplifier. Speaker Wire Typical speaker wire has a pair of separate conductors with insulating jackets that are molded together. We recommend that you use 16-gauge wire for connecting the receiver to the front speakers. Polarity All speakers in a system must be connected with the same polarity. Speaker wire is marked for polarity so that you can identify which wire in the pair is which. Polarity is shown by a color strip on the insulation, by ridged molded into the insulation or be the colors of the wires, one copper and one silver. Strip the insulation from speaker wire ends to reveal the bare conductors before connecting to receiver, subwoofer or speaker terminals. Note: Always connect the red (+) terminal on the receiver to the red (+) terminal on the subwoofer, and the black (­) terminal on the receiver to the black (­) terminal on the subwoofer. The same is true for connecting the receiver outputs to the front speakers red (+) to red (+) and black (­) to black (­). 3 R12DT SUBWOOFER 1 2 3 10 4 5 6 7 8 9 1 Speaker Level Input: (with passthrough) Binding post terminals will accept up to 12 gauge speaker wire or banana jacks. Allows input connections to be sourced from an amplified speaker signal such as the Left and Right output from an amplifier/receiver. This amplified signal is tapped off for feeding the subwoofer but the signal is unaltered and is passed directly on to adjoining output terminals. External Heat Sink: Provides heat dissipation for the subwoofer's internal amplifier. Do not cover or place against another object as this may impair its performance. Volume Level Adjustment: Increase or decrease the output level relative to the incoming signal. Crossover: Provides active filtering of the incoming signal to allow only lower frequencies to be amplified. Phase Selection: The speaker Phase can be variably adjusted up to 180 degrees. Used with more than one subwoofer or for abnormal room acoustics. 6 Power Auto, On and Off: Auto setting - amplifier turns on when audio is detected. [. . . ] Accidental damage and shipping damage are not considered defects under the terms of the warranty. Russound assumes no responsibility for defects resulting from abuse or servicing performed by an agency or person not specifically authorized in writing by Russound. Damage to or destruction of components due to improper use voids the warranty. To return for repairs, the unit must be shipped to Russound at the owners expense, along with a note explaining the nature of the service required. [. . . ]
