[. . . ] This symbol indicates that there are important operating and maintenance instructions in the literature accompanying this unit. This symbol indicates that dangerous voltage constituting a risk of electric shock is present within this unit. WARNING: To reduce the risk of fire or electrical shock, do not expose this apparatus to rain or moisture. PLACEMENT Although your Reference Series subwoofer will perform well in a wide variety of locations, you will get the most out of it by following some simple guidelines: Although the subwoofer's orientation is not critical, avoid placing the front (driver) side of the cabinet up against a wall. [. . . ] Others have left- and right-channel line-level outputs, as do some stereo receivers and integrated amplifiers. Separate Preamplifier or Surround Processor -- You will need a pair of Y-adaptors, each with one male RCA plug and two female RCA jacks. Unplug the cables leading from the front left- and right-channel outputs on the preamp or processor and plug the Y-adaptors into them. For each channel, plug the cable leading to the power amplifier into one of the RCA jacks on the Y-adaptor and the cable leading to the subwoofer into the other. ⷠSpeaker Outputs -- Connect the subwoofer's Speaker Level inputs to the same outputs on your receiver or integrated amplifier as your front left and right speakers. This involves running a second set of wires from the left and right speaker outputs to the subwoofer. Maintain correct polarity, with positive (+, red) outputs connected to the positive inputs and negative (­, black) outputs connected to the negative inputs. Make sure that there is no metal-to-metal contact between the positive and negative sides of either connection at either end. Failure to observe this precaution can result in amplifier malfunction or damage. The subwoofer can be connected to a secondary or "B" main channel output of your apmplifier if the volume of your main speakers is unaffected when both outputs are selected. " Then plug the power cord into an AC outlet. You can turn the power on and off manually using the switch, or you can leave the Main Power turned on and set the Auto Power switch to "On, " which will automatically turn the subwoofer on when a signal is detected at one of the inputs and off after a period of inactivity. we recommend Auto Power "On" for most systems. Adjustment -- Start by setting the Crossover Frequency control to the approximate low-frequency limit of your main left and right front speakers. If you don't have their specifications, take an educated guess based on the size of the speakers. A large speaker will usually work down to lower frequencies than a small speaker. So for a large floorstanding loudspeaker, you might start with the Crossover Frequency set all the way down to 40Hz, whereas for very small satellite speakers you might want to turn it all the way up to 120Hz. typical bookshelf speakers would tend to be in the 50Hz to 80Hz range. If the crossover frequency is set higher than 100Hz, the subwoofer should be in the front of the room near the front main speakers. Play a variety of music recordings containing strong but not overpowering bass. Adjust the subwoofer's Level control until the music sounds consistently warm and natural. If you have trouble getting enough low bass without the sound becoming boomy, it probably means the Crossover Frequency is set too high.
