Low Pass Cr ossover, Subwoofer Dir ect

Rear Panel Connections - Detailed Explanation

Your new subwoofer is equipped with both speaker-level and line-level inputs. Use the RCA/Phono type “INPUT” jacks when connecting your subwoofer to a pre-amp, signal processor, or line-level crossover. The “SPEAKER LEVEL INPUT” jacks connect directly to the speaker outputs of an integrated amplifier or receiver. Your amplifier section will notice no additional loading effects when you use these inputs because of their high impedance.

Note: Do not use both the RCA/Phono “INPUT” connections and “SPEAKER LEVEL INPUT” connections simultaneously.

Low - Pass Cr ossover

Both sets of inputs sum the left and right channels together and the resulting signal is passed through an adjustable low-pass crossover before being amplified. The crossover control allows you to adjust the upper limit of the subwoofer’s frequency response from 40 to 120 Hz. The subwoofer’s response will begin rolling off above the frequency you set this control to. (See note above about frequency limits.)

You should set the crossover frequency to obtain a smooth and seamless transition from the subwoofer to the main speakers in your system. Do this by listening to the blend between your satellites and subwoofer using familiar material. If your main speakers are smaller units with limited low frequency output, you may wish to choose a higher frequency (such as 100 -120 Hz) than you would with larger speakers which have greater low frequency output. With larger speakers, you might start with this control set lower, such as 70 Hz.

Subwoofer Dir ect

Subwoofer Direct is the leftmost setting on the low-pass crossover knob and will allow frequencies up to 200 Hz into the subwoofer. If you are not using an external crossover, we recommend that you use the one provided within the subwoofer for optimum performance.

Caution!!!

To avoid damage to your main amplifier, be sure to maintain correct polarity when making all connections. Red (positive) to red, and black (negative) to black. Be sure that all connections are tight, and that there are no loose strands or frayed wires.

Power Switch

The master power switch is located on the middle left half of the unit. This rocker style switch is the main on/off for the unit. This switch should be set to position 1 for on (up), 0 for off (down).
