Installation
Your new subwoofer system provides for a number of installation options.
Read all the installation information below in order to determine which
installation option is best for your system. Remember to perform all
installation procedures with system power turned off.
Inputs
Your new subwoofer is equipped with both speaker-level and line-level
inputs. Use the LINE-IN jacks when connecting your subwoofer to a pre-
amp, signal processor, or line-level crossover. The FROM AMPLIFIER
jacks connect directly to the speaker outputs of a 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 LINE-IN and FROM AMPLIFIER inputs simultaneously.
Volume control
This control allows you to balance the output from the subwoofer to the
main speakers in your system. This control should be set to achieve similar
volume level from both the main speakers and subwoofer.
Low-pass crossover
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.
You should set the crossover frequency to obtain a smooth and seamless
transition from the subwoofer to the main speakers in your system. If your
main speakers are smaller units with limited low frequency output, you
may wish to choose a higher frequency (such as 100-120Hz) 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 80Hz.
Subwoofer Direct
A bypass switch is also provided if you wish to use an external crossover.
If you are not using an external crossover, we recommend that you use the
one provided within the unit for optimum performance.
