(6) HIGH PASS CROSSOVER Switch
This switch selects the frequency for the high pass crossover.
This crossover is functional on both line and speaker-level
outputs. Smaller speakers with limited low frequency output may
perform better using the higher 100 Hz setting that will reduce the
low frequencies sent to them. Larger speakers with greater low
frequency output may be able to handle the 80 Hz setting without
strain.
(7) SPEAKER LEVEL INPUT Terminals
Connect these input terminals to the speaker output terminals
of your amplifier or receiver. If you use this method of
connection, when you go to the receiver speaker set up menu,
make sure you select the large speaker option.
(8) SPEAKER LEVEL OUTPUT Terminals
Sends a crossed-over speaker-level signal to the front speakers.
See below for a more detailed explanation of this crossover.
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 connect-
ing 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 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.
