1. Power Indicator. This light is illuminated blue when the subwoofer is
turned on and playing, and it illuminates red when the subwoofer is in on,
but in Standby mode.
2. Volume Control. Volume control gives the ability to match the output
level of the subwoofer to the level of your satellite/main speakers. The
subwoofer output will increase as this control is rotated clockwise. To
prevent damage to the subwoofer during installation, turn the volume
down before turning on your subwoofer.
3. Crossover. This controls the crossover frequency between 50 Hz and
160 Hz.
Set to 50 Hz - 160 Hz: the subwoofer will reproduce frequencies
below 50 Hz. Rotating the control clockwise will smoothly increase this
frequency range up to 160 Hz.
Set to LFE: If your processor does not have its own subwoofer
crossover frequency control, rotate this control until the bass sounds
natural. If the mid-bass sounds natural but you want more low bass,
turn the crossover frequency down a little, then turn the volume up
by about the same amount. This increases the low-bass output while
leaving the mid-bass output the same.
4. Turn-on Mode Switch. In addition to the master Power Rocker Switch,
the subwoofer has 3 additional Turn-On modes.
a. When the switch is set to ON, the subwoofer will remain powered on
and will not turn off when audio signal disappears.
b. When the switch is set to AUTO, after approximately 15 minutes with
no signal, the subwoofer will enter Standby mode. It will turn back on
when an audio signal is detected.
c. When the switch is in the OFF position, the subwoofer will not turn on,
regardless of the Power Rocker Switch position.
5. Power Rocker Switch. Press the top of this rocker switch to turn the
subwoofer's master power ON or OFF.
6. Voltage Selection Switch. This switch is used to select the compatible
electrical voltage for the installation location. Please check with your local
electrical requirements before making changes to this setting.
7. Phase. This controls the relative phase of the subwoofer with respect to
your other speakers. Use this to help blend the subwoofer with the rest of
the system.
