A) On/Auto/Off Switch:
Your subwoofer has an On/Off switch. Once connected to your receiver and plugged into the wall out-
let, the Ultimate subwoofer will need to be turned on and can be left in the “auto” position so that once
it senses a signal coming from your receiver, it will automatically turn on and will turn off into Standby
mode after it does not sense a signal for 5 minutes.
B) Setting the Volume and Crossover Frequency.
F
REQUENCY
:
The Crossover Frequency control determines the frequency below which the subwoofer will play. This
frequency is manually controlled and is continuously variable between 60-150Hz. You can experiment
with which position works best with your main speakers by turning this control until the sound of the
low frequency coming from the subwoofer is nicely blended with the sound of your main speakers.
F
REQUENCY SETTING TIP
:
When using small speakers (speakers with a 6" or less main woofer) set this control toward the
"150" position. When using larger speakers (speakers with an 8" or more main woofer) set the con-
trol closer to the "60" position.
G
AIN
:
When setting the volume control at the subwoofer, begin with your main speakers playing at a normal
listening level and the volume control at the subwoofer completely in the off position (counterclockwise
position). Then, begin to turn up the volume at the subwoofer slowly (clockwise) until the desired bass
response is achieved. Bass output will then be regulated by your A/V receiver’s volume control.
G
AIN SETTING TIP
:
Have one person sit at the regular listening position, and a second person turn up the volume at the sub-
woofer until the desired bass output is achieved at the listening position. Remember most natural sound-
ing bass results when bass reproduction is balanced with the main speakers.
P
HASE
:
The phase control will fine tune the bass performance. Have one person sit in the listening position and
a second person toggle the switch between Normal and Reverse to achieve the desired bass output.
