Following are brief descriptions of the connections described in Figure 2. more detail on these connections can
be found in the next section.
(1) LOW-PASS CROSSOVER
Use this knob to select the frequency above which you wish to roll off the signal to the subwoofer. When
the knob is turned all the way to the left, the Subwoofer Direct feature is invoked and the subwoofer
plays all frequencies up to 200 Hz.
(2) 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 between both the main speakers and
subwoofer. when pressing volume up or down, set the level while watching the lED display for reference.
The upper button increases the subwoofer level and the lower button decreases it.
Note: Volume is also controllable by using the supplied remote. when defaults are restored, the default
volume setting is 30 out of 80.
(3) AUTO ON/OFF Switch
Use this switch to select between auto-on (active) and constant on (auto-on inactive) operation.
(4) LINE OUTPUT
Connect these jacks to the LINE IN amp input to use the Optimum subwoofer’s internal high pass
crossover. See below for a more detailed explanation of this crossover.
(5) LINE INPUT/LFE Input
Connect these jacks to the LINE OUT preamp output, LFE output or subwoofer output jacks of your
receiver/processor. If using the lFE output from your receiver or processor, plug the single cable into the
“l” - lFE input or for more signal, use a “y” connector (not included) and feed the signal into both “R”
and “l” inputs.
(6) 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.
(7) IR Input
This is a connection that allows the utlization of a third party infrared remote sensor, such as Elan or
Xantech, or an extended cable for placement closer to your other remote controlled equipment. This
keeps you from awkward control angles using the infrared remote control.
(8) 12v Trigger
When this 2-conductor mini jack is connected, the amplifier remains in power-off mode until the trigger
is applied. The correct trigger is +12V on the tip of the connector relative to the grounded sleeve.
