Optimum User’s Manual
(1) Power Switch
This button forces your Optimum subwoofer into standby mode. The numeric LED shuts off
and the sub puts out no power. The sub will remain in this mode until the POWER button is
pressed again. To fully deactivate (i.e. power button) the sub, use the main power switch on
the back panel.
(2) LED Numeric Display
This LED supplies information on volume, crossover, presets, and other information. The
“Light” button on the remote deactivates this display.
(3) Volume Control
These buttons allow you to balance the output from the subwoofer to the main speakers in
your system. The volume should be set to achieve similar volume level of both the main
speakers and subwoofer. The default volume is 30. The upper button increases the
subwoofer level and the lower button decreases it.
Note: Volume can also be controllable by using the supplied remote.
WARNING: Some manufacturers preset their receivers with the Sub-Out (A.K.A. LFE)
channel signal at a minimum level. It is very important to verify that your receiver Sub-Out
channel is set to the same output level as your front right and left channels. Refer to your
receiver manual for the individual channel level adjustment procedure. If your receiver
Sub-Out channel is set too low, the subwoofer may appear to have a weak output, it may
sound noisy or distorted, and the Auto On/Off feature may not operate properly.
(4) Mic Input
Connect the supplied microphone for the Auto-EQ feature to this mini-jack input.
