(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.
