Optimum User’s Manual
Phase Adjustment - 0°/90°/180°/270°
This control allows you to change the phase of the subwoofer’s output signal to correct for any
p
ossible mismatch and resulting cancellation between the subwoofer and your main
speakers/amplifier. To adjust, simply listen to the system with music playing, then depress the
various phase switches on the remote control and listen for a change in mid-bass frequency
output. The correct position will have a greater amount of apparent mid-bass frequency output.
If the settings sound similar, we recommend the “0” position. See the remote control section
for more information.
Auto Turn on Function
The subwoofer will turn itself on automatically when an audio signal is present. If no signal is
present for approximately eight minutes, the unit will switch to standby mode (blank LED). While
in standby mode, your subwoofer will draw very minimal power. Your sub is shipped in
the “INACTIVE” (always on) position. In order to activate the circuit, change the switch
to “ACTIVE”.
Warning:
If the Sub-Out channel signal level from your receiver is too weak, this feature will not operate
properly and shut the subwoofer off while you are listening to it. To correct this, see the
VOLUME CONTROL section on previous page.
