Phase Adjustment - 0°/90°/180°/270°
This control allows you to change the phase of the subwoofer’s output signal to correct for any possible 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.
