Phase Adjustment - 0°/90°/180°/270°
All inputs sum the left and right channels together, with the resulting signal passing through an adjustable
low-pass crossover before being amplified. The crossover control allows you to adjust the upper limit of the
subwoofer’s frequency response from 40 to 120 Hz. The subwoofer’s response will begin rolling off above the
frequency you set this control to. you should set the crossover frequency to obtain a smooth and seamless
transition from the subwoofer to the main speakers in your system. If your main speakers are smaller with limited
low frequency output, you may wish to choose a higher frequency (such as 100 - 120 Hz) than you would with
larger speakers which have greater low frequency output. The default crossover setting is 80 Hz. with larger
speakers, you may want to set this even lower, for example 70 Hz.
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 “Always On” position. In order to activate
the circuit, change the switch to “Stand-by”.
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.
