Velodyne Acoustics 10, 12 user manual Phase Adjustment - 0/90/180/270, Auto Tur n on Function

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 Tur n 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.
