Velodyne Acoustics VRP Series user manual Phase Adjustment 0/180, Auto Tur n on Function

Phase Adjustment - 0°/180 °

This control allows you to “reverse” the phase of the subwoofer’s output signal 180° 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 phase switch from one position to the other and listen for a change in low frequency output. The correct position will have a greater amount of apparent low frequency output.

For all installations, experiment with the phase switch to determine the setting (0 or 180 degrees) that produces the most bass. If the settings sound similar, we recommend the “0” position.

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 (Red LED). While in standby mode, your subwoofer will draw very minimal power.
