Installation Inputs Your new subwoofer is equipped with speaker-level and line-level inputs. Use the LINE LEVEL jacks when connecting your subwoofer to a pre-amp, signal processor (such as LFE out), line- level crossover, or receiver with pre-amp level outputs. When using the line level jacks, some receivers may not provide enough signal to have the unit’s auto-on feature operate properly. Additionally, this lack of signal may also cause the subwoofer to produce less output than it is capable o

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

Low-Pass Crossover Both sets of inputs sum the left and right channels together and the resulting signal is passed 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

Crossovers Receiver/Processor Subwoofer Outputs The Velodyne subwoofer is designed to operate using the full range audio signal for input when using the built-in crossover. Many home theater processors/receivers (Dolby Digital™, DTS™, THX™) have a “subwoofer out” jack (sometimes labeled “LFE”) that is internally filtered, settable at the receiver/processor, and designed to be used with a powered subwoofer. In some installations, it may be beneficial to use BOTH the Velodyne crossover and the r
