Congratulations Congratulations on your purchase of a Velodyne Impact subwoofer system. This system represents the state-of-the-art in home audio reproduction and will provide you with years of listening pleasure when properly used and cared for. Read and follow this instruction manual to ensure safe and proper system connection and operation. Caution! Please observe the following instructions to insure safe and proper system operation.
Placement The first step in installing your new Impact sub is to determine where it will be placed in the room. Unpack the system carefully and use the following guidelines in order to find the best room placement option. True subwoofers operate at extremely low frequencies which are primarily omni-directional. Keep in mind that frequency response and output level can be drastically influenced by placement, depending on the acoustic properties of the listening room.
To alleviate this condition, we recommend the following steps: 1) If using line level jacks, BOTH THE LEFT AND RIGHT INPUT SHOULD ALWAYS BE USED – never use just the left or just the right input. If the subwoofer’s input comes from the LFE channel of your receiver, use the included “Y” splitter to supply the single input to both connectors for the Left and Right subwoofer inputs.
Low-pass Crossover - 50 to 200 Hz As noted above, 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 50 to 200 Hz. The subwoofer’s response will begin rolling off above the frequency you set this control to.

Interconnect Cables When installing your new Velodyne subwoofer using the line level connections, you should always use shielded phono cables. There are many high quality cables available today. It is recommended that you keep the length of cable as short as possible to avoid any potential noise problems. When using speaker level connections, use a high quality speaker cable that mates well with the connectors.
T roubleshooting and Service Before seeking service for your amplifier or subwoofer, please re-check all systems. Following is a simple troubleshooting guide to assist you. 1. 2. 3. 4. 5. Verify that the unit is plugged in and power outlet used is active. Is the power switch on? Is the unit receiving an input signal from your source? Have all controls (volume, crossover, phase, etc.) been properly set? If the unit has been running at high levels, one of the protection circuits may be engaged.
