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. [. . . ] This control should be set to achieve similar output levels from both the main speakers and subwoofer when listening to music. A good starting point for the volume control is two or three graduations from minimum. Warning: Some manufacturers preset their receivers with the Sub-Out channel signal at a minimum level. It is very important to verify that your receiver Sub-Out channel is set to the same output level as your front right and left channels. Refer to your receiver manual for the individual channel level adjustment procedure. If your receiver Sub-Out channel is set too low, the subwoofer may appear to have a weak output, it may sound noisy or distorted, and the Auto On/Off feature may not operate properly. . www. velodyne. com Impact Series User's Manual 3 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. 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 units 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. With larger speakers, you might start with this control set lower, such as 80 Hz. 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 mid-bass frequency output. The correct position will have a greater amount of apparent mid-bass frequency output. For all installations, experiment with the phase switch to determine the setting (0 or 180 degrees) that produces the most mid-bass. If the settings sound similar, we recommend the "0" position. A u t o Tu r n o n F u n c t i o n 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. 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 VOLUME CONTROL section on previous page. . www. velodyne. com Impact Series User's Manual 4 R e a r Pa n e l C o n n e c t i o n s 2 3 4 5 1 6 7 Figure 1.
