Note: A pair of Velodyne subwoofers is a very common setup and doubles your system’s bass capability. When using a pair of Velodyne subwoofers in stereo, it is preferable to place each subwoofer by the speaker of the corresponding channel. In this case you may have to use more than one “Y” splitter.

The SPEAKER LEVEL jacks connect directly to the speaker outputs of any amplifier, integrated amplifier, or receiver. Your amplifier section will notice no additional loading effects when you use these inputs due to their very high impedance. If using the SPEAKER LEVEL inputs, you DO want to connect both channels, since different bass information might be present in each channel going to your main speakers.

IMPORTANT!

Do not use both LINE LEVEL and SPEAKER LEVEL connections simultaneously!

Caution! To avoid damage to your main amplifier, be sure to maintain correct polarity when making all connections - red (positive) to red, and black (negative) to black. Be sure all connections are tight, and that there are no loose strands or frayed wires.

Volume Contr ol

This control allows you to balance the output from the subwoofer to the main speakers/amplifier in your system. 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 at the 9:00 position.

Low - pass Cr ossover - 50 to 200 Hz

A loudspeaker driver is incapable of handling all sound reproduction across the entire audio spectrum by itself. Thus, the crossover splits the frequency spectrum into different pieces, which are then handed over to individual speaker drivers. Each driver receives only the signal in its usable frequency range and the distortion in each driver is reduced.

All line level inputs on the subwoofer 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 ask a friend to adjust the phase switch from one position to the other and listen for a change in mid-bass output. The correct position will have a greater amount of apparent mid-bass output.
