Cr ossover Switch - INTERNAL X - OVER/SUBWOOFER DIRECT

This switch allows the internal crossover circuitry to be removed from the signal path. This is required in certain installations which route the signal through external processors with a crossover circuit of their own, such as the new digital units. Simply move the switch to SUBWOOFER DIRECT to disengage the built-in crossover. For all other installations which do not have a separate electronic crossover, we recommend you leave the switch set to INTERNAL X-OVERto provide optimum performance.

Auto Tur n on Function

With this function in the “auto” position, your subwoofer can be safely left with the main power switched on continuously. The subwoofer will turn itself on automatically when an audio signal is present. If no signal is present for approximately 10 minutes, the unit will switch to standby mode. While in standby mode, your subwoofer will draw very minimal power. This function can be disabled by leaving the switch in the “inactive” position.

Warning:

If the Sub-Out channel signal level from your receiver is too weak, this feature will not operate properly. See VOLUME CONTROL section on previous page.

Power Switch

The master power switch is located on the lower half of the unit. This rocker style switch is the main on/off for the unit. This switch should be set to position 1 (up) for on, and 0 (down) for off. If the unit is to be left unused for an extended period of time, the master power switch should be turned off.

Subwoofer Outputs

The Velodyne subwoofer is designed to operate using the full range audio signal for input when using the built-in crossover. Some processors/receivers have a “subwoofer out” jack that is internally filtered and designed to be used with a conventional amplifier and speaker. In some rare cases, combining both an external crossover and the one internal to the subwoofer may result in low output and increased noise. In these installations you may need to bypass the internal crossover in either the processor or Velodyne subwoofer. In some installations, simply setting one crossover to a higher frequency (such as 120 Hz) will restore maximum performance. To bypass the subwoofer’s internal crossover when the unit is being fed a filtered signal from another crossover, simply locate the switch marked INTERNAL X-OVER/SUBWOOFER DIRECT on the rear panel of the subwoofer and set to the SUBWOOFER DIRECT position. This will eliminate the internal crossover from the signal path.

Note: If not using an external crossover, you should use the built-in crossover for optimal performance.
