Velodyne Acoustics Audio/Video Subwoofer System Line-Levelconnection - Option A, Power Switch

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 low pass 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.

LINE-LEVEL CONNECTION - OPTION A

Figure 1 shows connection from your home theater receiver to the LFE input on the back of your subwoofer. When the subwoofer is installed in this fashion, all of the low frequency information from your “LFE Out” or “Subwoofer Out” on the back of your receiver will pass into your Velodyne subwoofer. This connection is the most common connection method when using your subwoofer with a 5.1 receiver. (Cable needed: 1 mono RCA cable.)
