ERS Receiver Processor Subwoofer Outputs The Velodyne subwoofer is designed to operate using the full range audio signal for input when using the built in crossover Many home theater processors receivers Dolby Digital DTS THX have a subwoofer out jack sometimes labeled that is internally filtered settable at the receiver processor and designed to be used with a powered subwoofer In some installations it may be beneficial to use BOTH the Velodyne crossover and the receiver processor crossover resulting in a steeper ultimate crossover slope 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 crossover in either the processor or your VX 11 subwoofer Or simply set one crossover to a higher frequency such as 120 Hz will restore maximum performance Refer to Figure 2a Line Level Subwoofer Connection Diagram and Figure 2b Speaker Level Subwoofer Connection Diagram pages Z and 8 for connection diagrams WWW VELODYNE COM VX 11 User s Manual 5 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 most any of which will work perfectly well We do recommend that you keep the length of cable as short as possible to avoid any potential
