1. 6 i Rear Panel Connections Detailed Explanation Your new subwoofer is equipped with both speaker level and line level inputs Use the RCA Phono type INPUT jacks when con necting your subwoofer to a pre amp signal processor or line level crossover The SPEAKER LEVEL INPUT jacks connect directly to the speaker outputs of an integrated amplifier or receiver Your amplifier section will notice no additional loading effects when you use these inputs because of their high impedance Low Pass Crossover Both sets of inputs sum the left and right channels together and the resulting signal is passed through an adjustable low pass cross over before being amplified The crossover control allows you to adjust the upper limit of the subwoofer s frequency response from 40 to 120 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 Subwoofer Direct Subwoofer Direct is a setting on the low pass crossover knob and will allow frequencies up to 200 Hz into the2. in subwoofer technology John E Johnson Jr Secrets of Home Theater and High Fidelity December 2003 Not only was the little Velodyne the best small sub I ve ever used it was one of the very best subs I ve used John Potis SoundStage April 2002 Velodyne Acoustics Inc 345 Digital Drive Morgan Hill CA 95037 408 465 2800 voice 408 779 9227 fax 408 779 9208 service fax www velodyne com Service e mail service velodyne com Product e mail help velodyne com Technical e mail techhelp velodyne com W Printed on recycled paper 63 DPS1012 20FEB04

11. our new Velodyne subwoofer using the line level connections you should always use shielded phono cables There are many decent 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 noise problems When using speaker level connections use a decent quality speaker cable that mates well with the connectors at least 14 gauge Be very careful to avoid any loose or frayed strands that could result in a short causing a dangerous condition and possible damage to your unit Cables of extremely large size are typically not required Extremely large gauge wire may not properly fit in the binding posts resulting in a poor connection and possible short circuits True subwoofers operate at extremely low frequencies which are primarily omni directional While it is recommended that the subwoofers be placed on the same plane as the satellite speakers room and system conditions often dictate otherwise Keep in mind that frequency response and output level can be drastically influenced by placement depending on the acoustic properties of your listening room Typically the optimum location for a subwoofer is in a front corner of your listening room This location will usually offer the greatest output levels and optimum low frequency extension The worst location for a subwoofer is typically far away from any walls close to the center of your room and
