User manual VELODYNE CHT-15Q DATASHEET

[. . . ] Retain Instructions -- The safety and operating instructions should be retained for future reference. Heed Warnings -- All warnings on the subwoofer and in the operating instructions should be adhered to. Follow Instructions -- All operating and use instructions should be followed. Water and Moisture -- The subwoofer should not be used near water -- for example, near a bathtub, washbowl, kitchen sink, laundry tub, in a wet basement, near a swimming pool or the like. [. . . ] When pressing volume up or down, the speed at which the power light blinks indicates subwoofer volume - the faster the blinking, the louder the unit plays. (3) AUTO ON/OFF Switch Use this switch to select between auto-on (active) and constant on (inactive) operation. (4) LINE OUTPUT Connect these jacks to the LINE IN preamp input to use the CHT-R's internal high pass crossover. (5) LINE INPUT/LFE Input Connect these jacks to the LINE OUT preamp output, LFE output, or subwoofer output jacks of your receiver/processor. If using the LFE output from your receiver or processor, plug the single cable into the "L" ­ LFE input or, for more signal, use a "Y" connector and feed the signal into both "R" and "L" inputs. continued. . 4 (6) HIGH PASS CROSSOVER Switch This switch selects the frequency for the high pass crossover. Smaller speakers with limited low frequency output may perform better using the higher 100 Hz setting that will reduce the low frequencies sent to them. Larger speakers with greater low frequency output may be able to handle the 80 Hz setting without strain. (7) SPEAKER LEVEL INPUT Terminals Connect these input terminals to the speaker output terminals of your amplifier or receiver. If you use this method of connection, when you go to the receiver speaker set up menu, make sure you select the large speaker option. (8) SPEAKER LEVEL OUTPUT Terminals Sends a crossed-over speaker-level signal to the front speakers. When using a single RCA sub out from the processor, it does not matter which line level input (L/R) is used. Interconnect Cables When installing your 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 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. Extremely large gauge wire may not properly fit in the binding posts, resulting in a poor connection and possible short circuits. Placement 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, 7 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 near an opening or door way. [. . . ] Abrasives, detergents, or cleaning solutions will damage the finish on the cabinet. Use a soft cloth with a good quality furniture polish to clean the hand-rubbed, black lacquer, painted top. 12 During normal conditions, the subwoofer may be left on continuously without any problems. If you plan to leave the unit unused for an extended period of time, we recommend that you turn off the unit by the master power switch on the rear panel. Troubleshooting and Service Before seeking service for your subwoofer, please re-check all systems. Have all controls on subwoofer (volume, crossover, phase, etc. ) been properly set? [. . . ]
