Congratulations on your purchase of a Velodyne CHT-Q subwoofer. This system represents the state-of-the-art in low frequency reproduction. Read and follow the instructions below to ensure safe and proper system operation. [. . . ] 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 70 Hz. Subwoofer Direct Subwoofer Direct is a setting on the low-pass crossover knob and will allow frequencies up to 120 Hz into the subwoofer. See below for a more detailed explanation of this feature. . www. velodyne. com CHT-Q Series User's Manual 8 C ro s s ov e rs 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 DigitalTM, DTSTM, THXTM) have a "subwoofer out" jack (sometimes labeled "LFE") 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 CHT-Q subwoofer, or simply setting one crossover to a higher frequency (such as 120 Hz) will restore maximum performance.

There are many high quality cables available today. It is recommended that you keep the length of cable as short as possible to avoid any potential noise problems. When using speaker level connections, use a high quality speaker cable that mates well with the connectors. Be very careful to avoid any loose strands or frayed wires that may result in a short, which may damage your equipment. Cables of extremely large size are not required due to the low current draw of this type of connection. Extremely large gauge wire may not properly fit in the terminals, resulting in a poor connection and possible short circuits. Usage This section addresses usage of your CHT-Q subwoofer. Remote Control The features of the CHT-Q remote control are listed below. NOTE: The CHT-Q remote can be attached magnetically to the back of the subwoofer in the upper left hand corner. · POWER -- This button forces your CHT-Q subwoofer unit into standby mode. The woofer will not play and the LED will turn off. The unit will remain in this mode until the POWER button is pressed again. power down) the unit, turn off the power switch on the back panel.
