Installation Your new subwoofer system provides for a number of installation options. Read all the installation information below in order to determine which installation option is best for your system. Remember to perform all installation procedures with system power turned off. Inputs Your new subwoofer is equipped with both speaker-level and line-level inputs. Use the RCA/Phono type "INPUT" jacks when connecting your subwoofer to a pre-amp, signal processor, or line-level crossover. The "S

Subwoofer Direct A bypass switch is also provided if you wish to use an external crossover. If you are not using an external crossover, we recommend that you use the one provided within the unit for optimum performance. Phase adjustment- 0˚/180˚ This control allows you the "reverse" the phase of the subwoofer's output signal 180˚ to correct for any possible mismatch and resulting cancellation between the subwoofer and your main speakers/amplifier. To adjust, simply listen to the system with mus

Line-level connection Figure 1 shows connection to a pre-amplifier's main outputs and returning them to your amplifier inputs. When installed in this fashion, your satellite speakers will be crossed over at 80/100Hz (or 85Hz for CHT-8/-10) which removes the lower bass from your amplifier and speakers, enabling them to do a better job reproducing high frequencies. By utilizing this method, you will have a bi-amplified system, gaining improved power and headroom for your system. Figure 1: Install

In these installations, you may bypass the internal crossover in either the processor or the Velodyne subwoofer. In some installations, it may be beneficial to have a steeper ultimate crossover slope. To do this you can use both your processor's crossover and the one internal to the Velodyne sub. You should stagger the frequencies (i.e., 120Hz sub, 80Hz processor) for best results. To bypass the subwoofer's internal crossover when the unit is being fed a low pass signal from another crossover

Caution!!! To avoid damage to your main amplifier, be sure to maintain correct polarity when making all connections. Red (positive) to red, and black (negative) to black. Be sure that all connections are tight, and that there are no loose strands or frayed wires.

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, 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 the listening room. Typically, the optimum location for a subwoofer is tucked away in a corner of your list

Troubleshooting and Service Before seeking service for your subwoofer, please re-check all systems. Following is a simple troubleshooting guide to assist you. 1. Verify unit is plugged in and power outlet used is active. 2. Is power switch on? 3. Is auto turn on/off set properly? 4. Is unit receiving an input signal from your source? 5. Have all controls on subwoofer (volume, crossover, phase, etc.) been properly set? 6. If unit has been running at high levels, one of the protection circ

"The CHT-10 hit these beats with a natural attack and decay and a tonality that you can't always expect from a sub at this price." - Chris Lewis Home Theater/February 2003 "It delivered room-shaking bass and dramatically demonstrated the effectiveness of a single subwoofer placed to one side of the room." - Julian Hirsh Stereo Review, January 1997 "If you know subwoofers, you know about Velodyne." - Corey Greenberg Home Theater Technology/February 1995 Other Velodyne Subwoofer Products: Digital
