Congratulations! 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. Note: Do not leave unit in direct sunlight or use in high humidity environments!!! Warning! To prevent fire or shock hazard, do not expose this product to rain or moisture. To avoid electrical shock, do not open the speaker enclosure or amp chassis cover.
Prepare for Installation Your new Velodyne subwoofer provides for a number of installation options. Read all of 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 to prevent possible damage. Placement The first step in installing your new CHT-Q sub is to determine where it will be placed in the room.
I n s ta l l a t i o n Inputs Your new subwoofer is equipped with speaker-level and line-level inputs. Use the LINE LEVEL jacks when connecting your subwoofer to a pre-amp, signal processor (such as LFE out), linelevel crossover, or receiver with pre-amp level outputs. When using the line level jacks, some receivers may not provide enough signal to have the unit’s auto-on feature operate properly. Additionally, this lack of signal may also cause the subwoofer to produce less output than it is capable of.
Phase Adjustment - 0°/90°/180°/270° This control allows you to change the phase of the subwoofer’s output signal 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 music playing, then depress the various phase switches on the remote control and listen for a change in mid-bass frequency output. The correct position will have a greater amount of apparent mid-bass frequency output.

CHT-8Q, CHT-10Q, and CHT-12Q Rear Panel Connections Figure 2 shows the controls and connections on the rear panel of the CHT-8Q, CHT-10Q, and CHT-12Q. Following are brief descriptions of the controls and connections described in Figures 2 and 4 and 5. More detail of these connections can be found below: (1) . SPEAKER LEVEL INPUT Terminals Connect these input terminals to the speaker output terminals of your amplifier or receiver.
(2) SPEAKER LEVEL OUTPUT Terminals Sends a crossed-over speaker-level signal to the front speakers. See below for a more detailed explanation of this crossover. (3) IR INPUT This is a connection that allows the utilization of a third party infrared remote sensor, such as Elan or Xantech, or an extended cable for placement closer to your other remote controlled equipment. This keeps you from awkward control angles using the infrared remote control.
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 crossover 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.
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 Digital™, DTS™, THX™) 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.

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. 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.
• LIGHT — If you wish, you can deactivate the numeric LED on your CHT-Q subwoofer by pressing the LIGHT button on your remote. To reactivate the LED, press the LIGHT button again. When the display has been deactivated, it will light only when you make adjustments to the subwoofer controls and then turn off again. • NIGHT — Night mode limits the maximum dynamic output of the subwoofer for late night listening or to be more considerate of close neighbors.
The following table indicates musical style and which preset is recommended for it.
R e s t o r i n g D e fa u l t s There is a feature that allows you to restore default settings for your CHT-Q subwoofer. By pressing presets in EXACTLY the following order on the remote, the unit will restore its default settings.
T roubleshooting and Service Before seeking service for your amplifier or subwoofer, please re-check all systems. Following is a simple troubleshooting guide to assist you. 1. 2. 3. 4. 5. Verify that the unit is plugged in and power outlet used is active. Is the power switch on? Is the unit receiving an input signal from your source? Have all controls (volume, crossover, phase, etc.) been properly set? If the unit has been running at high levels, one of the protection circuits may be engaged.
