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. Unpack the system carefully and use the following guidelines in order to find the best  
room placement option.  
True subwoofers operate at extremely low frequencies which are primarily omni-directional.  
Keep in mind that frequency response and output level can be drastically influenced by  
placement, depending on the acoustic properties of the listening room. To obtain optimum  
output from your subwoofer, try placing it within a foot of a corner. This location will offer the  
greatest output levels and optimum low frequency extension. If at all possible, your subwoofer  
should be placed along a wall. The worst location for a subwoofer is typically far away from any  
walls and close to the center of your room. Avoid these locations when possible. When using  
a pair of Velodyne subwoofers in stereo, it is preferable to feed each subwoofer with one  
channel and place each subwoofer near the satellite of the same channel.  
Depending on the size and type of furnishings in the room, perfect placement may not be  
possible. Finding the best location within your environment will likely require some  
experimentation. We suggest you experiment with the location during setup to find what sounds  
best to you when seated in your typical listening position.  
Regardless of where you install your Velodyne subwoofer, it must remain in an upright position  
(woofer facing forward). Using, shipping or storing the subwoofer in any other position for an  
extended period of time may result in damage to the unit not covered by warranty.  
Caution!  
This subwoofer has electronics built into the cabinet. Do not place the cabinet next to sources  
of heat such as furnace registers, radiators, etc. Do not place the unit near sources of  
excessive moisture such as evaporative coolers, humidifiers, etc. The power cord should be  
routed in such a way that it will not be walked on, pinched or compressed in any way that could  
result in damage to the insulation or wire.  
Your Velodyne CHT-Q subwoofer is NOT magnetically shielded. Should you find it necessary to  
use it with an older CRT monitor or TV, keep it at least two feet from the monitor. Experiment  
for correct distance by minimizing distortion of the picture and colors.

Ins tallation  
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), line-  
level 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.  
To alleviate this condition, we recommend the following steps:  
1) If using line level jacks, BOTH THE LEFT AND RIGHT INPUT SHOULD ALWAYS BE USED –  
never use just the left or just the right input. If using line level connections from a  
preamp or signal processor, use both Left and Right inputs from your preprocessor or  
preamp and connect them to the Left and Right inputs on your subwoofer. (See figure 4  
on page 10.)  
2) If using a receiver with LFE out, be sure the LFE channel is sending adequate signal to the  
subwoofer. The subwoofer’s default volume setting is 30 on a 1-80 scale (roughly 1/3  
volume). Adjust the LFE channel on your receiver or processor to achieve the desired bass  
output. See your receiver or processor’s owner’s manual for more information. (See figure  
5 on page 11.)  
Volume Control  
This control allows you to balance the output from the subwoofer to the main speakers in your  
system. This control should be set to achieve similar output levels from both the main speakers  
and subwoofer when listening to music. The default volume setting is 30 on a 1-80 scale.  
Warning:  
Some manufacturers preset their receivers with the Sub-Out channel signal at a minimum level.  
It is very important to verify that your receiver Sub-Out channel is set to the same output level  
as your front right and left channels. Refer to your receiver manual for the individual channel  
level adjustment procedure. If your receiver Sub-Out channel is set too low, the subwoofer may  
appear to have a weak output, it may sound noisy or distorted, and the Auto On/Off feature  
may not operate properly.  
Low-pass Crossover - 40 to 120 Hz  
All inputs sum the left and right channels together, with the resulting signal passing 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. 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 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. The default crossover setting is  
80 Hz. With larger speakers, you may want to set this even lower, for example 70 Hz.

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.  
If the settings sound similar, we recommend the “0” position. See the remote control section  
for more information.  
Auto Turn on Function  
The subwoofer will turn itself on automatically when an audio signal is present. If no signal is  
present for approximately eight minutes, the unit will switch to standby mode (blank LED). While  
in standby mode, your subwoofer will draw very minimal power. Your sub is shipped in the  
“Always On” position. In order to activate the circuit, change the switch to “Stand-by”.  
Warning:  
If the Sub-Out channel signal level from your receiver is too weak, this feature will not operate  
properly and shut the subwoofer off while you are listening to it. To correct this, see the  
VOLUME CONTROL section on previous page.

(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.  
(4) LINE OUTPUT  
Connect these jacks to the LINE IN preamp input to use the DEQ-R’s internal high  
pass crossover. The signal fed from these connectors is rolled off below 120 Hz.  
LINE INPUT/LFE  
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 (not included) and feed the signal into both “R” and “L” inputs.  
(5) AUTO ON/OFF Switch  
Use this switch to select between “stand-by” mode (woofer shuts off after eight  
minutes) and “always on” operation.  
(6) VOLUME Control  
This control allows you to balance the output from the subwoofer to the main  
speakers in your system. This control should be set to achieve similar volume level  
from between both the main speakers and subwoofer. When pressing volume up  
or down, set the level while watching the LED display for reference.  
Note: Volume is also controllable by using the supplied remote. When defaults are restored,  
the default is 30 out of 80.  
(7) LOW-PASS CROSSOVER  
Use this knob to select the frequency above which you wish to cut off the signal to  
the subwoofer. When the knob is turned all the way to the left, the Subwoofer  
Direct feature is invoked and the subwoofer plays all frequencies up to 120 Hz.  
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 connecting 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.  
Note:  
Do not use both the RCA/Phono “INPUT” connections and “SPEAKER LEVEL INPUT”  
connections simultaneously.

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.  
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.

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. 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.  
(Refer to Figure 4 Line-Level Subwoofer Connection Diagram and Figure 5 Speaker-Level  
Subwoofer Connection Diagram, pages 10 and 11 for connection diagrams.)

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. 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. To fully deactivate (i.e. power down) the unit,  
turn off the power switch on the back panel.  
• MUTE — This button mutes the subwoofer’s output. The LED  
on the sub will show 00 if the unit is muted. To unmute the  
subwoofer, press the MUTE button again and the original  
volume setting shows on the LED.  
Figure 6: CHT-Q Remote.  
• EQ — This button automatically equalizes the subwoofer’s output so that it sounds best for  
its position in the room. To use this feature, remove the grille and plug the supplied  
microphone into the Mic-In jack on the front baffle of the sub and place the mic in your  
preferred listening position. Then press EQ on the remote for about 2-3 seconds. The  
subwoofer emits 12 “sweep tones” that span the frequencies between 20 and 150 Hz. The  
LED displays “AU” during the Auto-EQ process. After the sweeps are complete, the unit saves  
its EQ settings and returns to normal operation. To prevent accidental invocation of the EQ  
feature, you must hold down the EQ button for 2-3 seconds before the EQ sweeps begin. If  
the mic is not plugged in, the subwoofer sweeps twice then reverts back to normal functioning  
without changing any EQ settings.  
• PHASE — These buttons allow you to optimize the subwoofer’s bass performance relative to  
the speakers and your listening position. Play some bass heavy music. While listening, push  
one of the four phase buttons, listen for a few moments, and then press the next phase  
button. In most installations, one of the four button positions will offer an audibly better blend  
of subwoofer and speakers. The LED will show the phase selected by showing “PH” followed  
by the phase number: 0, 90, 180 or 270.

• 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. Press the night button to turn the  
night mode feature on or off. Activation of night mode causes “n” to appear briefly on  
the display. When night mode is deactivated, the display shows “n off” and then returns to  
normal function.  
• VOLUME CONTROL — This control allows you to balance the output from the subwoofer to  
the main speakers in your system. This control should be set to achieve similar volume level  
of both the main speakers and subwoofer. When pressing volume up or down, the volume  
level is shown on the numeric LED on the front panel.  
WARNING: Some manufacturers preset their receivers with the Sub-Out channel signal at a  
minimum level. It is very important to verify that your receiver Sub-Out channel is set to the  
same output level as your front right and left channels. Refer to your receiver manual for the  
individual channel level adjustment procedure. If your receiver Sub-Out channel is set too low,  
the subwoofer may appear to have a weak output, it may sound noisy or distorted, and the  
Auto On/Off feature may not operate properly.  
Note: The volume can also be adjusted via the buttons on the back panel of the subwoofer.  
These buttons have the same effect as pressing the up and down volume buttons on  
your remote. The unit comes preset from the factory with the volume set at 30 out of 80.  
• PRESETS There are four listening presets, consisting of Movies, R&B – Rock,  
Jazz – Classical, and Games. The presets provide the following characteristics for  
bass reproduction:  
Movies:  
Maximum output and impact for explosions and other  
action adventure movie content.  
R&B – Rock:  
Provides the driving bass found in today’s rock music.  
Jazz – Classical: The tightest, cleanest, lowest distortion bass. The flattest frequency  
response of the four presets.  
Games:  
Maximum loudness available for the impact of video games.

Preset 1: Movies  
When you press the presets in the above order, the front LED will display “P3” indicating that  
you have restored defaults. The unit’s volume is reset to level 30 out of 80.  
Care of Your Subwoofer  
Your Velodyne subwoofer does not require any regular maintenance. Normal dusting or cleaning  
of the surface for appearance purposes is all that is required. We suggest you avoid any harsh  
detergents or chemicals when cleaning the cabinet. Abrasives, detergents, or cleaning  
solutions may damage the finish on the cabinet. We recommend using only a damp cloth to  
clean the cabinet.  
During normal conditions, your new subwoofer may be left on continuously without any  
problems. Using the Auto on/off function, the unit will automatically turn on the unit when a  
signal is present at the inputs and turn off after several minutes when there is no longer any  
signal at the inputs.  
Protection Circuitry  
Your new subwoofer is equipped with circuitry to provide maximum performance with  
greatest reliability.  
The unit is protected against:  
1) Overheating the amplifier.  
2) Excessive drop in power line voltage.  
If either of the above should happen, you should reduce the volume setting or shut the unit off  
until normal operating conditions return. You may also want to plug the unit into a different wall  
outlet, as dropping power line voltage will be most noticeable under strenuous conditions and  
may result in the unit shutting down intermittently.

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. Verify that the unit is plugged in and power outlet used is active.  
2. Is the power switch on?  
3. Is the unit receiving an input signal from your source?  
4. Have all controls (volume, crossover, phase, etc.) been properly set?  
5. If the unit has been running at high levels, one of the protection circuits may be engaged.  
Has the amplifier overheated?  
6. Has the power button been depressed on the remote?  
7. Make sure binding posts are tightened.  
8. Is the remote non-responsive? We recommend replacing the batteries in the remote.  
If the protection circuitry is active, the unit may cycle on and off until operating parameters  
return to normal. Under more serious conditions, the unit may shut off completely. Normal  
operation should return upon cooling, but you may be required to turn the power off and then  
on again to reset the unit.  
The following conditions require service by a qualified technician:  
1. The power cord has become damaged  
2. The unit does not appear to operate normally or exhibits a marked  
change in performance  
3. The unit has been exposed to water  
4. Some part of the chassis or circuitry is physically damaged
