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.

Crossov ers
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.

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.
