PREPARE FOR INSTALLATION
your new Velodyne subwoofer provides for a number of installation options. Read all of the installation
information below in order to deter mine which installation option is best for your system. Remember to perform
all installation procedures with system power turned o to prevent possible damage.
Placement
The rst step in installing your new eq-Max sub is to determine where it will be placed in the room. Unpack the
system carefully and use the following guidelines in order to nd 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 inuenced 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 oer 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, or close to a doorway or opening into another 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 nd what sounds best to you when seated in your typical listening position.
For more information on placement, please refer to Velodyne’s Subwoofer Placement Recommendations Guide.
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, humidiers, 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 eq-Max subwoofer is NoT magnetically shielded. Should you nd 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.

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 or sub 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 gure 4 on page 11.)
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 bassoutput. See your receiver or processor’s owner’s
manual for more information. (See gure 5 on page 12.)
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 amplied. The crossover control allows you to adjust the upper limit of the
subwoofer’s frequency response from 40 to 135 Hz. The subwoofer’s response will begin rolling o 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/amplier. 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 overall bass energy at
all frequencies. If the settings sound similar, we recommend the “0” position. See the remote control section for
more information.for more information.
