Installation – Step-by-Step
9
.www.velodyne.com Digital Drive User’s Manual
Toensure a quick and flawless installation of your Velodyne Digital Drive unit, follow these
numbered setup instructions in their exact order.
SUBWOOFER CABLE CONNECTIONS
Make all necessary cable connections between the applicable subwoofer connector port and
your particular home electronics equipment in the following order:
1. Insert the detachable AC power cord into the 117V~, 60Hz, 15A power interface port on
the rear panel of your subwoofer. Plug the male end of the cord into a convenient wall outlet.
2. Provide signal to your subwoofer through one or more of the following connections (refer to
your receiver/processor owner’s manual for available inputs to the subwoofer):
a. LFE INPUT (RCA, the RED jack at location 11 on Figure 2) –This is the most common
input cable connection. Make a connection between this input and the LFE output or
the subwoofer output of your receiver or processor; OR
b. LFE INPUT (XLR, location 6 on Figure 2) –Make a connection between this input and
the balanced LFE outputs of your receiver or processor; OR
c. INPUT, LEFT and RIGHT (location 11 on Figure 2) –Make a connection between these
inputs and the stereo outputs of your receiver or processor; OR
d. SPEAKER-LEVEL INPUT (location 14 on Figure 2) –Make a connection between these
inputs and the left and right speaker connections on your receiver or processor.Make
this connection by either inserting speaker wire into the correct binding post terminals
or by removing the banana plug jack caps and inserting banana plug wireinto the jacks.
NOTE: Refrain from routing connections permanently at this time to accommodate subwoofer
room placement as described below.
3. Establish the line-level connection (optional). Connect 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 80Hz, 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.
AWord About Subwoofer Outputs
The Velodyne subwoofer is designed to operate using the full range audio signal for input when
using the digital built-in crossover.Most processors/receivers have a “subwoofer out” jack that
is internally filtered and designed to be used with a conventional amplifier and speaker. In some
rarecases, 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
internal crossover in either the processor or Velodyne subwoofer. In some installations, simply
setting one crossover to a higher frequency (such as 120Hz) will restore maximum
performance. To bypass the subwoofer’s internal crossover when the unit is being fed a low
pass signal from another crossover, refer to the SETUP instructions at step 14 (page 24).
Note: If not using an external crossover
,you should use the built-in crossover for
optimal performance.

10
.www.velodyne.com Digital Drive User’s Manual
4.Referring to Figure 2, Locations 5 and 8, connect the audio/video cable between your
subwoofer (EQ OUTPUT VIDEO/LEFT/RIGHT yellow, white, and red respectively) and your
electronics (receiver, processor, TV, etc.). Insert the color-coded cable plugs into the correct
EQ OUTPUT receptacle – the yellow plug into the VIDEO jack, the white plug into the LEFT
jack, and the red plug into the RIGHT jack. The opposite ends of this cable should be
connected to your receiver/processor. The yellow VIDEO cable goes to an available
composite video input (e.g. aux), and the white/red AUDIO (L&R) cables go to a
corresponding audio input. Consult your receiver/processor and/or TV owner’s manual for
more information.
NOTE: Make sure the audio output goes into your AUDIO system, not your TV! The subwoofer
will generate test tones used to match the subwoofer to your satellites and to correct for room
anomalies that need to be played over your main audio system.
5. Insert the XLR microphone cable’s 3-pin male plug into the MIC INPUT jack (location 7 on
Figure 2) on the back panel of the subwoofer. For DD-15 and DD-18 units, a microphone
jack is also located on the front of the unit for convenience.
6. Slide the microphone (male connector end first) down through the open, circular sleeve of
the tabletop microphone stand. Position this assembly at a desired listening position from
your subwoofer.
NOTE: The Digital Drive Accessory Kit includes a microphone stand adapter (1/2”-27 thread)
for use with professional mounting stands. Be sure to first remove the inner thread piece
(3/8”-16) before using.
7. Connect the XLR microphone cable’s female jack end with the male connector end of
the microphone.
8. Sheath the microphone pickup with the foam windscreen cover as a protection against dirt
and airborne contaminants.
AWord About Interconnect Cables
When installing your new Velodyne subwoofer using the line level connections, you should always
use shielded phono cables. There are many quality cables available today, most any of which
will work perfectly well. We do recommend that you keep the length of cable as short as
possible to avoid any potential noise problems.
When routing cables, try to keep them away from equipment that generates significant noise
such as industrial or digital equipment.
AWord About Connecting More Than One Subwoofer
If you are connecting more than one DD subwoofer to your system, you will connect them
together in a “daisy-chain.” Choose one sub for all the connections described below (we’ll call
this the “master” sub), and then connect an RCA jack from the THRU RCA jacks of the “primary”
to the input jacks of the “slave” sub. You will also need to obtain a “Mouse Extension” serial
cable (available at any computer store, from your Authorized Velodyne dealer, or from Velodyne
directly) and connect the RS-232 OUT port of the primary sub to the RS-232 IN port of the
secondary sub. Then, all runtime commands directed at the primary sub (such as volume) will
be communicated to the secondary sub automatically through the serial cable. If you have more
than two subs in your setup, simply continue the daisy chain from the secondary sub to the next
sub in the line (using both RCA and serial connections) and so on.

11
.www.velodyne.com Digital Drive User’s Manual
NOTE: When a DD subwoofer detects an incoming RS-232 command, it reverts to “Slave
Mode.” This means that the subwoofer will no longer accept IR commands. To reestablish
normal operations, remove the RS-232 cable and power cycle the unit.
Note that the daisy chain connection ONLY allows the woofers to communicate basic “run-time”
commands such as volume and preset. We recommend the following sequence when setting
up daisy-chained subs.
1. First, connect only the master sub to the system. Do not connect the thru or serial
cables at this time.
2. Establish the crossover, phase, and other settings EXCEPT the EQ on the master sub
(see setup steps 1 –17 starting on page 17). Note the low pass crossover, phase
and polarity settings, then save.
3. Connect the video out of the slave subwoofer, go to the settings screen, establish the
low pass crossover, slope, phase, polarity, and night mode settings from the master
subwoofer, then save settings. Repeat for each slave subwoofer in your system.
4. Connect the microphone to the slave subwoofer and use the “self-EQ” feature
(described on page 12) to establish room EQ for that subwoofer.
5. Repeat steps 3 and 4 for each slave subwoofer in your system.
6. Reconnect the video out to the master subwoofer, and reconnect the thru and serial
cables so that the master and slave subwoofer(s) are daisy chained.
7. EQ the primary subwoofer (see steps 8-25 starting on page 20). Self-EQ is NOT
recommended for the primary subwoofer.
8. Setup is complete!
AWord About Setting Up Your Receiver/Processor For Optimal
Subwoofer Performance
It is important that your receiver/processor (from now on we’ll refer to this as your “receiver” for
simplicity) be set up correctly to work in concert with your DD subwoofer. In the receiver’s “speaker
set up” menu you will enter the number of speakers and indicate whether or not you have a
subwoofer. In addition you will enter the speaker size, usually “large” or “small.” It is almost always
advantageous to use the “small” setting. Most full-range speakers use smaller woofers for the
bass section and typically do much better in the upper bass and lower midrange if relieved of deep
bass duties. Your DD subwoofer, with its 1250 Watt RMS amplifier, large magnet and voice coil,
and servo control, can play 80Hz and below moreaccurately, with more power and with lower
distortion than a full range loudspeaker can. This is often referred to as “bi-amping” a system.
Setting your speakers to “small” in your receiver also means the receiver’s bass management will
send bass to the subwoofer in all playback modes, 2-channel or surround.
When you choose “small” you activate the receiver’s crossover. Some receivers will offer crossover
choices. In this case a good rule of thumb is double the low number of the stated frequency
response of your main speakers. So if a speaker’s response is rated from 40Hz –18KHz, then
doubling the 40Hz low frequency number equals 80Hz. In this example 80Hz would be a good
crossover point. When in doubt, 80Hz is always a good starting point. Those that do not offer
choices normally crossover at 80Hz, which is an excellent crossover point, and is also the
THX™standard.
If you use this “small” speaker set up recommendation go into the DD’s “SYSTEM SETTINGS”
screen and turnthe DD’s crossover “OFF” (see page 26).

Subwoofer setup – Overview
12
.www.velodyne.com Digital Drive User’s Manual
BEFORE YOU BEGIN: Once the installation has been completed, note that you can use your
subwoofer without performing ANY of the setup steps below. Simply use the remote to set the
volume, and select the preset that most closely matches your listening material, and enjoy!
However, to reap the maximum benefits of Digital Drive technology, read on!
Special note for 230V users with video problems
For 230-volt Digital Drive subwoofers, the default video mode is NTSC video format. If your TV
is NTSC compatible, you will have no trouble with this mode. However, certain TVs (especially
older ones) may require PAL or SECAM video. To switch from NTSC to PAL/SECAM mode,
press the DOWN ARROW four times followed by RESET. The subwoofer will restart in
PAL/SECAM video mode. To revert back to NTSC, restore defaults by pressing 8-9-0while on
the cover screen.
SELF-EQ
To perform an abbreviated setup of your Digital Drive subwoofer using the self-EQ function,
position the microphone in your listening position and connect it to the subwoofer as shown in
the installation instructions. Then, press 3-2-1on the remote. The subwoofer emits 25
“sweep tones” that are detected by the microphone and then automatically EQs your subwoofer
accordingly. After the sweep tones are completed, the unit automatically saves settings and
returns to normal operation. Once the self-EQ process starts, pressing the RESET button can
interrupt it.
Caution: Self-EQ resets all EQs for all presets to their default values. DO NOT use the self-EQ
featureif you plan to adjust the DD subwoofer manually as described below.
ON-SCREEN Setup
This section describes adjusting the onscreen settings of your Digital Drive subwoofer. You will
be performing all the setup functions using the buttons of your Velodyne-supplied remote control
and seeing the results on your TV screen. Words in all uppercase letters in the setup
instructions (e.g., SELECT, MENU, etc.) identify the specific remote button to be pressed or
selected, or the field on the screen you should be paying attention to. Remember to point the
remote control at the subwoofer, not your TV!
Use the UP, DOWN, RIGHT, and LEFT directional arrow buttons that surround SELECT to
navigate the fields of the setup screens. Settings are typically changed using the SELECT key,
followed by the UP and DOWN arrow keys. Alternatively, the SET +/- buttons can be used to
change settings. A screen field highlighted in reverse video indicates your current location on
the screen. Holding down the UP, DOWN, RIGHT, or LEFT arrow keys causes the remote to
repeat and you can then rapidly move through fields to arrive at the desired one. You should
be able to perform most of the setup process by using the four arrow keys and the
SELECT button.
Following is an overview of the screens you will be using to set up your
Velodyne Digital Drive subwoofer.
