A Word About Interconnect Cables; A Word About Connecting More Than One Subwoofer - Velodyne DIGITAL DRIVE SERIES User 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.

A Word 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.

A Word 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.
