DB DRIVE warrants any products purchased in the U.S.A.
from an authorized DB DRIVE dealer. All products are warranted to be
free from defects in material and workmanship under normal use and
service for a period of (1) year when the unit installed by an authorized
DB DRIVE dealer. Non-authorized dealer installed products carry a (1)
year parts and labor limited warranty. This warranty applies to the original purchase only.
DB DRIVE will either repair or replace (as its option) any unit
that has been found to be defective and under warranty provided the
defect occurs within:
One (1) year if purchased through an authorized DB DRIVE dealer.
This limited warranty does not extend to units that have been
subjected to misuse, abuse, neglect, or accident. Products that in DB
DRIVE’s judgment shows evidence of having been altered, modified,
or serviced without DB DRIVE’s authorization, will be ineligible under
this warranty.
To obtain warranty service please contact your retailer or see
our website www.dbdrive.net for more details.
All warranty claims must be handled directly through the
authorized DB Research dealer they were originally purchased from.

Bass Boost
For added low frequency performance the amplifier features selectable 45 Hz bass boost
EQ for both front and rear channels.
These amplifiers feature a high pass and low pass crossover for both the front and rear
channels. Both crossovers can be adjusted to the same for same setting function so that
the output is the same on all channels.

SIGNAL CONNECTIONS
To make these connections, we recommend high quality RCA cables, which are available
at your local car audio retailer. Run signal wires away from electrical wires to avoid possibility of induced noise from the car’s electrical system (i.e. popping noises or engine noise).
SPEAKER CONNECTIONS
(PRO2.6K, PRO3.6K)
Make the speaker connections using speaker wire that is at least 16
gauge or heavier.
As with any audio component, proper phasing of the amplifier and speakers is essential
for strong bass response. When connecting, make sure that positive (+) from the amplifier
is connected to the positive (+) of the speake

Filter Selection for Channel 1 & 2
The DB Drive amplifiers are equipped with built-in variable crossover networks allowing
you to select the crossover mode (i.e. Low-Pass/Full/High-Pass or On/Off) and the
desired crossover point. For example if you wish to drive a pair of subwoofers, you can
select the “Low Pass” setting on the amplifier to filter out high frequencies. This will send
only low frequencies to your subwoofers (see example settings below). The cross-over
point should be determined by the speakers operating range. Please refer to speaker
manufactures recommended crossover point.
The
gain sensitivity control for the DB Drive amplifier is located on the side panel. This
gain control has been included to allow adjustment to properly match the output of the
radio. This is one of the most misunderstood adjustments. By rotating the control in the
clockwise direction, the amplifier’s input will become more sensitive and the music will
play louder. This is not a volume control and you will not get more power out of the
amplifier in the
maximum position! It may seem to deliver more output, but actually the
system is only playing louder faster as you turn the volume control on the radio. Ideally,
to properly level match the system the goal is to achieve maximum output from the
amplifier without distortion at about ¾ of the volume control.
To determine if the
amplifier’s gain is set properly, turn the system on and slowly
increase the volume control. You should be able to use about ¾ volume before the
system gets loud but not distorting. It is very important when making these adjustments
that you do not over drive the speakers (at point of distortion) this will cause permanent
damage to the speakers. If you are unable to achieve ¾ volume before distortion you will
need to adjust gain control (in this case you would reduce the gain). The gain controls
should be adjusted very slowly. It may help to have another person to assist you by
adjusting the gain controls while you listen for distortion.
