FEATURES AND BENEFITS
The DB Drive WDX amplifiers includes built-in variable crossovers. The crossover features a variable frequency selection for precise low pass filtering for all mono amplifiers. The WDX300.4G2, WDX400.4G2 and WDX800.4G2 also offers independent 12dB per octave High Pass and Low Pass X-Over Network.
Bass Boost
For added low frequency performance the amplifiers are equipped with a
selectable 6dB-12dB bass boost @ 45Hz

BUILT-IN CROSSOVER
4 Channel: [ WDX300.4G2, WDX400.4G2, WDX800.4G2 ] The WDX300.4G2, WDX400.4G2
and WDX800.4G2 amplifier allow you to select the crossover mode (High-Pass,
Full Range or Low Pass / Band Pass) and desired crossover point for channels
1-2 and 3-4.
For example if you wish to use a 2-way loud speaker on channels 1-2, simply
set the crossover switch to HPF and adjust the frequency seng to the desired
HPF seng to block out any unwanted low frequencies.
If you wish to run a subwoofer on channels 3-4, simply set the crossover
switch to LP/BP. You must adjust the HPF frequency seng to 50Hz and the LPF
frequency seng to the desired Low Pass seng to block out any unwanted high
frequencies.
If you wish to run a component midrange on either channels 1-2 or 3-4 set the
crossover switch to LP/BP. Then use both HPF and LPF frequency controls to
create the desired band pass frequency range.
THESE SETTING CAN BE USE ON CHANNELS 1-2 OR 3-4 INDEPENDENTLY OR FOR ALL
CHANNELS

ADJUSTMENTS AND SETTINGS
( WDX1KG2 – WDX2KG2 – WDX3KG2 – WDX5KG2 ) The WDX1KG2, WDX2KG2, WDX3KG2 and
WDX5KG2 are equipped with a variable 24db slope Lowpass crossover network and
a 24db slope subsonic filter. The mono amps also feature a Selectable Bass
Boost EQ is set at 45Hz. In some subwoofer enclosure installations it may
necessary to use the Phase Shift feature. The Phase Shift button sets the
Subwoofer signal between 0 degree setting and 180 degree settings. This will
also allow you to fine tune the subwoofer enclosure depending on vehicle
location.
REMOTE BASS CONTROL MODULE
( WDX1KG2 – WDX2KG2 – WDX3KG2 – WDX5KG2 )
Before connecting the remote, it will be necessary to find a mounting location
that will be easy to access for adjustment. Once you select your mounting
location, your mounting location, you will need to run the control wire from
the remote to the remote to the amplifier. To avoid possibility of induced
noise from the car’s electrical system ( i.e. popping noises or engine noise
), run the cable from the remote to the amplifier away from the car’s
electrical wiring.
