For added low frequency performance the amplifiers are equipped with a selectable
6dB-12dB bass boost @ 45Hz
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
WDX300.4, WDX400.4 and WDX800.4 also offers independent 12dB per octave High
Pass and Low Pass X-Over Network.

The WDX1K, WDX2K, WDX3K and WDX5K are equipped with a variable 24db slope
Lowpass crossover network and a 24db slope subsonic lter. 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 ne tune the subwoofer
enclosure depending on vehicle location.

( 4 Channel: WDX300.4, WDX400.4, WDX800.4 )
The WDX300.4, WDX400.4 and WDX800.4 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
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.
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.
