Bass Boost
The DB Drive Euphoria Mono amplifiers feature a variable Bass Boost gain centered at 45Hz that
enables the user to adjust the amount of bass boost needed to achieve the desired amount of low
end response from the subwoofer system.
The DB Drive Euphoria 4 channel amplifiers (F475 & F4100) feature a variable 12dB
slope High Pass crossover for channels 1 and 2. Channels 3 and 4 feature a selectable 3
way 12dB Variable crossover that enable the user to select High Pass, Band Pass or Low
Pass settings.

( Mono: M750, M1500, M2250, M2750)( 4 Channel: F475, F4100 )
The M750, M1500, M2250 and M2750 are equipped with a variable 24db slope
Lowpass crossover network and a 24db slope subsonic lter. The mono amps also
feature a variable 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.
The DB Drive Euphoria 4 channel ampliers (F475 and F4100) feature a 12db Slope crossover
network. Channels 1 and 2 can be used in the High pass setting or full range and channels 3 and
4 feature a selectable 3 way crossover system that can be used in High pass, Bandpass or low
pass settings.
Adjustments and Settings
The F475 and F4100 ampliers are equipped with a variable crossover network that allows you to
select the crossover mode (Highpass—Full Range) and desired crossover point for channels 1
and 2. With a High Pass range between 50Hz and 4 KHz, channels 1 and 2 can be used with a
component tweeter or any type of full range speaker requiring High Pass ltering. Channels 3
and 4 allow you to select between a 3 way completely variable High pass Bandpass or Low pass
setting that can be congured in many dierent ways allowing the user set up the perfect audio
system.
For example if you wish to drive a pair of subwoofers on channels 3 and 4 in the bridged mode,
you can select the LP switch settings on the amplier to lter out the high frequencies. You will
then need to adjust the Lowpass control to the desired frequency setting. This will only send low
frequencies to your subwoofers. If you wish to use the Bandpass crossover lter you must set the
x-over push button switch settings to BP. Once the BP switch setting is selected you will use both
the Lowpass and Highpass controls to lter out the unwanted low and high frequencies to create
the desired Bandpass lter. (The Bandpass crossover is available on only channels 3 and 4) To use
the Highpass lter select the x-over push button switches to the HP setting, this will lter out any
unwanted low frequencies.
