Bass Boost

The DB Drive Euphoria Mono amplifiers feature a variable Bass Boost gain centered at 45Hz thatenables the user to adjust the amount of bass boost needed to achieve the desired amount of lowend 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.

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 ampliers (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 SettingsThe F475 and F4100 ampliers 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 congured in many dierent 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 amplier 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.
