The mini D amplifier series has a built in pre-amplifier that allows users to custom
design the frequency response and shape to their requirement. The pre-amplifier
stage includes the following features:
Bass Boost -available on the D2000 and D2500 models only
The bass boost allows you to select the center frequency that you want to
boost as well as the quantity. For most application, the best setting is at %
turn (2 o'clock position).
Variable Subsonic Filter
Subsonic filters are often used to protect speakers from harmful low
frequencies and DC voltage. Often clipped low frequencies could have
the same effect as that of DC input. The best setting for most system is at
30Hz Highpass.
LPF (Low Pass Filter)
Often mistaken as crossover, the LPF is used to filter out unwanted mid
and high frequencies, leaving the woofer to response to low frequencies.
For most subwoofer application, the best crossing point is about
% turn (2
o'c1ockposition).
Gain Control
Gain control regulates the amplifier'ssensitivity to match the signaIoutput
voltage of the audio source/head unit. It is not a volume control. The
D amplifiers have gain controls that are extremely sensitive and therefore,
should be adjusted with caution. When set at MIN, it will need 4V to clip
these amplifiers. But with a mere
0.5V.

receives signal from the master amplifier and should only be used when the
amplifier is the slave amplifier (ali functions of the slave amplifier will be
adjusted by the master amplifier). The BRIDGE OUT sends signal to the
slave amplifier and should only be used when the amplifier is the master
