In HIGHPASS mode, the dashboard, door and rear shelf speak-
ers (usually between10 and 16 cm in diameter) – which do
not give you strong bass reproduction anyway – will only be
playing in the midbass and mid/high frequency range. This
so-called highpass filtered or HPF amplification mode also
puts less electrical and mechanical 'strain' on your coaxials
and component speaker systems, resulting in an increased
power-handling capacity.
In LOWPASS mode the respective speaker output will only re-
ceive low-pass filtered (LPF) signals resulting in the subwoofer
only playing in the low-end bass frequency range without any
unwanted 'smearing' into the mid/high frequencies.

Before you can effect the respective input sensitivity / level
adjustments (GAIN) you first have to select the system ap-
propriate crossover frequencies for all speakers connected.
For best results all crossover settings should usually be played
by ear.
Do not forget to set the amplification mode switches into
the required position, i.e. HigHPASS or lOWPASS! Any fre-
quency setting on the filtering controls will be inactive if the
amplification mode switch remains in position FULL!

COnTrOlS & ADJUSTmEnTS
Sequence of Adjustments
Depending on amplifier type (2-channel or 4-channel), am-
plification mode (fullrange, highpass or lowpass) and con-
necting mode (stereo or mono bridged) only parts of the
adjustments described in this manual section are applicable
to your individual car audio system.
In case you are using your new amplifier(s) in a multi-channel
amplifier system with highpass-filtered front and/or rear satel-
lites and/or a lowpass-filtered subwoofer, we recommend you
to read the complete section "Controls & Adjustments" before
you start adjusting any of the frequency or level controls.
Active Highpass and lowpass Filtering
The AXTON models A2100X and A4050X do not only offer
conventional fullrange amplification: You also have the choice
of highpass or lowpass amplification mode, enabling you to
drive your car audio speakers in the specific frequency range
where they will perform best.
