CROSSOVER CONTROLS
Crossovers are groups of individual electronic
filters which allow only certain frequency
ranges to pass through them by attenuating
frequencies outside the selected range. These
filters allow the user to specify what frequency
range will be sent out of each channel section
of the amplifier. This, in turn, allows each
speaker system to only reproduce a range of
frequencies it is well-suited for, resulting in
reduced distortion and improved fidelity.

AMPLIFIER LOW-PASS FILTER
The 600/1v3 employs a sophisticated, state-
variable, low-pass active filter for its internal
channel. This feature is designed to attenuate
frequencies above its filter frequency, so that the
system’s subwoofers do not reproduce any audible
midrange content.

Tuning Hint
:
A trunk mounted sub whose output
has to "fight" through a rear deck or a back seat
often benefits from the 12 dB/octave slope which
lets more upper bass content pass through. A sub
that fires directly into the listening environment
is more likely to benefit from a 24 dB/octave slope.

You should always listen to the system carefully to
determine the best choice as vehicle acoustics and
other factors play a big role in choosing the most
appropriate filter slope.

The output of the amplifier will decrease
for a given input voltage when the “Input
Range” switch is placed in the “High” position.
Conversely, the output will be higher with
the switch in the “Low” position. While this
may sound counter-intuitive, it is correct
as described.
