AMPLIFIER SETTINGS

Input Level

These amplifiers have level adjustments to allow for easy integration with any source unit.
The input sensitivity can be adjusted from approximately 200mV to 5V. Refer to Testing the
System and Adjusting the Sound of the System sections of this guide for detailed instruc-
tions on setting the gain.

Internal Crossover Configurations

The crossover section of these amplifiers is continuously variable and extremely flexible.
This circuit is designed to optimize the performance of WCC subwoofers in all types of
enclosures.
When using WCC loudspeakers, minor deviations from the recommended frequency ranges
can provide superior results depending on your speaker locations and your vehicle acoustics.
Setting crossover frequencies higher than recommended will not cause damage and may
provide superior sonic results depending on your system's performance goals. Refer to your
loudspeaker owner's manual for assistance in choosing the proper crossover frequencies for
your system.
WARNING! DO NOT set crossover frequencies lower than the speakers recommended
operating range. This can cause driver failure that is not covered by the man-
ufacturer's warranty.

Low-Pass Crossover

When the switch is to the middle (OFF position), the low-pass crossover is bypassed. When
the switch is in the left (LPF position), the low-pass crossover is active with a 2nd order (12dB
per octave) slope. The low-pass crossover is continuously variable from 50Hz to 300Hz.

High-Pass Crossover

NOTE: Not applicable to the 5001 and 8001 models.
When the switch is to the middle (OFF position), the high-pass crossover is bypassed. When
the switch is to the right (HPF position), the high-pass crossover is active with a 2nd order
(12dB per octave) slope. The high-pass crossover is continuously variable from 50Hz to
500Hz. Additionally, boost can be added at the high-pass crossover frequency for improved
bass output while still protecting the woofer from excessive excursion.
WARNING! Maximum boost can potentially cause woofer damage due to over-excursion.

Fine Tuning the Crossovers

The low-pass and high-pass crossover sections are each marked at four frequency points for
ease of system adjustment. The low-pass crossover section is marked at 50Hz, 100Hz, 300Hz,
400Hz, and 500Hz. The high-pass crossover section is marked at 20Hz, 33Hz, 90Hz and
150Hz. Specific crossover points can be chosen based on the recommended operational
bandwidth of your speakers.
