this control allows the amplifier gain to be controlled to match the source
unit.
9. 2CH/4CH Signal Pass-Through Selection Switch
For F300.4 set 2CH/4CH switch to "2CH" when running two separate
RCA/AUX cables. When running a single RCA/AUX cable set 2CH/4CH
switch to "4CH" to allow signal to pass through to all channels.
10. MODE
LPF: Set the MODE SWITCH to the LPF position when the amplifier is used to drive a
FULL: Set the MODE SWITCH to the FULL position when the amplifier is used to drive full-
11. High Pass Filter
This controls the high pass crossover point for the speaker outputs. This
crossover, when selected, will attenuate the frequencies below the
crossover point with a slope of -12dB per octave The crossover point is
adjustable from 25-250Hz. This filter reduces unwanted lower frequencies
from being played through the speaker(s).
Adjusting the Amplifier
1. Disconnect the negative battery post and secure it to something so
accidental re-connection does not occur during the installation process.
2. Run all wires needed for the amplifier to work correctly. Do not attach the
fuse in the fuse holder by the battery until all wires have been plugged into
the amplifier.
3. Turn the amplifiers gain and boost all the way down (counter clockwise).
4. As a good "starting point" set phase to 0, subsonic and other adjustment
knobs all the way down (counter clockwise) and mode switches to the
correct MODE being used.
5. Attach the recommended fuse

subwoofer system. The frequencies above the crossover point will be attenuated
at -12dB/octave. Adjust the crossover frequency by rotating the LPF knob to the
desired frequency ranging from 50-150Hz. See #5 below for more details.
range speakers and/or components that come with their own crossover. The full
frequency bandwidth will be output to the speakers without high or low frequency
attenuation.
