Adjusting and Tuning is a critical step
in
optimizing the performance and balance
of
both the Power Amps
and the Speakers
in
your Audio System. Careful attention to tuning will provide the best sound and a
longer life for all
of
the components.
1.
Input
Controls: Knowing the output Voltage from the Source Unit will allow you to set the Input
Controls before physically installing the Amp
in
the car. If the Source Unit output Voltage Specification is
4 Volts, start by setting the gain controls to about 5 Volts before installing the Amplifier.
2.
Mono Switch: The Mono switch is
in
the OFF Position when the Amplifier is used in Stereo.
The Mono Switch will be
in
the ON Position when the Amplifier is
in
the Mono Mode.
3.
Crossover
Points:
The Crossover Points will be adjusted before installing the Amplifier.
The Crossover Frequency
is
selected based on the speaker size, system configuration, and the amount
of
power applied to each speaker. The smaller diameter speakers will typically be crossed over at higher
frequencies than larger diameter speakers will
be.
Smaller diameter speakers with less power applied can
be crossed over at a lower frequency.
High Pass Filter: The high pass filter
is
continuously variable between 30Hz and 500Hz, and typically
applied to front and rear Satellite Speakers.
