Owner’s Enjoyment Manual
Pre-Amp Line Driver:
Talk about your ironies. To
operate with maximum dynamic range and the best signal-
to-noise ratio amplifiers require a high voltage input signal
(generally 2 to 5 volts) . On the other hand, typical source
units only put out 1 to 2 volts, (if you’re lucky!) In a system
where the source unit is located in the front of the car and
the amplifiers are located in the rear, the length of the
connecting cables will also cut the strength of the signal.
The FOUR.1
i
includes a line driver that takes the weak
output voltage of a head unit and increases it up to 20dB (up
to 13 volts peak) and then delivers it downstream to the
amplifier inputs.
Auxiliary Input:
The FOUR.1
i
has an “AUX” switch
on the front to allow you to switch back and forth between
sources.
If you are thinking about adding a video system, or even
that extra compact disc player or DVD player, the FOUR.1
i
makes hook-up a snap!
FEATURES AND HIGHLIGHTS
This section will tell you about all of the nifty features of
your FOUR.1
i
. Knowing these features will help you maxi-
mize the performance of your FOUR.1
i
in-dash equalizer as
well as making you the “Big Cheese” with your autosound
buddies.
Graphic Stereo Equalization:
The FOUR.1
i
turns the
dashboard of your car into a mini-mixing board, just like
those in a recording studio. The FOUR.1
i
has four frequency
controls set at 8000Hz, 2000Hz, 500Hz, and 125Hz. These
controls will make dramatic improvements in any system.
Para-BASS:
You want bass, we’ve got bass. This spe-
cially designed parametric control lets you adapt the bass
response of any system to your listening desire. Given all of
the various types of music combined with numerous
possible bass response anomalies in every vehicle, a single
equalization control for bass just doesn’t cut it. It’s like
painting a picture with only one color . . . BORING!
