FEATURES AND HIGHLIGHTS
The following section will tell you about all of the nifty
features of your THREE.2. Knowing these features will help
you maximize the performance of your THREE.2 in-dash pre-
amp/equalizer/crossover. You will also score points with your
fellow autosound buddies.
Graphic Stereo Equalization: The THREE.2 turns
the dashboard of your car into a mini-mixing board, just like
that in a recording studio. The THREE.2 has three frequency
controls set at 125Hz, 1.25KHz, and 10KHz respectively. The
frequencies were selected to provide you with a just enough
control to make dramatic improvements in any system.
Para-BASS
®
: You want bass, we got bass. This specially
designed equalizer control lets you adapt the bass response
of any system to your listening desire. Given all of the vari-
ous types of music combined with numerous possible bass
response anomalies in every vehicle, a single control for bass
just doesn’t cut it. It’s like painting a picture with only one
color…BORING!
Input Selection: The THREE.2 provides a “Main” RCA
input on the back panel of the unit. It also provides two
choices for an Auxiliary input. One is on the back panel for a
permanent Aux-in, and the other is located on the front pan-
el. If you just want to be able to plug an iPod in on occasion,
then you can use the front panel 1/8” input. Also, the THREE.2
Aux-ins have been optimized with extra gain to compensate
for weak signals from iPods and other MP3 players.
24dB/Octave Linkwitz Riley Crossover: What is
the benefit of fine tuning your system if you cannot accu-
rately route the proper frequencies to the proper amplifier
channels? The programmable audiophile crossover in the
THREE.2 is the same crossover in many other award winning
AudioControl components. Know who else gives you a 24dB
Linkwitz-Riley in their in-dash EQ? Nobody! This is also a far
cry from the wimpy crossovers that find their way into some
amplifiers these days.
Pre-Amp Line Driver: Talk about your ironies. Am-
plifiers require a high voltage input signal (generally 2 to 5
volts) to operate with maximum dynamic range and the best
signal-to-noise ratio. On the other hand, typical source units
only produce 1 to 2 volts, if your lucky. In a system where
the source unit is located in the front of the car and the
amplifier(s) are located in the rear, the length of the connect-
ing cables can have an negative impact on the strength of the
signal. The THREE.2 includes a line driver that takes the weak
