Product Description
FOUR.1i - In-dash Equalizer with Aux Inputs
If your performance car audio system is designed for maximum sound quality and maximum control, then the FOUR.1i is the car audio processor for you. Designed to be the world's first professional quality in-dash equalizer, the FOUR.1i boasts such features as 13 volt signal capabilities, a master volume control, and auxiliary inputs for secondary sources. In addition, five equalization controls give just the right amount of control for the user. AudioControl's line of in-dash car processors offer features and functions that allow you to adjust and tweak your performance car audio system from the convenience of the driver seat. Included are features like equalization, electronic crossovers, master volume control, and high voltage line drivers.
Key Features:
Graphic Stereo Equalization:
The FOUR.1i turns the dashboard of your car into a mini-mixing board, just like those in a recording studio. The FOUR.1i 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 specially 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!
Pre-Amp Line Driver:
Talk about your ironies. To operate with maximum dynamic range and the best signalto-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.1i 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.1i 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.1i makes hook-up a snap!
Balanced Inputs & Outputs:
The FOUR.1i uses a unique balanced differential input circuit that helps cancel any noise that radiates into the signal path between the source unit and your FOUR.1i. The FOUR.1i then sends this balanced signal downstream to another processor or amplifier that has balanced inputs (blatant plug for AudioControl products) which will keep it noise-free.
