ALPHASONIK WAS FOUNDED IN 1976 WITH ONE MISSION, TO

BRING STATE OF THE ART PERFORMANCE TO THE CAR AUDIO

ENTHUSIAST.

In those early years we pioneered such ground-breaking technologies as amplifier fan cooling and high voltage signal transfer which remain a benchmark in high-end audio.

Today, the new Alphasonik is committed to pushing the envelope with regard to technology, quality and value. Our electronics feature audiophile parts and circuit topology designed to let the full musical experience come through, loud and clear. Our loudspeakers employ the latest high technology materials and processes such as carbon reinforced woven glass and titanium vapor deposition to deliver your music with tremendous impact, dynamics and resolution.

We stand behind our quality with one of the best warranties in consumer electronics. Compare Alphasonik car audio products against anything competition has to offer. We’re confident you will come to one conclusion...

Thank you for purchasing this Alphasonik product. Alphasonik products are specifically engineered and designed for the mobile audio environment. This manual contains important information about installation, set-up procedures and integrating your new Alphasonik product into your vehicle. With proper care and installation, your new product will provide you with many years of high performance listening enjoyment. We recommend having an Authorized Alphasonik Dealer install your new product for optimal performance and to take advantage of our warranty program. Before installing your new product, please read through the manual to fully understand the application.

Before making any electrical connections, make sure that you disconnect the battery’s ground cable to prevent the possibility of short circuits or damage to your electronic equipment. If your vehicle’s stereo (head unit) comes with an Anti-theft code, DO NOT disconnect the battery. If you have the access code for the stereo (head unit), please refer to the vehicle’s owner’s manual.

There are basically three types of equalizers: graphic, parametric, and a hybrid of these two, often referred to as paragraphic. Additionally, there are passive equalizers, which have no gain, active gain pre-amps, which have a again stage usually with a volume control, and booster equalizers which we won’t consider here since they are inferior passive equalizers with inexpensive IC amplifier built-in.

As in state-of-the-art home audio systems the optimum system requires a dedicated pre-amp with enormous gain to drive the various power amplifiers. Since home audio amplifiers do not have adjustable sensitivity, they require a high output pre amplifier to drive them to maximum levels.

The unit is the first production pre amplifier to incorporate a specific bandwidth parametric equalizer with shelving control with 18dB boost or cut on its four bands, it can compensate for the four acoustic anomalies unique to the automotive environment. This unit easily becomes the “Mission control Center” of any high end automotive sound system.

CROSSOVER CONTROL

It is recommended that the MID BASS / MID / HI frequencies be set at center position and that the SUB frequency set at around 60Hz. One of the best features of this unit is that it allows the listener to adjust each band exactly to his/her own satisfaction. PLEASE NOTE: That the correct settings depend very much on the overall system itself and the individual musical taste of the listener. Please check the settings for each band carefully before completing the installation.

SET-UP ADJUSTMENT

Before Turning On: Turn the unit volume to minimum, adjust the input gains to minimum, Turn the source unit volume to minimum, Set EQ controls to flat (12 o’clock).

System Turn On: After completing all wiring and signal connections you can now turn the system on.

Adjust: Raise volume of the unit to maximum. Adjust left and right input gains of the unit until half way between minimum and maximum.

Gradually increase source volume until clipping occurs. Begin gradually increasing input gains until distortion is audible, then reduce slightly, system should be extremely loud at this point. Turn the volume control down to minimum and back up to comfortable level.

NOTES: Set your source volume at one-half to three quarter up and

leave it in it’s position.

Always use your volume as a master (main) volume control. It has better electronics, higher S/N ratio and is more linear than any source unit volume available. If engine noise is audible, try raising the volume on the source unit, and/or check the ground connection on the unit.

Investigate the layout of your vehicle thoroughly before drilling or cutting. Take care when you work near the gas tank, gas lines, hydraulic lines, electrical components and electrical wiring. Do not use the equipment unmounted. Attach this system securely to prevent damage, particularly in the event of an accident or aggressive driving. Do not mount the system so that wire connections are unprotected or are subjected to pinching or damage from nearby objects. Before connecting or disconnecting power connections at the system power terminals, disconnect the +12V DC wire at the battery end. Confirm that your source unit and other equipment are turned off while connecting the input terminals. If you need to replace the power fuse, replace it only with a fuse identical to the provided fuse. Using a fuse of different type or rating may result in damage to the system, which is not covered by the manufacturer’s warranty. Do not install any product where it may be subjected to excessive heat, moisture and dust or where it may be repeatedly kicked, brushed or bumped. Make absolutely sure that the terminals for the products are connected to the proper inputs and outputs from the music source. Never run the wiring on the outside of the vehicle or under it where it can be damaged by road hazards or any moving parts of the vehicle. Use existing wire channels, sills, panels and molding strips inside the vehicle to hide the wiring for safety and a neat appearance.
