In the STACT design, inversion is done at the power amplifier drive stage.

Theory and

Use

The

RUBICON204,404

and 604 amplifiers incorporates an on-board staggered electronic crossover, with full range RCA outputs to drive an external amplifier. No external electronic crossover is necessary. The high and low pass portions of the crossover can be set independently of one another.

In many car audio installations, there is a tendency for a Because of their interior dimensions, most

midbass frequencies. If we design the system so there is reduced ouput

cars will resonate or ring at these

boom.”

this region, the final response is very smooth and natural sounding. The

high pass crossover is independently variable from 65 to 220 Hz at 12

dB/

Octave, and low pass crossover is independently variable from 30 to 120 Hz at 24

dB/Octave.

(12 dB/Octave lowpass on RUBICON204)

For initial crossover setup, try setting the low pass filter to approximately

60 Hz, and the high pass filter to approximately

100

Hz. Change the crossover points to accommodate a good mixture of frequency response, power handling, and personal preference.

tional bandwidth. This bandwidth is determined by many factors, including driver design, and enclosure type. It is possible to overdrive any subwoofer driver by sending powerful signals outside of its operational bandwidth. These potentially damaging signals can be removed by adding a subsonic filter. Figure 3 shows the effectiveness of the Hawkins Bass Control on woofer excursion in a vented enclosure. The woofer travels 7.5 mm at 10 Hz. With Hawkins Bass Control properly adjusted, this excursion can be reduced to less than 1 mm. This is of great benefit to lowering woofer distortion and increasing output.

Adjustment

An easy method of optimizing your existing subwoofer enclosure with Hawkin’s Bass Control is as follows:

. .

Adjust the boost control to full counter

Set the bass control switch to “HAWKINS BASS

heat sink, and a unique Chassisink construction to maintain lower operating temperatures. Additional cooling may be required if the amplifier is located in a tightly confined area or when driving especially low impedance loads at extremely high levels.

When mounting the amplifier, it should be securely mounted to either a panel in the vehicle or an amp board or rack that is securely mounted to the vehicle. The mounting location should be either in the passenger compartment or in the trunk of the vehicle, away from moisture, stray or moving objects, and major electrical components. To provide adequate ventilation, mount the amplifier so that there are at least two inches of freely circulating air above and to the sides of it.

amplifier employs highly efficient circuitry, a custom-engineered

MOUNTING THE AMPLIFIER

Using the amplifier as a template, mark the holes on the mounting surface.

Remove the amplifier and drill the holes for the mounting screws.

Secure the amplifier to the mounting surface using the supplied hardware.

Run and connect the audio signal and remote turn-on cables to the amplifier from the source unit.

Carefully run the positive cable from the amplifier to a fuse or circuit breaker within 18” of the battery.

Connect the fuse or circuit breaker lead to the battery. Leave the circuit breaker off or the fuse out until everything is bolted down.

Secure the ground cable to a solid chassis ground on the vehicle. It may be necessary to sand paint down to raw metal for a good connection.

Double check each and every connection!

Re-connect the fuse or circuit breaker.

POWER UP

Power up the system and look at the Power LED; there may be a 2-3 second delay from the time the source unit is turned on to the time that the LED on the amp turns on, which is normal. Once the amplifer LED is on and the source unit is playing, you should have sound coming from the speakers.

The input level controls are located on the front of the amplifier. This is a unique dual-stage circuit that adjusts both level and gain. This topology maintains better S/N Ratio even when using sources with minimal output.

In the ideal situation, all components in the audio system reach maximum undistorted output at the same time. If you send a distorted signal to an amplifier,

it is simply going to amplify distorted information. The same holds true if an outboard processor or crossover begins to distort before you have maximum output from the amplifier. By setting all components to reach clipping at the same time, you can maximize the output of your system. For your

RUBICON

amplifier,

follow these steps for setting the input levels:

Turn the amplifier’s input levels to minimum position (counter-clockwise)

Set the source unit volume to approximately 314 of full volume.

While playing dynamic source material, slowly increase the amplifiers’ input level until a near maximum undistorted level is heard in the system.

Once the amplifier is installed and the proper levels set,
