DESIGN FEATURES

RUBI™(Rapid-Use Branched Impulse) This new proprietary power supply

topology eliminates “power sags” during low frequency reproduction by rapidly increasing the duty cycle, stabilizing the power supply and allowing it to deliver the power required then reproducing low frequencies. Also, greater reserve gate power is stored for low voltage conditions that occur during extreme conditions.

STACT™ (STabilized Apex Current Topology) Reduces power supply

stress by 50%. Typical designs degrade the stereo image due to phase reversal of even-order harmonic distortion that occurs between the inverted channels. In the STACT design, inversion is done at the power amplifier drive stage. Since the fully symmetrical power amplifier produces no even-harmonic distortion itself and all preamplifier circuitry is run completely in-phase, no even harmonic distortion phase reversal occurs.

Trident™ Protection Topology provides three types of protection:

1. Output protection against short circuits or improper loads.

2. Ground fault detection: Shuts down the amplifier when a significant voltage

(>5 Volts) fluctuation occurs between electrical (turn-on lead)and battery ground.

3. Thermal Protection: Puts the amplifier into thermal rollback or shuts the amplifier down in extreme thermal conditions.

Hawkins Bass Control - Fully adjustable subwoofer equalization circuit

providing frequency and boost(“Q”) adjustment for optimum subwoofer performance. A frequency tracking subsonic filter protects woofers from potentially harmful low frequency information and maximizes output in a usable range.

4

Harmonic Bass Alignment™ The 2nd and 3rd order harmonic peaks are

critically aligned to fundamental peaks at low frequencies. This produces tighter, more accurate bass reproduction.

Drive Delay II™ Amplifier section powers up 2 to 3 seconds after the power

supply eliminating turn-on pops. The turn off process is reversed:

Amplifier section turns off first, followed by the power supply.

Output Clipping Indicators indicate clipping on the output stage of the

amplifier. Monitoring the clipping indicators allows the user to achieve maximum Sound Pressure Level without clipping the amplifier.

Dynamically Optimized power Grid™ Power grid is evenly distributed

between primary and secondary power supplies, providing greater dynamics and improved RF filtering.

Chassisink™ All transistors are ideally located and sandwiched between the

circuit board and the heatsink to provide cool efficient amplifier operation.

Differentially Balanced RCA Input eliminates ground loop related noise in

the audio.

Continuously Variable Crossover Network : 12dB/Octave highpass

crossover variable from 50 to 200 Hz and 24dB/Octave lowpass crossover variable from 40 to 160 Hz.

Flexible Input Level Control allows 300 mV to 5 V input sensitivity.

Symmetrical Discrete Balanced Class A Drive Boards auto-adjust for linear

performance while driving low impedance loads.

Removable Front Spoiler allows for stealth installation of RCA, Balanced

Line, Speaker and Power wiring.

CROSSOVER & PHASE ADJUSTMENTS

The Human Reign amplifiers incorporate an on-board staggered electronic cross-over. No external electronic crossover is necessary. The low pass portion of the crossover can be set independently of the rest of the system.

In many car audio installations, there is a tendency for a ”midbass boom.” Because of their interior dimensions, most cars will resonate or ring at these midbass frequencies. If we design the system so there is reduced output in this region, the final response is very smooth and natural sounding. The HUMAN

Reign has an always on low pass crossover that is independently variable from

40 to 160 Hz at 24 dB/Octave.

For initial crossover setup, try setting the low pass filter to approximately 60 Hz, and the high pass filter on the rest of the system to approximately 100 Hz.

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

Phase Switch

In many car audio systems placement of the subwoofers can cause them to be out of phase with the rest of the system. This may cause poor subwoofer performance due to varying arrival times. To eliminate this the Human Reign incorporates a 0 to 180 phase switch. By playing low frequency music and experimenting with the subwoofer phasing better sound quality and bass imaging may be obtained.

Hawkins Bass Control - Theory and Use

Hawkins Bass Control(parametric)is a unique

subwoofer control circuit included with the Soundstream

Human Reign amplifier. It is capable of removing subsonic energy in program material while boosting subwoofer frequencies. The circuit consists of two controls. One adjusts the frequency of operation and the other adjusts the range of boost. With both controls adjusted fully counter-clockwise, no boost is applied and the amplifier is flat in response down to 20 Hz.

FIG. 1 BASS CONTROL

The frequency control (Hz) adjusts the starting point of the subsonic filter. On the

Human reign the high pass filter has two frequency ranges. When the bass control switch is set to “SUB SONIC”, the high pass filter frequency can be adjusted from 13 Hz up to a maximum of 30Hz. In this setting, no boost “Q” control is available. This control is useful for setting the lowest frequency that your subwoofer will see (see figure 1). When the bass control switch is set to “HAWKINS BASS CONTROL”, the high pass filter frequency can be adjusted from 30 Hz to a maximum of 70Hz. In this setting, there is an available boost control of 0 to +9dB.

FIG. 2 VARIABLE “Q”

FIG. 3 VARIABLE HIGH PASS

The Boost control adjusts the amount of level

applied at the set frequency.

This is adjustable from flat (0dB) to +9dB. (See figure 2)

FIG. 4 VARIABLE BOOST

When the Boost is set to 0, Hawkins acts as a sub-sonic filter only. (See figure 3) The simple act of removing potentially harmful low frequencies can improve system output by as much as 3dB.(see figure 4)

11

Application

Subwoofer drivers in general have excellent power handling characteristics over their operational 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

FIG. 5 LIMITED EXCURSION

bandwidth. These potentially damaging signals can be removed by adding a subsonic filter. Figure 5 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 Hawkins’

“Hz” control is as follows:

1. Adjust frequency and boost control to full CCW position.

2. Set the bass control switch to “HAWKINS BASS CONTROL”.

3. While listening to music with strong bass content at a moderate level, slowly adjust frequency control clockwise. Listen for a reduction of bass response. Now, rotate frequency control slightly backwards. This serves the purpose of removing the “subsonic” bass energy.

With Soundstream’s Hawkins Bass Control, the boost and frequency control can provide virtually any combination of boost and cut to suit your designs.

So, Hawkins Bass Control can provide the

“tailoring” needed for any type of “assisted” design and any woofer in any type of installation.

CIRCUIT BREAKERS AND FUSES

EXTERNAL

Like all audio components, the Human Reign amplifier must be fused near the battery. A fuse or circuit breaker must be located within 18” of the battery. This will prevent a fire in the event of a shorted cable. See the chart below to determine the correct fuse value.

INTERNAL

The Human Reign amplifiers are fused with an automotive-type or Maxi-fuse. In the event of a blown power supply fuse(s), replace with the correct value fuse found in the chart below. Never replace the fuse with a higher value than what

is supplied. This may result in amplifier damage and will void the warranty!

INSTALLATION AND MOUNTING

AMPLIFIER LOCATION

The Human Reign amplifiers employ highly efficient circuitry,a customengineered 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.

MOUNTING THE AMPLIFIER

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

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

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

WIRING

a. Run and connect the audio signal and remote turn-on cables from to the amplifier form the source unit. b. Carefully run the positive cable from the amplifier to the fuse or circuit breaker within 18” of the battery.

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

d. 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.

e. Double check each and every connection!

f. Re-connect the fuse or circuit breaker.

POWER UP

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

15

LEVEL SETTING

The input level is adjusted by means of the input level control located on the control panel 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 the distorted input. By setting all components to reach clipping at the same time, you can maximize the output of your system. For the

Human Reign amplifiers, follow these steps for setting the input levels:

1. Turn the amplifier’s input level to minimum position (counter-clockwise).

2. Set the source unit volume to approximately 3/4 of full volume.

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