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 to reproduce 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 desig

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. 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 sup

Hawkins Bass Control - Theory and Use Hawkins Bass Control (parametric) is a unique subwoofer control circuit included with the Soundstream Human Reign Unleashed amplifiers. 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

Application Subwoofers 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 exc

INSTALLATION AND MOUNTING AMPLIFIER LOCATION The Human Reign Unleashed amplifiers employ highly efficient circuitry and a custom-engineered heat sink 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

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
