RUBITM(/Japid-_Use Branched !mpulse) 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 when reproducing wide band frequencies. Also, greater reserve gate power is stored for low voltage conditions that occur during extreme condi- tions.

STACTTM (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.

TridentTM 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 signifi- cant voltage (> Welts) 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.

Fully Balanced Inputs for professional-quality performance and noise cancellation. The 6-pin DIN plug carries (k) signal information for Left and Right channels, audio ground, and * 15 Vdc to operate the Soundstream BLT / BLT4 Balanced Line Transmitters.

Harmonic Bass AlignmentTM The 2nd and 3rd order harmonic peaks are critically aligned to fundamental peaks at mid and low frequen- cies. This produces tighter, more accurate bass reproduction.

Drive Delay II TM Amplifier section powers up 2 to 3 seconds after the power supply eliminating turn-on pops. 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 GridTM Power grid is evenly distributed between primary and secondary power supplies, provid- ing greater dynamics and improved RF filtering.

ChassisinkTM All transistors are ideally located and sandwiched between the circuit board and the heatsink to provide cool efficient amplifier operation.

Differentially Balance RCA Input eliminates ground loop related noise in the audio.

Flexible Dual Input Level Control allows 300 mV to 5 V input sensitivity. Separate Left and Right level controls allow user to optimize system level control.

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.
