The original Slash amplifiers set new performance standards for automotive amplification and became the best-selling premium mobile amplifiers in history. The new Slash v2 300/4v2 Class A/B Four-Channel Full-Range Amplifier build on this legendary technology platform, enhancing it in a variety of key areas, like radically improved thermal performance, a beautiful new stackable chassis design and dozens of tweaks aimed at improving performance, flexibility and reliability. There is no magic and no guesswork here... just pure technology, refined to the last detail.
Key Technologies of JL Audio's 300/4v2 Full Range Amplifers:
R.I.P.S.™(Regulated, Intelligent Power Supply)
R.I.P.S. stands for "Regulated, Intelligent Power Supply" and is a central feature of JL Audio's Slash v2 amplifiers. The remarkable R.I.P.S. System™ ensures consistent power delivery over a wide range of battery voltages and load impedances. Regulated" means that the power supply adjusts its operation so as to maintain the amplifier's rated power output and low distortion operation over a wide range of vehicle voltages (11V-14.5 V). The "Intelligent" portion of the R.I.P.S. System is a circuit that actually monitors output current to optimize the amplifier's output power over a wide range of load impedances (1.5 ohm to 4 ohm per channel). The bottom line of the R.I.P.S. system is: Optimum power, at any impedance between 1.5 ohm and 4 ohm per channel, at any vehicle voltage between 11V and 14.5V.
Absolute Symmetry™ Class A/B Circuitry
All JL Audio full-range amplifiers benefit from an exciting technology called Absolute Symmetry™ to deliver amazing fidelity with extremely low distortion over a wide range of load impedances. To accomplish this, JL Audio amplifiers have a revolutionary Class A/B circuit that employs identical N-Channel MOSFET transistors for push and pull with true buffering from the load impedance. This is accomplished via a patented circuit that reverses the operation of one of the transistors in each pair to achieve absolute power symmetry and extremely low distortion over a wide range of load impedances.
Active Crossover Features
The Slash v2 amplifiers provide a comprehensive tool set to fine tune your system effectively and accurately. The state-variable filter design employed in the Slash v2 amplifier crossover sections allows you to seamlessly switch slopes, easily change filter frequencies and, on some models, even address what frequencies or channels the preamp outputs will pass.- Switchable Slope on all filters:12dB/octave Butterworth or 24dB/octave Linkwitz-Riley alignments allowing for more precise integration of subwoofer and satellite speaker channels.
- Fully-variable frequency selection from 40-200 Hz on subwoofer channel filters with a detented frequency selection potentiometer for precise adjustment by sight or feel.
- Fully-variable frequency selection from 50-500 Hz on full-range channel filters with frequency range switch in "x1" position. Selecting "x10" on the frequency range switch multiplies the filter frequency times ten to allow cutoff frequencies between 500 - 5000 Hz.
- All filters are fully-defeatable for use with external crossovers
Differential-Balanced Inputs
All JL Audio amplifiers feature differential-balanced input architecture to effectively control noise and ensure compatibility with a wide variety of source units, including many OEM systems.
Monolithic RealSink™ plus Advanced Heat Management
Vertical, cast aluminum fins dissipate heat more effectively than typical amplifier designs, without resorting to noisy fan-cooling. JL Audio's exclusive Advanced Rollback circuit further protects against overheating without shutting your music down. |
