JL Audio Slash v2 250/1v2 | Monoblock Amp Guts | 250W RMS | 4K Ultra HD
The remarkable R.I.P.S. System ensures consistent power delivery over a wide range of battery voltages and load impedances. R.I.P.S. stands for "Regulated, Intelligent Power Supply" and is a central feature of JL Audio's 'Slash' and HD amplifiers. "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). This contrasts with conventional, "unregulated" power supplies, which allow rail voltages to sag in direct proportion to drops in the supply voltage. This can result in significant power losses when battery voltage decreases, even if those voltage dips are short in duration. This manifests itself audibly as increased distortion. With a JL Audio R.I.P.S. equipped amplifier, the rail voltage and clean power output remain completely stable in real-world systems, resulting in superior fidelity and stability. 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). Conventional amplifiers are designed to produce optimum power at a particular impedance (2 ohms, for example). When asked to run above that impedance (say, 4 ohms), these amplifiers lose power (half their power from 2 ohms to 4 ohms). This will not happen with a JL Audio HD or 'Slash' amplifier because the R.I.P.S. System detects the actual impedance being driven and adjusts the amplifier's operation to deliver optimum output. The entire process is seamless, automatic, and results in incredible dynamics for satellite channels and consistent power output for a wide range of subwoofer configurations. It also takes into account the real impedance of the system, rather than relying on often inaccurate assumptions based on a speaker's rated impedance. The bottom line: Optimum power, at any impedance between 1.5 ohm and 4 ohm per channel, at any vehicle voltage between 11V and 14.5V. JL Audio's exclusive Advanced Rollback Protection circuit monitors the amplifier's thermal condition and adjusts amplifier operation to eliminate annoying amplifier shut-down events. Should a JL Audio amplifier equipped with Advanced Rollback Protection reach an unsafe operating temperature, a special circuit rolls back peak power output, without changing gain, until the amplifier cools down to a safe operating temperature. The red "Thermal" LED will light to indicate this condition has been reached. Once the amplifier cools down, the circuit restores full peak power output and the red "Thermal" indicator reverts to its normal state. The operation of Advanced Rollback Protection is inaudible in most cases, but it ensures that your music keeps on playing, even under the most demanding conditions. While Class D amplifiers are well known for outstanding efficiency, they have also been known for less than spectacular sound quality due to weak damping of the driven load and poor power regulation. These factors are critical to subwoofer fidelity as they relate directly to the amplifier's ability to control the motion of the speakers. JL Audio's Patented Class D output circuit utilizes a discrete control section and a unique feedback loop design that results in outstanding power regulation and a damping factor greater than 500 at 4 ohms (250 at 2 ohms). This is vastly higher than other Class D designs and also higher than most Class A/B amplifiers. The benefit of this exclusive JL Audio technology is tight, clean bass reproduction with the efficiency advantage of Class D. It is a package tailor-made for serious bass performance. Most car audio amplifiers rely on big lumps of metal that do a good job of storing heat, but not such a great job of getting rid of it. RealSink equipped JL Audio amplifiers feature real cast-alloy heat sinks with vertically-oriented fins. This design is far more effective than the lump-of-metal approach, utilizing the physics of convection and radiation to more effectively exchange heat with the surrounding air. The design of these heat sinks was refined through extensive finite-element analysis, resulting in amplifiers that keep their cool under the most demanding conditions. Dimensions: (LxWxH): 10.25" x 9.25" x 2.27" (260mm x 235mm x 58mm) 4-gauge power and ground leads. Fuse Value: 30A, MAX draw 40A. RMS Power Rating (11V-14.5V): 4 ohms: 250 watts x 1 chan. 3 ohms: 250 watts x 1 chan. 2 ohms: 250 watts x 1 chan. 1.5 ohms: 250 watts x 1 chan. MADE IN CHINA
