JL Audio A-Series 6 Channel Mobile Amplifier, Model A6450
The value-packed A-Series amplifiers feature the same patented Class D and Class A/B output technologies as the flagship "Slash" amplifiers. The primary difference is that "A-Series" amplifiers employ a more conventional unregulated PWM switching power supply instead of the R.I.P.S. design used in the Slash models.
- Patented Absolute Symmetry A/B Circuitry
(U.S. Patent #6,294,959)
The full-range models employ this patented technology which reduces distortion and improves power symmetry.
- Patented Class D Circuitry
(U.S. Patent #6,441,685)
The subwoofer amplifiers feature a patented Class D circuit for outstanding efficiency, stability and fidelity.
- Active Crossover Features
Fully variable 12dB/octave filters with detented filter frequency selection controls offer excellent tuning flexibility.
- Bass Control Features
Bass boost circuits are included on all models and can be operated with or without a remote bass controller.
- Differential-Balanced Inputs
Greatly reduce noise and provide compatibility with a wide range of sources, including most OEM systems.
- Advanced Rollback Protection
Borrowing a page from the Slash amplifiers bag of tricks, the A-Series amplifiers employ advanced thermal and low-impedance protection to virtually eliminate annoying amplifier shut-down events.
