JL Audio Marine Monoblock Power Amplifier - M1400
JL Audio Marine Monoblock Power Amplifier, Model M1400
Key Features:
- 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 - Preamp Outputs
Pass-through pre-amp outputs permit interconnection of multiple amplifiers (except M6450) - 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 source units - Advanced Rollback Protection
Borrowing a page from the “Slash” amplifiers’ bag of tricks, the M-Series amplifiers employ advanced thermal and low-impedance protection to virtually eliminate annoying amplifier shut-down events
