Compact, marine-ready amplification from DS18. The NXL-N1 monoblock delivers a peak output of 1050W while providing RMS power of 140W at 4 ohms, 230W at 2 ohms, and 350W when bridged to 4 ohms. Audio tuning tools include a selectable low-pass filter (LPF fixed 50–250Hz), a bass boost of 0–18dB centered at 45Hz, and an infrasonic filter adjustable from 10–50Hz to optimize subwoofer performance. Built for harsh environments, the amplifier uses a 4-layer PCB layout and carries an IPX67 waterproof rating; protections cover overload, DC output, short circuit, and input voltage anomalies. The ultra-compact aluminum chassis in black and red eases installation in tight powersports or marine setups. Based on a full-range digital IR-platform design, the unit undergoes quality verification with AP instruments and includes thermal protection and LED status indicators for reliable, long-term operation.
